Bitcoin Core 29.1 Slashes Default Relay Fees by 90%, Boosting Transaction Affordability

The latest Bitcoin Core 29.1 update has implemented a substantial reduction in default minimum relay fees, cutting the rate from 1 satoshi per virtual byte (sat/vB) to just 0.1 sat/vB. This 90% decrease marks a significant shift aimed at lowering transaction costs across the Bitcoin network while preserving essential denial-of-service (DoS) protections. The adjustment allows node operators to process transactions with far lower fees, enhancing network efficiency and accessibility for users. By reducing the economic barriers for on-chain transactions, the update supports broader adoption and everyday use of Bitcoin. Network participants and node operators are advised to review their fee policies to align with the new defaults. This change reflects ongoing optimizations within Bitcoin’s infrastructure to balance security, scalability, and user experience.
