  • BOScoin - BOS Platform Revised Plan!

    We appreciated everyone’s continued interest in the BOS Platform and would like to share with you what we have done up to now, and also the plans for the future.

    Below will provide a breakdown of the milestones with more information, however we acknowledge the current plan has deviated from previous plans to release the Genesis Block without the simple Trust Contracts functionality in October, and we have genuine reasons we believe the new approach will benefit the platform as further explained below.

    Up to now, we have believe it is best to walk before you run; especially with a technology with so much uncertainty (although the Bitcoin whitepaper was released in 2008, the technology is still under constant improvement as evident from all the BIPs, especially the current BIP148 with so much uncertainty).

    Stellar’s FBA consensus protocol benefits from the unique quorum consensus approach. The stability of the network may depend on the configuration of the quorums — whereby some cases, the entire network may be out of sync or in worst cases, operating in their own silos.

    For our BOS Platform, we believe a structured quorum configuration will add to the performance and reliability of the Platform and have planned according to this. Due to the new concepts in this space causing uncertainty, we have decided to initially release the Platform in C++, testing various aspects (security, performance, reliability, agility), but also focusing the understanding on how quorum configurations will affect the network as a whole — whereby later we will move to a D language-based Platform to further the performance of the platform (don’t fear, we have a team currently working on the D Platform!). We have also taken into consideration the high interest of the community wanting to use the Platform, and wish this path of development satisfies the general community.

    In parallel to protocol development, we have also identified and will conduct a project setting up a global community supporting the BOS Platform; this will have strong correlation to the quorum aspect of the Platform, and also the betterment of the token in general.

    Although touched on in the above paragraphs, we aim to provide more information on the effect of quorum configurations in a later article — and we aim to have that sooner rather than later. In the meantime, please refer to a our draft concept of the community building piece here:

    Global BOS Community Network

    Private TestNet

    The first of the major development milestones is the Private TestNet, which is in preparation of the BOS Platform TokenNet to be launched by end-September 2017. Testing of the BOS Platform commenced internally within the BOS team on July 25th, 2017 and will run for 5 weeks. It will test the Platform, the FBA Stellar Consensus Protocol written in C++.

    There are 3 main categories of focus for the test: performance, security and of course quorum configuration, where all tests will be conducted by code. Below provides more detail in the actual testing parameters:

    General Protocol Performance:

    • Network latency based on quorums in different regions
    • Different transaction amounts
    • Different transaction values
    • The latency, collision and error rates
    • Network stress testing (consensus algorithm, transaction amounts, transaction values)
    • Horizon server capacity

    (Horizon is an API server for the Stellar ecosystem. It acts as the interface between stellar-core and applications that want to access the network)


    • (We are currently engaging in a security consultancy for this aspect)

    Quorum Configuration:

    • A network with: Basic 1 quorum with 4 nodes 1 Horizon server
    • A network with: 2 quorums in separate regions, consisting of 10 nodes each & Horizon server
    • A network with: 2 quorums in separate regions, consisting of 50 nodes each & Horizon server
    • A network with: 2 quorums in separate regions, consisting of 100 nodes each & Horizon server
    • A network with: 3 quorums in separate regions, consisting of 10 nodes each & Horizon server
    • A network with: 3 quorums in separate regions, consisting of 50 nodes each & Horizon server
    • A network with: 3 quorums in separate regions, consisting of 100 nodes each & Horizon server
    • A network with: 3 quorums in separate regions, consisting of different number of nodes per quorum & Horizon server
    • Note: We will use Amazon Web Servers located in different regions globally to conduct the testing

    Public TestNet

    The Public TestNet allows for the general public to participate in the testing of the BOS Platform. This test will follow the same structure as the Private TestNet above.

    Public TestNet is scheduled to commence by the end of August and will run for 4 weeks. We will provide more details on this as the date approaches, including how to participate and how to actually test the Platform — Please keep an eye out for the communications.

    BOS Platform TokenNet

    The BOS Platform TokenNet is scheduled to launch end of September 2017.

    Alpha TokenNet aims to release the Platform in C++, a web-wallet, and have the BOS Platform on exchanges. We hope that the community will enjoy the freedom of moving completing transactions within the Platform and also exchange with external crypto-tokens.

    There will be associated communications leading up to this milestone including more walkthroughs on how to run nodes, use the wallet, and etc.

    Genesis TestNet

    The Genesis TestNet will aim to test the Genesis BOS Platform, this is planned for mid-December.

    Please read ahead to understand what the Genesis BOS Platform will deliver.

    Genesis BOS Platform

    The Genesis BOS Platform will be the release of the BOS Platform using the Stellar Consensus Protocol written in D, and all run off the BOS Platform’s Trust Contact. We will also be releasing:

    • Trust Contracts
    • mFBA Consensus Protocol in D
    • Congress Budget
    • Transaction Fees
    • Freezing Rewards
    • Block Confirmation Rewards
    • Mobile Wallet

    Genesis BOS Platform is targeting to be released in the beginning of 2018.

    Nebula BOS Platform

    In the not too distant future, we aim to deliver the Nebula BOS Platform, which will include everything in the Genesis Platform, including Proposals and the final Congress Network, and the Self-Evolving Governance System.


    Supporting applications are also in development and more information will be provided later.

    We hope this paints a picture of the path ahead for the BOS Platform for you and would like to reiterate our appreciation for your continued interest and support. We will be in contact soon about the community building activity and other information (and we will!); however in the meantime, please feel free to pop into our slack to bounce healthy conversations with us.

  • BOScoin [BOS] - Smart Contracts & Trust Contracts — Part 1

    {Pre-word: This article has been split into 3 due to the length and ongoing research into smart contracts. Part 1 will look into a general understanding of what smart contracts are and how other blockchain projects have incorporated into their design, Part 2 will look into BOS Platform’s Trust Contracts, and Part 3 will aim to provide some analysis on the design differences}


    Smart Contracts in General

    The concept of smart contracts was introduced by Nick Szabo mid-1990’s where he initially defined contracts as a set of promises agreed to in a “meeting of the minds” to “formalize a relationship”. Then later went to conceptualize how, by integrating digital technology, including cryptographic algorithms, with the idea of contracts, we would be able to create a digital promise which would still perform the four basic objectives of contract design including observability, verifiability, privity and enforceability.

