Cassandra

Cassandra is the Radix test network for sharded Cerberus consensus, named after the Greek prophet.

Cerberus Whitepaper & Academic Validation

Peer-reviewed paper on Cerberus consensus published in the Journal of Systems Research (JSys), June 2023.

Consensus Evolution at Radix

The journey from Tempo to Cerberus to Xi'an: how Radix's consensus mechanisms evolved over a decade of research.

eMunie

eMunie was Dan Hughes' 2012 project that evolved into Radix — a decade-long journey to scalable DLT.

Flexathon

The Flexathon was Radix's internal hackathon stress-testing scalability ideas before publishing Cerberus.

hyperscale-rs

hyperscale-rs is a community-led Rust implementation of the Cerberus consensus protocol, paralleling RDX Works' official implementation.

Hyperscale: 500K TPS Public Test

In January 2026, Radix publicly demonstrated 500,000 sustained TPS and 800,000 peak TPS on commodity AWS hardware using 128 shards, confirming linear scalability.

Radix Economic Model

The Radix economic model balances 300M XRD annual emissions with transaction fees and component royalties to sustain long-term network security.

Tempo (Consensus Mechanism)

Tempo was Radix's first consensus mechanism powering the Olympia mainnet, later replaced by Cerberus.
