Analyzing Mining Pool Behavior to Address Bitcoin Core’s Double Coinbase Reservation Issue
Written by Sadiq Ismail In theory, Bitcoin Core’s block-building algorithm reserves 4,000 WU for miners’ coinbase transactions. This means it should generate a block template with a weight of 3,996,000 WU. However, in practice, this is not the case due to an accidental double-reservation bug (see

Initial Peer Discovery in Bitcoin
Written by Aurelia Naiyoma In the Bitcoin Network, peer discovery is an essential process that ensures nodes can effectively connect and exchange information. This plays a critical role in securing the network by ensuring blocks are propagated and transactions can be validated, forming the core basis of how the network