    “A smart contract is a set of promises, specified in digital form, including protocols within which the parties perform on these promises.”

    Smart contracts are believed to improve efficiency with transactions/processes and also remove ambiguity as summarized below:

    Process efficiency

    As smart contracts feed from digital information, upon the conditions met in the smart contract, the agreed next step between parties will proceed automatically, i.e. processing of a bet between parties, or progressing application forms upon receipt of information.

    Remove ambiguity and third party involvement

    Current legal contracts are at times difficult to understand and may be interpreted differently between parties. Smart contracts (in the perspective of blockchains) are currently mainly written in code, and it is meant to be more black-and-white, hence ambiguity in legal contractual language is believed to be removed — this also removes the need for lawyers and/or governing officials to mediate the process.

    Further detail is readily available online (a discussion between members at the Wharton School of the University of Pennsylvania provides a good example).

    Smart Contracts in Blockchain

    Today, with the introduction of blockchain technology and various projects we have seen smart contracts realized in practice — a popular example is the Ethereum project. BOS Platform aims to further the smart contract functionality than currently on offer within today’s blockchain technologies.

    In designing smart contracts, various theories may be applied, and as presented in the next section, many have adopted a Turing-complete concept. Turing complete comes from computational automata theory where there are four major families of automaton: Finite-state machine; Pushdown automata; Linear-bounded automata; and Turing machine.

    BOS Platform adopts the Timed Automata, an extension of finite automata, for development of the Trust Contracts and also Web Ontology Language; as such, for the purposes of this article, we will focus our knowledge sharing on the Turing-machine and finite-state automata concepts for the development and functionality of smart contracts, as well as touching on some other more popular design options.


    Through reading various projects information on smart contracts at a design and architecture level, they appear to lack specificity and detail; this is probably because smart contracts are created to be adaptable to particular tasks and/or are project specific. Instead of trying to understand smart contracts at a general blockchain space, this article will look at specific blockchain projects’ design of smart contracts, where we will hopefully then gather a general feel of smart contracts in a public blockchain space.

    The list of cryptocurrencies below mainly relate to public blockchains’ smart contracts as this relates to BOScoin’s environment of operation.

    Public Blockchain Smart Contracts Notes


    Although the main goal of Bitcoin is the transaction of the Bitcoin currency in its platform, its openness allows smart contracts (with limited functionality) to be built onto the platform. One, for example is RootStock, a project which is built on Bitcoin’s blockchain. The consensus component of the RootStock is conducted via Bitcoin’s network, and adds a Turing complete smart contract on top of it.


    Ethereum smart contracts are designed using a Turing complete concept whereby the smart contracts may run any program (irrespective of the language) provided it has the resource (gas or computational power). Due to this nature the only limit to the smart contract is if the contract is written in a way that causes issues and behaves inappropriately, or not as planned.

    A research by Bartoletti and Pompianu earlier this year studied the design aspects in relation to the operations of Ethereum smart contracts; and in summary they can be categorized into using blockchain, oracle or using a customized algorithm that may feed from blockchain or oracle information.


    Stellar only has simple smart contracts with “built-in token capabilities”. Stellar strives to ensure safety and stability of their system and has hence opted to limit their smart contract functionality.


    Using DPoS, Lisk smart contracts utilize a Turing complete concept with Node.js or JavaScript, however contracts are validated by programmers.


    Monax supports the Ethereum’s smart contracts design, and further allow users to build private blockchains to define specific authorization policies to access the blockchains.

    Monax has defined smart contracts as code representing unilateral promises to provide deterministic computation based on transactions which are sent to the blockchain housed script.

    Monax looks to design smart contracts that are modular, repeatable, and have autonomous scripting which can be used to build applications; They wish their smart contracts to be mixed and matched, and easy to iterate, similar to lego bricks combined with pre-set templates, which can be coded to reflect any kind of data-driven business or engineering logic, or to model relationships and obligations.


    Nxt smart contracts are not Turing complete, but have used a Turing complete scripting layer to create template smart contracts. Users would select the most appropriate template and adjust the parameters to create their own smart contracts. Nxt believes the smart contracts created from these templates should cover most business applications; be easy to code, and ensure safety in the system.


    Tezos employs the Turing complete ideology, however they limit it by time and/or blocks on the blockchain.

    Tezos debates the theorems of Turing completeness that in practice and theory, computers are always bound by its computing resource (i.e. memory or electrical power), and hence will eventually halt.


    Using EVM Turing complete, Qtum aims to tailor this to Bitcoin’s UTXO model, whilst also adopting the Ethereum gas feature and creating their own smart contract language, Qtum Smart Contract Language (QSCL).

    Qtum will have an account abstraction layer, incorporated in their smart contract design, which translates the UTXO-based model to an account-based interface for the EVM.


    EOS Focuses on asynchronous smart contracts which do not require sequential processing of current smart contracts (such as Ethereum), and hence are processed quicker. Unfortunately it appears EOS development in this front are being conducted under the covers until more is progressed.


    Waves are adopting a non-turing complete concept using the Bitcoin scripting for their smart contracts to allow for finite execution times. There are also information on potentially having some transactions being processed off the chain to reduce blockchain bloat (unsure if this will be applied to smart contracts). Once again unfortunately, there is little information available to the public on other design aspects.


    Burrows is the permissionable Smart Contract Engine of Hyperledger. Components of Burrows include:

    • Consensus Engine - Currently using Tendermint’s consensus algorithm, however it aims to have the ability to leverage other consensus engines
    • Application Blockchain Interface (ABCI) - The interface — members are looking to make this component modular
    • Smart Contract Application Engine — validates transactions and applies them to the application state for consensus. Sub-components are: [Application Global State] The application state consists of all accounts, the validator set, and Burrow’s in-built name registry. [Secure native functions] Ground rules and coding policy for all smart contracts to adhere to [Permission Layer] [Permissioned EVM] Uses EVM combined with permission Finite amount of gas allocated for every execution to ensure finite duration [Gateway] Layer allowing clients to interact with the blockchain network and application state

    Other notes from research

    Not exactly another cryptocurrency, however upon research into smart contracts, there are various articles that provide some good information on smart contracts. Below summarizes some functionality limitations and other design considerations for smart contracts:

    • Regulating bugs in code
    • Tax on smart contract transactions (is this required? Potentially remove from article)
    • Sending wrong code
    • Terms in contracts do not cover the complete environment of the agreement, i.e. if external factors affect the practical operation of an agreement, the smart contract will continue to run (in legal contracts, you may rescind the contract)
    • All nodes will execute a smart contract

    On the last point regarding all nodes executing the same smart contract, some entities have incorporated an additional component into their architecture, Cryptlets. The concept of Cryptlets are an off-chain component that execute within a secure trusted container and communicated using secure channels.

