  12. 12. • Independent verification of each transaction by every full node, based on a comprehensive list of criteria • Independent aggregation of those transactions into new blocks by mining nodes coupled with demonstrated computation through a proof-of-work algorithm • Independent verification of the new blocks by every node and assembly into a chain • Independent selection, by every node, of the chain with the most cumulative computation demonstrated through proof of work (or X) Decentralised Consensus In a Peer-to-Peer Network
  13. 13. What kind of Platforms are we seeing? 1. “Vanilla” Blockchains: Bitcoin and simple altcoins 2. “Application” Blockchains: specific for one use, for instance Gridcoin (BOINC) 3. Complete Platforms with new functionality: Nxt, Ardor, Bitshares 4. “Blockchain Computers”: Ethereum
