===============

||||
|
||||
Block file pruning
|
||||
Example header
|
||||
----------------------
|
||||
|
||||
This release supports running a fully validating node without maintaining a copy
|
||||
of the raw block and undo data on disk. To recap, there are four types of data
|
||||
related to the blockchain in the bitcoin system: the raw blocks as received over
|
||||
the network (blk???.dat), the undo data (rev???.dat), the block index and the
|
||||
UTXO set (both LevelDB databases). The databases are built from the raw data.
|
||||
Example content.
|
||||
|
||||
Block pruning allows Bitcoin Core to delete the raw block and undo data once
|
||||
it's been validated and used to build the databases. At that point, the raw data
|
||||
is used only to relay blocks to other nodes, to handle reorganizations, to look
|
||||
up old transactions (if -txindex is enabled or via the RPC/REST interfaces), or
|
||||
for rescanning the wallet. The block index continues to hold the metadata about
|
||||
all blocks in the blockchain.
|
||||
|
||||
The user specifies how much space to allot for block & undo files. The minimum
|
||||
allowed is 550MB. Note that this is in addition to whatever is required for the
|
||||
block index and UTXO databases. The minimum was chosen so that Bitcoin Core will
|
||||
be able to maintain at least 288 blocks on disk (two days worth of blocks at 10
|
||||
minutes per block). In rare instances it is possible that the amount of space
|
||||
used will exceed the pruning target in order to keep the required last 288
|
||||
blocks on disk.
|
||||
|
||||
Block pruning works during initial sync in the same way as during steady state,
|
||||
by deleting block files "as you go" whenever disk space is allocated. Thus, if
|
||||
the user specifies 550MB, once that level is reached the program will begin
|
||||
deleting the oldest block and undo files, while continuing to download the
|
||||
blockchain.
|
||||
|
||||
For now, block pruning disables block relay. In the future, nodes with block
|
||||
pruning will at a minimum relay "new" blocks, meaning blocks that extend their
|
||||
active chain.
|
||||
|
||||
Block pruning is currently incompatible with running a wallet due to the fact
|
||||
that block data is used for rescanning the wallet and importing keys or
|
||||
addresses (which require a rescan.) However, running the wallet with block
|
||||
pruning will be supported in the near future, subject to those limitations.
|
||||
|
||||
Block pruning is also incompatible with -txindex and will automatically disable
|
||||
it.
|
||||
|
||||
Once you have pruned blocks, going back to unpruned state requires
|
||||
re-downloading the entire blockchain. To do this, re-start the node with
|
||||
-reindex. Note also that any problem that would cause a user to reindex (e.g.,
|
||||
disk corruption) will cause a pruned node to redownload the entire blockchain.
|
||||
Finally, note that when a pruned node reindexes, it will delete any blk???.dat
|
||||
and rev???.dat files in the data directory prior to restarting the download.
|
||||
|
||||
To enable block pruning on the command line:
|
||||
|
||||
- `-prune=N`: where N is the number of MB to allot for raw block & undo data.
|
||||
|
||||
Modified RPC calls:
|
||||
|
||||
- `getblockchaininfo` now includes whether we are in pruned mode or not.
|
||||
- `getblock` will check if the block's data has been pruned and if so, return an
|
||||
error.
|
||||
- `getrawtransaction` will no longer be able to locate a transaction that has a
|
||||
UTXO but where its block file has been pruned.
|
||||
|
||||
Pruning is disabled by default.
|
||||
|
||||
Big endian support
|
||||
--------------------
|
||||
|
||||
Experimental support for big-endian CPU architectures was added in this
|
||||
release. This has been tested on at least MIPS and PPC hosts. The build
|
||||
system will automatically detect the endianness of the target.
|
||||
|
||||
Memory usage optimization
|
||||
--------------------------
|
||||
|
||||
There have been many changes in this release to reduce the default memory usage
|
||||
of a node, among which:
|
||||
|
||||
- Accurate UTXO cache size accounting (#6102); this makes the option `-dbcache`
|
||||
precise, where is did a gross underestimation of memory usage before
|
||||
- Reduce size of per-peer data structure (#6064 and others); this increases the
|
||||
number of connections that can be supported with the same amount of memory
|
||||
- Reduce the number of threads (#5964, #5679); lowers the amount of (esp.
|
||||
virtual) memory needed
|
||||
|
||||
Privacy: Disable wallet transaction broadcast
|
||||
----------------------------------------------
|
||||
|
||||
This release adds an option `-walletbroadcast=0` to prevent automatic
|
||||
transaction broadcast and rebroadcast (#5951). This option allows separating
|
||||
transaction submission from the node functionality.
|
||||
|
||||
Making use of this, third-party scripts can be written to take care of
|
||||
transaction (re)broadcast:
|
||||
|
||||
- Send the transaction as normal, either through RPC or the GUI
|
||||
- Retrieve the transaction data through RPC using `gettransaction` (NOT
|
||||
`getrawtransaction`). The `hex` field of the result will contain the raw
|
||||
hexadecimal representation of the transaction
|
||||
- The transaction can then be broadcasted through arbitrary mechanisms
|
||||
supported by the script
|
||||
|
||||
One such application is selective Tor usage, where the node runs on the normal
|
||||
internet but transactions are broadcasted over Tor.
|
||||
|
||||
Privacy: Stream isolation for Tor
|
||||
----------------------------------
|
||||
|
||||
This release adds functionality to create a new circuit for every peer
|
||||
connection, when the software is used with Tor. The new option,
|
||||
`-proxyrandomize`, is on by default.
|
||||
|
||||
When enabled, every outgoing connection will (potentially) go through a
|
||||
different exit node. That significantly reduces the chance to get unlucky and
|
||||
pick a single exit node that is either malicious, or widely banned from the P2P
|
||||
network. This improves connection reliability as well as privacy, especially
|
||||
for the initial connections.
|
||||
|
||||
**Important note:** If a non-Tor SOCKS5 proxy is configured that supports
|
||||
authentication, but doesn't require it, this change may cause it to reject
|
||||
connections. A user and password is sent where they weren't before. This setup
|
||||
is exceedingly rare, but in this case `-proxyrandomize=0` can be passed to
|
||||
disable the behavior.
