Sui Network, a layer-1 blockchain created by ex-Meta (nee Facebook) engineers got a step closer to going live by announcing it has opened its testnet – a place where the viability of the technology can get a more thorough examination.

The testnet “Wave 1” will be used for validators and full nodes to “improve decentralized coordination + incident response, and identify a core group of operators who have experience in deploying, monitoring, and debugging,” the company shared over Twitter.
