In December 2025, a proposal titled BIP-110 (full name: "Reduced Data Temporary Softfork") was submitted to the Bitcoin Improvement Proposals repository. Its goal is straightforward and sharp: at the consensus layer, temporarily restrict arbitrary non-monetary data in transactions, driving "data-storage" applications such as Ordinals inscriptions, BRC-20 tokens, the Runes protocol, and more out of the Bitcoin mainnet. The proposal quickly split the Bitcoin community into two camps, and the intensity of the controversy even surpassed the block size wars of that year.
1. What exactly is BIP-110 trying to do?
The core logic of BIP-110 is simple: Bitcoin block space is a scarce resource. It should primarily serve the original mission of "peer-to-peer electronic cash," rather than becoming a permanent storage hub for NFTs, memes, and tokens.
