Bitcoin Core version 0.12.0 is now available from:
https://bitcoin.org/bin/bitcoin-core-0.12.0/
This is a new major version release, bringing new features and other improvements.
Please report bugs using the issue tracker at github:
https://github.com/bitcoin/bitcoin/issues
Upgrading and downgrading
How to Upgrade
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer (on Windows) or just copy over /Applications/Bitcoin-Qt (on Mac) or bitcoind/bitcoin-qt (on Linux).
Downgrade warning
Downgrade to a version < 0.10.0
Because release 0.10.0 and later makes use of headers-first synchronization and parallel block download (see further), the block files and databases are not backwards-compatible with pre-0.10 versions of Bitcoin Core or other software:
-
Blocks will be stored on disk out of order (in the order they are received, really), which makes it incompatible with some tools or other programs. Reindexing using earlier versions will also not work anymore as a result of this.
-
The block index database will now hold headers for which no block is stored on disk, which earlier versions won't support.
If you want to be able to downgrade smoothly, make a backup of your entire data directory. Without this your node will need start syncing (or importing from bootstrap.dat) anew afterwards. It is possible that the data from a completely synchronised 0.10 node may be usable in older versions as-is, but this is not supported and may break as soon as the older version attempts to reindex.
This does not affect wallet forward or backward compatibility.
Downgrade to a version < 0.12.0
Because release 0.12.0 and later will obfuscate the chainstate on every fresh sync or reindex, the chainstate is not backwards-compatible with pre-0.12 versions of Bitcoin Core or other software.
If you want to downgrade after you have done a reindex with 0.12.0 or later, you will need to reindex when you first start Bitcoin Core version 0.11 or earlier.
Notable changes
Signature validation using libsecp256k1
ECDSA signatures inside Bitcoin transactions now use validation using https://github.com/bitcoin/secp256k1 instead of OpenSSL.
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.
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.
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.
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 replace 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).
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
Transactions that do not pay the minimum relay fee, are called "free
transactions" or priority transactions. Previous versions of Bitcoin
Core would relay and mine priority transactions depending on their
setting of -limitfreerelay=<r>
(default: r=15
kB per minute) and
-blockprioritysize=<s>
(default: 50000
bytes of a block's
priority space).
Priority code is scheduled for removal in Bitcoin Core 0.13. In
Bitcoin Core 0.12, the default block priority size has been set to 0
and the priority calculation has been simplified to only include the
coin age of inputs that were in the blockchain at the time the transaction
was accepted into the mempool. In addition priority transactions are not
accepted to the mempool if mempool limiting has triggered a higher effective
minimum relay fee.
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 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=<n>
(or settxfee <n>
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=<m>
(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=<f>
(default: 0.0002
BTC/kB).
At all times, Bitcoin Core will cap fees at -maxtxfee=<x>
(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=<i>
, 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=<N>
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 unless there is a hard fork. 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.
NODE_BLOOM
service bit
Support for the NODE_BLOOM
service bit, as described in BIP
111, 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
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
<VirtualHost *:443>
SSLEngine On
SSLCertificateFile /etc/apache2/ssl/server.crt
SSLCertificateKeyFile /etc/apache2/ssl/server.key
<Location /bitcoinrpc>
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 <hash>"
# get the <hash> from the shell with: base64 <<< bitcoinrpc:<password>
</Location>
# Or, balance the load:
# ProxyPass / balancer://balancer_cluster_name
</VirtualHost>
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.
