On-chain technology refers to the method of directly storing and processing data on the blockchain, that is, all transactions and information are recorded in the distributed ledger of the blockchain. This technology has the characteristics of transparency, security, and tamper-proof, but it also has the problems of slow transaction speed and high resource consumption.↵↵In comparison, Off-chain technology involves transaction and data processing that occurs outside the blockchain ledger. It alleviates the burden on the blockchain by transferring partial data or calculations offline, thereby improving  transaction speed and reducing costs. The key to Off-chain technology is to ensure security and integrity during the transition between on-chain and off-chain processes."}]}],"pr":"b9a4de6a434045fa6c968ae1493f036c6b5b340283a67a45d919f4655f0805e6"}
