release-notes-0.12.0.md
1 Bitcoin Core version 0.12.0 is now available from: 2 3 <https://bitcoin.org/bin/bitcoin-core-0.12.0/> 4 5 This is a new major version release, bringing new features and other improvements. 6 7 Please report bugs using the issue tracker at github: 8 9 <https://github.com/bitcoin/bitcoin/issues> 10 11 Upgrading and downgrading 12 ========================= 13 14 How to Upgrade 15 -------------- 16 17 If you are running an older version, shut it down. Wait until it has completely 18 shut down (which might take a few minutes for older versions), then run the 19 installer (on Windows) or just copy over /Applications/Bitcoin-Qt (on Mac) or 20 bitcoind/bitcoin-qt (on Linux). 21 22 Downgrade warning 23 ----------------- 24 25 ### Downgrade to a version < 0.10.0 26 27 Because release 0.10.0 and later makes use of headers-first synchronization and 28 parallel block download (see further), the block files and databases are not 29 backwards-compatible with pre-0.10 versions of Bitcoin Core or other software: 30 31 * Blocks will be stored on disk out of order (in the order they are 32 received, really), which makes it incompatible with some tools or 33 other programs. Reindexing using earlier versions will also not work 34 anymore as a result of this. 35 36 * The block index database will now hold headers for which no block is 37 stored on disk, which earlier versions won't support. 38 39 If you want to be able to downgrade smoothly, make a backup of your entire data 40 directory. Without this your node will need start syncing (or importing from 41 bootstrap.dat) anew afterwards. It is possible that the data from a completely 42 synchronised 0.10 node may be usable in older versions as-is, but this is not 43 supported and may break as soon as the older version attempts to reindex. 44 45 This does not affect wallet forward or backward compatibility. 46 47 ### Downgrade to a version < 0.12.0 48 49 Because release 0.12.0 and later will obfuscate the chainstate on every 50 fresh sync or reindex, the chainstate is not backwards-compatible with 51 pre-0.12 versions of Bitcoin Core or other software. 52 53 If you want to downgrade after you have done a reindex with 0.12.0 or later, 54 you will need to reindex when you first start Bitcoin Core version 0.11 or 55 earlier. 56 57 Notable changes 58 =============== 59 60 Signature validation using libsecp256k1 61 --------------------------------------- 62 63 ECDSA signatures inside Bitcoin transactions now use validation using 64 [libsecp256k1](https://github.com/bitcoin-core/secp256k1) instead of OpenSSL. 65 66 Depending on the platform, this means a significant speedup for raw signature 67 validation speed. The advantage is largest on x86_64, where validation is over 68 five times faster. In practice, this translates to a raw reindexing and new 69 block validation times that are less than half of what it was before. 70 71 Libsecp256k1 has undergone very extensive testing and validation. 72 73 A side effect of this change is that libconsensus no longer depends on OpenSSL. 74 75 Reduce upload traffic 76 --------------------- 77 78 A major part of the outbound traffic is caused by serving historic blocks to 79 other nodes in initial block download state. 80 81 It is now possible to reduce the total upload traffic via the `-maxuploadtarget` 82 parameter. This is *not* a hard limit but a threshold to minimize the outbound 83 traffic. When the limit is about to be reached, the uploaded data is cut by not 84 serving historic blocks (blocks older than one week). 85 Moreover, any SPV peer is disconnected when they request a filtered block. 86 87 This option can be specified in MiB per day and is turned off by default 88 (`-maxuploadtarget=0`). 89 The recommended minimum is 144 * MAX_BLOCK_SIZE (currently 144MB) per day. 90 91 Whitelisted peers will never be disconnected, although their traffic counts for 92 calculating the target. 93 94 A more detailed documentation about keeping traffic low can be found in 95 [/doc/reduce-traffic.md](/doc/reduce-traffic.md). 96 97 Direct headers announcement (BIP 130) 98 ------------------------------------- 99 100 Between compatible peers, [BIP 130] 101 (https://github.com/bitcoin/bips/blob/master/bip-0130.mediawiki) 102 direct headers announcement is used. This means that blocks are advertised by 103 announcing their headers directly, instead of just announcing the hash. In a 104 reorganization, all new headers are sent, instead of just the new tip. This 105 can often prevent an extra roundtrip before the actual block is downloaded. 