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 in some cases), then run the
installer (on Windows) or just copy over `/Applications/Bitcoin-Qt` (on Mac)
or `bitcoind`/`bitcoin-qt` (on Linux).

Upgrading directly from a version of Bitcoin Core that has reached its EOL is
possible, but it might take some time if the data directory needs to be 
migrated. Old
wallet versions of Bitcoin Core are generally supported.

Compatibility
==

Bitcoin Core is supported and extensively tested on operating systems
using the Linux kernel, macOS 10.12+, and Windows 7 and newer.  Bitcoin
Core should also work on most other Unix-like systems but is not as
frequently tested on them.  It is not recommended to use Bitcoin Core on
unsupported systems.

- From Bitcoin Core 0.20.0 onwards, macOS versions earlier than 10.12 are no
longer supported. Additionally, Bitcoin Core does not yet change appearance
when macOS "dark mode" is activated.

The node's known peers are persisted to disk in a file called `peers.dat`. The
format of this file has been changed in a backwards-incompatible way in order to
accommodate the storage of Tor v3 and other BIP155 addresses. This means that if
the file is modified by 0.21.0 or newer then older versions will not be able to
read it. Those old versions, in the event of a downgrade, will log an error
message "Incorrect keysize in addrman deserialization" and will continue normal
operation as if the file was missing, creating a new empty one. (#19954, #20284)

Notable changes
===

P2P and network changes
- ---

- - The mempool now tracks whether transactions submitted via the wallet or RPCs
  have been successfully broadcast. Every 10-15 minutes, the node will try to
  announce unbroadcast transactions until a peer requests it via a `getdata`
  message or the transaction is removed from the mempool for other reasons.
  The node will not track the broadcast status of transactions submitted to the
  node using P2P relay. This version reduces the initial broadcast guarantees
  for wallet transactions submitted via P2P to a node running the wallet. 
(#18038)

- - The size of the set of transactions that peers have announced and we 
consider
  for requests has been reduced from 10 to 5000 (per peer), and further
  announcements will be ignored when that limit is reached. If you need to dump
  (very) large batches of transactions, exceptions can be made for trusted
  peers using the "relay" network permission. For localhost for example it can
  be enabled using the command line option `-whitelist=relay@127.0.0.1`.
  (#19988)

- - This release adds support for Tor version 3 hidden services, and rumoring 
them
  over the network to other peers using
  [BIP155](https://github.com/bitcoin/bips/blob/master/bip-0155.mediawiki).
  Version 2 hidden services are still fully supported by Bitcoin Core, but the
  Tor network will start
  [deprecating](https://blog.torproject.org/v2-deprecation-timeline) them in the
  coming months. (#19954)

- - The Tor onion service that is automatically created by setting the
  `-listenonion` configuration parameter will now be created as a Tor v3 service
  instead of Tor v2. The private key that was used for Tor v2 (if any) will be
  left untouched in the `onion_private_key` file in the data directory (see
  `-datadir`) and can be removed if not needed. Bitcoin Core will no longer
  attempt to read it. The private key for the Tor v3 service will be saved in a
  file named `onion_v3_private_key`. To use the deprecated Tor v2 service (not
  recommended), the `onion_private_key` can be copied over
  `onion_v3_private_key`, e.g.
  `cp -f onion_private_key onion_v3_private_key`. (#19954)

- - The client writes a file (`anchors.dat`) at shutdown with the network 
addresses
  of the node’s two outbound block-relay-only peers (so called "anchors").

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 in some cases), then run the
installer (on Windows) or just copy over `/Applications/Bitcoin-Qt` (on Mac)
or `bitcoind`/`bitcoin-qt` (on Linux).

Upgrading directly from a version of Bitcoin Core that has reached its EOL is
possible, but it might take some time if the data directory needs to be 
migrated. Old
wallet versions of Bitcoin Core are generally supported.

Compatibility
==

Bitcoin Core is supported and extensively tested on operating systems
using the Linux kernel, macOS 10.12+, and Windows 7 and newer.  Bitcoin
Core should also work on most other Unix-like systems but is not as
frequently tested on them.  It is not recommended to use Bitcoin Core on
unsupported systems.

- From Bitcoin Core 0.20.0 onwards, macOS versions earlier than 10.12 are no
longer supported. Additionally, Bitcoin Core does not yet change appearance
when macOS "dark mode" is activated.

Known Bugs
==

The process for generating the source code release ("tarball") has changed in an
effort to make it more complete, however, there are a few regressions in
this release:

- - The generated `configure` script is currently missing, and you will need to
  install autotools and run `./autogen.sh` before you can run
  `./configure`. This is the same as when checking out from git.

- - Instead of running `make` simply, you should instead run
  `BITCOIN_GENBUILD_NO_GIT=1 make`.

