Friends who are currently researching the Bitcoin ecosystem can pay attention to @ Ducatstable. On the morning of November 20th at 11:00 am (Beijing time), they will officially activate their collaboration with Chainlink to create the first native oracle on the first layer of Bitcoin. For DeFi professionals, this holds great significance. Let me briefly explain why I think it's worth paying attention to: • Truly 'unmanaged' design: Many projects claim decentralization, but the price oracle behind it is self controlled. Once falsified, user funds become passive. Ducat directly hands over the oracle to Chainlink, the most mature decentralized oracle network in the industry, and does not touch this "life and death power" at home. Native oracle on Bitcoin L1: Previously, many innovations of Chainlink were in the EVM ecosystem. This time, we are moving the mature oracle architecture to the first layer of Bitcoin and creating a verifiable financial infrastructure on the most decentralized network. • Transparent mechanism and rules written on the chain: The 'vault' opened by users on Ducat is essentially a UTXO, with collateral and debt information written in OP-RETURN. Every time a warehouse is opened, borrowed, or repaid, a quote is requested from Chainlink, which contains information such as the amount borrowed, the price to be cleared, and the timestamp. When the mortgage rate drops from 160% to 135%, Chainlink detects that it will trigger liquidation conditions, and anyone can participate in liquidation with open rules and opportunities for everyone. The security boundary is relatively restrained: Ducat further removes the signature ability of the oracle, which means that the oracle itself cannot directly move funds and is only responsible for feeding and triggering conditions, which is safer than many "feeding+signature integrated" solutions. In the long run, this combination is laying the foundation for basic modules such as vaults, lending, stablecoins, and clearing on Bitcoin L1. If you are bullish on Bitcoin DeFi, these underlying protocols are worth tracking in advance. In the next few weeks, Ducat will test its integration with Chainlink's oracle on testnet Testnet： https://app. ((ducatprotocol.com)) Those interested can go ahead and play the testnet to familiarize themselves with the gameplay. Perhaps it will become a core infrastructure in Bitcoin's DeFi layer in the future. Testnet - https://app. ((ducatprotocol.com)) Discord - https://discord.gg/ducat
