Notable changes =============== -Signature validation using libsecp256k1 +Example item --------------------------------------- -ECDSA signatures inside Bitcoin transactions now use validation using -[https://github.com/bitcoin/secp256k1](libsecp256k1) instead of OpenSSL. +Example text. -Depending on the platform, this means a significant speedup for raw signature -validation speed. The advantage is largest on x86_64, where validation is over -five times faster. In practice, this translates to a raw reindexing and new -block validation times that are less than half of what it was before. - -Libsecp256k1 has undergone very extensive testing and validation. - -A side effect of this change is that libconsensus no longer depends on OpenSSL. - -Reduce upload traffic ---------------------- - -A major part of the outbound traffic is caused by serving historic blocks to -other nodes in initial block download state. - -It is now possible to reduce the total upload traffic via the `-maxuploadtarget` -parameter. This is *not* a hard limit but a threshold to minimize the outbound -traffic. When the limit is about to be reached, the uploaded data is cut by not -serving historic blocks (blocks older than one week). -Moreover, any SPV peer is disconnected when they request a filtered block. - -This option can be specified in MiB per day and is turned off by default -(`-maxuploadtarget=0`). -The recommended minimum is 144 * MAX_BLOCK_SIZE (currently 144MB) per day. - -Whitelisted peers will never be disconnected, although their traffic counts for -calculating the target. - -A more detailed documentation about keeping traffic low can be found in -[/doc/reduce-traffic.md](/doc/reduce-traffic.md). - -Direct headers announcement (BIP 130) -------------------------------------- - -Between compatible peers, [BIP 130] -(https://github.com/bitcoin/bips/blob/master/bip-0130.mediawiki) -direct headers announcement is used. This means that blocks are advertized by -announcing their headers directly, instead of just announcing the hash. In a -reorganization, all new headers are sent, instead of just the new tip. This -can often prevent an extra roundtrip before the actual block is downloaded. - -With this change, pruning nodes are now able to relay new blocks to compatible -peers. - -Memory pool limiting --------------------- - -Previous versions of Bitcoin Core had their mempool limited by checking -a transaction's fees against the node's minimum relay fee. There was no -upper bound on the size of the mempool and attackers could send a large -number of transactions paying just slighly more than the default minimum -relay fee to crash nodes with relatively low RAM. A temporary workaround -for previous versions of Bitcoin Core was to raise the default minimum -relay fee. - -Bitcoin Core 0.12 will have a strict maximum size on the mempool. The -default value is 300 MB and can be configured with the `-maxmempool` -parameter. Whenever a transaction would cause the mempool to exceed -its maximum size, the transaction that (along with in-mempool descendants) has -the lowest total feerate (as a package) will be evicted and the node's effective -minimum relay feerate will be increased to match this feerate plus the initial -minimum relay feerate. The initial minimum relay feerate is set to -1000 satoshis per kB. - -Bitcoin Core 0.12 also introduces new default policy limits on the length and -size of unconfirmed transaction chains that are allowed in the mempool -(generally limiting the length of unconfirmed chains to 25 transactions, with a -total size of 101 KB). These limits can be overriden using command line -arguments; see the extended help (`--help -help-debug`) for more information. - -Opt-in Replace-by-fee transactions ----------------------------------- - -It is now possible to replace transactions in the transaction memory pool of -Bitcoin Core 0.12 nodes. Bitcoin Core will only allow replacement of -transactions which have any of their inputs' `nSequence` number set to less -than `0xffffffff - 1`. Moreover, a replacement transaction may only be -accepted when it pays sufficient fee, as described in [BIP 125] -(https://github.com/bitcoin/bips/blob/master/bip-0125.mediawiki). - -Transaction replacement can be disabled with a new command line option, -`-mempoolreplacement=0`. Transactions signaling replacement under BIP125 will -still be allowed into the mempool in this configuration, but replacements will -be rejected. This option is intended for miners who want to continue the -transaction selection behavior of previous releases. - -The `-mempoolreplacement` option is *not recommended* for wallet users seeking -to avoid receipt of unconfirmed opt-in transactions, because this option does -not prevent transactions which are replaceable under BIP 125 from being accepted -(only subsequent replacements, which other nodes on the network that implement -BIP 125 are likely to relay and mine). Wallet users wishing to detect whether -a transaction is subject to replacement under BIP 125 should instead use the -updated RPC calls `gettransaction` and `listtransactions`, which now have an -additional field in the output indicating if a transaction is replaceable under -BIP125 ("bip125-replaceable"). - -Note that the wallet in Bitcoin Core 0.12 does not yet have support for -creating transactions that would be replaceable under BIP 125. - - -RPC: Random-cookie RPC authentication -------------------------------------- - -When no `-rpcpassword` is specified, the daemon now uses a special 'cookie' -file for authentication. This file is generated with random content when the -daemon starts, and deleted when it exits. Its contents are used as -authentication token. Read access to this file controls who can access through -RPC. By default it is stored in the data directory but its location can be -overridden with the option `-rpccookiefile`. - -This is similar to Tor's CookieAuthentication: see -https://www.torproject.org/docs/tor-manual.html.en - -This allows running bitcoind without having to do any manual configuration. - -Relay: Any sequence of pushdatas in OP_RETURN outputs now allowed ------------------------------------------------------------------ - -Previously OP_RETURN outputs with a payload were only relayed and mined if they -had a single pushdata. This restriction has been lifted to allow any -combination of data pushes and numeric constant opcodes (OP_1 to OP_16) after -the OP_RETURN. The limit on OP_RETURN output size is now applied to the entire -serialized scriptPubKey, 83 bytes by default. (the previous 80 byte default plus -three bytes overhead) - -Relay and Mining: Priority transactions ---------------------------------------- - -Bitcoin Core has a heuristic 'priority' based on coin value and age. This -calculation is used for relaying of transactions which do not pay the -minimum relay fee, and can be used as an alternative way of sorting -transactions for mined blocks. Bitcoin Core will relay transactions with -insufficient fees depending on the setting of `-limitfreerelay=` (default: -`r=15` kB per minute) and `-blockprioritysize=`. - -In Bitcoin Core 0.12, when mempool limit has been reached a higher minimum -relay fee takes effect to limit memory usage. Transactions which do not meet -this higher effective minimum relay fee will not be relayed or mined even if -they rank highly according to the priority heuristic. - -The mining of transactions based on their priority is also now disabled by -default. To re-enable it, simply set `-blockprioritysize=` where is the size -in bytes of your blocks to reserve for these transactions. The old default was -50k, so to retain approximately the same policy, you would set -`-blockprioritysize=50000`. - -Additionally, as a result of computational simplifications, the priority value -used for transactions received with unconfirmed inputs is lower than in prior -versions due to avoiding recomputing the amounts as input transactions confirm. - -External miner policy set via the `prioritisetransaction` RPC to rank -transactions already in the mempool continues to work as it has previously. -Note, however, that if mining priority transactions is left disabled, the -priority delta will be ignored and only the fee metric will be effective. - -This internal automatic prioritization handling is being considered for removal -entirely in Bitcoin Core 0.13, and it is at this time undecided whether the -more accurate priority calculation for chained unconfirmed transactions will be -restored. Community direction on this topic is particularly requested to help -set project priorities. - -Automatically use Tor hidden services -------------------------------------- - -Starting with Tor version 0.2.7.1 it is possible, through Tor's control socket -API, to create and destroy 'ephemeral' hidden services programmatically. -Bitcoin Core has been updated to make use of this. - -This means that if Tor is running (and proper authorization is available), -Bitcoin Core automatically creates a hidden service to listen on, without -manual configuration. Bitcoin Core will also use Tor automatically to connect -to other .onion nodes if the control socket can be successfully opened. This -will positively affect the number of available .onion nodes and their usage. - -This new