Notable changes
===

P2P and network changes
- ---

 Removal of BIP61 reject network messages from Bitcoin Core

The `-enablebip61` command line option to enable BIP61 has been removed.
(#17004)

This feature has been disabled by default since Bitcoin Core version 0.18.0.
Nodes on the network can not generally be trusted to send valid messages
(including reject messages), so this should only ever be used when
connected to a trusted node.  Please use the alternatives recommended
below if you rely on this removed feature:

- - Testing or debugging of implementations of the Bitcoin P2P network protocol
  should be done by inspecting the log messages that are produced by a recent
  version of Bitcoin Core. Bitcoin Core logs debug messages
  (`-debug=`) to a stream (`-printtoconsole`) or to a file
  (`-debuglogfile=`).

- - Testing the validity of a block can be achieved by specific RPCs:

  - `submitblock`

  - `getblocktemplate` with `'mode'` set to `'proposal'` for blocks with
potentially invalid POW

- - Testing the validity of a transaction can be achieved by specific RPCs:

  - `sendrawtransaction`

  - `testmempoolaccept`

- - Wallets should not assume a transaction has propagated to the network
  just because there are no reject messages.  Instead, listen for the
  transaction to be announced by other peers on the network.  Wallets
  should not assume a lack of reject messages means a transaction pays
  an appropriate fee.  Instead, set fees using fee estimation and use
  replace-by-fee to increase a transaction's fee if it hasn't confirmed
  within the desired amount of time.

The removal of BIP61 reject message support also has the following minor RPC
and logging implications:

- - `testmempoolaccept` and `sendrawtransaction` no longer return the P2P reject
  code when a transaction is not accepted to the mempool. They still return the
  verbal reject reason.

- - Log messages that previously reported the reject code when a transaction was
  not accepted to the mempool now no longer report the reject code. The reason
  for rejection is still reported.

Updated RPCs
- 

- - The RPCs which accept descriptors now accept the new `sortedmulti(...)` 
descriptor
  type which supports multisig scripts where the public keys are sorted
  lexicographically in the resulting script.  (#17056)

- - The `walletprocesspsbt`

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).

Upgrading directly from a version of Bitcoin Core that has reached its EOL is
possible, but it might take some time if the datadir needs to be migrated. Old
wallet versions of Bitcoin Core are generally supported.

Compatibility
==

Bitcoin Core is supported and extensively tested on operating systems using
the Linux kernel, macOS 10.10+, and Windows 7 and newer. It is not recommended
to use Bitcoin Core on unsupported systems.

Bitcoin Core should also work on most other Unix-like systems but is not
as frequently tested on them.

- From Bitcoin Core 0.17.0 onwards, macOS versions earlier than 10.10 are no
longer supported, as Bitcoin Core is now built using Qt 5.9.x which requires
macOS 10.10+. Additionally, Bitcoin Core does not yet change appearance when
macOS "dark mode" is activated.

In addition to previously supported CPU platforms, this release's pre-compiled
distribution provides binaries for the RISC-V platform.

This release includes new features, various bug fixes and performance
improvements, as well as updated translations.

Please report bugs using the issue tracker at GitHub:

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).

Upgrading directly from a version of Bitcoin Core that has reached its EOL is
possible, but might take some time if the datadir needs to be migrated.  Old
wallet versions of Bitcoin Core are generally supported.

Compatibility
==

Bitcoin Core is supported and extensively tested on operating systems using
the Linux kernel, macOS 10.10+, and Windows 7 and newer. It is not recommended
to use Bitcoin Core on unsupported systems.

Bitcoin Core should also work on most other Unix-like systems but is not
as frequently tested on them.

- From 0.17.0 onwards, macOS <10.10 is no longer supported. 0.17.0 is
built using Qt 5.9.x, which doesn't support versions of macOS older than
10.10. Additionally, Bitcoin Core does not yet change appearance when
macOS "dark mode" is activated.

Users running macOS Catalina may need to "right-click" and then choose "Open"
to open the Bitcoin Core .dmg. This is due to new signing requirements
imposed by Apple, which the Bitcoin Core project does not yet adhere too.

Notable changes
===

New user documentation
- --

- - [Reduce 
memory](https://github.com/bitcoin/bitcoin/blob/master/doc/reduce-memory.md)
  suggests configuration tweaks for running Bitcoin Core on systems with
  limited memory. (#16339)

New RPCs
- 

- - `getbalances` returns an object with all balances (`mine`,
  `untrusted_pending` and `immature`). Please refer to the RPC help of
  `getbalances` for details. The new RPC is intended to replace
  `getbalance`, `getunconfirmedbalance`, and the balance fields in
  `getwalletinfo`.  These old calls and fields may be removed in a
  future version. (#15930, #16239)

- - `setwalletflag` sets and unsets wallet flags that enable or disable
  features specific to that existing wallet, such as the new
  `avoid_reuse` feature documented elsewhere in these release notes.
  (#13756)

