A consensus algorithm may be defined as the mechanism through which a blockchain network reach consensus. Public (decentralized) blockchains are built as distributed systems and, since they do not rely on a central authority, the distributed nodes need to agree on the validity of transactions. This is where consensus algorithms come into play. They assure that the protocol rules are being followed and guarantee that all transactions occur in a trustless way, so the coins are only able to be spent once.


Please write a clear, concise description of your topic here.You will likely reference your introduction from somewhere else. Please use the following syntax at the end of each of your ideas. '''IT IS CRITICAL YOU ATTRIBUTE''' others work. Your introduction should be factual. No more than 3 or 4 sentences, please. Because you are not an expert in your topic, I expect you to triangulate your information. LOTS OF LINK TO OTHER RESOURCES PLEASE! If you do not use a section, please delete it. Your finished page should only have information which explains your topic.

Programming[1]

A distributed consensus ensures a consensus of data among nodes in a distributed system or reaches an agreement on a proposal.[2]

A consensus algorithm may be defined as the mechanism through which a blockchain network reach consensus. Public (decentralized) blockchains are built as distributed systems and, since they do not rely on a central authority, the distributed nodes need to agree on the validity of transactions. This is where consensus algorithms come into play. They assure that the protocol rules are being followed and guarantee that all transactions occur in a trustless way, so the coins are only able to be spent once.
