The latest in a series of Ethereum 2.0 testnets, called Spadina, launched on Tuesday with mixed success.
Spadina was proposed as a short-lived “dress rehearsal” for the mainnet launch process, signaling that Ethereum 2.0 Phase 0 is getting ever closer. The network launched on Sept. 29 at 12 P.M. UTC, and was intended to last for only 72 hours.