feature is enabled by default if Bitcoin Core is listening, and -a connection to Tor can be made. It can be configured with the `-listenonion`, -`-torcontrol` and `-torpassword` settings. To show verbose debugging -information, pass `-debug=tor`. - -Notifications through ZMQ -------------------------- - -Bitcoind can now (optionally) asynchronously notify clients through a -ZMQ-based PUB socket of the arrival of new transactions and blocks. -This feature requires installation of the ZMQ C API library 4.x and -configuring its use through the command line or configuration file. -Please see [docs/zmq.md](/doc/zmq.md) for details of operation. - -Wallet: Transaction fees ------------------------- - -Various improvements have been made to how the wallet calculates -transaction fees. - -Users can decide to pay a predefined fee rate by setting `-paytxfee=` -(or `settxfee ` rpc during runtime). A value of `n=0` signals Bitcoin -Core to use floating fees. By default, Bitcoin Core will use floating -fees. - -Based on past transaction data, floating fees approximate the fees -required to get into the `m`th block from now. This is configurable -with `-txconfirmtarget=` (default: `2`). - -Sometimes, it is not possible to give good estimates, or an estimate -at all. Therefore, a fallback value can be set with `-fallbackfee=` -(default: `0.0002` BTC/kB). - -At all times, Bitcoin Core will cap fees at `-maxtxfee=` (default: -0.10) BTC. -Furthermore, Bitcoin Core will never create transactions smaller than -the current minimum relay fee. -Finally, a user can set the minimum fee rate for all transactions with -`-mintxfee=`, which defaults to 1000 satoshis per kB. - -Wallet: Negative confirmations and conflict detection ------------------------------------------------------ - -The wallet will now report a negative number for confirmations that indicates -how deep in the block chain the conflict is found. For example, if a transaction -A has 5 confirmations and spends the same input as a wallet transaction B, B -will be reported as having -5 confirmations. If another wallet transaction C -spends an output from B, it will also be reported as having -5 confirmations. -To detect conflicts with historical transactions in the chain a one-time -`-rescan` may be needed. - -Unlike earlier versions, unconfirmed but non-conflicting transactions will never -get a negative confirmation count. They are not treated as spendable unless -they're coming from ourself (change) and accepted into our local mempool, -however. The new "trusted" field in the `listtransactions` RPC output -indicates whether outputs of an unconfirmed transaction are considered -spendable. - -Wallet: Merkle branches removed -------------------------------- - -Previously, every wallet transaction stored a Merkle branch to prove its -presence in blocks. This wasn't being used for more than an expensive -sanity check. Since 0.12, these are no longer stored. When loading a -0.12 wallet into an older version, it will automatically rescan to avoid -failed checks. - -Wallet: Pruning ---------------- - -With 0.12 it is possible to use wallet functionality in pruned mode. -This can reduce the disk usage from currently around 60 GB to -around 2 GB. - -However, rescans as well as the RPCs `importwallet`, `importaddress`, -`importprivkey` are disabled. - -To enable block pruning set `prune=` on the command line or in -`bitcoin.conf`, where `N` is the number of MiB to allot for -raw block & undo data. - -A value of 0 disables pruning. The minimal value above 0 is 550. Your -wallet is as secure with high values as it is with low ones. Higher -values merely ensure that your node will not shut down upon blockchain -reorganizations of more than 2 days - which are unlikely to happen in -practice. In future releases, a higher value may also help the network -as a whole: stored blocks could be served to other nodes. - -For further information about pruning, you may also consult the [release -notes of v0.11.0](https://github.com/bitcoin/bitcoin/blob/v0.11.0/doc/release-notes.md#block-file-pruning). - -`NODE_BLOOM` service bit ------------------------- - -Support for the `NODE_BLOOM` service bit, as described in [BIP -111](https://github.com/bitcoin/bips/blob/master/bip-0111.mediawiki), has been -added to the P2P protocol code. - -BIP 111 defines a service bit to allow peers to advertise that they support -bloom filters (such as used by SPV clients) explicitly. It also bumps the protocol -version to allow peers to identify old nodes which allow bloom filtering of the -connection despite lacking the new service bit. - -In this version, it is only enforced for peers that