2020-11-25Add MAX_STANDARD_SCRIPTSIG_SIZE to policysanket1729
Bitcoin core has a standardness rule for max satisfaction script sig size. This PR adds to the policy header file so that it is documented along with along policy rules. The initial reasoning that 1650 is an implicit limit(would not reached assuming all other policy rules are being followed) is outdated. As we now know, bitcoin transactions can have spend conditions are more than just signatures and there may exist p2sh transactions involving 100 byte preimages that maybe non-standard because of this rule. Because this rule is no longer implicit, we should explicitly document it in policy header file
2020-10-30Only relay Taproot spends if next block has it activePieter Wuille
2020-10-12Make Taproot spends standard + policy limitsPieter Wuille
This adds a `TxoutType::WITNESS_V1_TAPROOT` for P2TR outputs, and permits spending them in standardness rules. No corresponding `CTxDestination` is added for it, as that isn't needed until we want wallet integration. The taproot validation flags are also enabled for mempool transactions, and standardness rules are added (stack item size limit, no annexes).

2019-04-10Remove access to node globals from wallet-linked codeRussell Yanofsky
Remove last few instances of accesses to node global variables from wallet code. Also remove accesses to node globals from code in policy/policy.cpp that isn't actually called by wallet code, but does get linked into wallet code. This is the last change needed to allow bitcoin-wallet tool to be linked without depending on libbitcoin_server.a, to ensure wallet code doesn't access node global state and avoid bugs like https://github.com/bitcoin/bitcoin/pull/15557#discussion_r267735431
2019-04-09[build] Move policy settings to new src/policy/settings unitJohn Newbery
This moves the following policy settings functions and globals to a new src/policy/settings unit in lib_server: - `incrementalRelayFee` - `dustRelayFee` - `nBytesPerSigOp` - `fIsBareMultisigStd` These settings are only required by the node and should not be accessed by other libraries.

2018-05-29policy: Treat segwit as always activeMarcoFalke
2018-05-05Policy to reject extremely small transactionsJohnson Lau
A transaction with 1 segwit input and 1 P2WPHK output has non-witness size of 82 bytes. Anything smaller than this have unnecessary malloc overhead and are not relayed/mined.
2018-05-05Add constant scriptCode policy in non-segwit scriptsJohnson Lau
This disables OP_CODESEPARATOR in non-segwit scripts (even in an unexecuted branch), and makes a positive FindAndDelete result invalid. This ensures that the scriptCode serialized in SignatureHash() is always the same as the script passing to the EvalScript.

Two new configuration options are added: * `-addresstype`, with options `legacy`, `p2sh`, and `bech32`. It controls what kind of addresses are produced by `getnewaddress`, `getaccountaddress`, and `createmultisigaddress`. * `-changetype`, with the same options, and by default equal to `-addresstype`, that controls what kind of change is used. All wallet private and public keys can be used for any type of address. Support for address types dependent on different derivation paths will need a major overhaul of how our internal detection of outputs work. I expect that that will happen for a next major version. The above also applies to imported keys, as having a distinction there but not for normal operations is a disaster for testing, and probably for comprehension of users. This has some ugly effects, like needing to associate the provided label to `importprivkey` with each style address for the corresponding key. To deal with witness outputs requiring a corresponding redeemscript in wallet, three approaches are used: * All SegWit addresses created through `getnewaddress` or multisig RPCs explicitly get their redeemscripts added to the wallet file. This means that downgrading after creating a witness address will work, as long as the wallet file is up to date. * All SegWit keys in the wallet get an _implicit_ redeemscript added, without it being written to the file. This means recovery of an old backup will work, as long as you use new software. * All keypool keys that are seen used in transactions explicitly get their redeemscripts added to the wallet files. This means that downgrading after recovering from a backup that includes a witness address will work. These approaches correspond to solutions 3a, 1a, and 5a respectively from https://gist.github.com/sipa/125cfa1615946d0c3f3eec2ad7f250a2. As argued there, there is no full solution for dealing with the case where you both downgrade and restore a backup, so that's also not implemented. `dumpwallet`, `importwallet`, `importmulti`, `signmessage` and `verifymessage` don't work with SegWit addresses yet. They're remaining TODOs, for this PR or a follow-up. Because of that, several tests unexpectedly run with `-addresstype=legacy` for now.

2017-09-11Use a sensible default for blockmaxweightMatt Corallo
No sensible user will ever keep the default settings here, so not having sensible defaults only serves to screw users who are paying less attention, which makes for terrible defaults.
2017-09-11Deprecate confusing blockmaxsize, fix getmininginfo outputMatt Corallo
* This removes block-size-limiting code in favor of GBT clients doing the limiting themselves (if at all). * -blockmaxsize is deprecated and only used to calculate an implied blockmaxweight, addressing confusion from multiple users. * getmininginfo's currentblocksize return value was returning garbage values, and has been removed, also removing a GetSerializeSize call in some block generation inner loops and potentially addressing some performance edge cases.
2017-07-17Remove factor of 3 from definition of dust.Alex Morcos
This redefines dust to be the value of an output such that it would cost that value in fees to (create and) spend the output at the dust relay rate. The previous definition was that it would cost 1/3 of the value. The default dust relay rate is correspondingly increased to 3000 sat/kB so the actual default dust output value of 546 satoshis for a non-segwit output remains unchanged. This commit is a refactor only unless a dustrelayfee is passed on the commandline in which case that number now needs to be increased by a factor of 3 to get the same behavior. -dustrelayfee is a hidden command line option. Note: It's not exactly a refactor due to edge case changes in rounding as evidenced by the required change to the unit test.

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.
