    Ready for Merge Ep. 16 👾

    Meet “Floppy”, a full-time Bitcoin developer working on a decentralized privacy solution for Bitcoin called Joinstr.  To unlock greater usability and resilience for Joinstr and other Bitcoin privacy solutions, Floppy has been championing Bitcoin Improvement Proposal (BIP) 119, OP_CTV.  OP_CTV is a proposed opcode that would enable more expressive spending conditions on bitcoin. Though Floppy is not the original author of BIP 119, he has been spearheading ongoing discussions in the Bitcoin community about the proposal and next steps for its activation.  In my interview with Floppy, we discussed how he first learned about Bitcoin in 2015, his passion for on-chain privacy, and his hopes for OP_CTV activation in 2027.  This interview was recorded on January 16, 2026. Timestamps: (1:24) Joinstr overview (4:44) Joinstr development milestones in 2026 (5:50) How Floppy first learned about Bitcoin (8:26) Why Floppy contributes to Bitcoin (9:27) Why Floppy started the OP_CTV workshops (11:14) OP_CTV overview (17:22) Alternative proposals to OP_CTV (21:42) Paths forward for OP_CTV activation (29:18) The main arguments against OP_CTV (36:33) Rapid-fire questions Links:  - Floppy’s X profile (https://x.com/1440000bytes) - Joinstr donations page (https://donate.joinstr.xyz/)  - BIP-119, OP_CTV (https://github.com/bitcoin/bips/blob/master/bip-0119.mediawiki)  - Discussion on OP_TEMPLATEHASH (https://groups.google.com/g/bitcoindev/c/5wLThgegha4)  - BTC Before Light Issue #00 (https://christinedkim.substack.com/p/issue-00)  - BTC Before Light Issue #05 (https://christinedkim.substack.com/p/issue-05)  - BIP-348, OP_CSFS (https://github.com/bitcoin/bips/blob/master/bip-0348.md) This is a public episode.