106 107 Memory pool limiting 108 -------------------- 109 110 Previous versions of Bitcoin Core had their mempool limited by checking 111 a transaction's fees against the node's minimum relay fee. There was no 112 upper bound on the size of the mempool and attackers could send a large 113 number of transactions paying just slighly more than the default minimum 114 relay fee to crash nodes with relatively low RAM. A temporary workaround 115 for previous versions of Bitcoin Core was to raise the default minimum 116 relay fee. 117 118 Bitcoin Core 0.12 will have a strict maximum size on the mempool. The 119 default value is 300 MB and can be configured with the `-maxmempool` 120 parameter. Whenever a transaction would cause the mempool to exceed 121 its maximum size, the transaction that (along with in-mempool descendants) has 122 the lowest total feerate (as a package) will be evicted and the node's effective 123 minimum relay feerate will be increased to match this feerate plus the initial 124 minimum relay feerate. The initial minimum relay feerate is set to 125 1000 satoshis per kB. 126 127 Bitcoin Core 0.12 also introduces new default policy limits on the length and 128 size of unconfirmed transaction chains that are allowed in the mempool 129 (generally limiting the length of unconfirmed chains to 25 transactions, with a 130 total size of 101 KB). These limits can be overridden using command line 131 arguments; see the extended help (`--help -help-debug`) for more information. 132 133 Opt-in Replace-by-fee transactions 134 ---------------------------------- 135 136 It is now possible to replace transactions in the transaction memory pool of 137 Bitcoin Core 0.12 nodes. Bitcoin Core will only allow replacement of 138 transactions which have any of their inputs' `nSequence` number set to less 139 than `0xffffffff - 1`. Moreover, a replacement transaction may only be 140 accepted when it pays sufficient fee, as described in [BIP 125] 141 (https://github.com/bitcoin/bips/blob/master/bip-0125.mediawiki). 142 143 Transaction replacement can be disabled with a new command line option, 144 `-mempoolreplacement=0`. Transactions signaling replacement under BIP125 will 145 still be allowed into the mempool in this configuration, but replacements will 146 be rejected. This option is intended for miners who want to continue the 147 transaction selection behavior of previous releases. 148 149 The `-mempoolreplacement` option is *not recommended* for wallet users seeking 150 to avoid receipt of unconfirmed opt-in transactions, because this option does 151 not prevent transactions which are replaceable under BIP 125 from being accepted 152 (only subsequent replacements, which other nodes on the network that implement 153 BIP 125 are likely to relay and mine). Wallet users wishing to detect whether 154 a transaction is subject to replacement under BIP 125 should instead use the 155 updated RPC calls `gettransaction` and `listtransactions`, which now have an 156 additional field in the output indicating if a transaction is replaceable under 157 BIP125 ("bip125-replaceable"). 158 159 Note that the wallet in Bitcoin Core 0.12 does not yet have support for 160 creating transactions that would be replaceable under BIP 125. 161 162 163 RPC: Random-cookie RPC authentication 164 ------------------------------------- 165 166 When no `-rpcpassword` is specified, the daemon now uses a special 'cookie' 167 file for authentication. This file is generated with random content when the 168 daemon starts, and deleted when it exits. Its contents are used as 169 authentication token. Read access to this file controls who can access through 170 RPC. By default it is stored in the data directory but its location can be 171 overridden with the option `-rpccookiefile`. 172 173 This is similar to Tor's CookieAuthentication: see 174 https://www.torproject.org/docs/tor-manual.html.en 175 176 This allows running bitcoind without having to do any manual configuration. 