* Use CAmount for amountsRoss Nicoll2021-08-081-1/+2
| | | | | | | | | | Use CAmount rather than unsigned int for amounts for consistency with other fee rate amounts. This does change the type from unsigned int to unsigned int64, and while it is unlikely anyone would need a dust limit higher than unsigned int, again this ensures the theoretical maximum is in line with other rates.

* Create v1 transactions for compatibility with 1.10 (#1485)Ross Nicoll2018-09-191-1/+2
| | | | Create v1 transactions for compatibility with 1.10. See https://github.com/bitcoin/bips/blob/master/bip-0068.mediawiki for context. This should NOT be merged into 1.16.

* Merge AuxPoW support from NamecoreRoss Nicoll2018-09-194-43/+230
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Changes are as below: Wrap CBlockHeader::nVersion into a new class (CBlockVersion). This allows to take care of interpreting the field into a base version, auxpow flag and the chain ID. Update getauxblock.py for new 'generate' RPC call. Add 'auxpow' to block JSON. Accept auxpow as PoW verification. Add unit tests for auxpow verification. Add check for memory-layout of CBlockVersion. Weaken auxpow chain ID checks for the testnet. Allow Params() to overrule when to check the auxpow chain ID and for legacy blocks. Use this to disable the checks on testnet. Introduce CPureBlockHeader. Split the block header part that is used by auxpow and the "real" block header (that uses auxpow) to resolve the cyclic dependency between the two. Differentiate between uint256 and arith_uint256. This change was done upstream, modify the auxpow code. Add missing lock in auxpow_tests. Fix REST header check for auxpow headers. Those can be longer, thus take that into account. Also perform the check actually on an auxpow header. Correctly set the coinbase for getauxblock results. Call IncrementExtraNonce in getauxblock so that the coinbase is actually initialised with the stuff it should be. (BIP30 block height and COINBASE_FLAGS.) Implement getauxblock plus regression test. Turn auxpow test into FIXTURE test. This allows using of the Params() calls. Move CMerkleTx code to auxpow.cpp. Otherwise we get linker errors when building without wallet. Fix rebase with BIP66. Update the code to handle BIP66's nVersion=3. Enforce that auxpow parent blocks have no auxpow block version. This is for compatibility with namecoind. See also https://github.com/namecoin/namecoin/pull/199. Move auxpow-related parameters to Consensus::Params.

* Get rid of nType and nVersionPieter Wuille2016-11-072-15/+16
| | | | | | | | | | | Remove the nType and nVersion as parameters to all serialization methods and functions. There is only one place where it's read and has an impact (in CAddress), and even there it does not impact any of the recursively invoked serializers. Instead, the few places that need nType or nVersion are changed to read it directly from the stream object, through GetType() and GetVersion() methods which are added to all stream classes.
* Make GetSerializeSize a wrapper on top of CSizeComputerPieter Wuille2016-11-071-1/+1
| | | | | | | | | | | Given that in default GetSerializeSize implementations created by ADD_SERIALIZE_METHODS we're already using CSizeComputer(), get rid of the specialized GetSerializeSize methods everywhere, and just use CSizeComputer. This removes a lot of code which isn't actually used anywhere. For CCompactSize and CVarInt this actually removes a more efficient size computing algorithm, which is brought back in a later commit.

|/ | | | | | | | | | | This switches the Merkle tree logic for blocks to one that runs in constant (small) space. The old code is moved to tests, and a new test is added that for various combinations of block sizes, transaction positions to compute a branch for, and mutations: * Verifies that the old code and new code agree for the Merkle root. * Verifies that the old code and new code agree for the Merkle branch. * Verifies that the computed Merkle branch is valid. * Verifies that mutations don't change the Merkle root. * Verifies that mutations are correctly detected.
