Mainnet stress test event, Crossfire, includes USD 300,000 validator incentives.

Hong Kong, Dec. 17, 2020 – today announced Crossfire, the Mainnet dry run, aimed at stress testing the network in a practical, real-world setting before public release. Crossfire marks an important milestone and final step in preparation for mainnet. Participating Validators have the opportunity to compete with each other while completing tasks. Winning Validators will share a prize pool of USD 300,000 in CRO rewards.

In the last year, the Chain has received massive support from its community and industry partners. Croeseid, the latest testnet, features a new codebase based on the Cosmos SDK and has achieved great success with 50+ validators deployed and over 800,000 transactions processed.

Kris Marszalek, CEO of, said:

“With the Mainnet production dry run, we are entering the final stretch on the road to go-live. The Crossfire competition for validators with $300,000 in rewards is a critical part of stress testing the network before the much anticipated launch.’

The Cosmos SDK, upon which the Chain is built, promotes scalability, usability and coin interoperability. Cosmos’ inter-blockchain communication (IBC) module allows cross-chain asset transfers and communications that provide strong support for DeFi use cases, a core element of’s product roadmap. Chain mainnet continues to adopt Tendermint Core as its consensus engine, one of the most mature Byzantine-fault tolerant (BFT) consensus engines for building proof-of-stake systems, and its codebase is released on Github here written in the Go programming language.