    Public Blockchain Smart Contracts Design Aspects Summary

    From the information gathered above, there appears to be 3 categories of findings, Computational Automata design/modelling; Information sourcing and smart contract implementation.

    Computational Automata Design / Modeling

    A majority of projects have incorporated a Turing complete design into their smart contracts. Turing complete in a smart contract sense essentially allows to compute any program regardless of the language it is written in, with the thought of opening the potential of smart contracts functionality to be applicable to any environment.

    The concept of Turing completeness stems from the study of computational theory which the computational ability resembles that of a Turing Machine.

    Some other projects (i.e. Stellar and Bitcoin to an extent) have taken a different approach and not designed their smart contracts to be Turing complete or have created Turing complete smart contracts with limited functionality to uphold the safety and security of their platform.

    An example of where security and safety issues arose from Turing complete smart contracts is the DAO attack — where a hack was made to the DAO code to siphon funds, the security of the smart contract was made vulnerable to attacks as the implementation of the code was not completely understood.

    Information Sourcing

    In order for the implementation of a smart contract, there needs to be some form of input data which the contract processes and, upon certain agreed conditions met, it produces some resulting output. From the information gathered above, the input data appears to be of 2 forms, information from the blockchain itself, and information from some oracle source.

    Information from the blockchain appears to be the most reliable as the blockchain platform has been designed to ensure the integrity and safety of the information, agreed among the community network.

    Data from an oracle source, in contrast, may pose some quality and reliability concerns. How are we to know whether information from oracles are correct? Where is the information sourced from? Who has the permission to update the information? The list goes on.. Of course there may be sites where information is backed by reputable agencies, however who is to know for certain the information is credible?


    At a high level, blockchain is a decentralized system and all nodes essentially run the platform. Some sources have identified potential inefficiency regarding the operations of smart contracts stored on the blockchain requiring all nodes to implement it — if all nodes are implementing the same code, can we say this is an efficient use of resource?

  • BOScoin Update - TokenNet Launch Postponed &Test Results & Wallet Testing

    TokenNet Launch Postponed

    TokenNet launch is not far off now, but unfortunately, delays must be
    made to ensure everything goes right upon launch due to Chuseok. Chuseok
    is one of the biggest holidays in Korea and is just after the intended
    deployment date of TokenNet. We originally did not anticipate Chuseok to
    be this long because the government designated Oct. 2nd
    to be a one off holiday only three weeks ago but we are having a long
    Chuseok this year, 10 days to be exact if you include the weekends from Sept. 30th to Oct. 9th.
    So, we have decided to let the team go home for once and spend the
    holidays with their families. Since not everyone on the team will be on
    stand by mode during that time, we feel it is safer to postpone TokenNet
    launch, especially being the first release of the platform/token.
    Nonetheless, most of our crew will continue further tests to launch
    TokenNet as best as we can. We will let you know of the exact date as
    soon as we are confident that we are able to meet that date. Also,
    as soon as Web-wallet functionality and UX modifications are completed,
    TestNet will be open to the public for you to check it out. We expect to
    open TestNet by the 29th at the latest.

    Test Results & Wallet Testing

    The testing program planned to test the SCP on the AWS network, after when codes are optimized we would move onto the TokenNet environment. Testing in both environments was conducted with various quorum & node configurations in 4 different regions (Virginia, Seoul, Sydney and Frankfurt - 9 nodes in each region). SCP tests are now complete and we have moved on to a mock TokenNet (TokenNet will be the replication of this mock TokenNet on the actual network) testing which we will focus on network stability based on stress testing (summary of test results are below for your reference). 

    Our initial SCP tests experienced high error rates when heavy traffic was injected to the network but our engineers fixed the problem by optimizing horizon configurations in sequencing the transactions. As of now, we are experiencing a 0% error rate but Virginia seems to drop out due to debugging messages that deplete the storage space for its server. We are currently working to resolve this matter and current thoughts believe the issue is due to the physical distance that cause high latency which will lead to less priority for any transaction coming out of that region. It takes at least 5 hours to run a single test so hence a slower than preferred progress rate, but we are working around the clock to fix it, so please do bear with us. 

    High level summary of results:

    • Quorum Configuration
      • Tested with 4 regions, 9 nodes and 1 horizon with each region - Virginia, Seoul, Sydney, Frankfurt - but Virginia seems to disconnect from the network for reasons yet unclear.
      • Restoring protocol to synch Virginia back to the network did not function properly - needs to be checked.
      • Despite the disconnection, the rest of the network remains stable and fully functional.
      • Network stability seems to increase with more nodes in the network.
    • Transaction Error Rates
      • Initially we were experiencing an exponential increase in the amount of errors proportionate to the amount of concurrent levels but after interrogating the code and protocol with further tests, we were able to keep the number to 0% for tests below the concurrent value of 300.
      • Error rates slowly rise if the concurrency value is beyond 300 and rises at a faster pace beyond 800 but such heavy traffic seems unlikely for TokenNet network environment. Error rate = failed transactions including transactions unprocessed for 60 seconds / all transactions
    • Latency
      • With the high error rate, we experienced 2~10 TPS, but once fixing the problem, we are getting around 20~30 TPS. Efforts are being made to increase transaction speed.
    • Other
      • Various codes from the Stellar Consensus Protocol were optimized to align to our TokenNet design such as:
        • Horizon/Sequence number
        • Change of TokenNet configuration such as issuance, base reserve, transaction fee etc.
      • External API matching and compatibility test
    • Web-Wallet 
      • Web-wallet functionality tests and UI/UX modifications are ongoing. A test version Web-wallet will be made public along with TestNet release by the end of next week.
      • We have engaged with a couple of web security firms and asked them to look into our Web-wallet security. We are waiting for results and hopefully we will receive some feedback by next week.


