Compatibility

Microsoft ended support for Windows XP on April 8th, 2014,
an OS initially released in 2001. This means that not even critical security
updates will be released anymore. Without security updates, using a bitcoin
wallet on a XP machine is irresponsible at least.

In addition to that, with 0.12.x there have been varied reports of Bitcoin Core
randomly crashing on Windows XP. It is not clear
what the source of these crashes is, but it is likely that upstream
libraries such as Qt are no longer being tested on XP.

We do not have time nor resources to provide support for an OS that is
end-of-life. From 0.13.0 on, Windows XP is no longer supported. Users are
suggested to upgrade to a newer version of Windows, or install an alternative OS
that is supported.

No attempt is made to prevent installing or running the software on Windows XP,
you can still do so at your own risk, but do not expect it to work: do not
report issues about Windows XP to the issue tracker.

From 0.13.1 onwards OS X 10.7 is no longer supported. 0.13.0 was intended to work on 10.7+,
but severe issues with the libc++ version on 10.7.x keep it from running reliably.
0.13.1 now requires 10.8+, and will communicate that to 10.7 users, rather than crashing unexpectedly.

Notable changes

Segregated witness soft fork

Segregated witness (segwit) is a soft fork that, if activated, will
allow transaction-producing software to separate (segregate) transaction
signatures (witnesses) from the part of the data in a transaction that is
covered by the txid. This provides several immediate benefits:

• Elimination of unwanted transaction malleability: Segregating the witness
    allows both existing and upgraded software to calculate the transaction
    identifier (txid) of transactions without referencing the witness, which can
    sometimes be changed by third-parties (such as miners) or by co-signers in a
    multisig spend. This solves all known cases of unwanted transaction
    malleability, which is a problem that makes programming Bitcoin wallet
    software more difficult and which seriously complicates the design of smart
    contracts for Bitcoin.
• Capacity increase: Segwit transactions contain new fields that are not
    part of the data currently used to calculate the size of a block, which
    allows a block containing segwit transactions to hold more data than allowed
    by the current maximum block size. Estimates based on the transactions
    currently found in blocks indicate that if all wallets switch to using
    segwit, the network will be able to support about 70% more transactions. The
    network will also be able to support more of the advanced-style payments
    (such as multisig) than it can support now because of the different weighting
    given to different parts of a transaction after segwit activates (see the
    following section for details).
• Weighting data based on how it affects node performance: Some parts of
    each Bitcoin block need to be stored by nodes in order to validate future
    blocks; other parts of a block can be immediately forgotten (pruned) or used
    only for helping other nodes sync their copy of the block chain.  One large
    part of the immediately prunable data are transaction signatures (witnesses),
    and segwit makes it possible to give a different "weight" to segregated
    witnesses to correspond with the lower demands they place on node resources.
    Specifically, each byte of a segregated witness is given a weight of 1, each
    other byte in a block is given a weight of 4, and the maximum allowed weight
    of a block is 4 million.  Weighting the data this way better aligns the most
    profitable strategy for creating blocks with the long-term costs of block
    validation.
• Signature covers value: A simple improvement in the way signatures are
    generated in segwit simplifies the design of secure signature generators
    (such as hardware wallets), reduces the amount of data the signature
    generator needs to download, and allows the signature generator to operate
    more quickly.  This is made possible by having the generator sign the amount
    of bitcoins they think they are spending, and by having full nodes refuse to
    accept those signatures unless the amount of bitcoins being spent is exactly
    the same as was signed.  For non-segwit transactions, wallets instead had to
    download the complete previous transactions being spent for every payment
    they made, which could be a slow operation on hardware wallets and in other
    situations where bandwidth or computation speed was constrained.
• Linear scaling of sighash operations: In 2015 a block was produced that
    required about 25 seconds to validate on modern hardware because of the way
    transaction signature hashes are performed.  Other similar blocks, or blocks
    that could take even longer to validate, can still be produced today.  The
    problem that caused this can't be fixed in a soft fork without unwanted
    side-effects, but transactions that opt-in to using segwit will now use a
    different signature method that doesn't suffer from this problem and doesn't
    have any unwanted side-effects.
• Increased security for multisig: Bitcoin addresses (both P2PKH addresses
    that start with a '1' and P2SH addresses that start with a '3') use a hash
    function known as RIPEMD-160.  For P2PKH addresses, this provides about 160
    bits of security---which is beyond what cryptographers believe can be broken
    today.  But because P2SH is more flexible, only about 80 bits of security is
    provided per address. Although 80 bits is very strong security, it is within
    the realm of possibility that it can be broken by a powerful adversary.
    Segwit allows advanced transactions to use the SHA256 hash function instead,
    which provides about 128 bits of security  (that is 281 trillion times as
    much security as 80 bits and is equivalent to the maximum bits of security
    believed to be provided by Bitcoin's choice of parameters for its Elliptic
    Curve Digital Security Algorithm [ECDSA].)
• More efficient almost-full-node security Satoshi Nakamoto's original
    Bitcoin paper describes a method for allowing newly-started full nodes to
    skip downloading and validating some data from historic blocks that are
    protected by large amounts of proof of work.  Unfortunately, Nakamoto's
    method can't guarantee that a newly-started node using this method will
    produce an accurate copy of Bitcoin's current ledger (called the UTXO set),
    making the node vulnerable to falling out of consensus with other nodes.
    Although the problems with Nakamoto's method can't be fixed in a soft fork,
    Segwit accomplishes something similar to his original proposal: it makes it
    possible for a node to optionally skip downloading some blockchain data
    (specifically, the segregated witnesses) while still ensuring that the node
    can build an accurate copy of the UTXO set for the block chain with the most
    proof of work.  Segwit enables this capability at the consensus layer, but
    note that Bitcoin Core does not provide an option to use this capability as
    of this 0.13.1 release.
• Script versioning: Segwit makes it easy for future soft forks to allow
    Bitcoin users to individually opt-in to almost any change in the Bitcoin
    Script language when those users receive new transactions.  Features
    currently being researched by Bitcoin Core contributors that may use this
    capability include support for Schnorr signatures, which can improve the
    privacy and efficiency of multisig transactions (or transactions with
    multiple inputs), and Merklized Abstract Syntax Trees (MAST), which can
    improve the privacy and efficiency of scripts with two or more conditions.
    Other Bitcoin community members are studying several other improvements
    that can be made using script versioning.

