Long Island Blockchain Meetup Begins

The Long Island Blockchain meetup group is officially created and begins heating up amongst the local developer community.

September 2017

Website launch

The 1st official website for the Long Island Blockchain organization is launched featuring a blog, news, and forum for all community members to share all things related to blockchain technology and cryptocurrency.

October 2018

Virtual Conference Meetup

On October 19th, 2018, we launched a new virtual conference series of meetups. The primary topic of this conference was framed around identity on the blockchain.

November 2018

Local Expansion

As our organization continued to build up steam, Long Island Blockchain quickly became a hot topic of discussion amongst the local business community. As such, we decided to establish our official office within a local tech incubator called LaunchPad Huntington lead by Phil Rugile.

Frequently Asked Questions

A blockchain, originally block chain, is a continuously growing list of records, called blocks, which are linked and secured using cryptography. Each block typically contains a hash pointer as a link to a previous block, a timestamp and transaction data. By design, blockchains are inherently resistant to modification of the data. It is “an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way”. For use as a distributed ledger, a blockchain is typically managed by a peer-to-peer network collectively adhering to a protocol for validating new blocks. Once recorded, the data in any given block cannot be altered retroactively without the alteration of all subsequent blocks, which requires collusion of the network majority.

Blocks hold batches of valid transactions that are hashed and encoded into a Merkle tree. Each block includes the hash of the prior block in the blockchain, linking the two. The linked blocks form a chain. This iterative process confirms the integrity of the previous block, all the way back to the original genesis block.

A hard fork term refers to a situation when a blockchain splits into two separate chains in consequence of the use of two distinct sets of rules trying to govern the system. For example, Ethereum has hard-forked to “make whole” the investors in The DAO, which had been hacked by exploiting a vulnerability in its code. In 2014 the Nxt community was asked to consider a hard fork that would have led to a rollback of the blockchain records to mitigate the effects of a theft of 50 million NXT from a major cryptocurrency exchange. The hard fork proposal was rejected, and some of the funds were recovered after negotiations and ransom payment.