    Mathematics Session

    The BOS team engaged Dr. Jonghwan Lee, a Ph.D of Applied Mathematics from KAIST, to conduct 4 x 2hr sessions to further our understanding on the Stellar Consensus Protocol commencing Aug 28th, 2017. The first two sessions was to confirm our understanding on the Stellar Consensus Protocol Whitepaper; and the last 2 sessions were for us to interrogate the logic validity and also discuss on various design considerations for the BOS Platform. The team found the sessions to be very useful to bounce ideas on the undersanding of the Stellar Consensus Protocol and how it will be integrated within the BOS Platform. We would have attached a couple of photos of the session but Dr. Lee is extremely shy so we will only give you some key take-aways by individuals in our team. 

    "I now have a much better understanding of the quorum concept in the SCP - it is not a static definition which I was confused with at first. Having the sessions has helped me reach this understanding." - Hankyeol Tschoe

    "Having the sessions has allowed me to better understand and translate the intricate logic behind the consensus mechanism, especially regarding v-blocking." - Aston S. Nam

    In the next newsletter, we will let you know of the sessions on Timed Automata theory that we are currently having.


    Design Update & Homepage Refreshment

    As mentioned in the previous newsletter, we are in the process up updating our homepage in preparation for TokenNet!

    The main changes will relate to a design overhaul with the new BOScoin concept and we would like to take a little time to address the Design Identity of BOScoin that will be embedded in our new homepage, and future BOScoin products.

    The conventional shape of a coin is a circle but we wanted to incorporate the blockchain aspect into BOScoin's visual identity. A block is a square seen from the front but we wanted to give it twist and take a look from a different point of view. The square that is the block becomes a hexagon seen from an elevated angle, hence the hexagonal shape.

    The hexagon also resembles a single honeycomb by itself but put together, a beehive which symbolizes a decentralized ecosystem.

    The B inside represents BOScoin, and is also designed to resemble a chain.

    Dots on the front of our renewed homepage will start from a hexagon but will continually transform its shape to illustrate the evolving network/ecosystem. Please, don't be shy and tell us what you think.

    Below are some initial design work we are considering for our refreshed homepage:


    Have You Met...Hyonam Lee


    Hyonam is the chief designer for BlockchainOS and has been with the team since June. He has created and redefined the entire design language of BOScoin since joining the team, which includes the new homepage as well as the Web-wallet that will be launched soon. Hyonam originally studied fashion design and has spent some time in the fashion industry after finishing his studies. He later joined forces with a few freinds, set up a venture business where he was in charge of overall design for the firm - that is where his interest in web design sparked. Although Hyonam initially did not consider web design as a career, after so many unsatisfactory attempts in creating the firm's homepage by subcontractors, he decided to learn coding himself and that has stuck ever since. Following the venture business, he pursued a career in web design with anagency where he became the art director and project manager for big projects by companies like KT and Samsung. With the agency, Hyonam won several prestigious awards for his practical yet artistic work. Working in the IT industry, Hyonam's interests in blockchain grew and he wanted to be involved in a deeper, challenging and consistent project. The BOScoin team, being the first and only to have successfully managed a fundraiser so far in Korea, seemed like a good destination. BOScoin's prospects as a leading cryptocurrency led Hyonam to decide in joining the team as he can reach as many people around the globe through his work. 


    Hyonam's take on Blockchain

    Hyonam considers blockchain technology a tool of making the world more transparent and secure. Despite the current price volatility of cryptocurrencies, blockchain technology is here to stay in the long run and he is particularly excited with the BOScoin project. Hyonam wishes his work to be a positive influence on the development and value of BOScoin.


    Random Interesting Fact

    Hyonam's eventual goal, at a much later stage in life, is to become an architect. He wishes to build homes and design the interiors from scratch that convey his designing philosophy. A Passive House - an environmentally friendly house where energy consumption is minimized - is what he dreams to build.

  • BOScoin [BOS] Development Update - Test Web-Wallet & TokenNet Development Tests

    Development Update Happy Chuseok to everyone from the BOScoin team! We realize most of our contributors and subscribers do not have anything to do with Chuseok, which is a national holiday quite similar to what is thanksgiving in the US, but we thought our holiday sentiment could extend to you anyways:) The team has been working on tests and problems we mentioned before throughout the holidays nonetheless, and we do have some good news. Replacing Virginia to California proved to be fruitful and we are experiencing no disconnections. Error rates, which is defined as the failed transactions including transactions unprocessed for 60 seconds divided by all transactions, were also kept below 0.06% with an increased concurrency value of 400. This is great improvement compared to two weeks ago when a concurrency value beyond 300 returned a rapid rise in the error rate. Although these tests may seem unimportant, it allow us to better understand the network and enable us to deal with the situation more systematically, if any problems were to occur. It provides us with an idea of how the network behaves if anything goes as unexpected and where to look at to fix the problem once the network goes live.  We have also been working to increase the performance of the network. We have proven that more validating nodes increase the stability of the network by comparing a 9 node network to a 36 node network on our TestNet. Although this does not necessarily increase speed, a more stable network can be achieved. TPS fluctuation seems to lessen with more nodes and since we are testing on a harsh environment, we expect speed to improve when TokenNet is launched. Below is a short summary of what we have covered and screenshots of the results :

    TokenNet Development Tests

    • Replace Virginia to California - Increased network stability with no disconnections 
    • Decreased error rate with a concurrency value up to 400 (below 0.06% at 400)  


    Test Web-Wallet We would like to extend our thanks to everyone who have and are participating in testing our test Web-wallet. We have received many feedback and are currently working to reflect your comments. Modifications are constantly being made so we would still appreciate if you could provide input in improving the test Web-wallet. The test Web-wallet still needs to move to the TestNet and we will let you know when we do, but at the moment, please let us know if you see anything unfit regarding functionality, user-friendliness, design or any other aspect you wish to see improved.


    BOS Platform Foundation Announcement

    On Friday, November 10, 2017, there was a temporary failure of the BOScoin network causing the blockchain consensus to fail. The team has been working on recovery during the weekend and has recovered the wallet balances for all accounts, the network was successfully restarted on November 12, 2017 at 15:00 (GMT), and is now running normally. However, only the wallet balances were recovered without the transaction history. The transaction history is kept separately and we are in the process of reviewing the recovery plan. More detailed information will be shared after inspection.