Activation for the segwit soft fork is being managed using BIP9
versionbits.  Segwit's version bit is bit 1, and nodes will begin
tracking which blocks signal support for segwit at the beginning of the
first retarget period after segwit's start date of 15 November 2016.  If
95% of blocks within a 2,016-block retarget period (about two weeks)
signal support for segwit, the soft fork will be locked in.  After
another 2,016 blocks, segwit will activate.

For more information about segwit, please see the segwit FAQ, the
segwit wallet developers guide or BIPs 141, 143,
144, and 145.  If you're a miner or mining pool
operator, please see the versionbits FAQ for information about
signaling support for a soft fork.

Null dummy soft fork

Combined with the segwit soft fork is an additional change that turns a
long-existing network relay policy into a consensus rule. The
OP_CHECKMULTISIG and OP_CHECKMULTISIGVERIFY opcodes consume an extra
stack element ("dummy element") after signature validation. The dummy
element is not inspected in any manner, and could be replaced by any
value without invalidating the script.

Because any value can be used for this dummy element, it's possible for
a third-party to insert data into other people's transactions, changing
the transaction's txid (called transaction malleability) and possibly
causing other problems.

Since Bitcoin Core 0.10.0, nodes have defaulted to only relaying and
mining transactions whose dummy element was a null value (0x00, also
called OP_0).  The null dummy soft fork turns this relay rule into a
consensus rule both for non-segwit transactions and segwit transactions,
so that this method of mutating transactions is permanently eliminated
from the network.