- - `getblockfilter` gets the BIP158 filter for the specified block.  This
  RPC is only enabled if block filters have been created using the
  `-blockfilterindex` configuration option. (#14121)

New settings
- 

- - `-blockfilterindex` enables the creation of BIP158 block filters for
  the entire blockchain.  Filters will be created in the background and
  currently use about 4 GiB of space.  Note: this version of Bitcoin
  Core does not serve block filters over the P2P network, although the
  local user may obtain block filters using the `getblockfilter` RPC.
  (#14121)

Updated settings
- 

- - `whitebind` and `whitelist` now accept a list of permissions to
  provide peers connecting using the indicated interfaces or IP
  addresses.  If no permissions are specified with an address or CIDR
  network, the implicit default permissions are the same as previous
  releases.  See the `bitcoind -help` output for these two options for
  details about the available permissions. (#16248)

- - Users setting custom `dbcache` values can increase their setting slightly
  without using any more real memory.  Recent changes reduced the memory use
  by about 9% and made chainstate accounting more accurate (it was 
underestimating
  the use of memory before).  For example, if you set a value of "450" before, 
you
  may now set a value of "500" to use about the same real amount of memory. 
(#16957)


Updated RPCs
- 

Note: some low-level RPC changes mainly useful for testing are described in the
Low-level Changes section below.

- - `sendmany` no longer has a `minconf` argument.  This argument was not
  well-specified and would lead to RPC errors even when the wallet's
  coin selection succeeded.  Users who want to influence coin selection
  can use the existing

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).

The first time you run version 0.15.0 or newer, your chainstate database
will be converted to a new format, which will take anywhere from a few
minutes to half an hour, depending on the speed of your machine.

Note that the block database format also changed in version 0.8.0 and
there is no automatic upgrade code from before version 0.8 to version
0.15.0 or later. Upgrading directly from 0.7.x and earlier without
redownloading the blockchain is not supported.  However, as usual, old
wallet versions are still supported.

Compatibility
==

Bitcoin Core is supported and extensively tested on operating systems
using the Linux kernel, macOS 10.10+, and Windows 7 and newer. It is not
recommended to use Bitcoin Core on unsupported systems.

Bitcoin Core should also work on most other Unix-like systems but is not
as frequently tested on them.

- From 0.17.0 onwards, macOS <10.10 is no longer supported. 0.17.0 is
built using Qt 5.9.x, which doesn't support versions of macOS older than
10.10. Additionally, Bitcoin Core does not yet change appearance when
macOS "dark mode" is activated.

In addition to previously-supported CPU platforms, this release's
pre-compiled distribution also provides binaries for the RISC-V
platform.

If you are using the `systemd` unit configuration file located at
`contrib/init/bitcoind.service`, it has been changed to use
`/var/lib/bitcoind` as the data directory instead of
`~bitcoin/.bitcoin`. When switching over to the new configuration file,
please make sure that the filesystem on which `/var/lib/bitcoind` will
exist has enough space (check using `df -h /var/lib/bitcoind`), and
optionally copy over your existing data directory. See the [systemd init
file section](#systemd-init-file) for more details.

Known issues


Wallet GUI
- --

For advanced users who have both (1) enabled coin control features, and
(2) are using multiple wallets loaded at the same time: The coin control
input selection dialog can erroneously retain wrong-wallet state when
switching wallets using the dropdown menu. For now, it is recommended
not to use coin control features with multiple wallets loaded.

Notable changes
===

Mining
- --

- - Calls to `getblocktemplate` will fail if the segwit rule is not
  specified.  Calling `getblocktemplate` without segwit specified is
  almost certainly a misconfiguration since doing so results in lower
  rewards for the miner.  Failed calls will produce an error message
  describing how to enable the segwit rule.

Configuration option changes
- 

- - A warning is printed if an unrecognized section name is used in the
  configuration file.  Recognized sections are `[test]`, `[main]`, and
  `[regtest]`.

- - Four new options are available for configuring the maximum number of
  messages that ZMQ will queue in memory (the "high water mark") before
  dropping additional messages.  The default value is 1,000, the same as
  was used for previous releases.  See the [ZMQ
  
documentation](https://github.com/bitcoin/bitcoin/blob/master/doc/zmq.md#usage)
  for details.

- - The `rpcallowip` option can no longer be used to automatically listen
  on all network interfaces.  Instead, the `rpcbind` parameter must be
  used to specify the IP addresses to listen on.  Listening for RPC
  commands over a public network connection is insecure and should be
  disabled, so a warning is now printed if a user selects such a
  configuration.  If you need to expose RPC in order to use a tool like
  Docker, ensure you only bind RPC to your localhost, e.g. `docker run
  [...] -p 127.0.0.1:8332:8332` (this is an extra `:8332` over the
  normal Docker port specification).