  • BOScoin [BOS]  IMPORTANT ANNOUNCEMENT - Distribution Status, Distribution Schedule, Community Management Updates & More

    On Friday, November 10, 2017, there was a temporary failure of the BOScoin network causing the blockchain consensus logic to fail. This was announced ( and we recovered the blockchain to the last prior stable state, which included all balances, but did not include any transaction history. On Friday, November 17, 2017, we issued this announcement ( notifying the community there was an issue with the manual transfer of transaction fees to public addresses via a script which began processing at 12:25 GMT, 17 Nov 2017 and was halted at 15:04 GMT. This error was caused by a misplaced decimal in the code, which resulted in the distribution of 34 Million BOS to 1418 public addresses. The CTO and other senior management have evaluated the situation, and have decided on the following course of action.

    All public addresses will be reset to a token balance that includes all transfers conducted prior to the online wallet going off line at 15:04 GMT, but will NOT include the transaction fees transferred by the script in error. There will NOT be transaction history after the blockchain is reset. This solution will negate the faulty transaction fees transferred by the script, while at the same time keeping any transfers between public addresses prior to the online wallet being put into maintenance mode. The online wallet ( will be back online by 15:00 GMT 21 Nov 2017.

    We sincerely apologize for the complications caused for two consecutive weeks. The first error was due to a problem with the code and the second one was clearly a human error. Our development team will improve the code reviewing process as well as testings prior to the actual implementation of the code. We promise such mistakes will not be made again in the future.


    Before you email [email protected] asking if you’ve received your coins, please check your public address balance at one of the below websites after 15:00 GMT, 21 November 2017. These websites were created by community members. created by dahammer created by bosradar created by boschain

    Singapore Trip 13–17 Nov

    Pictured — Wouter and Hankyeol

    Last week we participated in the Singapore Fintech Festival and checked out the international atmosphere surrounding Fintech, especially in the Blockchain scene. We had a few prearranged meetings with potential partners and the Fintech Festival wasn’t the main reason why we went to Singapore but it was nice to go out of South Korea and see how fast the industry is moving forward. We also participated in the Inclusive Blockchain Conference hosted by Singapore University of Social Sciences where Vitalik Buterin also had a brief session. Other prominent figures such as Toby Hoenisch from TenX, Los Luu from Kyber, Bobby Ong from Coingecko, Joseph Lubin from ConsenSys and Patrick Dai from Qtum also participated as panelists. Although we did not have a speaking session, it was good to see and learn the challenges others are facing as well. The main reason to go all the way out to Singapore was to see our potential partners and the business they are conducting and we are pleased with some of the progresses we have made. The most progress came from payment and security companies but as some of you may realize by now, we only publicize what is certain so we will update the community in the near future regarding any potential partnerships that may come from this conference.

  • BOScoin [BOS] Change Of Policy

    Change of Policy

    Due to the small amount of BOS distributed to individual accounts, the transaction fee distribution schedule is immediately changed to once per month. The first distribution under the new schedule will be on the 6th of December and will continue once per month on the first Wednesday until the release of BOSnet. 

    As a reminder, only the top 3,000 wallets holding more than 10,000 BOS will receive a portion of the transaction fees equal to the number of units they hold, 1 unit is equal to 10,000 BOS.

    Thank you for your trust and continuing support.

  • BOScoin Newsletter - Token Distribution Status, Exchange Community Vote, & More

    Happy holiday season, fellow BOScoiners!

    Token Distribution Status

    We are continuing to distribute tokens twice a week. We’ve distributed to 55% of all users, but many of the remaining users are very small bounty hunters. We have 27% of the funds remaining to be sent, because they have not been requested. We are processing requests as we get them. Please, if you haven’t already, claim your tokens!

    Monthly Transaction Fee Allocation

    The monthly transaction fee was distributed last Wednesday on the 6th. The 3,000 wallets with the greatest BOScoin balance, who also have more than 10,000 BOS received their allocation of transaction fees. Please check your wallet at to see how much you received. If you did not receive any transaction fees, then you did not meet the requirements for this allocation. As announced earlier, we plan to distribute transaction fees every first Wednesday of the month unless it is a bank holiday, so the next distribution will be on the 3rd of January.

    Exchange Community Vote

    Announcement Regarding Kucoin vote, Bounty program and Lottery

    Go to and vote for BOScoin listing. It costs 0.1 KCS, but if you fill out the google form below, you will receive 2 BOS in your BOScoin wallet, and the chance to win 1,000 BOS. 10 participants will receive 1,000 BOS no matter what! But if we win the vote and get listed on Kucoin, then 10 more lucky participants will receive 1,000 BOS!

    You can find the BOScoin wallet at to create a Public Address. Ensure you save your Secret Seed! It can’t be recovered! Also remember you can’t open the wallet until you have at least 0.1 BOS deposited.

    One application per email address, requires proof of vote, all duplicate submissions will be discarded.

    We will look at the total number of valid votes at the end of the contest on, and at our discretion, we will determine which bounty applications are fraudulent and discard them. We will look at the Public Address submitted, email address, and proof of vote to determine which bounty applications are valid and which are not. Only submit a bounty application after you have successfully voted, using the email address registered with, and send proof of vote from that vote. Using one public address for multiple bounty applications is acceptable, but will increase the likelihood some of your bounty applications could be thrown out, if we have more bounty applications than votes.

    Be sure to vote and apply before the vote is over, we will not accept applications received after T+1 hour. Below is the link to the application form.

    Current Status

    We got over 25% of the total votes as of now and have a clear lead but others are catching up quickly so we’d have to see until the very end. Let’s not drop our tensions just yet.

    We’d also like to take this time to thank a few of the power houses in the community for donating their time and sometimes eth in helping to drive the vote. chef_bedo, moonchaser, bosradar, bronson ksr, prokopvocadlo, cryptolanka, mio, neurocrypt, dahemmer, heru, t-spark, wouterb, HJ de Vries. Apologies if we left anyone out. We really appreciate all the community involvement in this vote.


