The V27 beta testing has entered its fourth round, as announced by gr0vity in the Discord channel on July 9.

"Beta testing for V27 continues. This addresses some issues identified in previous rounds mainly when using RocksDB backend. During this phase of testing, we continue to focus on confirmation times and overall system stability as we move closer to the Release Candidate (RC) phase."

So far, results have been positive, with improved performance for transaction confirmations and bootstrapping nodes even facing a high load of transactions, simulating "spam." The nano developer and beta tester gr0vity also reported some of these improvements on the same day.

"I did some testing on confirmation durations with 100 additional bootstrapping nodes.

You can see that the additional bootstrapping nodes have no negative impact on confirmation durations. This shows that we successfully met our target for V27, which aimed to ensure priority blocks confirm quickly even under spam conditions. In all tested situations, the median confirmation duration is around 1 second.

Previously, similar tests on V26 resulted in extended confirmation times for priority blocks, exceeding 15 seconds most of the time. However, there still is an impact on throughput with additional nodes, which drops from ~350cps to ~80cps. This will be addressed in an upcoming version via traffic shaping and a redesign of the network topology."

He also explained that these tests were using a single bucket of transactions.

The beta testing continues, and everyone is welcome to take part in the tests before the final release.

Gustav Schauwecker officially announced RsNano, a working nano node written in 100% Rust, after two years of intensive work and development.

Gustav ported the C++ nano-node and has streamed part of the process on his YouTube channel, with a special stream celebrating this announcement on May 28.

However, there is still more work to do before the node is officially launched for public testing. You can read more about the missing pieces and next steps in this blog post.

"So what’s next? Of course all of those missing features have to be implemented in Rust. Also the RsNano code repository is currently 200 commits behind the C++ repository. This will be the focus for the next weeks. Then, shortly after V27 is released, I’m going to release RsNano 1.0-alpha for public testing, which will be equivalent to V27." - Gustav Schauwecker