- - The `rpcpassword` option now causes a startup error if the password
  set in the configuration

[bitcoin-dev] BIP proposal - addrv2 message

2019-03-05 Thread Wladimir J. van der Laan via bitcoin-dev 
See https://gist.github.com/laanwj/4fe8470881d7b9499eedc48dc9ef1ad1 for 
formatted version,

Look under "Considerations" for topics that might still need to be discussed.


  BIP: ???
  Layer: Peer Services
  Title: addrv2 message
  Author: Wladimir J. van der Laan 
  Comments-Summary: No comments yet.
  Comments-URI: 
  Status: Draft
  Type: Standards Track
  Created: 2018-06-01
  License: BSD-2-Clause


==Introduction==

===Abstract===

This document proposes a new P2P message to gossip longer node addresses over 
the P2P network.
This is required to support new-generation Onion addresses, I2P, and 
potentially other networks
that have longer endpoint addresses than fit in the 128 bits of the current 
addr message.

===Copyright===

This BIP is licensed under the 2-clause BSD license.

===Motivation===

Tor v3 hidden services are part of the stable release of Tor since version 
0.3.2.9. They have
various advantages compared to the old hidden services, among which better 
encryption and privacy
[https://gitweb.torproject.org/torspec.git/tree/rend-spec-v3.txt Tor 
Rendezvous Specification - Version 3].
These services have 256 bit addresses and thus do not fit in the existing 
addr message, which encapsulates onion addresses in OnionCat IPv6 
addresses.

Other transport-layer protocols such as I2P have always used longer
addresses. This change would make it possible to gossip such addresses over the
P2P network, so that other peers can connect to them.

==Specification==


The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD",
"SHOULD NOT", "RECOMMENDED",  "MAY", and "OPTIONAL" in this document are to be
interpreted as described in RFC 2119[https://tools.ietf.org/html/rfc2119 
RFC 2119].


The addrv2 message is defined as a message where pchCommand 
== "addrv2".
It is serialized in the standard encoding for P2P messages.
Its format is similar to the current addr message format
[https://bitcoin.org/en/developer-reference#addr Bitcoin Developer 
Reference: addr message], with the difference that the 
fixed 16-byte IP address is replaced by a network ID and a variable-length 
address, and the time and services format has been changed to VARINT.

This means that the message contains a serialized std::vector of 
the following structure:

{| class="wikitable" style="width: auto; text-align: center; font-size: 
smaller; table-layout: fixed;"
!Type
!Name
!Description
|-
| VARINT (unsigned)
| time
| Time that this node was last seen as connected to the network. A time in Unix 
epoch time format, up to 64 bits wide.
|-
| VARINT (unsigned)
| services
| Service bits. A 64-wide bit field.
|-
| uint8_t
| networkID
| Network identifier. An 8-bit value that specifies which network is addressed.
|-
| std::vector
| addr
| Network address. The interpretation depends on networkID.
|-
| uint16_t
| port
| Network port. If not relevant for the network this MUST be 0.
|}

One message can contain up to 1,000 addresses. Clients SHOULD reject messages 
with more addresses.

Field addr has a variable length, with a maximum of 32 bytes (256 
bits). Clients SHOULD reject
longer addresses.

The list of reserved network IDs is as follows:

{| class="wikitable" style="width: auto; text-align: center; font-size: 
smaller; table-layout: fixed;"
!Network ID
!Enumeration
!Address length (bytes)
!Description
|-
| 0x01
| IPV4
| 4
| IPv4 address (globally routed internet)
|-
| 0x02
| IPV6
| 16
| IPv6 address (globally routed internet)
|-
| 0x03
| TORV2
| 10
| Tor v2 hidden service address
|-
| 0x04
| TORV3
| 32
| Tor v3 hidden service address
|-
| 0x05
| I2P
| 32
| I2P overlay network address
|-
| 0x06
| CJDNS
| 16
| Cjdns overlay network address
|}

To allow for future extensibility, clients MUST ignore address types that they 
do not know about.
Client MAY store and gossip address formats that they do not know about. 
Further network ID numbers MUST be reserved in a new BIP document.

Clients SHOULD reject addresses that have a different length than specified in 
this table for a specific address ID, as these are meaningless.

See the appendices for the address encodings to be used for the various 
networks.

==Compatibility==

Send addrv2 messages only, and exclusively, when the peer has a 
certain protocol version (or higher):

//! gossiping using `addrv2` messages starts with this version
static const int GOSSIP_ADDRV2_VERSION = 70016;

For older peers keep sending the legacy addr message, ignoring 
addresses with the newly introduced address types.

==Reference implementation==

The reference implementation is available at (to be done)

==Considerations==

(to be discussed)

* ''Client MAY store and gossip address formats that they do not know about'': 
does it ever make sense to gossip addresses outside a certain overlay network? 
Say, I2P addresses to Tor?

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).

If your node has a txindex, the txindex db will be migrated the first time you 
run 0.17.0 or newer, which may take up to a few hours. Your node will not be 
functional until this migration completes.

