Bitcoin Has a Spam Problem. BIP-110 is the Fix. Right now, Bitcoin’s block space is being used for things that have nothing to do with money: Ordinal inscriptions: JPEGs and HTML blobs stuffed into witness data BRC-20 / Runes — meme coin token ($dog) protocols riding OP_RETURN Stamps / SRC-20 — data encoded in bare multisig, permanently bloating the UTXO set Citrea ZK proofs — a VC-backed sidechain using Bitcoin mainnet as its data availability layer to back a KYC’d USD stablecoin Counterparty, Atomicals, and every meta-protocol that treats Bitcoin as a cheap hard drive Bitcoin Core v30 made this worse by removing the OP_RETURN size cap entirely — an open data pipe, ratified by the dominant implementation. BIP-110 changes the game in two phases. Today, nodes running Bitcoin Knots with BIP-110 refuse to relay these transactions. It narrows the mempool path for spam and signals that the network does not want this. But when BIP-110 activates as a soft fork, these aren’t just discouraged. they’re invalid. A block containing an inscription or a Citrea ZK proof gets orphaned. No rational miner loses a block reward to include spam. The spam dies at the consensus layer. This is how Bitcoin defends itself. Not by asking nicely. By making itself hostile infrastructure for everything that isn’t sound money. Run a node. Run Knots. Signal the soft fork. Euthanize the $Dog 📝 9df1c76a…
