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).
2020-08-04Add txids with non-standard inputs to reject filterSuhas Daftuar
Our policy checks for non-standard inputs depend only on the non-witness portion of a transaction: we look up the scriptPubKey of the input being spent from our UTXO set (which is covered by the input txid), and the p2sh checks only rely on the scriptSig portion of the input. Consequently it's safe to add txids of transactions that fail these checks to the reject filter, as the witness is irrelevant to the failure. This is helpful for any situation where we might request the transaction again via txid (either from txid-relay peers, or if we might fetch the transaction via txid due to parent-fetching of orphans). Further, in preparation for future witness versions being deployed on the network, ensure that WITNESS_UNKNOWN transactions are rejected in AreInputsStandard(), so that transactions spending v1 (or greater) witness outputs will fall into this category of having their txid added to the reject filter.

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] Add several util unitsJohn Newbery
Adds the following util units and adds them to libbitcoin_util: - `util/url.cpp` takes `urlDecode` from `httpserver.cpp` - `util/error.cpp` takes `TransactionErrorString` from `node/transaction.cpp` and `AmountHighWarn` and `AmountErrMsg` from `ui_interface.cpp` - `util/fees.cpp` takes `StringForFeeReason` and `FeeModeFromString` from `policy/fees.cpp` - `util/rbf.cpp` takes `SignalsOptInRBF` from `policy/rbf.cpp` - 'util/validation.cpp` takes `FormatStateMessage` and `strMessageMagic` from 'validation.cpp`
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.

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.
2017-07-14Remove confusing MAX_BLOCK_BASE_SIZE.Gregory Maxwell
Some people keep thinking that MAX_BLOCK_BASE_SIZE is a separate size limit from the weight limit when it fact it is superfluous, and used in early tests before the witness data has been validated or just to compute worst case sizes. The size checks that use it would not behave any differently consensus wise if they were eliminated completely. Its correct value is not independently settable but is a function of the weight limit and weight formula. This patch just eliminates it and uses the scale factor as required to compute the worse case constants. It also moves the weight factor out of primitives into consensus, which is a more logical place for it.
