How to Search BTC Blockchain OP_RETURN Information| Tokenview

**What is OP_RETURN？**OP_RETURN is the 'storage information' function of the Bitcoin network. This function supports writing hexadecimal characters to the Bitcoin blockchain.

Because Bitcoin developers believe that OP_RETURN will cause users to store too much non-transactional information on the Bitcoin network, which may affect the normal use of Bitcoin, and limit the size of stored information (40 bytes).

'OP_RETURN' can take advantage of the irreversible advantages of the BTC network to permanently record important information through the blockchain. Both 'chain lettering' and 'blockchain confession' use the Bitcoin 'OP_RETURN' function. Tokenview added a new 'remarks' information query function, by querying the transaction hash, you can visually see the 'remarks' information.

For example, El Salvador announced that the 'proposal of Bitcoin as a legal currency' was written into the Bitcoin block through 'OP_RETURN'.

'Blockchain confession' is also the function of storing 'OP_RETURN' in Bitcoin information by users to permanently record the confession information on the blockchain, such as a marriage proposal confession. Also use the Tokenview Bitcoin block explorer to query this information. Open the BTC explorer and check the 'Output' information in the transaction: 'Yuki will you marry me? Tetsu.'
