The day before yesterday, HSBC issued a statement and someone kept asking me to take a look at the Bitcoin Thunderbolt collaboration with Nubit. After carefully reading the full article, analyzing the ecosystem, and Nubit doc, I roughly understand that their main target this time is BTC+RWA/DeFi Now this Thunderbolt is a soft fork upgrade, jointly initiated by miners from the Satoshi era, Bitcoin OG Whale, and the core technology team (@ domodata @ nubit_org). It is actually Nubit DA chain+BTC main chain data verification, which is more native than pure L1 such as FB and merlin Originality is an important prerequisite for value internalization. Thunderbolt's UTXO Bunding and OP_Cat BTC soft upgrade are actually about concatenating two data fragments to give Bitcoin native programmability. I have also discussed the importance of OP_cat for the BTC ecosystem before (DAPP can achieve native) At present, Nubit is equipped with some application layers of technical architecture, such as BitMM (DEFI transactions) and BitVisa (on chain authentication) What I am more bullish about is how to use OP-CAT and ZKP, BitVisa to achieve decentralized identity management on the Bitcoin main chain. By combining their resources (HSBC), whether it is credit loans in the form of RWA or on chain lending of BTC, off chain payments may really be within reach