The first time you run version 0.15.0 or newer, your chainstate database will 
be converted to a
new format, which will take anywhere from a few minutes to half an hour,
depending on the speed of your machine.

Note that the block database format also changed in version 0.8.0 and there is 
no
automatic upgrade code from before version 0.8 to version 0.15.0. Upgrading
directly from 0.7.x and earlier without redownloading the blockchain is not 
supported.
However, as usual, old wallet versions are still supported.

Downgrading warning
- ---

The chainstate database for this release is not compatible with previous
releases, so if you run 0.15 and then decide to switch back to any
older version, you will need to run the old release with the 
`-reindex-chainstate`
option to rebuild the chainstate data structures in the old format.

If your node has pruning enabled, this will entail re-downloading and
processing the entire blockchain.

Compatibility
==

Bitcoin Core is extensively tested on multiple operating systems using
the Linux kernel, macOS 10.10+, and Windows 7 and newer (Windows XP is not 
supported).

Bitcoin Core should also work on most other Unix-like systems but is not
frequently tested on them.

- From 0.17.0 onwards macOS <10.10 is no longer supported. 0.17.0 is built 
using Qt 5.9.x, which doesn't
support versions of macOS older than 10.10.

Known issues


- - Upgrading from 0.13.0 or older currently results in memory blow-up during 
the roll-back of blocks to the SegWit activation point. In these cases, a full 
`-reindex` is necessary.

- - The GUI suffers from visual glitches in the new MacOS dark mode. This has 
to do with our Qt theme handling and is not a new problem in 0.17.0, but is 
expected to be resolved in 0.17.1.

Notable changes
===

Changed configuration options
- -

- - `-includeconf=` can be used to include additional configuration files.
  Only works inside the `bitcoin.conf` file, not inside included files or from
  command-line. Multiple files may be included. Can be disabled from command-
  line via `-noincludeconf`. Note that multi-argument commands like
  `-includeconf` will override preceding `-noincludeconf`, i.e.
  ```
  noincludeconf=1
  includeconf=relative.conf
  ```

  as bitcoin.conf will still include `relative.conf`.

GUI changes
- ---

- - Block storage can be limited under Preferences, in the Main tab. Undoing 
this setting requires downloading the full blockchain again. This mode is 
incompatible with -txindex and -rescan.

External wallet files
- -

The `-wallet=` option now accepts full paths instead of requiring wallets
to be located in the -walletdir directory.

Newly created wallet format
- ---

If `-wallet=` is specified with a path that does not exist, it will now
create a wallet directory at the specified location (containing a wallet.dat
data file, a db.log file, and database/log.?? files) instead of just
creating a data file at the path and storing log files in the parent
directory. This should make backing up wallets more straightforward than
before because the specified wallet path can just be directly archived without
having to look in the parent directory for transaction log files.

For backwards compatibility, wallet paths that are names of existing data files
in the `-walletdir` directory will continue to be accepted and interpreted the
same as before.

Dynamic loading and creation of wallets
- ---

Denial-of-Service vulnerability CVE-2018-17144
 ---

A denial-of-service vulnerability exploitable by miners has been discovered in
Bitcoin Core versions 0.14.0 up to 0.16.2. It is recommended to upgrade any of
the vulnerable versions to 0.14.3, 0.15.2 or 0.16.3 as soon as possible.

Known Bugs
==

Since 0.14.0 the approximate transaction fee shown in Bitcoin-Qt when using coin
control and smart fee estimation does not reflect any change in target from the
smart fee slider. It will only present an approximate fee calculated using the
default target. The fee calculated using the correct target is still applied to
the transaction and shown in the final send confirmation dialog.

new format, which will take anywhere from a few minutes to half an hour,
depending on the speed of your machine.

Note that the block database format also changed in version 0.8.0 and there is 
no
automatic upgrade code from before version 0.8 to version 0.15.0 or higher. 
Upgrading
directly from 0.7.x and earlier without re-downloading the blockchain is not 
supported.
However, as usual, old wallet versions are still supported.

Downgrading warning
- ---

Wallets created in 0.16 and later are not compatible with versions prior to 0.16
and will not work if you try to use newly created wallets in older versions. 
Existing
wallets that were created with older versions are not affected by this.

Compatibility
==

Bitcoin Core is extensively tested on multiple operating systems using
the Linux kernel, macOS 10.8+, and Windows Vista and later. Windows XP is not 
supported.

Bitcoin Core should also work on most other Unix-like systems but is not
frequently tested on them.

Notable changes
===

Denial-of-Service vulnerability
- ---

A denial-of-service vulnerability (CVE-2018-17144) exploitable by miners has
been discovered in Bitcoin Core versions 0.14.0 up to 0.16.2. It is recommended
to upgrade any of the vulnerable versions to 0.16.3 as soon as possible.

0.16.3 change log

[bitcoin-dev] Bitcoin Core 0.15.0 released

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).