Signaling for the null dummy soft fork is done by signaling support
for segwit, and the null dummy soft fork will activate at the same time
as segwit.

For more information, please see BIP147.

Low-level RPC changes

• importprunedfunds only accepts two required arguments. Some versions accept
    an optional third arg, which was always ignored. Make sure to never pass more
    than two arguments.

Linux ARM builds

With the 0.13.0 release, pre-built Linux ARM binaries were added to the set of
uploaded executables. Additional detail on the ARM architecture targeted by each
is provided below.

The following extra files can be found in the download directory or torrent:

• bitcoin-${VERSION}-arm-linux-gnueabihf.tar.gz: Linux binaries targeting
    the 32-bit ARMv7-A architecture.
• bitcoin-${VERSION}-aarch64-linux-gnu.tar.gz: Linux binaries targeting
    the 64-bit ARMv8-A architecture.

ARM builds are still experimental. If you have problems on a certain device or
Linux distribution combination please report them on the bug tracker, it may be
possible to resolve them. Note that the device you use must be (backward)
compatible with the architecture targeted by the binary that you use.
For example, a Raspberry Pi 2 Model B or Raspberry Pi 3 Model B (in its 32-bit
execution state) device, can run the 32-bit ARMv7-A targeted binary. However,
no model of Raspberry Pi 1 device can run either binary because they are all
ARMv6 architecture devices that are not compatible with ARMv7-A or ARMv8-A.

Note that Android is not considered ARM Linux in this context. The executables
are not expected to work out of the box on Android.

[How It Works]

I have decided to close down the website. The project and this thread remains open for whoever wishes to run their own site.


Today I am announcing another project of mine.

Bitcoin Tipping Addresses lets you enter in a BIP 32 Extended Public Key or a list of addresses and it will give you some code that you can embed on any website, forum, github, or Reddit. This code will always show the next address in the list that has not received any Bitcoin. It lets you not need to reuse addresses for receiving donations.

The website is https://bittipaddress.com

How It Works

You simply enter a BIP 32 Extended Public key or a list of addresses that you want to use. Then you get code that you can embed on any website, forum, github, or reddit. This code links back to the server which will either display the correct address or provide a redirect to the Bitcoin URI of the latest empty address.

You can also change the addresses afterwards if necessary. You will receive an ID and a password which will allow you to edit the parameters of your unit.

Embedded code

There are three codes that you can embed. Here are examples of the three. Currently only HTML will show the actual address. The BBCode and Reddit ones will only show a link to a Bitcoin URI which will open the wallet for the user.

HTML (websites and most Markdowns):

Code:

<iframe src="http://bittipaddress.com/bittipaddr/addressfor/da7ir8dl" style="border:none;" scrolling="no"></iframe>

BBCode (forums):

Compatibility

Microsoft ended support for Windows XP on April 8th, 2014,
an OS initially released in 2001. This means that not even critical security
updates will be released anymore. Without security updates, using a bitcoin
wallet on a XP machine is irresponsible at least.

In addition to that, with 0.12.x there have been varied reports of Bitcoin Core
randomly crashing on Windows XP. It is not clear
what the source of these crashes is, but it is likely that upstream
libraries such as Qt are no longer being tested on XP.

We do not have time nor resources to provide support for an OS that is
end-of-life. From 0.13.0 on, Windows XP is no longer supported. Users are
suggested to upgrade to a newer verion of Windows, or install an alternative OS
that is supported.

No attempt is made to prevent installing or running the software on Windows XP,
you can still do so at your own risk, but do not expect it to work: do not
report issues about Windows XP to the issue tracker.

Notable Changes

Database cache memory increased

As a result of growth of the UTXO set, performance with the prior default
database cache of 100 MiB has suffered.
For this reason the default was changed to 300 MiB in this release.

