By comparing the argument to CHECKSEQUENCEVERIFY against the nSequence field, we indirectly verify a desired minimum age of the the output being spent; until that relative age has been reached any script execution pathway including the CHECKSEQUENCEVERIFY will fail to validate, causing the transaction not to be selected for inclusion in a block.// | + | //[[dido:public:ra:xapend:xapend.b_stds:defact:bitcoin:bips:bip_0068| BIP68]] prevents a non-final transaction from being selected for inclusion in a block until the corresponding input has reached the specified age, as measured in [[dido:public:ra:xapend:xapend.a_glossary:b:block_height|block-height]] or block-time.