177 178 Relay: Any sequence of pushdatas in OP_RETURN outputs now allowed 179 ----------------------------------------------------------------- 180 181 Previously OP_RETURN outputs with a payload were only relayed and mined if they 182 had a single pushdata. This restriction has been lifted to allow any 183 combination of data pushes and numeric constant opcodes (OP_1 to OP_16) after 184 the OP_RETURN. The limit on OP_RETURN output size is now applied to the entire 185 serialized scriptPubKey, 83 bytes by default. (the previous 80 byte default plus 186 three bytes overhead) 187 188 Relay: New and only new blocks relayed when pruning 189 --------------------------------------------------- 190 191 When running in pruned mode, the client will now relay new blocks. When 192 responding to the `getblocks` message, only hashes of blocks that are on disk 193 and are likely to remain there for some reasonable time window (1 hour) will be 194 returned (previously all relevant hashes were returned). 195 196 Relay and Mining: Priority transactions 197 --------------------------------------- 198 199 Bitcoin Core has a heuristic 'priority' based on coin value and age. This 200 calculation is used for relaying of transactions which do not pay the 201 minimum relay fee, and can be used as an alternative way of sorting 202 transactions for mined blocks. Bitcoin Core will relay transactions with 203 insufficient fees depending on the setting of `-limitfreerelay=<r>` (default: 204 `r=15` kB per minute) and `-blockprioritysize=<s>`. 205 206 In Bitcoin Core 0.12, when mempool limit has been reached a higher minimum 207 relay fee takes effect to limit memory usage. Transactions which do not meet 208 this higher effective minimum relay fee will not be relayed or mined even if 209 they rank highly according to the priority heuristic. 210 211 The mining of transactions based on their priority is also now disabled by 212 default. To re-enable it, simply set `-blockprioritysize=<n>` where is the size 213 in bytes of your blocks to reserve for these transactions. The old default was 214 50k, so to retain approximately the same policy, you would set 215 `-blockprioritysize=50000`. 216 217 Additionally, as a result of computational simplifications, the priority value 218 used for transactions received with unconfirmed inputs is lower than in prior 219 versions due to avoiding recomputing the amounts as input transactions confirm. 220 221 External miner policy set via the `prioritisetransaction` RPC to rank 222 transactions already in the mempool continues to work as it has previously. 223 Note, however, that if mining priority transactions is left disabled, the 224 priority delta will be ignored and only the fee metric will be effective. 225 226 This internal automatic prioritization handling is being considered for removal 227 entirely in Bitcoin Core 0.13, and it is at this time undecided whether the 228 more accurate priority calculation for chained unconfirmed transactions will be 229 restored. Community direction on this topic is particularly requested to help 230 set project priorities. 231 232 Automatically use Tor hidden services 233 ------------------------------------- 234 235 Starting with Tor version 0.2.7.1 it is possible, through Tor's control socket 236 API, to create and destroy 'ephemeral' hidden services programmatically. 237 Bitcoin Core has been updated to make use of this. 238 239 This means that if Tor is running (and proper authorization is available), 240 Bitcoin Core automatically creates a hidden service to listen on, without 241 manual configuration. Bitcoin Core will also use Tor automatically to connect 242 to other .onion nodes if the control socket can be successfully opened. This 243 will positively affect the number of available .onion nodes and their usage. 244 245 This new feature is enabled by default if Bitcoin Core is listening, and 246 a connection to Tor can be made. It can be configured with the `-listenonion`, 247 `-torcontrol` and `-torpassword` settings. To show verbose debugging 248 information, pass `-debug=tor`. 249 250 Notifications through ZMQ 251 ------------------------- 252 253 Bitcoind can now (optionally) asynchronously notify clients through a 254 ZMQ-based PUB socket of the arrival of new transactions and blocks. 255 This feature requires installation of the ZMQ C API library 4.x and 256 configuring its use through the command line or configuration file. 257 Please see [docs/zmq.md](/doc/zmq.md) for details of operation. 258 259 Wallet: Transaction fees 260 ------------------------ 261 262 Various improvements have been made to how the wallet calculates 263 transaction fees. 264 265 Users can decide to pay a predefined fee rate by setting `-paytxfee=<n>` 266 (or `settxfee <n>` rpc during runtime). A value of `n=0` signals Bitcoin 267 Core to use floating fees. By default, Bitcoin Core will use floating 268 fees. 269 270 Based on past transaction data, floating fees approximate the fees 271 required to get into the `m`th block from now. This is configurable 272 with `-txconfirmtarget=<m>` (default: `2`). 