    The BOS Platform Foundation will be conducting a financial and technical audit regarding the development of the project, just to keep everything in check. The audit will be conducted by one of the Global Top 4 Accounting firms and we are currently in talks with a couple of them to carry out the audit. We will choose one firm by this week and hope to have the audit completed by year end. The primary purpose of the audit is to ensure all the financials and technicals are in order for FINMA (Swiss Financial Market Supervisory Authority) so that they can keep us in check.

    We will no longer be actively engaging with users in the un-official telegram groups at the end of the year, or checking telegram PMs. Everyone using telegram to communicate with the BOScoin team should register for an account at The community forum is our primary means of communication, and over the next year we will slowly phase out other platforms for official communication with the team.

    Exchange Updates

    Congratulations everyone! We won the community vote with 35.9% of the total votes. We are in contact with Kucoin about our listing, but it will take time. We will notify the community once the listing date is made public by Kucoin. 

    As stated in the Kucoin Bounty and Lottery notice (, we scrubbed the bounty applications, and removed duplicate entries. There were a few applications with Secret Seeds given, and we've reached out to those individuals to email us their BOScoin Public Addresses (Starts with "G"). Once the list is complete, we will send everyone 2 BOS to the BOScoin Public Address given. The first 10 lottery winners will each receive 1,000 BOS. There will also be a second group of 10 lottery winners each receiving 1,000 BOS once we are listed on Kucoin. We would also like to give special thanks to those who have helped selflessly, encouraging other members to vote.

    The lucky winners who will receive 1,000 BOS are :

    We are in active communication with many exchanges. The current regulatory environment in multiple jurisdictions is making it difficult to list on exchanges. Winning the Kucoin vote is a major victory for our project, and we thank everyone who helped us win the vote. We are continuing to push for exchange listing on many exchanges. We hope you understand that we won't be able to notify the community about exchange listing status due to none disclosure agreements. Once an exchange makes a public announcement, then we can notify the community, but not before.

  • BOScoin [BOS] - Development Updates, Exchange Updates & Distribution Status

    Development Updates

    Although we can pretty much agree that creating an ERC20 token would have been much easier, we also hoped to learn and gain from the experience of running a separate consensus protocol and this would also help in creating our own consensus protocol. As you probably know, BOScoin's current consensus protocol is more or less identical to Stellar's Federated Byzantine Agreement, or SCP, but we have been working to modify FBA to better suit our project. We are currently testing an Advanced Federated Byzantine Agreement model and proof of concept is currently under way, as well as a full request code review. A second model has already completed code review and testing of reaching consensus within a quorum. We are also trying to downsize the traffic of FBA to improve latency by gathering up all traffic within a timeframe to a single bundle.

    Trust Contracts will be programmable and approachable using ontology and below is a simple diagram on how to understand the flow. Testing of prototypes are currently being made for the flow to work in use cases such as transfer and raising of funds.

                                             Trust Contract Flow

    Exchange Updates

    Listing on exchanges is a process, and these things take time. Any anxiety our community members are facing is the result of being a part of a startup developing a new blockchain platform, so anyone considering buying our token should be interested in the long term prospects of BOSnet, and have some patience. Don't focus on short term gains. Our advice for everyone in our community is to research our project and wait for an exchange to list our token (note: OTC peer-to-peer trading has many risks and we do not recommend it!). Unfortunately, we cannot disclose anything regarding the exchanges because we have signed non-disclosure agreements with some of them and simply mentioning the name will adversely impact the listing process. We are in contact with multiple exchanges and some are struggling with API integration and some feel uncomfortable with our platform structure because some fear BOScoin to be categorized as "security" - viewing BOScoin to be an investment tool which was explicitly stated that it is not in the Terms & Conditions of the fundraiser, but serves as a utility for the growth and development of the eco-system. We are working around the clock to resolve this issue.

    It's important to know about blockchain technology in order to understand how our project will create real sustainable value. We have a well thought out plan for the BOSnet platform, and a long term development road map which goes beyond just the BOSnet platform, but also developing many business and technology use cases that go beyond just a smart contract platform. We are working every day to make this a reality.

    We are focused on meeting the goals of the project as outlined in the BOScoin White Paper -, with past updates to the development road map published on There will be development updates in the near future.

    We are in the midst of a technological revolution, and there are some who are not capable of understanding, appreciating, or handling the ups and downs of being a part of a project such as ours, and that is ok. Know your limits, and please don't broadcast your anxiety or fears on our community. There are many solid members of our community, who understand our long term vision and that it does in fact take time to build a new blockchain platform. Thank you for your support in our vision.

    Users who spam, by posting over and over again, their illogical fears, and anxieties will be moderated for the overall health of our community. We do not censor criticism, but personal attacks against members of the team or community will not be tolerated. The community plays a part in moderating both the slack and the forum, and on the forum users can flag other user posts for review.

  • BOScoin Newsletter - KuCoin Listing, AMA Video

    KuCoin Listing

    The community pushed hard for BOScoin to be listed on KuCoin and we won the vote by a fair margin last December. It has been a month since the end of the vote now, and although it is frustrating to have been waiting for so long, the KuCoin team is working really hard to get BOScoin listed and we are giving 100% support to make it happen as soon as possible. As you know, BOScoin is based on Stellar, and we are the first Stellar based token to be listed on KuCoin but they have confirmed that they will list BOScoin as soon as all technical issues are resolved. We have been communicating closely and are confident it will happen in a few days. 


    AMA Video

    We would like to thank the community for the questions for the AMA video. There were some good questions and CTO Yezune Choi will appear on the video and address your queries regarding development. Since Yezune's limited use of English, please give us a few days to add subtitles. 

    From now on, we will do more videos instead of texts, and plan to release a video by a member of the team every so often so that you can have a clear grasp on where we are headed and up the marketing effort. This will include updates, lectures, podcasts and interviews. A live Q&A session is definitely in mind but unfortunately not all of us can communicate in English with a sufficient level but it will come at a later stage. Yezune especially has been eager to learn and practice English so that he can give a speech without somebody translating.

    The AMA videos conducted by CTO Yezune Choi, can be found at the following link. The AMA transcript can be found the following links and

    The CTO will do a video once a month to address questions, and update the community on our progress. We think it’s important to have the community’s voice heard and everyone should ask their questions in the forum. Below is the published roadmap for your review.