The first time you run version 0.15.0, your chainstate database will be 
converted to a
new format, which will take anywhere from a few minutes to half an hour,
depending on the speed of your machine.

The file format of `fee_estimates.dat` changed in version 0.15.0. Hence, a
downgrade from version 0.15.0 or upgrade to version 0.15.0 will cause all fee
estimates to be discarded.

Note that the block database format also changed in version 0.8.0 and there is 
no
automatic upgrade code from before version 0.8 to version 0.15.0. Upgrading
directly from 0.7.x and earlier without redownloading the blockchain is not 
supported.
However, as usual, old wallet versions are still supported.

Downgrading warning
- ---

The chainstate database for this release is not compatible with previous
releases, so if you run 0.15 and then decide to switch back to any
older version, you will need to run the old release with the 
`-reindex-chainstate`
option to rebuild the chainstate data structures in the old format.

If your node has pruning enabled, this will entail re-downloading and
processing the entire blockchain.

Compatibility
==

Bitcoin Core is extensively tested on multiple operating systems using
the Linux kernel, macOS 10.8+, and Windows Vista and later. Windows XP is not 
supported.

Bitcoin Core should also work on most other Unix-like systems but is not
frequently tested on them.

Notes for 0.15.0


Current SegWit support
- --

Version 0.15.0 supports adding a segregated witness address via the 
`addwitnessaddress` RPC, but
please note that this is a testing/expert RPC, which does not guarantee 
recovery from backup. Only use
this RPC if you know what you are doing. More complete wallet support for 
segregated witness is coming
in a next version.

Rescanning with encrypted wallets
- -

As in previous versions, when using an encrypted HD wallet, the keypool cannot 
be topped up without unlocking
the wallet. This means that currently, in order to recover from a backup of an 
encrypted HD wallet, the user
must unlock the wallet with a really long timeout and manually trigger a 
rescan, otherwise they risk missing
some keys when auto-topup cannot run. Unfortunately there is no `rescan` RPC in 
this version, that will be
included in a future version, so for now a rescan can be triggered using one of 
the `import*` commands, using
a dummy address generated by another (trusted) wallet.

Notable changes
===

Performance Improvements
- 

Version 0.15 contains a number of significant performance improvements, which 
make
Initial Block Download, startup, transaction and block validation much faster:

- - The chainstate database (which is used for tracking UTXOs) has been changed
  from a per-transaction model to a per-output model (See [PR 
10195](https://github.com/bitcoin/bitcoin/pull/10195)). Advantages of this model
  are that it:
- avoids the CPU overhead of deserializing and serializing the unused 
outputs;
- has more predictable memory usage;
- uses simpler code;
- is adaptable to various future cache flushing strategies.

  As a result, validating the blockchain during Initial Block Download (IBD) 
and reindex
  is ~30-40% faster, uses 10-20% less memory, and flushes to disk far less 
frequently.
  The only downside is that the on-disk database is 15% larger. During the 
conversion from the previous format
  a few extra gigabytes may be used.
- - Earlier versions experienced a spike in memory usage while flushing UTXO 
updates to disk.
  As a result, only half of the available memory was actually used as cache, 
and the other half was

Notable changes
===

miniupnp CVE-2017-8798
- 

Bundled miniupnpc was updated to 2.0.20170509. This fixes an integer signedness 
error
(present in MiniUPnPc v1.4.20101221 through v2.0) that allows remote attackers
(within the LAN) to cause a denial of service or possibly have unspecified
other impact.

This only affects users that have explicitly enabled UPnP through the GUI
setting or through the `-upnp` option, as since the last UPnP vulnerability
(in Bitcoin Core 0.10.3) it has been disabled by default.

If you use this option, it is recommended to upgrade to this version as soon as
possible.

Known Bugs
==

Since 0.14.0 the approximate transaction fee shown in Bitcoin-Qt when using coin
control and smart fee estimation does not reflect any change in target from the
smart fee slider. It will only present an approximate fee calculated using the
default target. The fee calculated using the correct target is still applied to
the transaction and shown in the final send confirmation dialog.

Re: [bitcoin-dev] Completing the retirement of the alert system

As it has been disabled in relevant software I think it's mostly symbolic at
this point, but yes, it makes sense to 'officially' retire the key. Let's
pin the date and make it widely known.

Doing this in organized fashion is much better than the whodunit that would
undoubtly follow when the key would simply leak, which could happen at any
time, as no one can know who it has spread to over all those years.

Re: timing, I'd say leave three months grace time after this announcement for
altcoins and such that may have accidentally have copied it to remove it, then
at the beginning of 2017 broadcast the final alert.

After that it's neutered, it's up to each of us that has the key to reveal it
or not or when. It's a historical curiosity then.

[bitcoin-dev] Bitcoin Core 0.12.1 released

2016-04-15 Thread Wladimir J. van der Laan via bitcoin-dev 
at valid blocks have a computed GetMedianTimePast()
greater than the locktime specified in any transaction in that block.

