Sunrise OP DA Server

This repo implements a Sunrise DA Server for Alt-DA mode using generic commitments.

The sunrise-op-da-server connects to a sunrise-node running as a sidecar process.

sunrise da-server accepts the following flags for sunrise storage

    --sunrise.server value             (default: "http://localhost:26658") ($OP_PLASMA_DA_SERVER_SUNRISE_SERVER)
          sunrise server endpoint

    --sunrise.data-shard-count value   (default: 10)                    ($OP_PLASMA_DA_SERVER_SUNRISE_DATA_SHARD_COUNT)
          sunrise data shard count

    --sunrise.parity-shard-count value (default: 10)                    ($OP_PLASMA_DA_SERVER_SUNRISE_PARITY_SHARD_COUNT)
          sunrise parity shard count

The sunrise server endpoint should be set to the sunrise-data backend, usually http://127.0.0.1:8000.

How to run testnet with da-server

Prerequisites

You should use at least the following compatible op* versions when running your chain.

• op-node/v1.9.1
• op-proposer/v1.9.1
• op-batcher/v1.9.1
• Latest version of op-geth

Run Sunrise Node

You can refer the sunrise repo for the setup and running of the sunrise node along with the sunrise-data.

Setup DA server

da-server
      --sunrise.server=http://localhost:8000
      --sunrise.data_shard_count=10
      --sunrise.parity_shard_count=10

Configure Your op-node

• Spin up your OP chain as usual but set --altda.enabled=true and point both op-batcher and op-node to the DA server.
• No configuration changes are required for op-geth or op-proposer.

   Alt-DA (EXPERIMENTAL)

   
    --altda.da-server value                                               ($OP_NODE_ALTDA_DA_SERVER)
          HTTP address of a DA Server
   
    --altda.enabled                    (default: false)                   ($OP_NODE_ALTDA_ENABLED)
          Enable Alt-DA mode
   
    --altda.verify-on-read             (default: true)                    ($OP_NODE_ALTDA_VERIFY_ON_READ)
          Verify input data matches the commitments from the DA storage service

Configure Your Batcher

• Set --altda.enabled=true and --altda.da-service=true.
• Provide the URL for --atlda.da-server=$DA_SERVER_HTTP_URL.

    --altda.da-server value                                               ($OP_BATCHER_ALTDA_DA_SERVER)
          HTTP address of a DA Server
   
    --altda.da-service                 (default: false)                   ($OP_BATCHER_ALTDA_DA_SERVICE)
          Use DA service type where commitments are generated by the DA server
   
    --altda.enabled                    (default: false)                   ($OP_BATCHER_ALTDA_ENABLED)
          Enable Alt-DA mode
   
    --altda.verify-on-read             (default: true)                    ($OP_BATCHER_ALTDA_VERIFY_ON_READ)
          Verify input data matches the commitments from the DA storage service