    As you can see from the above development timeline, BOSnet launch is scheduled for May with the public testNet projected to be released in March. The BOSnet code base will be open sourced at testNet launch. Instructions and tutorials on how to install the BOSnet node client will be published at testNet, and a video will be produced walking you through its installation once the node client is released. As the CTO said, we will support MacOS and Linux, and the minimum specs for the node will be released at testNet. The node client can be ran on a local machine, or on a cloud service of your choosing.

    Consensus and Trust Contracts Specifications

    A lot of work was put into the creation of the specification of the Consensus Algorithm and Trust Contracts, although this may sound trivial, we’d like to stress that we are not just a project that will copy blockchain code, refine it and release it — we are building a completely new blockchain platform from the ground up. Understanding that there would be some that would think “You’re really just tweaking Stellar” — we’d like to advise that we are using Stellar’s consensus algorithm as a basis for our mFBA. This means revisiting the concept behind it, optimizing it based on theoretical research, process and operational analysis, tests, and fit to our environment — and this is only the consensus component — we will need to integrate this into the wider BOS Platform!

    As mentioned last week, we have broken up the development of the Platform into Iterations, these Iterations will specifically focus on the Consensus and Trust Contract components.

    Last Friday marked the last day of Iteration 4, and below is a summary of the outcomes:


    The objective of the consensus component is to determine the ultimate quorum configuration for our Platform.

    The development team created a model able to determine whether the quorum configuration of our network is healthy or not in relation to consensus verification. This required interrogation into the fundamentals of Federated Byzantine Algorithm in relation to safety, liveliness and fault tolerance, then translating that into the model.

    We are happy with how the model satisfies safety and liveliness, but we wish to further explore fault tolerance of nodes and the network — this will be one of our focuses for the next iteration. In addition for the next Iteration, we will:

    • Further our model with fault tolerance and safety verification (what is the difference between Safety and safety verification?)
    • Explore other consensus algorithms in the view of optimizing our BOS Platform (ongoing)
    • Investigate consensus with:
    • Multiple ballots
    • Single client — messages to one node
    • Multiple clients — messages to multiple nodes
    • Message scheduling

    Trust Contract

    This iteration of the Trust Contract stream of work focused on the architecture design and integration components into the blockchain such as the Message, Account, Consensus and Storage objects.

    Next iteration will focus on setting up the environment for the team to further work to write the Contracts — and in the future we will incorporate OWL and TAL aspects to develop the Trust Contract.

    To read more about our Trust Contracts, please visit our Medium articles: Trust Contract Part 1, Part 2, Part 3


    Platform Specifications

    The specifications work the team are working on breaks down the Consensus and Trust Contracts into specific elements. The level that it dives into will essentially map out all the coding required for those aspects.

    As mentioned before, we are keeping development behind closed doors, but we will give you a sneak peek into the work:

    This is just a excerpt of the the specification work which includes elements such as:

    Hash Key & Signature; Multi-sig; Inflation; Node State; Confirmations; Acceptance; Quorum Banning; Validation; Public Membership.

    Meet the Team

    The past week, we had a team attend various events in the US, including the Bitcoin, Ethereum, Blockchain Conference in Dallas; a Dallas BOScoin Meetup; a San Francisco BOScoin Meetup; and a meeting with Franz Inc.


    Dallas: The Bitcoin, Ethereum, Blockchain Conference

    There were many chances for the community to hear and discuss about the BOS Platform with a an estimated 400–500 attendees approaching our BOScoin booth, and our visionary CTO Yezune Choi presenting at a session in the evening of the first day!

    Of the many good conversations we had with the community, a lot of interest was focused on our Public Financing element of the Platform — Public Financing is a alternative way to seek funding for your project, instead of conducting your own ICO, or going down the Venture Capital or Investment Banking channel. our platform will use Trust Contracts to run this to try and transform people towards a Programmable Economy.

    Dallas & San Francisco BOScoin Meetups

    Both the Dallas and San Francisco BOScoin Meetups were held in similar fashion where we ran these in collaboration with our business partner Finger (HYPERLINK:

    Finger is a solid company with years of experience in financial IT and is looking to set up a P2P Exchange where BOScoin will be the first on it when released.

    At the meetup both BOScoin and Finger presented our products, San Francisco were also fortunate enough to hear us provide a brief overview of blockchain technology and Bitcoin; the session was interactive overall with casual questions in between talks.

    At all the events, we were happy to receive so much interest in our Public Financing component of the Platform, where we were even engaged with the community 40mins post the event in some cases answering questions on the very topic!

    We will be uploading videos from the conference and meetup sessions on our official Youtube Channel and website.

  • BOS Newsletter; April 2nd, 2018 - ISAAC — a New Turn!, White Paper, Wallet & More

    ISAAC — a New Turn!

    Last week, our team released the part one of our ISAAC proof-of-concept to the public! This includes an informational webpage detailing the background of ISAAC and also code released on Github.

    ISAAC is abbreviated from Initial, Sign, Accept and All Confirm. These are all states of the consensus process for our consensus algorithm leading to BOSNet; in addition, our CTO decided to show his marketing flair mixing his respect for the renown physicist Isaac Newton combining with the BOScoin product development.

    ISAAC is our test environment for the consensus protocol, which showcases our current progress of the work to the public.It differs from our TokenNet consensus algorithm by including key functionality supporting our BOSNet including Open Membership, performance optimization components. Performance-wise, this includes managing the quorum configuration to ensure safety (consensus validity), and fault tolerance (accommodation for faulty nodes).

    As mentioned, ISAAC is our prototype leading to the final mFBA consensus protocol. Using ISAAC, we will be able to interrogate and test the our concept of the consensus algorithm.

    The Part One release describes our basic concept of ISAAC, including code for the technically interested to play with the protocol.

    Part Two of our release will provide more information to the public in detail including the different configurations to showcase how proper operation of the consensus protocol looks like, and how misbehavior looks like; and how the public can also participate in the testing of ISAAC.

    Once we have conducted all testing of ISAAC, we will need to optimize the consensus algorithm and create the integration with BOSNet functions such as transactions and accounts; congress voting and Trust Contract processing — whereby then, we would have achieved our mFBA.

    White Paper

    Respecting our initial target to have the white paper ready by the end of March, we apologize to the community for not meeting this schedule.

