<p>Like the question states, is it currently possible in the Bitcoin blockchain to send coins to an address, but have the transaction written into a block or validated only after two parties sign messages into the blockchain that the funds should be released?</p>

<p>If it does exist, how does this technically work? </p>

<p>A comment describing or linking to something similar to this or on the off-chain level would be appreciated too.</p>
