BCDiploma - Blockchain Certified Data - Certified Diploma on Ethereum



  • The ultimate goal of BCDiploma is to certify diplomas in the simplest, most secure, and sustainable way possible, by associating Ethereum technology with a high level of cryptography. As EdTech experts and higher education specialists, we know the expectations of schools in this domain. Facing the falsification of their diplomas and an increased competition, they are ready to offer their graduates an innovative digital service to protect their image. 

    BCDiploma develops a DApp for institutions of higher education to enable them to issue their degrees on Ethereum. BCDiploma allows the graduate, throughout his life, to prove the authenticity of his diploma by providing a simple URL. It is a competitive solution, durable, unfalsifiable, compatible with social networks, simple to use, perfectly adapted to the uses of higher education. Schools have not yet adapted a certification standard? We offer it to them. Once put in production for schools, what future for BCDiploma, solution developed by Blockchain Certified Data (BCD)? BCD will have an inexpensive, fast-running open source ecosystem created, in order to deploy on-chain registries while respecting the right of personal data on Ethereum. 

    These on-chain registers are usable by all on a daily basis: they read a smart-contract certified data. It’s a general application of Ethereum: each and everyone of us can prove in a single click that he is well qualified, doctor, holder of a driving license... The fields of application are numerous: professional competences or certifications, registers of regulated professions, internal business registers, administrative registers… 

    Ethereum, by its scalability, is technically ready to store registers on a large scale: we want to develop the framework of it and make the use of DApps a daily action for everyone. To accompany us in this project is to make a step towards a world in which we will all trust in the data issued by the institutions.

    Number of degrees issued worldwide

    More than 4 million students graduate every year from higher education throughout the European
    Union[1].
    Almost 4 million college students (Colleges and Universities) graduate in the United States each
    year[2].
    Nearly 7 million university degrees were awarded in China in 2012[3].
    The OECD calculated that its member countries, as well as those of the G20, will bring in total nearly
    204 million graduates aged 25 to 34 in tertiary education in 2020, compared with 129 million in
    2010[4]:
    • China: 29% (about 60 million graduates);
    • India: 12% (about 25 million graduates);
    • United States: 11%;
    • Russian Federation: 7%.
    The LinkedIn social network exceeded the 500 million registered in 2017: a very large majority of
    them have several diplomas on their profiles.

    The fake diploma market

    Have you ever searched “fake diploma” on Google? Just give it a try before you read the following
    paragraph!
    It’s a well-established matter of fact, constantly relayed by the media: the fraudulent use of
    fake diploma, or made-up qualifications on resumes and social media is a hard fact impacting
    schools, graduates and employers. This problem has been addressed in the news many times.

    Yahoo!’s former CEO[5] Scott Thomson, or Melania Trump[6] in the US: scandals are constantly
    emerging.
    “In France, 33% of applicants use fake diploma. This number is similar in the United Kingdom.
    According to the official organism in charge of diploma authentication, (...) 30% of the applicants lie
    about their qualifications.” [7]
    Two markets, the first one being on the edge of the law, the second one being clearly illegal, are
    taking advantage of this trend:
    • Diploma mills / degree mills selling real diploma from schools that don’t exist, or having a more
    than thin physical reality[8];
    • Professional websites selling high quality replica diploma.
    In order to counter the phenomenon, societies have popped up to “verify” degrees afterwards and
    check their authenticity: Verifdiploma or RiskAdvisory are some examples of this.

    OUR VISION IS TO CREATE A NEW STANDARD TO ACCESS CERTIFIED PERSONAL AND ACADEMIC DATA

    The topic of diploma certification is very old in the world of blockchain (the
    experiments of ESILV, Holberton School or MIT must be mentioned). But
    with the arrival of Ethereum, the game has changed, and, with BCDiploma,
    we are now able to offer a solution that can be deployed massively in
    establishments all over the world. BCDiploma is the first application case of
    our EvidenZ framework. It is a perfect answer to the question of diplomas
    and will be widely deployed in schools from 2018 onwards through our
    “Incentive” programme.
    But the stakes are higher: EvidenZ allows any company or administration
    to certify data on Ethereum. Diplomas, competences certificates,
    accreditations, regulated occupations, civil status documents, insurance
    certificates, registration documents, scuba diving certificates, etc. EvidenZ
    has the arguments to become the new standard!

    A FAST-INCREASING MARKET

    Malta, Australia, USA: recent experiments are making the idea that the
    blockchain is the right technology to certify diplomas very popular. Big
    stakeholders, such as Sony and IBM, plans to launch their own “proprietary”
    solutions.
    EvidenZ is an innovating technology, compared to the current blockchain
    actors. Easy-to-implement and user-friendly, the framework has been
    conceived for the general public. Our incentive programme is ambitious
    and aims to give to EvidenZ a worldwide exposure, from 2018 onward.

    WHAT’S NEW WITH EVIDENZ?

