[dev] 1.10 and beyond

After the extremely short update on Sunday, now 1.10 RC 1 is out the door I wanted to write a bit more on what we're doing, what happens next, and the importance of 1.10.
So, as you're probably aware, 1.10 is our first major release in over a year. There was a 1.9, however development of it was abandoned in the middle of this year, as the process used was simply infeasible to follow (too much manual checking of changes from Bitcoin Core, unfortunately). It brings in a huge number of changes, but there's a few worth emphasising:
Most of the security fixes are also being made available in 1.8.3, although the fixes for CVE-2015-3641 are not readily compatible with that release, so it's only to be used where upgrading to 1.10 is not an option.
Final releases of both should be out at the end of this month, but both clients have been heavily tested, and generally I'd encourage upgrading to 1.10 now if you can, and it's then fairly straight-forward to install the final release over it once it's out.
Post-1.10, Bitcoin Core 0.12 should be branched early next year, and will likely form the basis for Dogecoin Core 1.11. Meanwhile langer_hans has been working on the Android client and updating it to use bitcoinj and libdohj, and we're hammering out bugs in libdohj. So far, that's going fairly well, and while we don't have an ETA, once out it should vastly reduce the time to update to new versions of bitcoinj (because we're extending it, rather than rewriting it). Multidoge HD will also follow the same development model, and hopefully we'll see it update to bitcoinj 0.14 at some point, enabling us to move forward with adding libdohj support.

The Monero Missives (weekly report) - September 16th, 2014

Original post is here
Monero Missives
September 15th, 2014
Hello, and welcome to our twelfth Monero Missive! This is our first Missive after a bit of a break whilst we thwarted two related blockchain attacks. Nonetheless, we have not sat by idly, we have been finalising and completing a brand new aspect of Monero designed to protect your privacy now and in the future: the Monero Research Lab
Major Updates
  1. The Monero Research Lab is an open collective and a multi-faceted academic group focused on the ongoing improvement of Monero. Membership is not fixed, and comes and goes as researchers become interested in Monero. This isn't a group focused on the addition of "features" to Monero, but rather the analysis and improvement of the underlying core of Monero to make sure that the theories and cryptography behind Monero continue to remain robust and sound. With that in mind, we are proud to announce the release of the first two publications out of the Monero Research Lab: MRL-0001 - A Note on Chain Reactions in Traceability in CryptoNote 2.0 - this is a research bulletin that investigates how a chain reaction could weaken the blockchain resistance properties of CryptoNote's ring signatures if low mixin values are consistently chosen MRL-0002 - Counterfeiting via Merkle Tree Exploits within Virtual Currencies Employing the CryptoNote Protocol - in this research bulletin we investigate how the block 202612 attack occurred and what it exploited, and also covers the permanent fix we have put in place
  2. This week Friday we're going to have our second #Monero-Dev Fireside Chat this week Friday, September 19th, 2014, at 10:00 EST which is 14:00 UTC and 16:00 UTC +2. For a full table of the time zones you can refer to this image, or you can use this online tool to add your city and make sure you have the correct starting time. Please note that this is a developer event, and so most of the focus will be from that perspective.
  3. To pick up where we left off with our last Missive, we are also happy to announce the availability of Monero merchandise on the Monero Gear store, powered by Zazzle. The advantage of us using Zazzle is that it is on-demand and we never have to worry about print runs or stock or anything. In return we get 15% of each sale as a "royalty" that will go towards enabling further Monero development, although Zazzle do not (yet!) accept Bitcoin or Monero. We hope to add new designs to the store on a regular basis. You can check the store out here: http://www.zazzle.com/monerogear* or take a peek at some of the new designs right here
  4. We are also pleased to announce the release of URS, a Monero project written in Go that allows you to sign messages using ring signatures as part of a group. The signature can be verified, but it cannot be determined which one of the signatories in the group did the actual signing (just like Monero uses for transactional unlinkability!). You can take a look at the project here: https://github.com/monero-project/urs, and the Bitcointalk thread dedicated to the project is here: https://bitcointalk.org/index.php?topic=768499.0
  5. We have a new tagged release, 0.8.8.4, available for download (binaries: Windows, Mac, Linux, FreeBSD). This adds the following features: Testnet: we now have an operating testnet. When using bitmonerod or simplewallet you can now use the --testnet flag to use testnet instead of mainnet. Feel free to run a mining node or just a testnet node, we will be setting up email alerts for testnet nodes when an update is pending (although having a few older testnet nodes on the network won't hurt testing). FreeBSD Compatability: Monero now works on FreeBSD out the box. We will add it to the ports tree soon. At the moment compilation is no different from regular Linux and Unix compilation, and the same dependencies apply. GPG commits: we have begun GPG-signing commits and merges. This is an important step in maintaining the integrity of the codebase, and will ensure that any compromise of our computers or even the github account won't allow a malicious attacker to push code to the repository without the unsigned commits being spotted. Verification can be done by running 'git log --show-signature', which will show and verify signatures. An example of what you should see can be found here Versioning: versioning is a lot easier, now, as tagged releases from 0.8.8.4 onwards will show version-final (eg. 0.8.8.4-final) as their version, and those built between tagged releases will show version-commithash (eg. 0.8.8.4-9088ea1). We expect this will greatly aid in debugging problems, as we can immediately pinpoint the actual version / commit a user is on. Logging: default log levels have been adjusted so that non-critical warnings are now relegated to log-level 1 and above. Apart from the normal reorganisation notifications, the only messages in red that should show up in the daemon are actual errors.
  6. We have slowed down development on the GUI to give us a bit more time to focus on the Monero internals. This is especially important given the recent attack. However, work has not come to a complete halt, and so we wanted to show off a couple of pages from the first start wizard. Bear in mind that these aren't mockups, this is the actual running Qt interface: http://i.imgur.com/jzUvSEP.jpg, http://i.imgur.com/Bj1PTcU.jpg, http://i.imgur.com/oirzi9n.jpg, http://i.imgur.com/ACDmOFJ.jpg
  7. Monero has been added to another exchange, Coin Swap. You can find the market here: https://coin-swap.net/market/XMBTC
Dev Diary
Core: because of all of the rapid changes that we had to merge into master to deal with the aftermath of the block 202612 attack, we have to bring the development branch in sync. At this stage the development branch should not be considered usable until the rebase is complete.
Build: the big change is FreeBSD compatibility, as mentioned above. A more subtle change is that the build will now first look for miniupnpc on the local system, and use that if found. If it fails to find miniupnpc it will fall back to the local copy.
Build: there is a new Makefile target, release-static, that builds statically linked binaries for redistribution. At this stage it forces 64-bit builds, once we have the embedded database working cleanly we can remove this.
Wallet: per-kb fees are nearly complete, and will be deployed to testnet within the next week or so. Once some thorough testing has been done on testnet we can merge this into master, and transaction fees can return to "normal".
Blockchain: this took a bit of a backseat with the blockchain attacks. Now that things are back to some semblance of normality, the first implementation can be written. We have chosen LMDB for the initial implementation, as this will allow us to rapidly write a Berkeley DB interface based off of it (they use similar APIs) and thus have a baseline for performance comparisons.
Core: all non-critical "errors" and warnings have been moved to log-level 1. As a developer, you may find it useful to run log-level 1 or 2 as your default.
Until next week!

