Based on https://en.bitcoin.it/wiki/Script#Locktime

Word OP_CHECKLOCKTIMEVERIFY Opcode 177 Hex 0xb1 Input x Output x / fail Marks transaction as invalid if the top stack item is greater than the transaction's nLockTime field, otherwise script evaluation continues as though an OP_NOP was executed. Transaction is also invalid if any of these is true:

  1. the stack is empty
  2. the top stack item is negative
  3. the top stack item is greater than or equal to 500000000 while the transaction's nLockTime field is less than 500000000, or vice versa
  4. the input's nSequence field is equal to 0xffffffff. The precise semantics are described in BIP 0065.