Mempool inclusion rules currently require transactions to be valid for
immediate inclusion in a block in order to be accepted into the mempool.
This release begins applying the BIP113 rule to received transactions,
so transaction whose time is greater than the GetMedianTimePast() will
no longer be accepted into the mempool.

**Implication for miners:** you will begin rejecting transactions that
would not be valid under BIP113, which will prevent you from producing
invalid blocks when BIP113 is enforced on the network. Any
transactions which are valid under the current rules but not yet valid
under the BIP113 rules will either be mined by other miners or delayed
until they are valid under BIP113. Note, however, that time-based
locktime transactions are more or less unseen on the network currently.

**Implication for users:** GetMedianTimePast() always trails behind the
current time, so a transaction locktime set to the present time will be
rejected by nodes running this release until the median time moves
forward. To compensate, subtract one hour (3,600 seconds) from your
locktimes to allow those transactions to be included in mempools at
approximately the expected time.

For more information about the implementation, see

[bitcoin-dev] IRC meetings moved to #bitcoin-core-dev

2016-03-01 Thread Wladimir J. van der Laan via bitcoin-dev 

It seems that MeetingBot was deactivated in #bitcoin-dev, so the
last two weeks the weekly developer meeting (Thursday 19:00-20:00 UTC)
was held in #bitcoin-core-dev.

Let's keep it at that.

Exactly - the plan is that OpenSSL will, in due time, be a dependency only if 
the
GUI is enabled. Most of the work for that is already done but it has to be made
up to date and carefully tested and integrated.

It has been tested in git for almost half a year. This RC is the first binary
release that contains the functionality.

It is extremely unlikely that the wallet will eat your coins (always backup
nevertheless), but I can't guarantee there won't be some issue where the wallet
and chain get out of sync and you're forced to redownload the blockchain.

How to enable it is still the same as mentioned in the 0.11 release notes:

[bitcoin-dev] Weekly developer meetings over holidays

2015-12-22 Thread Wladimir J. van der Laan via bitcoin-dev 

Next two weekly developer meetings would fall on:

- Thursday December 24th
- Thursday December 31th

In my timezone they're xmas eve and new year's eve respectively, so at least I
won't be there, and I'm sure they're inconvenient for most people.

So: let's have a two week hiatus, and continue January 7th.

Thanks for writing this up. Putting the progress, ongoing work and plans related
to scaling in context, in one place, was badly needed.

Sounds good to me.

There are multiple ways to get involved in ongoing work, where the community
can help to make this happen sooner:

- Review the versionbits BIP 
https://github.com/bitcoin/bips/blob/master/bip-0009.mediawiki:

  - Compare and test with implementation: 
https://github.com/bitcoin/bitcoin/pull/6816

- Review CSV BIPs (BIP68 
https://github.com/bitcoin/bips/blob/master/bip-0068.mediawiki / 
   BIP112 https://github.com/bitcoin/bips/blob/master/bip-0112.mediawiki),

  - Compare and test implementation: 

https://github.com/bitcoin/bitcoin/pull/6564  BIP-112: Mempool-only 
CHECKSEQUENCEVERIFY
https://github.com/bitcoin/bitcoin/pull/6312  BIP-68: Mempool-only sequence 
number constraint verification 
https://github.com/bitcoin/bitcoin/pull/7184  [WIP] Implement SequenceLocks 
functions for BIP 68

- Segwit BIP is being written, but has not yet been published.

  - Gregory linked to an implementation but as he mentions it is not completely
finished yet. ETA for a Segwit testnet is later this month, then you can 
test as well.

Re: [bitcoin-dev] Bitcoin Core 0.11.2 released

2015-11-15 Thread Wladimir J. van der Laan via bitcoin-dev 

I'm not sure that's the right way to go about verifing gpg keys.
Copy/pasting from webpages is going to run into padding/character set 
conversion issues, resulting in potential false negatives. If you want to 
verify mails, you have to verify the original mail, which archives don't make 
easy (or even possible).

So I'd do this:

The binary release signing key is signed by my normal key:

$ gpg --list-sigs 36C2E964

pub   4096R/36C2E964 2015-06-24 [expires: 2017-02-13]
uid  Wladimir J. van der Laan (Bitcoin Core binary release 
signing key) <laa...@gmail.com>
sig 336C2E964 2015-06-24  Wladimir J. van der Laan (Bitcoin Core 
binary release signing key) <laa...@gmail.com>
sig  2346C9A6 2015-06-24  Wladimir J. van der Laan 
<laa...@visucore.com>

My normal key in turn is signed by a lot of different people.

$ gpg --list-sigs 2346C9A6

...

Also, both keys can be found on bitcoin.org in the list of developers, as well
as linked on the download page:

This is *most likely* the mempool, but is just not reported correctly.

