Episode two of the Bitcoin Node Runner podcast. PerkINsights and BitLovin work through the first of four issues at the center of The Block Size War, the book by Jonathan Bier about the fight over Bitcoin's base layer.
We start with a quick recap of the bridge analogy and the three participants in the Bitcoin protocol: developers as the architects, miners as the builders, and nodes as the inspectors. Then we get into issue one. Should Bitcoin blocks have surplus room in them, or should they stay consistently full?
Both sides of this argument came from people who cared about Bitcoin. One camp saw it as a payments network competing with Visa and wanted bigger blocks to fit more transactions. The other camp wanted to protect decentralization and security at the base layer, even if that meant giving up scalability there.
We also talk about pruned nodes versus full nodes, why scarce block space matters for miner incentives once the block subsidy runs down, and how Moore's law factors into whether everyday people can keep running a node as the blockchain grows.
