This updates the coinbase transactions to reward service nodes periodically rather than every block. If you recieve a service node reward this reward will be delayed x blocks, if you receive another reward to the same wallet before those blocks have been completed it will be added to your total and all will be paid out after those x blocks has passed. For example if our batching interval is 2 blocks: Block 1 - Address A receives reward of 10 oxen - added to batch Block 2 - Address A receives reward of 10 oxen - added to batch Block 3 - Address A is paid out 20 oxen. Batching accumulates a small reward for all nodes every block The batching of service node rewards allows us to drip feed rewards to service nodes. Rather than accruing each service node 16.5 oxen every time they are pulse block leader we now reward every node the 16.5 / num_service_nodes every block and pay each wallet the full amount that has been accrued after a period of time (Likely 3.5 days). To spread each payment evenly we now pay the rewards based on the address of the recipient. This modulus of their address determines which block the address should be paid and by setting the interval to our service_node_batching interval we can guarantee they will be paid out regularly and evenly distribute the payments for all wallets over this |

Oxen Blockchain Utilities

Introduction
The blockchain utilities allow one to import and export the blockchain.
Usage:
See also each utility's "--help" option.
Export an existing blockchain database
$ oxen-blockchain-export
This loads the existing blockchain and exports it to $OXEN_DATA_DIR/export/blockchain.raw
Import the exported file
$ oxen-blockchain-import
This imports blocks from $OXEN_DATA_DIR/export/blockchain.raw
(exported using the
oxen-blockchain-export
tool as described above) into the current database.
Defaults: --batch on
, --batch size 20000
, --verify on
Batch size refers to number of blocks and can be adjusted for performance based on available RAM.
Verification should only be turned off if importing from a trusted blockchain.
If you encounter an error like "resizing not supported in batch mode", you can just re-run
the oxen-blockchain-import
command again, and it will restart from where it left off.
## use default settings to import blockchain.raw into database
$ oxen-blockchain-import
## fast import with large batch size, database mode "fastest", verification off
$ oxen-blockchain-import --batch-size 20000 --database lmdb#fastest --verify off
Import options
--input-file
specifies input file path for importing
default: <data-dir>/export/blockchain.raw
--output-file
specifies output file path to export to
default: <data-dir>/export/blockchain.raw
--block-stop
stop at block number
--database <database type>
--database <database type>#<flag(s)>
database type: lmdb, memory
flags:
The flag after the # is interpreted as a composite mode/flag if there's only one (no comma separated arguments).
The composite mode represents multiple DB flags and support different database types:
safe, fast, fastest
Database-specific flags can be set instead.
LMDB flags (more than one may be specified):
nosync, nometasync, writemap, mapasync, nordahead
Examples:
$ oxen-blockchain-import --database lmdb#fastest
$ oxen-blockchain-import --database lmdb#nosync
$ oxen-blockchain-import --database lmdb#nosync,nometasync
