Dear Bitcoin Community, MultiBit-HD is no longer supported

One of the most common questions we get asked at our support desk is how to easily move funds from a MultiBit-HD Classic or MultiBit-HD wallet to a KeepKey. We are excited to announce a simple utility to do just this. Below are the downloads for supported platforms:

We are pleased to announce We are releasing this as beta due to the nature of the changes we made. There is a slight chance this upgrade might break prior versions of wallet data. If you install this beta, make sure you have access to your wallet words just in case.

We are pleased to announce the next

The latest release of Trezor firmware, v1.3.6, appears to have broken MultiBit-HD's support of Trezor for Windows users. We have already received a pull request to fix this issue, so expect it to be resolved in our next release.

We have received numerous requests for help with MultiBitClassic related to the delay for transactions making themselves into blocks. We wanted to provide some quick pointers to help those that are experiencing this issue.

This marks the beginning of a new chapter for MultiBit-HD, at its new home: KeepKey. Gary Rowe and Jim Burton forged the path this far. Not enough can be said about the achievement these two created with MultiBit-HD. KeepKey is now taking the reins, and our intention is to keep MultiBit-HD great.

The MultiBit-HD team is pleased to announce that KeepKey, LLC, makers of the popular KeepKey hardware wallet, have put in an offer to buy MultiBit-HD which has been accepted. Within a few weeks we will complete the transfer of control over the MultiBit-HD code and website to them and we will step back from further development.

This is a guest post from a security researcher who took a close look at the way that . As part of our here are the details of the attack and what has been done to mitigate it.

On 16 July 2011 Jim pushed the first commit of the MultiBit-HD source code to GitHub. This marked the beginning of a long journey as part of the Bitcoin ecosystem which we would like to share with you today.

We are pleased to announce that our first maintenance release

On 20 June 2015 CoinWallet.eu announced that they would perform a Bitcoin network stress test starting Monday 22 June 2015 and extending over 100 blocks. The stated intention was to discover whether the block size limit of 1MB would, when transaction volume exceeded its capacity, allow for quick recovery of the network to normal service.

We are pleased to announce that

The Payment Protocol (BIP 70) is a Bitcoin standard describing how merchants and wallet developers can work together to produce a seamless buying experience using bitcoin. It is supported by MultiBit-HD Beta 8 and higher.

We are pleased to announce the Beta 8 release of MultiBit-HD. This release includes support for the Bitcoin standard "Payment Protocol" (BIP 70). This standard enables merchants to provide signed payment requests with lots of features like memos, refund addresses, receipts etc.

Thanks to the sterling work of GitHub user "gurnec" during Beta testing an incompatibility between MultiBit-HD and other hierarchical deterministic (HD) wallets was discovered indicating that they are not BIP 32 compliant. This is important because "BIP 32 compliance" means that a user of one wallet can easily migrate to another in a safe manner simply by providing their "wallet words" during a restore process.

As you may have noticed, we've stepped up the frequency of our beta release iteration cycle. Consequently the MultiBit-HD Beta 7 is now .

Following rapidly in the footsteps of Beta 5 the MultiBit-HD Beta 6 is now .

We are proud to announce that MultiBit-HD Beta 5 is now .

Recently a user raised Issue #661 on GitHub where unfortunately they lost a total of 1.43033675 bitcoin. This blog article provides details of the forensics we performed to find out what happened and our recommendations for action to try to prevent this happening again.

It has been a while since our last blog post so we thought we'd give you an update on our progress.

In the MultiBit-HD 0.5.18 release there are two changes we have made to improve the safety of your private keys:

What is the best way to provide Bitcoin users with high quality wallet software ? How do the devs get paid ?

is the unofficial name for the CVE-2014-0160 bug with the OpenSSL library which has been shown to reveal private information from affected servers. MultiBit-HD uses SSL to ensure you are downloading from the correct site and .

For most people creating a wallet is the single most important step on their journey into Bitcoin. At MultiBit-HD we have worked hard to make this process as smooth as possible while not sacrificing on security.

We've been asked quite a few times about progress with MultiBit-HD, the replacement for the current MultiBitClassic. To show that we're hard at work for the Bitcoin community here is a sneak preview of MultiBit-HD and some of its many features. If you'd like to join in with testing (and get your name on the contributors list) please get in touch through our support page.

We were asked recently how many downloads there had been of MultiBit-HD since its inception back in April 2011. To answer this Jim went off into the website download stats archive (and various Tweets of important milestones) and discovered that MultiBit-HD has been downloaded over 1.5 million times.

Normally we at MultiBit-HD keep a low profile, but once in a while we like to let people know what we've been doing behind the scenes. Today is one of those days.

Over the past few months we at MultiBit-HD have noticed a few Denial of Service (DoS) attacks taking place against our servers.

Over the course of 3 days in September 2013 the MultiBit-HD team attended the European Bitcoin Conference in Amsterdam.

Bitcoin applications are not like ordinary applications - they handle real money and as such need to be treated with more security precautions than you would otherwise use.

TL;DR There were an estimated 73,200+ downloads of MultiBit-HD in April 2013.

In December 2012 I (Jim) created an acronym for the main items of work that I wanted to add to MultiBit-HD. 'CCEESHH' was the acronym, so let's see how far we have progressed:

A few members of the MultiBit-HD community have asked us for advice regarding the current security status of Java since there has been a lot of confusion and misinformation out on the Web. Here is what we know and how it relates to your use of MultiBit-HD.
