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).
|
||||
|
||||
Downgrading warning
|
||||
---------------------
|
||||
|
||||
Because release 0.10.0 makes use of headers-first synchronization and parallel
|
||||
block download (see further), the block files and databases are not
|
||||
backwards-compatible with older 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.
|
||||
|
||||
|
||||
Notable changes
|
||||
===============
|
||||
|
||||
Faster synchronization
|
||||
----------------------
|
||||
|
||||
Bitcoin Core now uses 'headers-first synchronization'. This means that we first
|
||||
ask peers for block headers (a total of 27 megabytes, as of December 2014) and
|
||||
validate those. In a second stage, when the headers have been discovered, we
|
||||
download the blocks. However, as we already know about the whole chain in
|
||||
advance, the blocks can be downloaded in parallel from all available peers.
|
||||
|
||||
In practice, this means a much faster and more robust synchronization. On
|
||||
recent hardware with a decent network link, it can be as little as 3 hours
|
||||
for an initial full synchronization. You may notice a slower progress in the
|
||||
very first few minutes, when headers are still being fetched and verified, but
|
||||
it should gain speed afterwards.
|
||||
|
||||
A few RPCs were added/updated as a result of this:
|
||||
- `getblockchaininfo` now returns the number of validated headers in addition to
|
||||
the number of validated blocks.
|
||||
- `getpeerinfo` lists both the number of blocks and headers we know we have in
|
||||
common with each peer. While synchronizing, the heights of the blocks that we
|
||||
have requested from peers (but haven't received yet) are also listed as
|
||||
'inflight'.
|
||||
- A new RPC `getchaintips` lists all known branches of the block chain,
|
||||
including those we only have headers for.
|
||||
|
||||
Transaction fee changes
|
||||
-----------------------
|
||||
|
||||
This release automatically estimates how high a transaction fee (or how
|
||||
high a priority) transactions require to be confirmed quickly. The default
|
||||
settings will create transactions that confirm quickly; see the new
|
||||
'txconfirmtarget' setting to control the tradeoff between fees and
|
||||
confirmation times. Fees are added by default unless the 'sendfreetransactions'
|
||||
setting is enabled.
|
||||
|
||||
Prior releases used hard-coded fees (and priorities), and would
|
||||
sometimes create transactions that took a very long time to confirm.
|
||||
|
||||
Statistics used to estimate fees and priorities are saved in the
|
||||
data directory in the `fee_estimates.dat` file just before
|
||||
program shutdown, and are read in at startup.
|
||||
|
||||
New command line options for transaction fee changes:
|
||||
- `-txconfirmtarget=n` : create transactions that have enough fees (or priority)
|
||||
so they are likely to begin confirmation within n blocks (default: 1). This setting
|
||||
is over-ridden by the -paytxfee option.
|
||||
- `-sendfreetransactions` : Send transactions as zero-fee transactions if possible
|
||||
(default: 0)
|
||||
|
||||
New RPC commands for fee estimation:
|
||||
- `estimatefee nblocks` : Returns approximate fee-per-1,000-bytes needed for
|
||||
a transaction to begin confirmation within nblocks. Returns -1 if not enough
|
||||
transactions have been observed to compute a good estimate.
|
||||
- `estimatepriority nblocks` : Returns approximate priority needed for
|
||||
a zero-fee transaction to begin confirmation within nblocks. Returns -1 if not
|
||||
enough free transactions have been observed to compute a good
|
||||
estimate.
|
||||
|
||||
RPC access control changes
|
||||
--------------------------
|
||||
|
||||
Subnet matching for the purpose of access control is now done
|
||||
by matching the binary network address, instead of with string wildcard matching.
|
||||
For the user this means that `-rpcallowip` takes a subnet specification, which can be
|
||||
|
||||
- a single IP address (e.g. `1.2.3.4` or `fe80::0012:3456:789a:bcde`)
|
||||
- a network/CIDR (e.g. `1.2.3.0/24` or `fe80::0000/64`)
|
||||
- a network/netmask (e.g. `1.2.3.4/255.255.255.0` or `fe80::0012:3456:789a:bcde/ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff`)
|
||||
|
||||
An arbitrary number of `-rpcallow` arguments can be given. An incoming connection will be accepted if its origin address
|
||||
matches one of them.
