Evolution of Distributed Ledger Technology
The following diagram shows how, after the first attempts at decentralization in the 1990’s, the Distributed Ledger Technology has progressed in the last few years, by using crypto-networks’ blockchain technology and different consensus models: Examples and classification The following are examples of blockchain crypto-networks and how their consensus protocols can be categorized, referring to the two key questions in the previous diagram: Who maintains the integrity of the ledger? P: Permissioned: Trusted owners/agents: Ripple-based (a group of actors): Tillit Ripple , Tembusu , Ripple Lab . Decentralized group of trusted agents: Hyperledger , Clearmatics , Eris . Bitcoin-inspired blockchain, oracle-based: MultiChain , Cryptocorp. Flexible, Proof of Stake (PoS): Tezos. Sharding: Disledger. Trusted node-to-node paths: Trustlines . Federated : C...