send protocol versions -`>=70011`. For the next major version it is planned that this restriction will be -removed. It is recommended to update SPV clients to check for the `NODE_BLOOM` -service bit for nodes that report versions newer than 70011. - -Option parsing behavior ------------------------ - -Command line options are now parsed strictly in the order in which they are -specified. It used to be the case that `-X -noX` ends up, unintuitively, with X -set, as `-X` had precedence over `-noX`. This is no longer the case. Like for -other software, the last specified value for an option will hold. - -RPC: Low-level API changes --------------------------- - -- Monetary amounts can be provided as strings. This means that for example the - argument to sendtoaddress can be "0.0001" instead of 0.0001. This can be an - advantage if a JSON library insists on using a lossy floating point type for - numbers, which would be dangerous for monetary amounts. - -* The `asm` property of each scriptSig now contains the decoded signature hash - type for each signature that provides a valid defined hash type. - -* OP_NOP2 has been renamed to OP_CHECKLOCKTIMEVERIFY by [BIP 65](https://github.com/bitcoin/bips/blob/master/bip-0065.mediawiki) - -The following items contain assembly representations of scriptSig signatures -and are affected by this change: - -- RPC `getrawtransaction` -- RPC `decoderawtransaction` -- RPC `decodescript` -- REST `/rest/tx/` (JSON format) -- REST `/rest/block/` (JSON format when including extended tx details) -- `bitcoin-tx -json` - -For example, the `scriptSig.asm` property of a transaction input that -previously showed an assembly representation of: - - 304502207fa7a6d1e0ee81132a269ad84e68d695483745cde8b541e3bf630749894e342a022100c1f7ab20e13e22fb95281a870f3dcf38d782e53023ee313d741ad0cfbc0c509001 400000 OP_NOP2 - -now shows as: - - 304502207fa7a6d1e0ee81132a269ad84e68d695483745cde8b541e3bf630749894e342a022100c1f7ab20e13e22fb95281a870f3dcf38d782e53023ee313d741ad0cfbc0c5090[ALL] 400000 OP_CHECKLOCKTIMEVERIFY - -Note that the output of the RPC `decodescript` did not change because it is -configured specifically to process scriptPubKey and not scriptSig scripts. - -RPC: SSL support dropped ------------------------- - -SSL support for RPC, previously enabled by the option `rpcssl` has been dropped -from both the client and the server. This was done in preparation for removing -the dependency on OpenSSL for the daemon completely. - -Trying to use `rpcssl` will result in an error: - - Error: SSL mode for RPC (-rpcssl) is no longer supported. - -If you are one of the few people that relies on this feature, a flexible -migration path is to use `stunnel`. This is an utility that can tunnel -arbitrary TCP connections inside SSL. On e.g. Ubuntu it can be installed with: - - sudo apt-get install stunnel4 - -Then, to tunnel a SSL connection on 28332 to a RPC server bound on localhost on port 18332 do: - - stunnel -d 28332 -r 127.0.0.1:18332 -p stunnel.pem -P '' - -It can also be set up system-wide in inetd style. - -Another way to re-attain SSL would be to setup a httpd reverse proxy. This solution -would allow the use of different authentication, loadbalancing, on-the-fly compression and -caching. A sample config for apache2 could look like: - - Listen 443 - - NameVirtualHost *:443 - - - SSLEngine On - SSLCertificateFile /etc/apache2/ssl/server.crt - SSLCertificateKeyFile /etc/apache2/ssl/server.key - - - ProxyPass http://127.0.0.1:8332/ - ProxyPassReverse http://127.0.0.1:8332/ - # optional enable digest auth - # AuthType Digest - # ... - - # optional bypass bitcoind rpc basic auth - # RequestHeader set Authorization "Basic " - # get the from the shell with: base64 <<< bitcoinrpc: - - - # Or, balance the load: - # ProxyPass / balancer://balancer_cluster_name - - - -Mining Code Changes -------------------- - -The mining code in 0.12 has been optimized to be significantly faster and use less -memory. As part of these changes, consensus critical calculations are cached on a -transaction's acceptance into the mempool and the mining code now relies on the -consistency of the mempool to assemble blocks. However all blocks are still tested -for validity after assembly. - -Other P2P Changes ------------------ - -The list of banned peers is now stored on disk rather than in memory. -Restarting bitcoind will no longer clear out the list of banned peers; instead -a new RPC call (`clearbanned`) can be used to manually clear the list. The new -`setban` RPC call can also be used to manually ban or unban a peer. - -0.12.0 Change log +0.12.1 Change log ================= Detailed release notes follow.
