#CKB helps Bitcoin ecosystem:
When we first mention ckb, the first thing that comes to mind is the RGB protocol. The development of the RGB protocol is inseparable from the technical promotion of the ckb chain. The two things promote each other. If this round of Bitcoin ecology wants to develop better, it must be inseparable from the application of the RGB protocol. However, the application of the RGB protocol and the RGB++ protocol is directly related to the entire technical development of the ckb chain.
Build a CKB transaction and application:
(6) Verify Bitcoin Transactions Based on the Bitcoin block header data written by Relayer, the light client on CKB can verify whether a Bitcoin transaction actually exists on the Bitcoin chain, whether its UTXO information is valid, and whether it can match the information provided by the Commitment. It can also verify whether the commitment in the Bitcoin transaction matches the CKB transaction data.
(7) If the results of the previous verification are consistent, the transaction on the CKB chain will be automatically submitted to the chain by the repeater or aggregator. Since CKB has achieved complete account abstraction and masterless contract capabilities, the transaction verification does not require the user to provide a signature. It only needs to provide proof that the Bitcoin transaction has been on the chain based on the verification results of the previous step to pass the verification. If it passes the verification, the CKB transaction will be on the chain. If it fails, it means that the CKB transaction has been modified after the Bitcoin transaction was submitted, and the transaction data does not match the Commitment, then the transaction will fail.
