BIP 119 CTV activation client

# · /dev/fd0 · #1 · 09 Feb 2026, 20:22 UTC

Since there were no objections to the activation parameters shared in the last email, I have updated the website with the repository link for activation client and added some FAQs.

Repository: GitHub - ctv-activation/activation-client

// Deployment of CTV (BIP-119)
consensus.vDeployments[Consensus::DEPLOYMENT_CTV].bit = 5;
consensus.vDeployments[Consensus::DEPLOYMENT_CTV].nStartTime = 1774809000; // 30 March 2026
consensus.vDeployments[Consensus::DEPLOYMENT_CTV].nTimeout = 1806345000; // 30 March 2027
consensus.vDeployments[Consensus::DEPLOYMENT_CTV].min_activation_height = 1001952; // May 2027
consensus.vDeployments[Consensus::DEPLOYMENT_CTV].threshold = 1815; // 90%
consensus.vDeployments[Consensus::DEPLOYMENT_CTV].period = 2016;

Sorry, just say this in a search engine query. I think a next year activation is not in line with the current vibe that I get from the larger Bitcoin community who seems skeptical of CTV still. We need to demonstrate in software the use cases. Particularly, things like demonstrating how CTV helps in high fee environments will be the most high value demonstrations that average users can test on their own machines.

I am admittedly, way far behind where I need to be to create such software, however

A useful demo should make the comparison reproducible, not just show a CTV transaction working. For a high-fee scenario, publish the exact setup and compare the on-chain weight and fee against the best non-CTV construction for the same outcome, including any setup or recovery transactions. That would address whether CTV changes the economics for users, rather than only illustrating that the opcode can express the construction. Also, no objections to parameters on one mailing-list thread doesn’t establish community readiness.
