Workflow

1. Start nodes and chain

• There are multiple nodes that run the same chain
• Chain is started with a genesis block

1. Submit transactions

• User submit a transaction to a node
• Node will validate the transaction
• Node will put the transaction in mempool
• Node will broadcast the transaction to other nodes and wait for package

1. Mine block

• Miner node will package transactions in mempool into a block
• Miner node will evaluate the PoW util finding a valid block
• Miner node will broadcast the block to other nodes
• Other node will validate the block and add it to the chain