|
||||
|
||||
For example:
|
||||
|
||||
| 0.9.x and before | 0.10.x |
|
||||
|--------------------------------------------|---------------------------------------|
|
||||
| `-rpcallowip=192.168.1.1` | `-rpcallowip=192.168.1.1` (unchanged) |
|
||||
| `-rpcallowip=192.168.1.*` | `-rpcallowip=192.168.1.0/24` |
|
||||
| `-rpcallowip=192.168.*` | `-rpcallowip=192.168.0.0/16` |
|
||||
| `-rpcallowip=*` (dangerous!) | `-rpcallowip=::/0` (still dangerous!) |
|
||||
|
||||
Using wildcards will result in the rule being rejected with the following error in debug.log:
|
||||
|
||||
Error: Invalid -rpcallowip subnet specification: *. Valid are a single IP (e.g. 1.2.3.4), a network/netmask (e.g. 1.2.3.4/255.255.255.0) or a network/CIDR (e.g. 1.2.3.4/24).
|
||||
|
||||
|
||||
REST interface
|
||||
--------------
|
||||
|
||||
A new HTTP API is exposed when running with the `-rest` flag, which allows
|
||||
unauthenticated access to public node data.
|
||||
|
||||
It is served on the same port as RPC, but does not need a password, and uses
|
||||
plain HTTP instead of JSON-RPC.
|
||||
|
||||
Assuming a local RPC server running on port 8332, it is possible to request:
|
||||
- Blocks: http://localhost:8332/rest/block/*HASH*.*EXT*
|
||||
- Blocks without transactions: http://localhost:8332/rest/block/notxdetails/*HASH*.*EXT*
|
||||
- Transactions (requires `-txindex`): http://localhost:8332/rest/tx/*HASH*.*EXT*
|
||||
|
||||
In every case, *EXT* can be `bin` (for raw binary data), `hex` (for hex-encoded
|
||||
binary) or `json`.
|
||||
|
||||
For more details, see the `doc/REST-interface.md` document in the repository.
|
||||
|
||||
RPC Server "Warm-Up" Mode
|
||||
-------------------------
|
||||
|
||||
The RPC server is started earlier now, before most of the expensive
|
||||
intialisations like loading the block index. It is available now almost
|
||||
immediately after starting the process. However, until all initialisations
|
||||
are done, it always returns an immediate error with code -28 to all calls.
|
||||
|
||||
This new behaviour can be useful for clients to know that a server is already
|
||||
started and will be available soon (for instance, so that they do not
|
||||
have to start it themselves).
|
||||
|
||||
Improved signing security
|
||||
-------------------------
|
||||
|
||||
For 0.10 the security of signing against unusual attacks has been
|
||||
improved by making the signatures constant time and deterministic.
|
||||
|
||||
This change is a result of switching signing to use libsecp256k1
|
||||
instead of OpenSSL. Libsecp256k1 is a cryptographic library
|
||||
optimized for the curve Bitcoin uses which was created by Bitcoin
|
||||
Core developer Pieter Wuille.
|
||||
|
||||
There exist attacks[1] against most ECC implementations where an
|
||||
attacker on shared virtual machine hardware could extract a private
|
||||
key if they could cause a target to sign using the same key hundreds
|
||||
of times. While using shared hosts and reusing keys are inadvisable
|
||||
for other reasons, it's a better practice to avoid the exposure.
|
||||
|
||||
OpenSSL has code in their source repository for derandomization
|
||||
and reduction in timing leaks that we've eagerly wanted to use for a
|
||||
long time, but this functionality has still not made its
|
||||
way into a released version of OpenSSL. Libsecp256k1 achieves
|
||||
significantly stronger protection: As far as we're aware this is
|
||||
the only deployed implementation of constant time signing for
|
||||
the curve Bitcoin uses and we have reason to believe that
|
||||
libsecp256k1 is better tested and more thoroughly reviewed
|
||||
than the implementation in OpenSSL.

||||

|
||||
|
||||
Watch-only wallet support
|
||||
-------------------------
|
||||
|
||||
The wallet can now track transactions to and from wallets for which you know
|
||||
all addresses (or scripts), even without the private keys.
|
||||
|
||||
This can be used to track payments without needing the private keys online on a
|
||||
possibly vulnerable system. In addition, it can help for (manual) construction
|
||||
of multisig transactions where you are only one of the signers.
|
||||
|
||||
One new RPC, `importaddress`, is added which functions similarly to
|
||||
`importprivkey`, but instead takes an address or script (in hexadecimal) as
|
||||
argument. After using it, outputs credited to this address or script are
|
||||
considered to be received, and transactions consuming these outputs will be
|
||||
considered to be sent.
