2022-04-18Add view tags to outputs to reduce wallet scanning timej-berman1-9/+23
Implements view tags as proposed by @UkoeHB in MRL issue https://github.com/monero-project/research-lab/issues/73 At tx construction, the sender adds a 1-byte view tag to each output. The view tag is derived from the sender-receiver shared secret. When scanning for outputs, the receiver can check the view tag for a match, in order to reduce scanning time. When the view tag does not match, the wallet avoids the more expensive EC operations when deriving the output public key using the shared secret.

2022-03-10Remove footgun doc comment in miner TX validationLuke Parker1-3/+0
This comment suggests this check is unnecessary, when it is completely necessary as miner TXs can have multiple outputs *which is a statement directly, and incorrectly, contradicted by this comment*. While I don't ever see someone removing this code and getting their edits merged into Monero, someone inexperienced who thinks they're cleaning old code may break their own work, and then there's really just zero benefit to keeping this around.

Data provided: - major fork version - current height - previous block id - RandomX seed hash - network difficulty - median block weight - coins mined by the network so far - mineable mempool transactions

2021-02-09Remove unused variables in monero codebaseKevin Barbour1-1/+0
There are quite a few variables in the code that are no longer (or perhaps never were) in use. These were discovered by enabling compiler warnings for unused variables and cleaning them up. In most cases where the unused variables were the result of a function call the call was left but the variable assignment removed, unless it was obvious that it was a simple getter with no side effects.

Miners with MLSAG txes which they'd already verified included a couple in that block, but the consensus rules had changed in the meantime, so that block is technically invalid and any node which did not already have those two txes in their txpool could not sync. Grandfather them in, since it has no effect in practice.

2020-07-08blockchain: fix timestamp/difficulty cache getting out of syncmoneromooo-monero1-1/+16
The cache is discarded when a block is popped, but then gets rebuilt when the difficulty for next block is requested. While this is all properly locked, it does not take into account the delay caused by a database transaction being only committed (and thus its effects made visible to other threads) later on, which means another thread could request difficulty between the pop and the commit, which would end up using stale database view to build the cache, but that cache would not be invalidated again when the transaction gets committed, which would cause the cache to not match the new database data. To fix this, we now keep track of when the cache is invalidated so we can invalidate it again upon database transaction commit to ensure it gets calculated again with fresh data next time it is nedeed.

2019-09-28blockchain: tweak fee as a function of median valuesmoneromooo-monero1-1/+2
Use the lesser of the short and long terms medians, rather then the long term median alone From ArticMine: I found a bug in the new fee calculation formula with using only the long term median It actually needs to be the lesser of the long term median and the old (modified short term median) short term median with the last 10 blocks calculated as empty Yes the issue occurs if there is a large long term median and, the short term median then falls and tries to then rise again The fees are could be not high enough for example LTM and STM rise to say 2000000 bytes STM falls back to 300000 bytes Fees are now based on 2000000 bytes until LTM also falls So the STM is could prevented from rising back up STM short term median LTM long term median
2019-09-27monerod can now sync from pruned blocksmoneromooo-monero1-50/+194
If the peer (whether pruned or not itself) supports sending pruned blocks to syncing nodes, the pruned version will be sent along with the hash of the pruned data and the block weight. The original tx hashes can be reconstructed from the pruned txes and theur prunable data hash. Those hashes and the block weights are hashes and checked against the set of precompiled hashes, ensuring the data we received is the original data. It is currently not possible to use this system when not using the set of precompiled hashes, since block weights can not otherwise be checked for validity. This is off by default for now, and is enabled by --sync-pruned-blocks

2019-04-14blockchain_db: fix db txn ending too earlymoneromooo-monero1-29/+23
The db txn in add_block ending caused the entire overarching batch txn to stop. Also add a new guard class so a db txn can be stopped in the face of exceptions. Also use a read only db txn in init when the db itself is read only, and do not save the max tx size in that case.

b8787f43 ArticMine's new block weight algorithm (moneromooo-monero)
2019-03-04ArticMine's new block weight algorithmmoneromooo-monero1-21/+118
This curbs runaway growth while still allowing substantial spikes in block weight Original specification from ArticMine: here is the scaling proposal Define: LongTermBlockWeight Before fork: LongTermBlockWeight = BlockWeight At or after fork: LongTermBlockWeight = min(BlockWeight, 1.4*LongTermEffectiveMedianBlockWeight) Note: To avoid possible consensus issues over rounding the LongTermBlockWeight for a given block should be calculated to the nearest byte, and stored as a integer in the block itself. The stored LongTermBlockWeight is then used for future calculations of the LongTermEffectiveMedianBlockWeight and not recalculated each time. Define: LongTermEffectiveMedianBlockWeight LongTermEffectiveMedianBlockWeight = max(300000, MedianOverPrevious100000Blocks(LongTermBlockWeight)) Change Definition of EffectiveMedianBlockWeight From (current definition) EffectiveMedianBlockWeight = max(300000, MedianOverPrevious100Blocks(BlockWeight)) To (proposed definition) EffectiveMedianBlockWeight = min(max(300000, MedianOverPrevious100Blocks(BlockWeight)), 50*LongTermEffectiveMedianBlockWeight) Notes: 1) There are no other changes to the existing penalty formula, median calculation, fees etc. 2) There is the requirement to store the LongTermBlockWeight of a block unencrypted in the block itself. This is to avoid possible consensus issues over rounding and also to prevent the calculations from becoming unwieldy as we move away from the fork. 3) When the EffectiveMedianBlockWeight cap is reached it is still possible to mine blocks up to 2x the EffectiveMedianBlockWeight by paying the corresponding penalty. Note: the long term block weight is stored in the database, but not in the actual block itself, since it requires recalculating anyway for verification.

2019-01-22Pruningmoneromooo-monero1-3/+93
The blockchain prunes seven eighths of prunable tx data. This saves about two thirds of the blockchain size, while keeping the node useful as a sync source for an eighth of the blockchain. No other data is currently pruned. There are three ways to prune a blockchain: - run monerod with --prune-blockchain - run "prune_blockchain" in the monerod console - run the monero-blockchain-prune utility The first two will prune in place. Due to how LMDB works, this will not reduce the blockchain size on disk. Instead, it will mark parts of the file as free, so that future data will use that free space, causing the file to not grow until free space grows scarce. The third way will create a second database, a pruned copy of the original one. Since this is a new file, this one will be smaller than the original one. Once the database is pruned, it will stay pruned as it syncs. That is, there is no need to use --prune-blockchain again, etc.

Since we keep track of the hf version in the db, we pick it up from there instead of doing the full reorg call, which is quite expensive

While the lookups are faster, the zeroCommit calls have to be done again when storing the new outputs in the db, which ends up making the whole thing slower after all, and the ways this can be cached aren't very nice code wise, so let's forget it since the gains aren't very large anyway.
