Consensus Algorithms

Process work to validate

transactions

Node ....Transactions to be processed Transactions already validated (and in the chain)

NodeNode Node

...

Example of work: find right code to open the lock. Difficult to find the code, easy to verify it.

Algorithm

1. Retrieve group of transactions from pending transactions to be validated

Group to be validated

2. Process work to generate proof (e.g. lock code) 3. Broad cast proof-of-work to all nodes (e.g. code to open the lock)

4. Write transactions into the blockchain if proof-of-work is valid for majority of nodes (e.g. nodes can open the lock)
