* fees: Reduce minimum relay fee to 0.001 DOGE, final change from tx to 0.01Michi Lumin2021-08-111-1/+1

* Don't re-check AuxPoW when sending data to peersShibe2021-02-081-3/+3
| | | | | | Checking scrypt PoW is expensive and needless in this case. All block headers are already checked when they are accepted, and they will be checked again on the receiving end.
* Halve timeoutsRoss Nicoll2021-02-071-4/+4
|
* Adapt block download timeouts to DogecoinRoss Nicoll2021-02-051-2/+2
| | | | | Block download timeouts are expressed as a fraction of block interval time, so Dogecoin values have been too aggressive. Matching Bitcoin values as a starting point.
* Default policy: reduce default mempool expiry timePatrick Lodder2021-01-271-1/+1
| | | | | | | | | | | | | | | | | Reduces DEFAULT_MEMPOOL_EXPIRY from 336 hours to 24 hours. Motivation is that while blocks are empty, un-relayable tx are stuck in mempools for a long time and effectively locking utxo for 2 weeks until they can be respent, if no RBF opt-in was performed (most wallet implementations do not do RBF opt-in.) As the expectation is that block space will not be fully utilized for the foreseeable future, and therefore, as long as this is the case, no valid transaction should ever live in the mempool for more than a couple of minutes. This default setting can be overridden with the -mempoolexpiry parameter by individual node operators to a value (expressed in hours) that makes the most sense for the use cases the node serves.

* Clean up RPC tests (#1465)Ross Nicoll2018-09-191-1/+1
| | | | | | | | | | * Enable full block tests * Fix invalidblocktest * Move watch only address funding to immediately before it's used, so node 0 doesn't spend the output before it checks it later. * Fix `fundrawtransaction` tests and sanitize fee calculation at the same time * Correct resolution of chain parameters when validating tx inputs, especially from previous coinbase transactions * Set block versions on full block tests so that the generated blocks are AuxPoW compatible
* Enforce minor Dogecoin parameters (#1427)Ross Nicoll2018-09-191-9/+9
| | | | | | * Minimum number of blocks and blockchain size are increased for pruning. In comparison to Bitcoin this uses 24 hours as a minimum, rather than 48, although given blocks are rarely full this likely reflects a lot longer in reality. * Multiply fork detection parameters by 5. The wall clock time elapsed for "long" forks is therefore half that of Bitcoin, but IMHO those figures are excessive for a chain with 1 minute block times. * BIP16 and BIP30 have both been enabled on Dogecoin since inception and should not be conditional.
* Bring 1.14 fees in line with 1.10 (#1425)Ross Nicoll2018-09-191-2/+2
| | | | | | * Disable free transactions * Updating remaining fee calculation constants * Round up to the nearest 1k, not up 1k so the UI fee estimator is correct
* Add Dogecoin current fee calculation logic (#1413)Ross Nicoll2018-09-191-3/+3
| | | Introduces 1 COIN/kb fees, rounded up to the next 1 COIN.
* Modify chain consensus parameters to be height aware (#1396)Ross Nicoll2018-09-191-4/+4
| | | | | | | | | * Modify chain consensus parameters to be height aware * Correct implementation of simplified rewards in parameters * Correct max money * Use base block version in IsSuperMajority() instead of full version * Correct mining of blocks in AuxPoW tests * Add in missing pre-AuxPoW consensus checks
* Merge AuxPoW support from NamecoreRoss Nicoll2018-09-191-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | Introduce assumevalid setting to skip presumed valid scripts.Gregory Maxwell2017-01-131-0/+3

A new option is introduced "assumevalid" which specifies a block whos ancestors we assume all have valid scriptsigs and so we do not check them when they are also burried under the best header by two weeks worth of work. Unlike checkpoints this has no influence on consensus unless you set it to a block with an invalid history. Because of this it can be easily be updated without risk of influencing the network consensus. This results in a massive IBD speedup. This approach was independently recommended by Peter Todd and Luke-Jr since POW based signature skipping (see PR#9180) does not have the verifiable properties of a specific hash and may create bad incentives. The downside is that, like checkpoints, the defaults bitrot and older releases will sync slower. On the plus side users can provide their own value here, and if they set it to something crazy all that will happen is more time will be spend validating signatures. Checkblocks and checklevel are also moved to the hidden debug options: Especially now that checkblocks has a low default there is little need to change these settings, and users frequently misunderstand them as influencing security or IBD speed. By hiding them we offset the space added by this new option.
