b8787f43 ArticMine's new block weight algorithm (moneromooo-monero)
2019-03-04 12:09:13 +02:00

b8787f4302
ArticMine's new block weight algorithm
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.

blockchain: add --reorg-notify
This will trigger if a reorg is seen. This may be used to do things
like stop automated withdrawals on large reorgs.

%s is replaced by the height at the split point
%h is replaced by the height of the new chain
%n is replaced by the number of new blocks after the reorg

Pruning
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.

blockchain: fix wrong hf version when popping multiple blocks
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

cryptonote_core: revert extra_tx_map
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.

blockchain: avoid unnecessary DB lookups when syncing
Some of the inputs for block in a span will be from other earlier
blocks in that span. Keep track of those outputs so we don't have
to look them up again after those early blocks are added to the
blockchain.
