CoinList adds the ability to coin tBTC, simplifying the use of Bitcoin in DeFi

 16. Dezember 2020      

Users can now coin tBTC, a decentralized version of Bitcoin in the Ethereum block chain, in the CoinList exchange.

tBTC acts as a Bitcoin (BTC) wrapped in Ethereum, therefore it is compatible with the Ethereum block chain for various purposes, such as decentralized finance (DeFi). Users of tBTC can now coin the asset in the crypto currency exchange, CoinList.

„Large investors and retailers who may not feel very confident using a very new DApp (decentralized application) can go into CoinList and wrap or unwrap tBTC the same way they do with WBTC today,“ Matt Luongo, CEO and founder of Thesis, the entity behind tBTC, told Cointelegraph. Keep is another Thesis project that is involved in tBTC.

As two separate block chains, Bitcoin and Ethereum are not inherently compatible with each other. Ethereum, however, houses much of the activity of the DeFi sector of cryptomontages. Wrapping Bitcoin in the Ethereum block chain allows users to maintain their value in Bitcoin while using it to interact in the DeFi ecosystem. tBTC is a „minimised trust bridge from Bitcoin to Ethereum,“ explained Luongo.

CoinList adding tBTC functionality enhances simplicity for those looking to use the asset. „Although tBTC is censorship-resistant and does not require permission, it is still annoying to use,“ said Luongo. „It’s harder to do anything without a trade-off.

Wrapped Bitcoin (WBTC), an independent asset backed 1-to-1 by stored BTC, has become one of the industry’s most popular options for using Bitcoin on the Ethereum network, although the WBTC model is more centralized, according to Luongo.

„BitGo is the registered custodian, and merchants can basically interact with BitGo to coin and get. But ultimately, what they are doing is getting BitGo to own Bitcoin, and then they are creating a script on Ethereum. So it’s absolutely like a bank of Bitcoin, that would be one of the popular ways of saying it, and it’s been great for DeFi.

Essentially, the entity responsible for the WBTC oversees the minting of the asset, as well as the Bitcoin behind it. The disadvantages of this model, however, can mean centralised control and points of failure. „If BitGo is bought by PayPal, if BitGo is hit by the Stability Act which may or may not be a reality in the United States, or if BitGo is hacked, the money disappears, and users really don’t have a lot of resources,“ explained Luongo.

In contrast, tBTC works with a network of validators in the block and part chain who individually contribute to the minting and support of tBTC, kept under control by the activity in the block chain.

„In a system like tBTC, you have to hack too many people to really impact the system, and then, even if all those people are hacked and all the Bitcoin is stolen, you end up getting all their signatory bonuses, so you end up being in a good place as a depositor. So not only is it more resistant to censorship, but it’s also a kind of security for the users‘ funds.