    All organizations will be able to issue «one click certified» data with a
    simple DApp. All individuals will be able to share certified personal data,
    without having an Ethereum address. EvidenZ is the pionnier in terms of
    implementing the «right to be forgotten» on Ethereum.

    What’s EvidenZ DNA?

    EvidenZ stores neither documents nor their hash fingerprints, but only
    encrypted data directly on Ethereum. EvidenZ generates trust by validating
    the identity of data issuers first. EvidenZ is open source, so that the access
    to data remains limitless through time.

    What’s EvidenZ business model?

    Any entity can use the EvidenZ authentication service. No subscription
    or recurring fee, only issuance has to be paid. The service will be free for
    anyone who consults the data.

    Why is Evidenz secured?

    Only an organism whose identity has been verified can issue data. The
    EvidenZ cryptographic protocol guarantees the control of the access to
    data and the “right to be forgotten”. The data stored by EvidenZ cannot be
    modified or collected, or exploited for commercial purposes.

    Is EvidenZ in compliance with the GDPR?
    European General Data Protection Regulation (GDPR), which will become
    enforceable by in May 25, 2018, is now the new reference text on personal
    data protection, and will become globally applicable. EvidenZ is already
    compliant with this 

    new regulation and invents the “right to be forgotten” on Ethereum.

    WHY BCDT TOKEN?

    BCDT token is the fuel of EvidenZ’s ecosystem. Entities, universities and
    other partners will be required to have tokens to use the service. In order to
    establish the standard, we planned a major incentive programme in 2018:
    20% of the issued tokens will be offered to the most renowned schools in
    the world, in order to certify all their issued diplomas until now.
    When the service is used, 5% of the tokens are burnt. The BCDT token is an
    application token to “reload” the “Number of data to be issued”. As such, it
    has every chance of being placed on a large number of exchanges and not
    being constrained by the securities legislation.

    THE INITIAL TOKEN SALE

    An Initial Token Sale (ITS) is an event in which a project related to cryptocurrency sells a part of
    its tokens to early adopters and enthusiasts in exchange of financial supports. This process of
    crowdfunding is now an acknowledged and standardized mean to obtain funds destined to the
    large-scale development of a product or a service, be it an existing service or a in construction
    service. The necessary funds to launch our BCDiploma application will be raised through a
    Ethereum-based crowdfunding.

    The ecosystem of BCDT’s token

    BCDiploma’s goal is to become the point of reference for diplomas’ certification. Our challenge
    today is to gain schools’ confidence and patronage worldwide, and to expand our services and offer
    them to companies and administrations in the near future. These institutions, public or private,
    might not have “blockchain” knowledge. In the first place, to convince them, we have to offer a
    product fitting their needs perfectly. We also have to be ready to offer a billing system, which is
    easy to use and understand and meets their standards. The right way to encourage schools to use
    Ethereum on a daily basis is to bill them in USD.
    What added value do we propose? The value created by BCD will be measured proportionally to
    the volume of on-chain data issued by the institutions.
    The key-words of the BCDT tokens ecosystem are: trustless and automation.
    The unit cost of issuing a diploma will be measured in BCDT tokens at constant FIAT (USD) prices.
    The BCDT / ETH / USD rate will be updated at regular intervals on the smart contract Smart
    Identification by a decentralized exchange bot to guarantee the issuer this fixed unit price in Fiat
    (USD). To protect the issuer from the variability of the BCDT token, the issuer will “buy”, if he wants
    to, a “Number of diplomas to be issued”, thus limiting transactions in BCDT tokens for users of the
    eco-system. More precisely:

    • For each ID Certificate, the smart contract Smart Identification stores a variable “Number of
    diplomas to be issued”;
    • At the creation of the certificate by Smart Identification smart contract, this variable is initialized
    to 20 (i.e. “20 offered diplomas”), in order to facilitate the adoption of the product;
    • Subsequently, the issuer values the “Number of certificates to be issued” variable of his ID
    Certificate by sending BCDT tokens to the smart contract Smart Identification. At the time of
    this transaction, the issuer knows the unit price in BCDT tokens of a diploma yet to be issued;
    • In the same operation, the smart contract Smart Identification burns the equivalent of 5% of
    BCDT tokens paid for “diplomas to issue”, as a manufacturing fee;
    • When issuing a diploma via the smart contract Smart Publication, the “Number of diplomas to
    be issued” variable is decreased by one.
    The BCDT token is therefore an application token to “reload” the “Number of diplomas to be
    issued” of a school. As such, it has every chance of being placed on a large number of exchanges
    and not being constrained by the securities legislation.

    The Initial Token Sale

    During this ITS, the token we offer will be called “BCDT token”. It is compliant with the ERC-20
    standard.
    Presale will start December 2017. Detailled timing will be available on www.bcdiploma.com.
    During the ITS, the Ethereum (ETH) will be the only accepted currency to buy BCDT tokens.
    The contribution’s address will be unveiled on www.bcdiploma.com.
    BCDT tokens will be available in the investors’ wallet immediately and will be transferable 12 days
    after the end of the ITS. The tokens’ distribution will happen exclusively through BCDT token’s
    smart contract. Its source will be provided.
    If the total amount raised during BCD’s ITS is below the softcap, the investors will get the totality of
    their contribution back. These rules will be fully followed by BCDT’s token smart contract.

