This test is meant to exercise activation of the first version bits soft fork |
||||
This soft fork will activate the following BIPS: |
||||
BIP 68 - nSequence relative lock times |
||||
BIP 112 - CHECKSEQUENCEVERIFY |
||||
BIP 113 - MedianTimePast semantics for nLockTime |
||||
|
||||
regtest lock-in with 108/144 block signalling |
||||
activation after a further 144 blocks |
||||
|
||||
mine 82 blocks whose coinbases will be used to generate inputs for our tests |
||||
mine 61 blocks to transition from DEFINED to STARTED |
||||
mine 144 blocks only 100 of which are signaling readiness in order to fail to change state this period |
||||
mine 144 blocks with 108 signaling and verify STARTED->LOCKED_IN |
||||
mine 140 blocks and seed block chain with the 82 inputs will use for our tests at height 572 |
||||
mine 3 blocks and verify still at LOCKED_IN and test that enforcement has not triggered |
||||
mine 1 block and test that enforcement has triggered (which triggers ACTIVE) |
||||
Test BIP 113 is enforced |
||||
Mine 4 blocks so next height is 580 and test BIP 68 is enforced for time and height |
||||
Mine 1 block so next height is 581 and test BIP 68 now passes time but not height |
||||
Mine 1 block so next height is 582 and test BIP 68 now passes time and height |
||||
Test that BIP 112 is enforced |
||||
|
||||
Various transactions will be used to test that the BIPs rules are not enforced before the soft fork activates |
||||
And that after the soft fork activates transactions pass and fail as they should according to the rules. |
||||
For each BIP, transactions of versions 1 and 2 will be tested. |
||||
---------------- |
||||
BIP 113: |
||||
bip113tx - modify the nLocktime variable |
||||
|
||||
BIP 68: |
||||
bip68txs - 16 txs with nSequence relative locktime of 10 with various bits set as per the relative_locktimes below |
||||
|
||||
BIP 112: |
||||
bip112txs_vary_nSequence - 16 txs with nSequence relative_locktimes of 10 evaluated against 10 OP_CSV OP_DROP |
||||
bip112txs_vary_nSequence_9 - 16 txs with nSequence relative_locktimes of 9 evaluated against 10 OP_CSV OP_DROP |
||||
bip112txs_vary_OP_CSV - 16 txs with nSequence = 10 evaluated against varying {relative_locktimes of 10} OP_CSV OP_DROP |
||||
bip112txs_vary_OP_CSV_9 - 16 txs with nSequence = 9 evaluated against varying {relative_locktimes of 10} OP_CSV OP_DROP |
||||
bip112tx_special - test negative argument to OP_CSV |