|
||||
|
||||
The following RPCs have optional support for watch-only:
|
||||
`getbalance`, `listreceivedbyaddress`, `listreceivedbyaccount`,
|
||||
`listtransactions`, `listaccounts`, `listsinceblock`, `gettransaction`. See the
|
||||
RPC documentation for those methods for more information.
|
||||
|
||||
Compared to using `getrawtransaction`, this mechanism does not require
|
||||
`-txindex`, scales better, integrates better with the wallet, and is compatible
|
||||
with future block chain pruning functionality. It does mean that all relevant
|
||||
addresses need to added to the wallet before the payment, though.
|
||||
|
||||
Consensus library
|
||||
-----------------
|
||||
|
||||
Starting from 0.10.0, the Bitcoin Core distribution includes a consensus library.
|
||||
|
||||
The purpose of this library is to make the verification functionality that is
|
||||
critical to Bitcoin's consensus available to other applications, e.g. to language
|
||||
bindings such as [python-bitcoinlib](https://pypi.python.org/pypi/python-bitcoinlib) or
|
||||
alternative node implementations.
|
||||
|
||||
This library is called `libbitcoinconsensus.so` (or, `.dll` for Windows).
|
||||
Its interface is defined in the C header [bitcoinconsensus.h](https://github.com/bitcoin/bitcoin/blob/0.10/src/script/bitcoinconsensus.h).
|
||||
|
||||
In its initial version the API includes two functions:
|
||||
|
||||
- `bitcoinconsensus_verify_script` verifies a script. It returns whether the indicated input of the provided serialized transaction
|
||||
correctly spends the passed scriptPubKey under additional constraints indicated by flags
|
||||
- `bitcoinconsensus_version` returns the API version, currently at an experimental `0`
|
||||
|
||||
The functionality is planned to be extended to e.g. UTXO management in upcoming releases, but the interface
|
||||
for existing methods should remain stable.
|
||||
|
||||
Standard script rules relaxed for P2SH addresses
|
||||
------------------------------------------------
|
||||
|
||||
The IsStandard() rules have been almost completely removed for P2SH
|
||||
redemption scripts, allowing applications to make use of any valid
|
||||
script type, such as "n-of-m OR y", hash-locked oracle addresses, etc.
|
||||
While the Bitcoin protocol has always supported these types of script,
|
||||
actually using them on mainnet has been previously inconvenient as
|
||||
standard Bitcoin Core nodes wouldn't relay them to miners, nor would
|
||||
most miners include them in blocks they mined.
|
||||
|
||||
bitcoin-tx
|
||||
----------
|
||||
|
||||
It has been observed that many of the RPC functions offered by bitcoind are
|
||||
"pure functions", and operate independently of the bitcoind wallet. This
|
||||
included many of the RPC "raw transaction" API functions, such as
|
||||
createrawtransaction.
|
||||
|
||||
bitcoin-tx is a newly introduced command line utility designed to enable easy
|
||||
manipulation of bitcoin transactions. A summary of its operation may be
|
||||
obtained via "bitcoin-tx --help" Transactions may be created or signed in a
|
||||
manner similar to the RPC raw tx API. Transactions may be updated, deleting
|
||||
inputs or outputs, or appending new inputs and outputs. Custom scripts may be
|
||||
easily composed using a simple text notation, borrowed from the bitcoin test
|
||||
suite.
|
||||
|
||||
This tool may be used for experimenting with new transaction types, signing
|
||||
multi-party transactions, and many other uses. Long term, the goal is to
|
||||
deprecate and remove "pure function" RPC API calls, as those do not require a
|
||||
server round-trip to execute.
|
||||
|
||||
Other utilities "bitcoin-key" and "bitcoin-script" have been proposed, making
|
||||
key and script operations easily accessible via command line.
|
||||
|
||||
Mining and relay policy enhancements
|
||||
------------------------------------
|
||||
|
||||
Bitcoin Core's block templates are now for version 3 blocks only, and any mining
|
||||
software relying on its `getblocktemplate` must be updated in parallel to use
|
||||
libblkmaker either version 0.4.2 or any version from 0.5.1 onward.
|
||||
If you are solo mining, this will affect you the moment you upgrade Bitcoin
|
||||
Core, which must be done prior to BIP66 achieving its 951/1001 status.
|
||||
If you are mining with the stratum mining protocol: this does not affect you.
|
||||
If you are mining with the getblocktemplate protocol to a pool: this will affect
|
||||
you at the pool operator's discretion, which must be no later than BIP66
|
||||
achieving its 951/1001 status.
