Summary
Threshold Network propose launching tBTC market on Ethereum network.
General
Token Asset Name
tBTC
Project and Token Description
Background tBTC:
tBTC is a decentralized wrapped Bitcoin that is 1:1 backed by native 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 native 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 supported blockchains. As with other BTC wrappers, tBTC provides cryptocurrency traders and general users with a BTC-pegged token, that can be used to generate yield whilst holding native BTC.
- Since launching the full 2-way BTC bridge in August, tBTC has scaled to 9 chains beyond Bitcoin.
- tBTC is the only fully permissionless BTC bridge.
- MCAP increased from 85m to 225m in 3 months.
- Collateral for crvUSD.
- About to go live on Aave.
- Becoming the go-to bridged Bitcoin on Bitcoin L2’s with 706 BTC on Mezo and 229 BTC on BOB, with more partnerships incoming.
Background Threshold Network:
tBTC was created by a decentralized effort of contributors at the Threshold Network DAO, and extensively utilizes the Threshold Network’s threshold cryptography to create a secure BTC asset. tBTC is a product launched on Threshold Network, on which many other decentralized applications such as Threshold Access Control (TACo) and Threshold USD (thUSD) are built.
Threshold Network DAO was born out of the first on-chain merger between two decentralized protocols, Keep Network and NuCypher early in 2022. The DAO has successfully operated since that time, and supports an active community of contributors that work towards building tBTC liquidity and usability.
Benefits to Compound Community
- Further decentralization and trust minimization in the Compound stack.
- A range of lending options for those who wish to earn yield on their Bitcoin.
- Collaboration with the Threshold Network DAO, opening up co-marketing opportunities to boost Compound’s reach.
- Potentially enables direct deposits from BTC chain in the future.
- Preferable yields on tBTC through active incentive participation, boosting Compound protocol use, fees and TVL.
- Threshold Network has internally granted a 45k incentives budget to be distributed over a 3-month period.
- A long-term incentives partnership TBC, depending on the success of this initial distribution.
