Blockchain
In short, blockchain is a immutable linked list of hashes. Which can be used to solve the double spending problem in cryptocurrencies using proof of stake (or other methods) and a persistent chain of records (blocks mined).

Consensus algorithms

  • PoW: The more hashing power the more trust worthy.
  • PoS: The more coins the more trust worthy.
  • PBFT: Hand selected trusted nodes.
  • Randomized asynchronous algorithm: You trust nobody! Every single node is constantly re-evaluated. (Skycoin)
