Cosmos, a new public-private network of blockchains goes live

Amongst all the hype in the cryptocurrency space, a handful of permissionless initiatives stand out such as Polkadot and DFINITY. Cosmos is one of them, and the network officially went live late last night. Cosmos tackles many of the issues that plague public blockchains, including three of the biggest: scalability, interoperability and finality.
