Nubit founder: The root cause of the BTCFi problem lies in the lack of security guarantees on the Bitcoin mainnet

According to Foresight News, Nubit founder Yu Feng tweeted that many protocols in the current BTCFi ecosystem forge lock-in through offline pre signed transactions, which does not truly lock Bitcoin on the mainnet, but gives a false impression of being "locked". Users can submit multiple pre signed transactions with the same UTXO, allowing multiple protocols to count it as TVL, but in reality, this Bitcoin is not really locked anywhere. This operation has led to false inflation of TVL and serious trust issues. The founder of Nubit proposed two solutions: one is to truly put transactions on chain and lock funds through Bitcoin script addresses; The second is to use zero knowledge proof design to make the lock warehouse transparent and secure, avoiding the risk of double spending.
