=== Assembling and Selecting Chains of Blocks
((("mining and consensus", "assembling and slecting chains of blocks", id="MACassembling10")))((("blocks", "assembling and selecting chains of", id="Bassemble10")))The final step in bitcoin's decentralized consensus mechanism is the assembly of blocks into chains and the selection of the chain with the most Proof-of-Work. Once a node has validated a new block, it will then attempt to assemble a chain by connecting the block to the existing blockchain.
((("mining and consensus", "assembling and selecting chains of blocks", id="MACassembling10")))((("blocks", "assembling and selecting chains of", id="Bassemble10")))The final step in bitcoin's decentralized consensus mechanism is the assembly of blocks into chains and the selection of the chain with the most Proof-of-Work. Once a node has validated a new block, it will then attempt to assemble a chain by connecting the block to the existing blockchain.
Nodes maintain three sets of blocks: those connected to the main blockchain, those that form branches off the main blockchain (secondary chains), and finally, blocks that do not have a known parent in the known chains (orphans). Invalid blocks are rejected as soon as any one of the validation criteria fails and are therefore not included in any chain.