|
||||
|
||||
The `prioritisetransaction` RPC method has been added to enable miners to
|
||||
manipulate the priority of transactions on an individual basis.
|
||||
|
||||
Bitcoin Core now supports BIP 22 long polling, so mining software can be
|
||||
notified immediately of new templates rather than having to poll periodically.
|
||||
|
||||
Support for BIP 23 block proposals is now available in Bitcoin Core's
|
||||
`getblocktemplate` method. This enables miners to check the basic validity of
|
||||
their next block before expending work on it, reducing risks of accidental
|
||||
hardforks or mining invalid blocks.
|
||||
|
||||
Two new options to control mining policy:
|
||||
- `-datacarrier=0/1` : Relay and mine "data carrier" (OP_RETURN) transactions
|
||||
if this is 1.
|
||||
- `-datacarriersize=n` : Maximum size, in bytes, we consider acceptable for
|
||||
"data carrier" outputs.
|
||||
|
||||
The relay policy has changed to more properly implement the desired behavior of not
|
||||
relaying free (or very low fee) transactions unless they have a priority above the
|
||||
AllowFreeThreshold(), in which case they are relayed subject to the rate limiter.
|
||||
|
||||
BIP 66: strict DER encoding for signatures
|
||||
------------------------------------------
|
||||
|
||||
Bitcoin Core 0.10 implements BIP 66, which introduces block version 3, and a new
|
||||
consensus rule, which prohibits non-DER signatures. Such transactions have been
|
||||
non-standard since Bitcoin v0.8.0 (released in February 2013), but were
|
||||
technically still permitted inside blocks.
|
||||
|
||||
This change breaks the dependency on OpenSSL's signature parsing, and is
|
||||
required if implementations would want to remove all of OpenSSL from the
|
||||
consensus code.
|
||||
|
||||
The same miner-voting mechanism as in BIP 34 is used: when 751 out of a
|
||||
sequence of 1001 blocks have version number 3 or higher, the new consensus
|
||||
rule becomes active for those blocks. When 951 out of a sequence of 1001
|
||||
blocks have version number 3 or higher, it becomes mandatory for all blocks.
|
||||
|
||||
Backward compatibility with current mining software is NOT provided, thus miners
|
||||
should read the first paragraph of "Mining and relay policy enhancements" above.
|
||||

||||

Bitcoin Core version 0.9.4 is now available from:
|
||||
|
||||
https://bitcoin.org/bin/0.9.4/
|
||||
|
||||
This is a new minor version release, bringing only bug fixes and updated
|
||||
translations. Upgrading to this release is recommended.
|
||||
|
||||
Please report bugs using the issue tracker at github:
|
||||
|
||||
https://github.com/bitcoin/bitcoin/issues
|
||||
|
||||
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).
|
||||
|
||||
OpenSSL Warning
|
||||
================
|
||||
|
||||
OpenSSL 1.0.0p / 1.0.1k was recently released and is being pushed out by
|
||||
various operating system maintainers. Review by Gregory Maxwell determined that
|
||||
this update is incompatible with the Bitcoin system and could lead to consensus
|
||||
forks.
|
||||
|
||||
Bitcoin Core released binaries from https://bitcoin.org are unaffected,
|
||||
as are any built with the gitian deterministic build system.
|
||||
|
||||
However, if you are running either
|
||||
|
||||
- The Ubuntu PPA from https://launchpad.net/~bitcoin/+archive/ubuntu/bitcoin
|
||||
- A third-party or self-compiled Bitcoin Core
|
||||
|
||||
upgrade to Bitcoin Core 0.9.4, which includes a workaround, **before** updating
|
||||
OpenSSL.
|
||||
|
||||
The incompatibility is due to the OpenSSL update changing the
|
||||
behavior of ECDSA validation to reject any signature which is
|
||||
not encoded in a very rigid manner. This was a result of
|
||||
OpenSSL's change for CVE-2014-8275 "Certificate fingerprints
|
||||
can be modified".
|
||||
|
||||
We are specifically aware of potential hard-forks due to signature
|
||||
encoding handling and had been hoping to close them via BIP62 in 0.10.
|
||||
BIP62's purpose is to improve transaction malleability handling and
|
||||
as a side effect rigidly defines the encoding for signatures, but the
|
||||
overall scope of BIP62 has made it take longer than we'd like to
|
||||
deploy.
|
||||
|
||||
