rollup-node

Rollup-node is an optional module for DappLink Appchain. It integrates five type of DAs, and six DA interfaces, which are Anytrust, Celestia, EigenDA, NearDA, and EIP-4844. AnytrustDA is divided into two types: single anytrust DAS and anytrust das committee

Users can roll up data to a specified DA and receive a receipt. They can also retrieve corresponding data from the specified DA based on the receipt.

Users can set configuration options for all five DAs simultaneously, or configure only the DAs that they intend to use among the five.

To use the rollup module, the corresponding DA needs to be prepared in advance. For example, Anytrust requires an off-chain DA service to be run beforehand, and NearDA requires a Near account, contract, and private key to be prepared in advance.

We provide APIs and SDKs to offer users a convenient way to interact.

da_type corresponding to different DAs

DA	da_type

celestia	1
eigenda	2
eip-4844	3
nearda	4
anytrust(DAS committee)	5

Run Rollup Node

• Submodule

  run git submodule update --init --recursive --remote to update submodule

• Additional Considerations for NearDA

  Because NearDA uses a C code library near_da_rpc_sys.a, we need to place this library file in the specified location before compilation. The library file and related documentation are located in the ./c-lib directory.

• Compilation & Run

  make build and ./rollupNode rollup-node --rpcAddress localhost:9000 --apiAddress localhost:9001

  or

  go build and ./rollup-node --rpcAddress localhost:9000 --apiAddress localhost:9001

API & SDK

• API

  When starting the rollup-node, you need to set --apiAddress as the listening address for the web server.

  • rollup & retrieve

    route	type	args	comment
    /api/v1/rollup-with-type	post	{"da_type": 4,"data":"base64 string"}	Rollup data to a specified DA
    /api/v1/retrieve-with-type	post	{"da_type": 4, "args":"rollup receipt"}	Retrieve data from specified DA with rollup receipt

• SDK When starting the rollup-node, you need to set --rpcAddress as the listening address for the web server.

  • new a sdk: rollupSdk, err := sdk.NewRollupSdk(rpcAddress)
  • rollup: rollupSdk.RollupWithType(dataByte, daType)
  • retrieve: rollupSdk.RetrieveWithType(daType, rollupReceipt)