273 274 Sometimes, it is not possible to give good estimates, or an estimate 275 at all. Therefore, a fallback value can be set with `-fallbackfee=<f>` 276 (default: `0.0002` BTC/kB). 277 278 At all times, Bitcoin Core will cap fees at `-maxtxfee=<x>` (default: 279 0.10) BTC. 280 Furthermore, Bitcoin Core will never create transactions paying less than 281 the current minimum relay fee. 282 Finally, a user can set the minimum fee rate for all transactions with 283 `-mintxfee=<i>`, which defaults to 1000 satoshis per kB. 284 285 Wallet: Negative confirmations and conflict detection 286 ----------------------------------------------------- 287 288 The wallet will now report a negative number for confirmations that indicates 289 how deep in the block chain the conflict is found. For example, if a transaction 290 A has 5 confirmations and spends the same input as a wallet transaction B, B 291 will be reported as having -5 confirmations. If another wallet transaction C 292 spends an output from B, it will also be reported as having -5 confirmations. 293 To detect conflicts with historical transactions in the chain a one-time 294 `-rescan` may be needed. 295 296 Unlike earlier versions, unconfirmed but non-conflicting transactions will never 297 get a negative confirmation count. They are not treated as spendable unless 298 they're coming from ourself (change) and accepted into our local mempool, 299 however. The new "trusted" field in the `listtransactions` RPC output 300 indicates whether outputs of an unconfirmed transaction are considered 301 spendable. 302 303 Wallet: Merkle branches removed 304 ------------------------------- 305 306 Previously, every wallet transaction stored a Merkle branch to prove its 307 presence in blocks. This wasn't being used for more than an expensive 308 sanity check. Since 0.12, these are no longer stored. When loading a 309 0.12 wallet into an older version, it will automatically rescan to avoid 310 failed checks. 311 312 Wallet: Pruning 313 --------------- 314 315 With 0.12 it is possible to use wallet functionality in pruned mode. 316 This can reduce the disk usage from currently around 60 GB to 317 around 2 GB. 318 319 However, rescans as well as the RPCs `importwallet`, `importaddress`, 320 `importprivkey` are disabled. 321 322 To enable block pruning set `prune=<N>` on the command line or in 323 `bitcoin.conf`, where `N` is the number of MiB to allot for 324 raw block & undo data. 325 326 A value of 0 disables pruning. The minimal value above 0 is 550. Your 327 wallet is as secure with high values as it is with low ones. Higher 328 values merely ensure that your node will not shut down upon blockchain 329 reorganizations of more than 2 days - which are unlikely to happen in 330 practice. In future releases, a higher value may also help the network 331 as a whole: stored blocks could be served to other nodes. 332 333 For further information about pruning, you may also consult the [release 334 notes of v0.11.0](https://github.com/bitcoin/bitcoin/blob/v0.11.0/doc/release-notes.md#block-file-pruning). 335 336 `NODE_BLOOM` service bit 337 ------------------------ 338 339 Support for the `NODE_BLOOM` service bit, as described in [BIP 340 111](https://github.com/bitcoin/bips/blob/master/bip-0111.mediawiki), has been 341 added to the P2P protocol code. 342 343 BIP 111 defines a service bit to allow peers to advertise that they support 344 bloom filters (such as used by SPV clients) explicitly. It also bumps the protocol 345 version to allow peers to identify old nodes which allow bloom filtering of the 346 connection despite lacking the new service bit. 347 348 In this version, it is only enforced for peers that send protocol versions 349 `>=70011`. For the next major version it is planned that this restriction will be 350 removed. It is recommended to update SPV clients to check for the `NODE_BLOOM` 351 service bit for nodes that report versions newer than 70011. 