Hosting an anchor service¶
It is currently not possible to run your own CAS. Once Ceramic opens mainnet to the public, this will be possible.
By default, every Ceramic node automatically uses a CAS provided by the community based on the node's network configuration. You do not need any additional setup. In the future, nodes will be able to specify which CAS they use.
Free CAS services are offered by 3Box Labs for Ceramic developers.
For nodes connected to Mainnet, they will use a Mainnet CAS which generates anchor records using the Ethereum Mainnet blockchain (
eip155:1) and communicates over the
/ceramic/mainnet libp2p topic.
For nodes connected to Clay Testnet, they will use a Clay Testnet CAS which generates anchor records using the Ethereum Rinkeby or Ropsten blockchains and communicates over the
/ceramic/testnet-clay libp2p topic.
For nodes connected to Dev Unstable, they will use a Dev Unstable CAS which generates anchor records using the Ethereum Rinkeby or Ropsten blockchains and communicates over the
/ceramic/dev-unstable libp2p topic.