For nodes on low-memory systems, the database cache can be changed back to
100 MiB (or to another value) by either:

• Adding `dbcache=100` in bitcoin.conf
• Changing it in the GUI under `Options → Size of database cache`

Note that the database cache setting has the most performance impact
during initial sync of a node, and when catching up after downtime.


bitcoin-cli: arguments privacy

The RPC command line client gained a new argument, -stdin
to read extra arguments from standard input, one per line until EOF/Ctrl-D.
For example:

    

Code:

$ src/bitcoin-cli -stdin walletpassphrase
    mysecretcode
    120
    ..... press Ctrl-D here to end input
    $

It is recommended to use this for sensitive information such as wallet
passphrases, as command-line arguments can usually be read from the process
table by any user on the system.


C++11 and Python 3

Various code modernizations have been done. The Bitcoin Core code base has
started using C++11. This means that a C++11-capable compiler is now needed for
building. Effectively this means GCC 4.7 or higher, or Clang 3.3 or higher.

When cross-compiling for a target that doesn't have C++11 libraries, configure with
./configure --enable-glibc-back-compat ... LDFLAGS=-static-libstdc++.

For running the functional tests in `qa/rpc-tests`, Python3.4 or higher is now
required.


Linux ARM builds

Due to popular request, Linux ARM builds have been added to the uploaded
executables.

The following extra files can be found in the download directory or torrent:

• bitcoin-${VERSION}-arm-linux-gnueabihf.tar.gz: Linux binaries for the most
    common 32-bit ARM architecture.
• bitcoin-${VERSION}-aarch64-linux-gnu.tar.gz: Linux binaries for the most
    common 64-bit ARM architecture.
  

ARM builds are still experimental. If you have problems on a certain device or
Linux distribution combination please report them on the bug tracker, it may be
possible to resolve them.

Note that Android is not considered ARM Linux in this context. The executables
are not expected to work out of the box on Android.


Compact Block support (BIP 152)

Support for block relay using the Compact Blocks protocol has been implemented
in PR 8068.

The primary goal is reducing the bandwidth spikes at relay time, though in many
cases it also reduces propagation delay. It is automatically enabled between
compatible peers.

BIP 152

As a side-effect, ordinary non-mining nodes will download and upload blocks
faster if those blocks were produced by miners using similar transaction
filtering policies. This means that a miner who produces a block with many
transactions discouraged by your node will be relayed slower than one with
only transactions already in your memory pool. The overall effect of such
relay differences on the network may result in blocks which include widely-
discouraged transactions losing a stale block race, and therefore miners may
wish to configure their node to take common relay policies into consideration.


Hierarchical Deterministic Key Generation

Newly created wallets will use hierarchical deterministic key generation
according to BIP32 (keypath m/0'/0'/k').
Existing wallets will still use traditional key generation.

Backups of HD wallets, regardless of when they have been created, can
therefore be used to re-generate all possible private keys, even the
ones which haven't already been generated during the time of thebackup.
Attention: Encrypting the wallet will create a new seed which requires
a new backup!

Wallet dumps (created using the dumpwallet RPC) will contain the deterministic
seed. This is expected to allow future versions to import the seed and all
associated funds, but this is not yet implemented.

HD key generation for new wallets can be disabled by -usehd=0. Keep in
mind that this flag only has affect on newly created wallets.
You can't disable HD key generation once you have created a HD wallet.

There is no distinction between internal (change) and external keys.

HD wallets are incompatible with older versions of Bitcoin Core.

Pull request, BIP 32


Segregated Witness

The code preparations for Segregated Witness ("segwit"), as described in BIP 141, BIP 143, BIP 144, and BIP 145 are
finished and included in this release.  However, BIP 141 does not yet specify
activation parameters on mainnet, and so this release does not support segwit
use on mainnet.  Testnet use is supported, and after BIP 141 is updated with
proposed parameters, a future release of Bitcoin Core is expected that
implements those parameters for mainnet.

