A blockchain is a chain of blocks.
Do you have another definition?
Colloquially, it often refers to a consensus algorithm paired with a chain of blocks.
Bitcoin’s innovation wasn’t a blockchain, it was a proof-of-work backed consensus algorithm that allowed a group of adversarial peers to agree on the state of a shared blockchain datastructure.
- waterheater 3y agoAccording to the dictionary [1], a blockchain is "a digital database containing information (such as records of financial transactions) that can be simultaneously used and shared within a large decentralized, publicly accessible network" The distinction here might be with a decentralized network.

- pests 3y agoEvery word in that definition seems to fit, no?
- tidenly 3y ago"decentralized" isnt necessary to a block chain. However when people say "block chain" in everyday use, they're usually talking about that type. It's a case where the everyday use of a word is different to the actual technical meaning.
- pests 3y ago> It's a case where the everyday use of a word is different to the actual technical meaning. Which can change. There also is centralized proof-of-work blockchains. Clouds were offering them awhile back and IBM had some offering.
- pests 3y agoA blockchain used to be a chain of blocks. It's more now. You kinda defined it - consensus algoithm, shared datastructure. What is colloquially even susposed to mean here? That the common usage doesn't match the definition? Maybe definitions change over time....
- kortilla 3y agoSo a linked list is a blockchain?
- r3trohack3r 3y agoIf you have a chained hash of the data in the linked list, yes!
