RADIX WikiRADIX Wiki

Most of Radix exists because one problem was refused for thirteen years: a single-threaded ledger cannot serve the world’s financial traffic, and bigger or faster blocks buy time rather than remove the ceiling. This section holds the designs tried against it, from eMunie in 2013 through Tempo and Cerberus to Cassandra. The abandoned ones are kept because each names a failure mode the next design had to survive.

Hyperscale, and what the tests measured

The current line is Hyperscale. In January 2026 the Radix Foundation sustained more than 500,000 transactions per second, peaking above 700,000, on commodity AWS instances of four cores and 16 GB each. That measured the Foundation’s implementation: it was not a measurement of Cerberus as specified, and the braided cross-shard consensus in the Cerberus paper has not shipped in any implementation. hyperscale-rs, the community-built Rust implementation led by flightofthefox of proven.network, is the leading candidate to deliver Xi’an.