Furthermore, because segwit activation is not yet specified for mainnet,
version 0.13.0 will behave similarly as other pre-segwit releases even after a
future activation of BIP 141 on the network.  Upgrading from 0.13.0 will be
required in order to utilize segwit-related features on mainnet (such as signal
BIP 141 activation, mine segwit blocks, fully validate segwit blocks, relay
segwit blocks to other segwit nodes, and use segwit transactions in the
wallet, etc).


Mining transaction selection ("Child Pays For Parent")

The mining transaction selection algorithm has been replaced with an algorithm
that selects transactions based on their feerate inclusive of unconfirmed
ancestor transactions.  This means that a low-fee transaction can become more
likely to be selected if a high-fee transaction that spends its outputs is
relayed.

With this change, the -blockminsize command line option has been removed.

The command line option -blockmaxsize remains an option to specify the
maximum number of serialized bytes in a generated block.  In addition, the new
command line option -blockmaxweight has been added, which specifies the
maximum "block weight" of a generated block, as defined by BIP 141 (Segregated Witness).

In preparation for Segregated Witness, the mining algorithm has been modified
to optimize transaction selection for a given block weight, rather than a given
number of serialized bytes in a block.  In this release, transaction selection
is unaffected by this distinction (as BIP 141 activation is not supported on
mainnet in this release, see above), but in future releases and after BIP 141
activation, these calculations would be expected to differ.

For optimal runtime performance, miners using this release should specify
-blockmaxweight on the command line, and not specify -blockmaxsize.
Additionally (or only) specifying -blockmaxsize, or relying on default
settings for both, may result in performance degradation, as the logic to
support -blockmaxsize performs additional computation to ensure that
constraint is met.  (Note that for mainnet, in this release, the equivalent
parameter for -blockmaxweight would be four times the desired
-blockmaxsize.  See BIP 141 for additional details.)

In the future, the -blockmaxsize option may be removed, as block creation is
no longer optimized for this metric.  Feedback is requested on whether to
deprecate or keep this command line option in future releases.


Reindexing changes

In earlier versions, reindexing did validation while reading through the block
files on disk. These two have now been split up, so that all blocks are known
before validation starts. This was necessary to make certain optimizations that
are available during normal synchronizations also available during reindexing.

The two phases are distinct in the Bitcoin-Qt GUI. During the first one,
"Reindexing blocks on disk" is shown. During the second (slower) one,
"Processing blocks on disk" is shown.

It is possible to only redo validation now, without rebuilding the block index,
using the command line option -reindex-chainstate (in addition to
-reindex which does both). This new option is useful when the blocks on disk
are assumed to be fine, but the chainstate is still corrupted. It is also
useful for benchmarks.


Removal of internal miner

As CPU mining has been useless for a long time, the internal miner has been
removed in this release, and replaced with a simpler implementation for the
test framework.

The overall result of this is that setgenerate RPC call has been removed, as
well as the -gen and -genproclimit command-line options.

For testing, the generate call can still be used to mine a block, and a new
RPC call generatetoaddress has been added to mine to a specific address. This
works with wallet disabled.


New bytespersigop implementation

The former implementation of the bytespersigop filter accidentally broke bare
multisig (which is meant to be controlled by the permitbaremultisig option),
since the consensus protocol always counts these older transaction forms as 20
sigops for backwards compatibility. Simply fixing this bug by counting more
accurately would have reintroduced a vulnerability. It has therefore been
replaced with a new implementation that rather than filter such transactions,
instead treats them (for fee purposes only) as if they were in fact the size
of a transaction actually using all 20 sigops.


