 To derive the address from the above calculated public key and timelock, we create a <tt>witness script</tt> which locks the funds until the <tt>timelock</tt>, and then checks the signature of the <tt>derived_key</tt>. The <tt>witness script</tt> is hashed with SHA256 to produce a 32-byte hash value that forms the <tt>witness program</tt> in the output script of the P2WSH address.
