We need to include a refund clause in the contract:\n\n_“If Robosats does not reveal the secret within 24 hours,  the Trader can recover the funds”_\n\nThis time-locked refund clause also helps achieve atomicity. There is no need to worry about a partial payment state. In the event of a failure, each participant individually put the time-locked refund transaction on the blockchain to retrieve their funds.\n\nThe `OP_CHECKLOCKTIMEVERIFY`, or `OP_CLTV`, opcode works by allowing the creator of a transaction to specify a specific block height or timestamp in the future when the transaction can be added to the blockchain and become valid."},

Fortunately, digital signatures provide much stronger security guarantees. They are like special stamps and codes that help to prove that a message is coming from whom we expect.\n\n\n\n"},
