Welcome again, fellow Nxters! The Christmas season is in full swing,
and that means giving and receiving presents. Like the comfort of an old
friend, we present to you the important news from the last week in
order to soothe your curious mind. The ANG has a new director, the NXT

We welcome back our old readers and warmly welcome our new ones. The
cryptosphere is a large, complex, and largely mysterious place for most
people and we at Nxter are changing that. We want our readers to become
experts in the blockchain community so you can make informed decisions
and impress your coworkers at the upcoming Holiday parties. Lean back
and learn about the important crypto news from last week!
How Ethereum Classic Light Clients Can SECURELY Operate
Ethereum Classic (ETC) light clients are clients that do not maintain a copy of
the entire ETC blockchain. I will explain how they can nevertheless securely
Light clients obtain blockchain information by communicating with network nodes.
It is possible that malicious network nodes may censor blocks on the longest
chain. Light clients can still operate securely as long as they connect to at
least one honest and up to date node. It is not sufficient to connect to an
honest node. The honest node must itself be connected to another honest node,
and so on. Otherwise, honest nodes may not have all the blocks on the longest
Here is a list of honest ETC network node TCP sockets that light clients can
connect to. (This list can also be found
Hashes are fixed length strings that can guarantee the integrity of all
information. Merkle trees are trees of hashes that can minimize the necessary
communication between network nodes and light clients. The tops of Merkle trees
are referred to as root hashes. Block headers contain the root hashes for light
clients to securely and efficiently obtain state and transaction information
from network nodes. Because block headers are much smaller than entire blocks,
light clients with limited storage can still operate securely by storing just
the block headers of the blockchain.
To be sure a light client is connected to the ETC network, confirm the first
block (genesis block) of the blockchain is associated with the following hash:
This block is where the ETC blockchain diverges from the Ethereum (ETH)
Some think the need for light clients to request state and transaction
information from network nodes might be a vulnerability. The concern is that
network nodes may not always have sufficient incentives to assist light clients.
Some have suggested compensating network nodes for assisting light clients. At
the very least, supporters of ETC are motivated to support light clients to grow
the number of users. Also, smart contract application providers are motivated to
support light clients to increase the number of potential customers.
It is amazing that a protocol exists for even tiny embedded devices to securely
utilize the ETC system. By connecting to honest nodes, only storing block
headers, and, utilizing the properties of hashes, even toasters can benefit from
the ETC world computer.

Cryptospace 2017 in Moscow! Vinchain Team Successful Results
Now as you may already know, Cryptospace conference is one of the largest platforms that support blockchain technology and cryptocurrencies. Every year, they host approximately 30,000 participants from 30 countries. This year’s event took place on 8th December and we were part of the participants. Last Friday, we had such a great time at the conference in Moscow.
It all started early in the morning and lasted till late in the evening. We met so many experienced people who were interested in our idea. What’s more, investors are really interested to be a part of our project after the presentation. We showed them how to take part in the presale by signing up in our website. During the whole conference, our stand was never empty. We had so many people come to talk to us throughout the day. We did not hesitate to answer the questions while telling them about our project and what we are going to do. We were extremely happy about such a great feedback that we had during this day. So many people told us that they are interested in what we are doing and that they found our idea highly perspective. We also exchanged contacts and are looking forward to communicate with our future partners and investors.
