Quarkslab has completed their audit of the code! 🚀
I’ll be assembly with them Friday to debate their findings. After that, they’ll work on releasing the audit report in a weblog publish, which I sit up for sharing with you all.
Because you’ll have the ability to learn the complete report as soon as they share their weblog publish, I gained’t dive too deeply into the findings right here. However at a fast look:
There was one crucial difficulty discovered that resulted from a mistake whereas merging the MWEB code & v0.21.1 code collectively. So when copying the adjustments into the newest launch code, I missed a small, however essential line of validation code that might’ve been exploited by a malicious attacker to trigger severe disruptions to the chain 😳
This tells us…
We might actually profit from higher practical check protection round our validation logic to verify we’d catch comparable points ourselves in future releases.
We should always take into consideration including some processes we are able to comply with to reduce the potential for this occurring. That would imply documenting all adjustments, or having 2 individuals carry out the merge individually then evaluating outcomes, or a change to how we method the code opinions.
The audit was a very good concept (thanks Quarkslab!)
There have been additionally some smaller findings, and a few nice recommendations for the way we might enhance the standard and security of the code. General, they had been impressed with the code high quality, which was thrilling to listen to 🥳
v0.21.1 (Taproot) Launch
The launch course of 5 we inherited from bitcoin may be fairly painful. It makes use of gitian 4 to construct repeatable and deterministic binaries from the supply code. Which means that a number of individuals can all construct the code on completely different machines (and even completely different working methods) and nonetheless get the identical precise launch binaries. We will then all examine the outcomes after which signal the discharge, certifying that all of us agree that the revealed launch is protected & correct.
There’s a number of magic concerned to make this work, which ends up in a time-consuming & usually irritating expertise (particularly for n00bs like me). So I actually dragged my ft on this one 😬
. I lastly compelled myself to push by way of this a couple of days in the past, and after combating with some outdated scripts, was in a position to construct all the binaries efficiently. I’ll end signing these tomorrow and hand them off for the opposite builders to repeat the construct & confirm outcomes.
After plenty of guarantees after which take-backs, I’ve lastly determined to launch a binary that permits non-technical customers to check out the MWEB testnet. I solely have the home windows launch out there proper now, however I’ll work on getting binaries for Mac OS X on Friday. Linux customers can construct their very own, as a result of I’m drained 😝
Hyperlink: MWEB Testnet Launch 26
Right here’s my gpg key 8 should you’d prefer to confirm the binaries first (you need to). I’ll add directions on how to try this on the discharge web page when I’ve a while.
There’s no installer, as a result of I didn’t need anybody by chance changing their precise litecoin pockets, so to make use of it:
- Obtain (and confirm) the zip file
- Extract the
- Discover and run
litecoin-qt.exefrom contained in the bin folder
This can default to utilizing the MWEB testnet, which you’ll inform by the off-colored emblem and the
[mwebtest] within the title bar. These use mwebtest cash, not precise litecoin cash. So pleeease don’t attempt to use it with actual cash.
You’ll both must mine a block to get mwebtest cash (you may CPU mine a block very quickly), or discover somebody to offer you some. If anybody is keen to setup a faucet, I’ve bought a ton of cash you may have 🙂
Additionally, if somebody looks like writing a information for learn how to create stealth addresses, ship to and obtain from them, and all the enjoyable stuff that goes together with it, you’d be my new favourite individual.
You’re just about again to simply ready on me once more ⏱
whereas I end making use of audit recommendations after which pushing by way of the tedious technique of merging, coordinating closing opinions, writing launch notes, and eventually kicking off the beloved gitian builds. I don’t know precisely how lengthy that may take, however rumor has it that it will increase by a full day for each individual that asks me 😜
What a protracted journey this has been 😅
