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.

the CPU while we're busy shutting down).

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 reverts commit c4988f5a1f.
This un-reverts the changes to store the service node info in the
database. This could easily just be its own commit instead of a
revert, but doing a revert is amusing (and easier in this case).
* Add get_service_node_list_state command for analytics
* Update service_node_list_state to search particular pubkey
* Service node list state sorts display results by longest waiting
* Fix up leftover todos/unused data structures
* Change get_service_node_list_state to print_sn
* add per-output unlock time field to transaction class
* get output unlock time (and relevant const fixes)
* move output unlocked check to separate function
* tx unlocked -> output unlocked in Blockchain
* per output unlock in tx creation; needs fork rules and testing
* per output unlock in tx prefix so it is signed...
also fix a couple typos/goofs
* wallet: check if using per output unlock time
* add rules.h and rules.cpp. git woopsie.
* update test for BlockchainDB changes
* Change tx v3 deregister to be a bool in tx header
* service_node_list: handle per output unlock times in contribution txs
* transaction: added verification of unlock_times.size()

Incorrect assumption that a transaction can be kept in the chain if it could
eventually become invalid, because if it were the chain would be split and
eventually these transaction would be dropped. But also that we should not
override the pre-existing logic which handles this case anyway.
on_generateblocks RPC call combines functionality from the on_getblocktemplate and on_submitblock RPC calls to allow rapid block creation. Difficulty is set permanently to 1 for regtest.
Makes use of FAKECHAIN network type, but takes hard fork heights from mainchain
Default reserve_size in generate_blocks RPC call is now 1. If it is 0, the following error occurs 'Failed to calculate offset for'.
Queries hard fork heights info of other network types
