tBTCThreshold details tBTC FROST Schnorr migration; signer set stays 51-of-100
Threshold Network laid out tBTC's Q4 roadmap, centered on migrating the bridge from ECDSA (GG18) to FROST Schnorr multisignatures to tighten security, reduce bridge latency, and speed up mint and redemption processing.
Follow-up posts on Threshold's X account (Oct 19, 2026) confirmed the switch to Schnorr keeps the 51-of-100 signer set unchanged while opening the door for further expansion of the signer set and bridge capabilities. The roadmap was originally announced Oct 5, 2026 with a short video; additional Q4 items beyond the FROST migration are still being detailed.

tBTC
tBTC is a decentralized wrapped Bitcoin that is 1:1 backed by main-net BTC. Unlike other wrapped Bitcoins, the BTC that backs tBTC is not held by a central intermediary, but is instead held by a decentralized network of nodes using threshold cryptography.
tBTC is trust minimized and redeemable for main-net BTC without a centralized custodian. It can be used across the entire DeFi ecosystem.
tBTC can be used as collateral, liquidity, a store of value, and can be integrated with DeFi apps across all blockchains.
As with other BTC wrappers, tBTC provides cryptocurrency traders and general users with a non-volatile BTC token, that can be used to generate yield whilst holding main-net BTC.
