  First-party client libraries and node/CLI binaries for the Spacemesh
  protocol. The full node (go-spacemesh) is the primary implementation; smcli
  is the wallet/genesis CLI; the @spacemesh npm packages support wallet/tx
  construction in JS/TS. The company web domains are parked, but the code and
  release artifacts remain published under the spacemeshos GitHub org.
