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. - -0.11.0 Change log +0.12.0 Change log ================= Detailed release notes follow.
