Jepsen's latest distributed systems safety report covers Radix DLT 1.0-beta.35.1 through 1.0.2. We found stale, aborted, and intermediate reads, as well as the partial or total loss of committed transactions. Transactions could also hang indefinitely.

RDX Works (the makers of Radix DLT) states that all safety issues as well as the problem with indefinite transactions have been resolved as of Radix DLT 1.1.0.
For Radix DLT folks concerned about 16 vs. 50 transactions per second--I wouldn't worry about that at all. In benchmark terms those are basically the same number. As mentioned in the report, we're talking about different hardware, a different network, and different workloads. :-)
