# Blob sharing protocol

Implementation of trusted blob sharing protocol. Supports submissions via a permissionless API authenticated via ECDSA signatures. Publishers pre-pay credits via on-chain transfers. For complete rationale and design decisions, refer to https://hackmd.io/@dapplion/blob_sharing



```

Usage: blobshare [OPTIONS] --database-url 

Options:

  -p, --port 

          Name of the person to greet [env: PORT=] [default: 5000]

  -b, --bind-address 

          Number of times to greet [env: BIND_ADDRESS=] [default: 127.0.0.1]

      --eth-provider 

          JSON RPC endpoint for an ethereum execution node [env: ETH_PROVIDER=] [default: ws://127.0.0.1:8546]

      --eth-provider-interval 

          JSON RPC polling interval in miliseconds, used for testing [env: ETH_PROVIDER_INTERVAL=]

      --starting-block 

          First block for service to start accounting [env: STARTING_BLOCK=] [default: 0]

      --data-dir 

          Directory to persist anchor block finalized data [env: DATA_DIR=] [default: ./data]

      --mnemonic 

          Mnemonic for tx sender. If not set a random account will be generated. TODO: UNSAFE, handle hot keys better [env: MNEMONIC=]

      --panic-on-background-task-errors

          FOR TESTING ONLY: panic if a background task experiences an error for a single event [env: PANIC_ON_BACKGROUND_TASK_ERRORS=]

      --finalize-depth 

          Consider blocks `finalize_depth` behind current head final. If there's a re-org deeper than this depth, the app will crash and expect to re-sync on restart [env: FINALIZE_DEPTH=] [default: 64]

      --max-pending-transactions 

          Max count of pending transactions that will be sent before waiting for inclusion of the previously sent transactions. A number higher than the max count of blobs per block should not result better UX. However, a higher number risks creating transactions that can become underpriced in volatile network conditions [env: MAX_PENDING_TRANSACTIONS=] [default: 6]

      --database-url 

          Database URL to mysql DB with format `mysql://user:password@localhost/test` [env: DATABASE_URL=]

      --metrics

          Enable serving metrics [env: METRICS=]

      --metrics-port 

          Metrics server port. If it's the same as the main server it will be served there [env: METRICS_PORT=] [default: 9000]

      --metrics-bearer-token 

          Require callers to the /metrics endpoint to add Bearer token auth [env: METRICS_BEARER_TOKEN=]

      --metrics-push-url 

          Enable prometheus push gateway to the specified URL [env: METRICS_PUSH_URL=]

      --metrics-push-interval-sec 

          Customize push gateway frequency [env: METRICS_PUSH_INTERVAL_SEC=] [default: 15]

      --metrics-push-basic-auth 

          Provide Basic Auth for push gateway requests [env: METRICS_PUSH_BASIC_AUTH=]

      --metrics-push-format 

          Format to send push gateway metrics [env: METRICS_PUSH_FORMAT=] [default: protobuf] [possible values: protobuf, plain-text]

  -h, --help

          Print help

  -V, --version

          Print version

```
