Chia’s Alpha Testnet

Alpha testnet introduces the first version of Chialisp, Chia’s smart transaction programming language. The Smart Transactions currently available are: atomic swaps, authorized payees, recoverable wallets, multisig wallets, and rate-limited wallet. Bram has more on Chialisp.

Alpha testnet also introduces Chia’s blockchain consensus layer which includes a full node, farmer and timelord. The blockchain is alpha and does not yet support transactions. Here are some additional thoughts on the alpha chia blockchain.

Since this is an alpha release, you may want to review the release errata.
