The FixĬonsidering the proximity to the planned release date, panic started to set in. Due to the importance of the finding, Charlie generously donated his own money to pay Kurt a well-deserved 0.15 BTC bounty. We are very grateful for Kurt taking the time to study MWEB’s design, and for reaching out to share this attack with us. But the consequences if it did succeed would be very serious, so it was obvious this was something we had to prevent. There are a number of reasons why this attack would fail in practice nearly every time.

tx1 & tx2 dropped and replaced with tx3.

tx3 = spend coin 2 to send 18 LTCs to Alice and 2 LTC back to Bob as Change.

Alice changes tx1 to spend coin 2 instead, keeping the additional 10 LTCs for herself:.

tx2 = spend coin 2 to send 15 LTCs to Charlie (15 LTC Charlie, 5 LTC Change).

tx1 = spend coin 1 to send 8 LTCs to Alice (8 LTC Alice, 2 LTC Change).

Bob creates 2 transactions, 1 to Charlie, and another back to Alice, and sends them at roughly the same time:.

This attack is rather technical, and difficult to understand without first learning all of the crypto behind MWEB. While the attack is difficult to perform in practice, it does allow for theft of funds if the conditions line up just right. Kurt, a long-time GRIN community member, contacted Charlie and I to inform us of a vulnerability in the design for non-interactive transactions.

Pull from Transifex would automatically overwrite them again.This update was written and provided by Litecoin MimbleWimble lead developer David Burkett. Important: We do not accept translation changes as GitHub pull requests because the next Translation process for details on how this works. Translations are periodically pulled from Transifex and merged into the git repository. Translations are converted to Litecoin periodically. We only accept translation fixes that are submitted through Bitcoin Core's Transifex page.

Manual Quality Assurance (QA) TestingĬhanges should be tested by somebody other than the developer who wrote theĬode. The Travis CI system makes sure that every pull request is built for Windows, Linux, and macOS, and that unit/sanity tests are run automatically. These tests can be run (if the test dependencies are installed) with: test/functional/test_runner.py In Python, that are run automatically on the build server. There are also regression and integration tests, written Further details on runningĪnd extending unit tests can be found in /src/test/README.md. (assuming they weren't disabled in configure) with: make check. Other people's pull requests, and remember this is a security-critical project where any mistake might cost peopleĭevelopers are strongly encouraged to write unit tests for new code, and to Please be patient and help out by testing Requests than we can review and test on short notice.