352 353 Option parsing behavior 354 ----------------------- 355 356 Command line options are now parsed strictly in the order in which they are 357 specified. It used to be the case that `-X -noX` ends up, unintuitively, with X 358 set, as `-X` had precedence over `-noX`. This is no longer the case. Like for 359 other software, the last specified value for an option will hold. 360 361 RPC: Low-level API changes 362 -------------------------- 363 364 - Monetary amounts can be provided as strings. This means that for example the 365 argument to sendtoaddress can be "0.0001" instead of 0.0001. This can be an 366 advantage if a JSON library insists on using a lossy floating point type for 367 numbers, which would be dangerous for monetary amounts. 368 369 * The `asm` property of each scriptSig now contains the decoded signature hash 370 type for each signature that provides a valid defined hash type. 371 372 * OP_NOP2 has been renamed to OP_CHECKLOCKTIMEVERIFY by [BIP 65](https://github.com/bitcoin/bips/blob/master/bip-0065.mediawiki) 373 374 The following items contain assembly representations of scriptSig signatures 375 and are affected by this change: 376 377 - RPC `getrawtransaction` 378 - RPC `decoderawtransaction` 379 - RPC `decodescript` 380 - REST `/rest/tx/` (JSON format) 381 - REST `/rest/block/` (JSON format when including extended tx details) 382 - `bitcoin-tx -json` 383 384 For example, the `scriptSig.asm` property of a transaction input that 385 previously showed an assembly representation of: 386 387 304502207fa7a6d1e0ee81132a269ad84e68d695483745cde8b541e3bf630749894e342a022100c1f7ab20e13e22fb95281a870f3dcf38d782e53023ee313d741ad0cfbc0c509001 400000 OP_NOP2 388 389 now shows as: 390 391 304502207fa7a6d1e0ee81132a269ad84e68d695483745cde8b541e3bf630749894e342a022100c1f7ab20e13e22fb95281a870f3dcf38d782e53023ee313d741ad0cfbc0c5090[ALL] 400000 OP_CHECKLOCKTIMEVERIFY 392 393 Note that the output of the RPC `decodescript` did not change because it is 394 configured specifically to process scriptPubKey and not scriptSig scripts. 395 396 RPC: SSL support dropped 397 ------------------------ 398 399 SSL support for RPC, previously enabled by the option `rpcssl` has been dropped 400 from both the client and the server. This was done in preparation for removing 401 the dependency on OpenSSL for the daemon completely. 402 403 Trying to use `rpcssl` will result in an error: 404 405 Error: SSL mode for RPC (-rpcssl) is no longer supported. 406 407 If you are one of the few people that relies on this feature, a flexible 408 migration path is to use `stunnel`. This is an utility that can tunnel 409 arbitrary TCP connections inside SSL. On e.g. Ubuntu it can be installed with: 410 411 sudo apt-get install stunnel4 412 413 Then, to tunnel a SSL connection on 28332 to a RPC server bound on localhost on port 18332 do: 414 415 stunnel -d 28332 -r 127.0.0.1:18332 -p stunnel.pem -P '' 416 417 It can also be set up system-wide in inetd style. 418 419 Another way to re-attain SSL would be to setup a httpd reverse proxy. This solution 420 would allow the use of different authentication, loadbalancing, on-the-fly compression and 421 caching. A sample config for apache2 could look like: 422 423 Listen 443 424 425 NameVirtualHost *:443 426 <VirtualHost *:443> 427 428 SSLEngine On 429 SSLCertificateFile /etc/apache2/ssl/server.crt 430 SSLCertificateKeyFile /etc/apache2/ssl/server.key 431 432 <Location /bitcoinrpc> 433 ProxyPass http://127.0.0.1:8332/ 434 ProxyPassReverse http://127.0.0.1:8332/ 435 # optional enable digest auth 436 # AuthType Digest 437 # ... 438 439 # optional bypass bitcoind rpc basic auth 440 # RequestHeader set Authorization "Basic <hash>" 441 # get the <hash> from the shell with: base64 <<< bitcoinrpc:<password> 442 </Location> 443 444 # Or, balance the load: 445 # ProxyPass / balancer://balancer_cluster_name 446 447 </VirtualHost> 448 449 Mining Code Changes 450 ------------------- 451 452 The mining code in 0.12 has been optimized to be significantly faster and use less 453 memory. As part of these changes, consensus critical calculations are cached on a 454 transaction's acceptance into the mempool and the mining code now relies on the 455 consistency of the mempool to assemble blocks. However all blocks are still tested 456 for validity after assembly. 457 458 Other P2P Changes 459 ----------------- 460 461 The list of banned peers is now stored on disk rather than in memory. 462 Restarting bitcoind will no longer clear out the list of banned peers; instead 463 a new RPC call (`clearbanned`) can be used to manually clear the list. The new 464 `setban` RPC call can also be used to manually ban or unban a peer. 465 466 0.12.0 Change log 467 ================= 468 469 Detailed release notes follow.
