This if statement is a little obtuse and using braces here improves readability.

For the sake of a little repetition, make code more readable.
2016-02-14BIP112: Implement CHECKSEQUENCEVERIFYMark Friedenbach
- Replace NOP3 with CHECKSEQUENCEVERIFY (BIP112) <nSequence> CHECKSEQUENCEVERIFY -> <nSequence> - Fails if txin.nSequence < nSequence, allowing funds of a txout to be locked for a number of blocks or a duration of time after its inclusion in a block. - Pull most of CheckLockTime() out into VerifyLockTime(), a local function that will be reused for CheckSequence() - Add bitwise AND operator to CScriptNum - Enable CHECKSEQUENCEVERIFY as a standard script verify flag - Transactions that fail CSV verification will be rejected from the mempool, making it easy to test the feature. However blocks containing "invalid" CSV-using transactions will still be accepted; this is *not* the soft-fork required to actually enable CSV for production use.

SequenceLocks functions are used to evaluate sequence lock times or heights per BIP 68. The majority of this code is copied from maaku in #6312 Further credit: btcdrak, sipa, NicolasDorier

2015-10-01Accept any sequence of PUSHDATAs in OP_RETURN outputsPeter Todd
Previously only one PUSHDATA was allowed, needlessly limiting applications such as matching OP_RETURN contents with bloom filters that operate on a per-PUSHDATA level. Now any combination that passes IsPushOnly() is allowed, so long as the total size of the scriptPubKey is less than 42 bytes. (unchanged modulo non-minimal PUSHDATA encodings) Also, this fixes the odd bug where previously the PUSHDATA could be replaced by any single opcode, even sigops consuming opcodes such as CHECKMULTISIG. (20 sigops!)
2015-10-01Add IsPushOnly(const_iterator pc)Peter Todd
Allows IsPushOnly() to be applied to just part of the script for OP_RETURN outputs.
2015-10-01Make TX_SCRIPTHASH clear vSolutionsRet firstPeter Todd
Previously unlike other transaction types the TX_SCRIPTHASH would not clear vSolutionsRet, which means that unlike other transaction types if it was called twice in a row you would get the result of the previous invocation as well.

Transactions that fail CLTV verification will be rejected from the mempool, making it easy to test the feature. However blocks containing "invalid" CLTV-using transactions will still be accepted; this is *not* the soft-fork required to actually enable CLTV for production use.
2015-06-21Replace NOP2 with CHECKLOCKTIMEVERIFY (BIP65)Peter Todd
<nLockTime> CHECKLOCKTIMEVERIFY -> <nLockTime> Fails if tx.nLockTime < nLockTime, allowing the funds in a txout to be locked until some block height or block time in the future is reached. Only the logic and unittests are implemented; this commit does not have any actual soft-fork logic in it. Thanks to Pieter Wuille for rebase. Credit goes to Gregory Maxwell for the suggestion of comparing the argument against the transaction nLockTime rather than the current time/blockheight directly.