In the meantime you can mitigate the mempool growth by setting `-mintxfee`, see
https://github.com/bitcoin/bitcoin/blob/v0.11.0/doc/release-notes.md#transaction-flooding

This will be the default in 0.11.1 and 0.10.3. 0.12.0 will have better mempool 
management, as well as more precise reporting (as paveljanik already mentions.)

[bitcoin-dev] ALERT: Vulnerability in UPnP library used by Bitcoin Core

2015-10-12 Thread Wladimir J. van der Laan via bitcoin-dev 
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA512


TL;DR disable UPnP in Bitcoin Core as soon as possible, if you still have it 
enabled.

Upgrading to 0.11.1rc2 or 0.10.3rc2 will also solve the issue, as they bundle a 
newer libupnpc (as well as disable upnp usage by default.) However these 
versions are still in the release candidate cycle, there is some risk in using 
test versions.

See https://bitcoin.org/en/alert/2015-10-12-upnp-vulnerability for details

I'll interpret the question as "why is the Bitcoin Core software still <1.0.0". 
Bitcoin the currency doesn't have a version, the block/transaction versions are 
at v3/v1 respectively, and the highest network protocol version is 70011. 

Mostly because we don't use the numbers as a signaling mechanism. They just 
count up, every half year.

Otherwise, one'd have to ask hard questions like 'is the software mature enough 
to be called 1.0.0', which would lead to long arguments, all of which would 
eventually lead to nothing more than potentially increasing a number. We're 
horribly stressed-out as is.

In principle, "feature freeze" means that any large code changes will no longer 
go into 0.12, unless fixing critical bugs. 

I'm not keen on postponing 0.12 for such reasons - after the HK workshop I'm 
sure that it will take some development/testing/review before code makes it 
into anything. Apart from that there's a good point to decouple consensus 
changes from Bitcoin Core major releases.

We've seen lot of release date drift due to "this and this change needs to make 
it in" in the past, that was a major reason to switch to a time-based instead 
of feature-based release schedule.

We can always do a 0.12.1.

There appears to be common agreement on that.

The only source of some controversy is how to deploy: versionbits versus
IsSuperMajority. I think the versionbits proposal should first have code
out there for longer before we consider it for concrete softforks. Haste-ing
along versionbits because CLTV is wanted would be risky.

As you say, the underlying code has been merged for months in master, and #6351
seems to have had quite some eyes on it already.

It does need to be made sure that the backports are correct, however.
Although the tests do provide some assurance, I think those two pulls
require more review.

After they are merged, a 0.10.3 and 0.11.1 release can be rolled out (with RC
cycle).

[bitcoin-dev] Bitcoin Core 0.12.0 release schedule

2015-09-24 Thread Wladimir J. van der Laan via bitcoin-dev 
Hello all,

The next major release of Bitcoin Core, 0.12.0 is planned for the end of the 
year. Let's propose a more detailed schedule:

2015-11-01
---
- Open Transifex translations for 0.12
- Soft translation string freeze (no large or unnecessary changes)
- Finalize and close translation for 0.10

2015-12-01
---
- Feature freeze
- Translation string freeze

In December at least I will probably not get much done code-wise (Scaling 
Bitcoin Hongkong, 32C3, end of year festivities, etc), and I'm sure I'm not the 
only one, so let's leave that for last pre-RC bugfixes and polishing.

2016-01-06
---
- Split off `0.12` branch from `master`
- Start RC cycle, tag and release `0.12.0rc1`
- Start merging for 0.13 on master branch

2016-02-01
---
- Release 0.12.0 final (aim)

[bitcoin-dev] Weekly development meetings on IRC: schedule

2015-09-22 Thread Wladimir J. van der Laan via bitcoin-dev 
Hello,

There was overwhelming response that weekly IRC meetings are a good thing.

Thanks to the doodle site we were able to select a time slot that everyone 
(that voted) is available:

Thursday 19:00-20:00 UTC, every week, starting September 24 (next Thursday)

I created a shared Google Calendar here:
https://www.google.com/calendar/embed?src=MTFwcXZkZ3BkOTlubGliZjliYTg2MXZ1OHNAZ3JvdXAuY2FsZW5kYXIuZ29vZ2xlLmNvbQ

The timezone of this calendar is Reykyavik (Iceland) which is UTC+0. However, 
you can use the button on the lower right to add the calendar to your own 
calendar, which will then show the meeting in your own timezone.

See you then,

Wladimir

I think scheduling the meeting in UTC (=Iceland time) makes sense 
internationally because different locales have different DST or no DST at all, 
so all in all that makes it more complex. It's true that this can make a 
convenient time less convenient half of the year, for some people, but I don't 
think there's a time that works for everyone anyway...

As long as it's an open system, one can't require a specific license for 
everything added to the chain.

You could of course make the BIP advisory, but I'm not sure what that would 
help. You still wouldn't have any certainty what license the contents of block