    Tokens’ sale: settings

    The following figures might vary based on the USD / ETH exchange rates. They were our best
    estimations on October 6th, 2017.
    The ITS goal is to raise a maximum amount of $12M (approximately 40,000 ETH).
    • Time of the ITS: Presale will start December 2017;
    • Number of tokens for sale: 100,000,000 BCDT tokens;
    • ITS’ maximum sale revenues: $12M (approximately 40,000 ETH);
    • ITS’ minimum sale revenues: $3M (approximately 10,000 ETH);
    • ETH / BCDT’s indicative exchange rate : 1 ETH = 2,500 BCDT tokens.
    Incentive Program: depending on the ITS stage, bonus BCDT tokens will be offered:
    • Presale: 20% bonus, 60 ETH is minimum contribution. $3M limit;
    • First round: 10% bonus. $2M limit;
    • Second round: no bonus;
    • Third round: no bonus.
    Presale and all rounds managed by smartcontract, contributors have to be whitelisted through a
    KYC. More information on www.bcdiploma.com.

    ITS’s completion
    The ITS will end when all the tokens are sold, and, failing that, after the second round is over.
    If, at the end of the ITS, the minimum sale revenues isn’t achieved, the totality of the funds raised
    will be refunded to the BCDT’s buyers.
    If, at the end of the ITS, the minimum sale revenues is reached, then the smart contract of the
    BCDT token will proceed to the issuing of the saved tokens. Those tokens will be allocated to the
    community and to the BCD team, according to the proportions described below.
    The tokens allocated to the BCD founders will be blocked during one year.
    BCD will not create any new BCDT tokens after the BCDT Initial Token Sale.

    Tokens distribution

    Our goal is to guarantee a BCDT token distribution as wide and as fair as possible.
    Based on a token sale of a maximum amount of $12M or 100 million tokens:
    • Initial BCDT tokens’ sale offering: 100 million – only sold tokens will be created. The total
    supply of the issued BCDT tokens will amount to 1.5 times the amount of the sold tokens;
    • BCDT Tokens set aside: 20% of tokens minted;
    • BCDT tokens allocated to community members promoting BCD, including team, excluding
    founders: 10,3% of tokens minted. The allowance will be at BCD’s sole discretion;
    • BCDT tokens allocated to BCD’s founders: 3% of tokens minted.

    How are we going to use the funds ?

    To implement BCD’s strategy during the first 36 months (see the “strategy” section), we plan to use
    the ITS’ tokens sale revenues as follow:
    • Application’s development: 35% of the revenues generated by the tokens’ sale ;
    • Marketing and Business development: 30% of the revenues generated by the tokens’ sale ;
    • Incentive campaign: 15% of the revenues generated by the token’s sale.
    In 2018, BCD’s goal is to publish, on every continent, the diplomas of the most important schools,
    offering them an incentive program up to the task. This program will be the object of a massive
    marketing campaign toward:
    • The education field players;
    • Graduates;
    • Recruiting field players (LinkedIn, head-hunters, job search tools);
    • Reserve: 10% of the revenues generated by the tokens’ sale will be kept as long-term savings;
    • ITS expense: 5% of the revenues generated by the tokens’ sale will be reserved for ITS advisors
    bounties, workers bounties, legal and IT charges refund;
    • General expense: 5% of the revenues generated by the tokens’ sale. BCD is a lean,
    cost-effective start-up and will continue to be so in the future.

    CRYPTO ALGO APPENDIX

    Technical features
    The encryption algorithm we use, AES – 256 – GCM, is standardized:
    • AES-256: http://nvlpubs.nist.gov/nistpu...
    • GCM mode: http://nvlpubs.nist.gov/nistpu...
    The AES-GCM is often used and is referenced for many security protocols:
    • IPSEC: RFC 4106
    • IKEv2: RFC 5282
    • TLS: RFC 5288
    • CMS: RFC 5084
    • SSH: RFC 5647
    • SRTP: RFC 7714
    The AES is recommended for usage exceeding 2030 with a 128-bit key. For a 256-bit key, it is among
    the safest standardized cryptography algorithms.
    A standardized derivation algorithm KBKDF (Key-Based Key Derivation Functions) will be used;
    Key sizes:
    • MasterKey and KAES: 256-bit AES keys;
    • Nonce: random value of 96-bit;
    • RND: 96 alphanumerical octets base64 encryption of a 576-bit random value.
    For a school, we will create a secured environment (Key store):
    • An AES MasterKey, in a HSM (Hardware Security Module): it will be used to derive the RND
    intermediate keys;
    • A MasterNonce random value;
    • A CtrDerivation derivation meter: updated every issuance;
    • A “persistence keys” table: [IdData, RND1, Nonce, idETH].
