09/05/2017 · The Bitcoin blockchain in its simplest form is a database or ledger comprised of Bitcoin transaction records. However, because this database is distributed across a peer-to-peer network and is without a central authority, network participants must agree on the validity of transactions before they can be recorded. This agreement, which is known as “consensus,” is achieved through a process.

Blockchain Consensus algorithms ensure each new block added to the network is the only version of the truth, which is agreed by all the nodes.
That's what makes it part of a chain, hence the term “blockchain.

31/01/2016 · An academic lecture by Andreas M. Antonopoulos explaining the consensus algorithm, "Proof of Work", used by bitcoin and many other blockchains. Andreas is a UCL alum. This talk was presented in.
A consensus algorithm is a mechanism that allows users or machines to coordinate in a distributed setting. It needs to ensure that all agents in the system can agree on a single source of truth, even if some agents fail. In other words, the system must be fault-tolerant (see also: Byzantine Fault Tolerance Explained).

I ask the second question because the bitcoin system use some mechanisms to make all the miners share the same block chain. I'm new to this field and it seems that ZooKeeper and Paxos are used for solving consensus and coordination problem in the distributed application, and I am curious about how does bitcoin system solve that problem 🙂 – Ting Mar 7 '14 at 13:44