Low-level P2P changes

• The optional new p2p message "feefilter" is implemented and the protocol
    version is bumped to 70013. Upon receiving a feefilter message from a peer,
    a node will not send invs for any transactions which do not meet the filter
    feerate. BIP 133
• The P2P alert system has been removed in PR #7692 and the alert P2P message
    is no longer supported.
• The transaction relay mechanism used to relay one quarter of all transactions
    instantly, while queueing up the rest and sending them out in batch. As
    this resulted in chains of dependent transactions being reordered, it
    systematically hurt transaction relay. The relay code was redesigned in PRs
    #7840 and #8082, and now always batches transactions announcements while also
    sorting them according to dependency order. This significantly reduces orphan
    transactions. To compensate for the removal of instant relay, the frequency of
    batch sending was doubled for outgoing peers.
• Since PR #7840 the BIP35 mempool command is also subject to batch processing.
    Also the mempool message is no longer handled for non-whitelisted peers when
    NODE_BLOOM is disabled through -peerbloomfilters=0.
• The maximum size of orphan transactions that are kept in memory until their
    ancestors arrive has been raised in PR #8179 from 5000 to 99999 bytes. They
    are now also removed from memory when they are included in a block, conflict
    with a block, and time out after 20 minutes.
• We respond at most once to a getaddr request during the lifetime of a
    connection since PR #7856.
• Connections to peers who have recently been the first one to give us a valid
    new block or transaction are protected from disconnections since PR #8084.

Low-level RPC changes

• RPC calls have been added to output detailed statistics for individual mempool
    entries, as well as to calculate the in-mempool ancestors or descendants of a
    transaction: see getmempoolentry, getmempoolancestors, getmempooldescendants.
• gettxoutsetinfo UTXO hash (hash_serialized) has changed. There was a divergence between
    32-bit and 64-bit platforms, and the txids were missing in the hashed data. This has been
    fixed, but this means that the output will be different than from previous versions.
• Full UTF-8 support in the RPC API. Non-ASCII characters in, for example,
    wallet labels have always been malformed because they weren't taken into account
    properly in JSON RPC processing. This is no longer the case. This also affects
    the GUI debug console.
    - Asm script outputs replacements for OP_NOP2 and OP_NOP3
  
    - OP_NOP2 has been renamed to OP_CHECKLOCKTIMEVERIFY by BIP 65
  
    - OP_NOP3 has been renamed to OP_CHECKSEQUENCEVERIFY by BIP 112
  
    - The following outputs are affected by this change:
  
      - RPC getrawtransaction (in verbose mode)
      - RPC decoderawtransaction
      - RPC decodescript
      - REST /rest/tx/ (JSON format)
      - REST /rest/block/ (JSON format when including extended tx details)
      - bitcoin-tx -json
  
• The sorting of the output of the getrawmempool` output has changed.
• New RPC commands: generatetoaddress, importprunedfunds, removeprunedfunds, signmessagewithprivkey,
    getmempoolancestors, getmempooldescendants, getmempoolentry,
    createwitnessaddress, addwitnessaddress.
• Removed RPC commands: setgenerate, getgenerate.
• New options were added to fundrawtransaction: includeWatching, changeAddress, changePosition and feeRate.

Low-level ZMQ changes

• Each ZMQ notification now contains an up-counting sequence number that allows
    listeners to detect lost notifications.
    The sequence number is always the last element in a multi-part ZMQ notification and
    therefore backward compatible. Each message type has its own counter.
    PR #7762.

If there is a language that you can translate for but isn't listed, please let us know and it can be added.

[Hosting and Source]

After talking with goatpig, we have decided to launch a new website for the Open Source Armory that goatpig has continued development on.

Visit the site at http://btcarmory.com/

The website will announce new releases and important announcements as well as host documentation for Armory. The releases are still hosted on the github page and the official contact for goatpig is still on this forum.

Pull requests to update the site are welcome. Just clone the source, make your changes, and submit a PR to the gh-pages branch.

Hosting and Source
The site is currently hosted using github pages. The source for the site is available at https://github.com/goatpig/BitcoinArmory/tree/gh-pages.

Credits and license
The site uses the jekyll now theme by Barry Clark. The source code for the site is available under the MIT License.

Recently I have been seeing a newly created account creating a post with just the words

Quantum code review

and that being a link to somewhere (some linkedin page IIRC). The title of the post is usually nonsense.

Can we get the anti-spam bot on this? It's getting annoying to report those every single time.

