Broadcast Transaction:\nWhen a user adds a new transaction, the central server broadcasts it to all connected miners.\n\n2. Manage Transaction Pool:\nThe server adds the transaction to its own transaction pool and removes transactions that are already included in a mined block.\n\n3. Broadcast New Transactions:\nThe server keeps miners updated by broadcasting new transactions regularly.\n\n4. Verify and Add Block:\nOnce a block is mined by any miner, the central server verifies it and broadcasts the new block to the rest of the miners.\n\n5. Adjust Difficulty:\nAfter receiving each new block, the server adjusts the difficulty level to maintain a steady block time.\n\n## Miner Server Responsibilities:\n1. Receive Transactions:\nEach miner receives new transactions from the central server and maintains its own transaction pool.\n\n2. Mine Blocks:\nMiners mine blocks at a fixed interval by performing Proof of Work (PoW). This involves finding a valid hash based on the difficulty level.\n\n3. Broadcast Mined Block:\nAfter successfully mining a block, the miner broadcasts it to the central server, which further distributes it to all other miners.\n\n4. Verify Block:\nEach miner verifies the received block and checks if the chain is valid. Smaller or erroneous chains are rejected.\n\n5. Update Blockchain:\nThe miner updates its local copy of the blockchain and adjusts the mining difficulty based on the central server’s broadcast.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpratik-codes%2Fgo-blockchain","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fpratik-codes%2Fgo-blockchain","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpratik-codes%2Fgo-blockchain/lists"}
