Blockchain is an emerging way for businesses, industries, and public organizations to almost instantaneously make and verify transactions -- streamlining business processes, saving money, and reducing the potential for fraud. At its core, a blockchain is a data structure that's used to create a digital transaction ledger that, instead of resting with a single provider, is shared among a distributed network of computers.
The result is a more open, transparent, and publically verifiable system that will fundamentally change the way we think about exchanging value and assets, enforcing contracts, and sharing data across industries. The applications using blockchain are almost limitless, ranging from loans, bonds, and payments to more efficient supply chains to even identity management and verification.
The main difference between blockchain identities and accounts on any other service is that blockchain-based systems have strong ownership. Blockchain identities can't be confiscated by any service because the system defines ownership according to ownership of public-private keypairs, just like ownership of coins on Bitcoin. This is in direct contrast to Twitter or Facebook usernames, which could be confiscated or censored at any time by the respective companies that they belong to.
The BlockChain Identity EcoSystem is based on the Autonomous Decentralized Peer-to-Peer Telemetry (ADEPT) system & also levereges the the Directed Acyclic Graph (DAG) chain. This provides a truly distributed peer-to-peer network with Smart-Contracts distributed across multiple blockchains.