    Our current status for this work is that the first draft is complete is going through reviews — As this version includes much lengthier and detailed information, unfortunately this translates to a longer review time required.

    Below are the steps for us to achieve the final White Paper v2.0 to be released to the public:

    • Closing of the first internal review
    • Amendments to the first draft based on the review
    • First formal review by professionals (including members from renown universities, professors and professionals)
    • Amendments to the white paper based on formal review
    • Final review
    • Final changes
    • Release of white paper 2.0 to the public

    We apologize once again fort he delay, but would like to re-affirm that this does will not affect heavily on the product development, as we are working in parallel on these major work packages.


    March saw a slightly more quiet moment with no BOScoin meetups. However rest assured, we do appreciate our community and support you have for our product and we wish to reinvigorate with the community the next month!

    This time we are focusing on some events in Europe — please see the list below on when and where we aim to be — and if you have a chance, please feel free to drop by at any of the suitable events for a chat!

    Please also note, our Community Manager Scott Matheina holds monthly BOScoin sessions in Dallas — with the next one scheduled for April 18th, 2018 — this session will focus on our ISAAC consensus for those interested.

    Wallet — Keep Walking..

    Our development of the wallet has been progressing behind the scenes and last Friday, our Applications Development Team provided a walk-through of our wallet design, including the flow and image prototypes.

    This release of the wallet aims to improve on the security and user freindliness from public feedback and internal discussions on our web wallet.

    Some optimizations being addressed are including:

    - an address book

    - a Restore Key for better account management including the ability to re-access your account if you lose your secret seed, and also to further protect your account

    The session was successful in a healthy discussion on the security components, cross-checking processes and ideas of the wallet, and discussing the integration of the wallet into the BOScoin environment. The fruitful feedback from our internal review will help us further update the development of our wallet.

    As a sneak peak of the work, we have included a few screenshots of what was presented below!

    Eyes at ISAAC

    If you have not seen yet, our team released the second part to the ISAAC release at the end of last week!

    The second release showcases to the community our development of the BOS consensus protocol.

    Although this release has a slightly more technical tone to it, it essentially illustrates our current progress, interrogating the theory with different scenarios.

    We wish to reiterate our dedication to developing a robust consensus protocol to support the BOS environment.

    When you feel how depressingly slowly you climb it’s well to remember that Things Take Time.”  ― Piet Hein

    Sharing is caring

    Ongoing research to build our BOS platform requires countless reading of documentation, theories, and developments. In doing so, our Dev team have translated various academic papers (unfortunately into Korean only).

    In line with our philosophy of spreading blockchain knowledge to the world, we decided to share these translations with the community via our homepage.

    Although to the global community, this might not mean much, but we hope it further demonstrates our dedication to creating a robust platform; the journey of our trail of thoughts, tasks, and ideas, to implement the BOS platform.

    Waddup Wallet!

    Wallet work is ongoing and our team have released the first prototype of our mobile wallet for internal testing.

    The prototype currently performs the following functions:

    - Create Wallet

    - Import Wallet

    - Send Transaction

    We aim to finalized our internal testing and release the source code soon to the public via Github — please keep an eye out for it!


    Along with platform and applications development, we are also continuously looking to improve our work in other areas as well — Communications management is an area we have most recently focused on.

    We understand the difficulty it has been to find information on BOScoin, as previously our communications were managed via different forums, and not completely synchronized.

    Last week we had our Service Design team presenting the communications refresh to have our website as the single point of reference for official BOS information, whereby our other official channels would follow from that.

    In addition, we aim to populate our website with a more complete set of BOS information including updated FAQs, Development page, refreshed About Us page to name a few.

    We hope yoy see this a a step in the right direction and appreciate your patience in the mean time.

    Have you eaten yet?

    In Korean, it translates as “밥먹었어?” — which is a form of greeting.

    Our meetups provide the opportunity for the interested community to say ’hi’ to our team.

    At our upcoming meetups, members of our team including our community manager and CTO will be available to answer questions in order for our community to learn more about our project, and understand how we fit into the broader market. The following are our upcoming planned meetups for those in the neighborhood:

    Plano, Texas, United States BOS Meetup on TOMORROW (Wednesday) April 18th at 4:00 PM. Register here!

    Amsterdam, Netherlands BOS Meetup on Sunday May 13th at 1:30 PM. Register here!

    Prague, Czech Republic BOS Meetup on Thursday May 17th at 6:00 PM. Register here!

    If any of the above times do not suit, our team members are also attending the Blockchain & Bitcoin Conference on May 17th in Prague, if you are at the event please keep an eye out for our team!

    Distributed Development; Parallel Progress (HINT: Testnet)

    Our development team has split! the development into parallel pieces of work! Below provides an overview of how this all connects.

    Consensus Algorithm

    This relates to ISAAC and the maturing of this protocol for incorporation into our final BOSnet.

    The consensus algorithm, when finalized, will be the modified Federated Byzantine Algorithm, using the consensus by BOS’ quorum structure and rules to achieve the balance of safety, liveness and fault tolerance for our ecosystem.

    Trust Contract

    This is the BOS version of the smart contract, the difference is that, as previously mentioned in an article, Trust Contracts will be built to be decidable using a Timed Automata theory approach. Work has been ongoing to understand how to structure this element, in terms of data and and workflow.

    Foundational Protocol — HINT: TestNet Date

    As Tokennet was released in October last year using the Stellar Protocol, our team here are working on a release to use the stellar concept, but our development coding.

    Estimates are that this work should have a prototype for testing, aka TestNet, targeted for June this year.

    What this will enable is an easier integration when we have all the elements for BOSnet ready.

    We understand that there have been talks about different dates on when TestNet is, or was — and we apologize for the delay. Part of our communications alignment work will be to ensure a single message.

    Sauce me up

    Current work on the mobile Tokennet App Wallet is progressing, with the source code for our first prototype to be released this Thursday! Please keep an eye out for it!

    Counting on Whales

    WhaleX has officially released a countdown on their website to when the exchange will open.

    Good news: WhaleX has advertised that BOS will be among the first listed at open

    Better news: To support the launch, WhaleX are offering 2 events where members can earn BOS via an airdrop and/or a code hunt

    Not so good news: Unfortunately the site and events currently target the Korean community, where to participate, you need a Korean phone number.

    For more information, you may contact WhaleX via their website.