For example: https://bitcointalk.org/index.php?topic=1588435.0;topicseen#msg15951451

I made one, because why not? It's on freenode, #bitcoin-armory. Web interface link: https://webchat.freenode.net/?channels=bitcoin-armory.

The channel is for discussion about the software, upcoming changes, and technical discussion. No Tech Support is allowed in the channel. Those are more easily handled on the forum.

Is there a list of all of the forum boards here on Bitcointalk? Ideally it would be one that is always up to date so that I can do some futureproofing to my account price estimator site.

After months of testing, coding, and work, Segregated Witness has finally been merged into Bitcoin Core: https://github.com/bitcoin/bitcoin/pull/8149.

Now that it has been merged, there are a few things that need to be done before release, and many things that will come after Segwit that builds upon it: https://bitcoincore.org/en/2016/06/24/segwit-next-steps/.

I'm thinking about (going to try) using the Google Prediction API: https://cloud.google.com/prediction/ to detect spam. However, in order to do so, it needs to be trained to know what spam and not spam looks like. Would it be possible for the mods or admins to give me a file with all of the posts that were deleted for being spam and the topic they were posted in?

If that is not possible, could the mods, as you delete spam posts, put them into this spreadsheet: https://docs.google.com/spreadsheets/d/16frPDZkHcg-WYuWtj_Qqkc0fzPtoj4kBKrjpCrlU9h4/edit?usp=sharing on the sheet labeled SPAM.

Users can also help. If you see a post that you think is spam, you can put it into the above spreadsheet. You can also put posts that you think are good and not spam into the sheet on the sheet labeled NOT SPAM. If you put things into the spreadsheet, it would be best not to include quoted stuff.

I know that this sounds like a lot of work for users and mods, but I also think that having a prediction model for spam would be a beneficial thing for this forum.

If anyone wants to help me here, feel free and please do so. If anyone has any suggestions for me for any part of this project, please let me know.

[Usage]

Today I am announcing the Bitcoin Transaction Fee Booster.

This is my response to the constant complaints about users who are waiting a long time for confirmations. The program gives the user two options to increase the fee of their unconfirmed transactions, Replace-By-Fee for senders and Child Pays For Parent for receivers. The software will take the raw hex of a transaction, ask the user for some information, and create an unsigned transaction which can be signed outside of the program. Then the signed transaction can be broadcast from the software.

Usage
Using the Fee Booster is very simple and follows a wizard with step by step instructions.

Download the zip file from https://github.com/achow101/FeeBooster/releases. Extract everything inside to the same folder. Double click the FeeBooster.jar file to start the program.

First you enter the raw hex of the transaction and choose whether you sent or received it. Then, if you sent the transaction, you will be brought to a page which asks you to set the increased fee of the RBF transaction and the output to deduct the fee from. If you received, you will be brought to a page to select the output you want to spend from, the address to send to, and the fee for the child transaction. The next page is the unsigned transaction that the software made and you must take this to your own wallet to be signed. Lastly, the signed transaction can be broadcast from the software.

How it works
The program uses https://bitcoinfees.21.co/ to calculate the optimal fee for the transaction. It also uses blockcypher.com's api for retrieving some other information for the transaction. To send the transaction, the program uses the BitcoinJ library.

Security
The program, as of now, does not take your private keys. This is a planned feature to allow signing within the program, but currently that does not happen. The software produces an unsigned transaction which can be independently verified to see that it makes the right transaction. It will also display the transaction id of the broadcasted transaction and that can be verified to be the transaction that the user intended. This software is not malicious

Source code
The Fee Booster is open source. The source code is available at https://github.com/achow101/FeeBooster. Pull requests are welcome

Disclaimer
This software comes as is and may have some bugs. I am not responsible if you happen to lose any of your coins when using this software. Always check the transaction before you send it.

Why?

I have 9 AWS codes that I would like to sell. Each one is good for $100. They are all from the 2015 MLH Season so only one code can be used per account. They expire December 31st, 2017.

Price is 0.025 BTC per code. PM me to buy. You must either go first or use an escrow.