(Guide) Upgrade your Bitnodes Hardware to XT

Hey guys, If you have a BITNODES HARDWARE and want to run the new XT Core, I've made some instructions that might help out a little bit.
# XTs build apparently needs libcurl to compile or else configure fails, this wasn't on the bitnodes I have by default. sudo apt-get install curl libcurl4-openssl-dev cd ~ git clone https://github.com/bitcoinxt/bitcoinxt.git cd bitcoinxt git checkout 0.11A ./autogen.sh ./configure --without-gui --without-miniupnpc --disable-wallet # This next step takes alot of RAM, you'll need to shutdown the supervisor and bitcoind process first to clear up some RAM, otherwise you'll get an "internal compiler error". make make check cp src/bitcoind src/bitcoin-cli ~/bin/ # Disables auto updating rm ~/hardware/.current_bitcoind # Reboot so system/supervisobitcoind will come back up cleanly. sudo shutdown -r now

Compatibility

Bitcoin Core is extensively tested on multiple operating systems using
the Linux kernel, macOS 10.8+, and Windows Vista and later.
Microsoft ended support for Windows XP on April 8th, 2014,
No attempt is made to prevent installing or running the software on Windows XP, you
can still do so at your own risk but be aware that there are known instabilities and issues.
Please do not report issues about Windows XP to the issue tracker.
Bitcoin Core should also work on most other Unix-like systems but is not
frequently tested on them.
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.
0.14.2 Change log

Detailed release notes follow. This overview includes changes that affect
behavior, not code moves, refactors and string updates. For convenience in locating
the code changes and accompanying discussion, both the pull request and
git merge commit are mentioned.

RPC and other APIs

P2P protocol and network code
