The 10 minute one will never trigger for 0 blocks, as it's still
fairly likely to happen even without the actual hash rate changing
much, so we add a 20 minute window, where it will (for 0 blocks)
and a one hour window.
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.
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

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.

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.

This avoids the miner erroring out trying to submit blocks
to a core that's already shut down (and avoids pegging
the CPU while we're busy shutting down).
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.

To help protect one's privacy from traffic volume analysis
for people using Tor or I2P. This will really fly once we
relay txes on a timer rather than on demand, though.
Off by default for now since it's wasteful and doesn't bring
anything until I2P's in.
This happens for every historical tx when syncing, and the
unnecessary parsing is actually showing up on profile.
Since these are kept cached for just one block, this does
not increase memory usage after syncing.
This removes some small amount of fingerprinting entropy.
There is no consensus rule to require this since this field
is technically free form, and a transaction is free to have
custom data in it.

This avoids constant rechecking of the same things each time
a miner asks for the block template. The tx pool maintains
a cookie to allow users to detect when the pool state changed,
which means the block template needs rebuilding.

This can happen if a peer tries to obtain the next span from other
peers if that span is needed for not downloaded yet. Also if the
peer maliciously requests a non existent block hash.
A key image may be present more than once if all but one of the
txes spending that key image are coming from blocks. When loading
a txpool from storage, we must load the one that's not from a
block first to avoid rejection
Takes about 10 ms, which takes pretty much all of the get_info
RPC, which is called pretty often from wallets.
Also add a new lock so we don't need to lock the blockchain lock,
which will avoid blocking for a long time when calling the getinfo
RPC while syncing. Users of get_difficulty_for_next_block who need
the lock will have locked it already.
When #3303 was merged, a cyclic dependency chain was generated:
libdevice <- libcncrypto <- libringct <- libdevice
This was because libdevice needs access to a set of basic crypto operations
implemented in libringct such as scalarmultBase(), while libringct also needs
access to abstracted crypto operations implemented in libdevice such as
ecdhEncode(). To untangle this cyclic dependency chain, this patch splits libringct
into libringct_basic and libringct, where the basic crypto ops previously in
libringct are moved into libringct_basic. The cyclic dependency is now resolved
thanks to this separation:
libcncrypto <- libringct_basic <- libdevice <- libcryptonote_basic <- libringct
This eliminates the need for crypto_device.cpp and rctOps_device.cpp.
Also, many abstracted interfaces of hw::device such as encrypt_payment_id() and
get_subaddress_secret_key() were previously implemented in libcryptonote_basic
(cryptonote_format_utils.cpp) and were then called from hw::core::device_default,
which is odd because libdevice is supposed to be independent of libcryptonote_basic.
Therefore, those functions were moved to device_default.cpp.
Fix the way the REAL mode is handle:
Let create_transactions_2 and create_transactions_from construct the vector of transactions.
Then iterate on it and resign.
We just need to add 'outs' list in the TX struct for that.
Fix default secret keys value when DEBUG_HWDEVICE mode is off
The magic value (00...00 for view key and FF..FF for spend key) was not correctly set
when DEBUG_HWDEVICE was off. Both was set to 00...00.
Add sub-address info in ABP map in order to correctly display destination sub-address on device
Fix DEBUG_HWDEVICE mode:
- Fix compilation errors.
- Fix control device init in ledger device.
- Add more log.
Fix sub addr control
Fix debug Info

9f9e095a Use `genesis_tx` parameter in `generate_genesis_block`. #3261 (Jean Pierre Dudey)
* src/cryptnote_config.h: The constant `config::testnet::GENESIS_TX` was
changed to be the same as `config::GENESIS_TX` (the mainnet's transaction)
because the mainnet's transaction was being used for both networks.
* src/cryptonote_core/cryptonote_tx_utils.cpp: The `generate_genesis_block` function
was ignoring the `genesis_tx` parameter, and instead it was using the `config::GENESIS_TX`
constant. That's why the testnet genesis transaction was changed. Also five lines of unused
code were removed.

The basic approach it to delegate all sensitive data (master key, secret
ephemeral key, key derivation, ....) and related operations to the device.
As device has low memory, it does not keep itself the values
(except for view/spend keys) but once computed there are encrypted (with AES
are equivalent) and return back to monero-wallet-cli. When they need to be
manipulated by the device, they are decrypted on receive.
Moreover, using the client for storing the value in encrypted form limits
the modification in the client code. Those values are transfered from one
C-structure to another one as previously.
The code modification has been done with the wishes to be open to any
other hardware wallet. To achieve that a C++ class hw::Device has been
introduced. Two initial implementations are provided: the "default", which
remaps all calls to initial Monero code, and the "Ledger", which delegates
all calls to Ledger device.
When a block is added as part of a chunk (when syncing historical
blocks), a block may end up already in the blockchain if it was
added to the queue before being added to the chain (though it's
not clear how that could happen, but it's an implementation detail)
and thus may not be added to the chain when add_block is called.
This would cause m_blocks_txs_check to not be cleared, causing it
to get out of sync at next call, and thus wrongfully reject the
next block.
