Ionian Client

Go implementation for client to interact with storage nodes in Ionian network.

SDK

Application could use a node/Client instance to interact with storage node via JSON RPC. Especially, use Client.KV() for KV operations.

CLI

Run go build under the root folder to compile the executable binary.

Global options

      --gas-limit uint     Custom gas limit to send transaction
      --gas-price uint     Custom gas price to send transaction
  -h, --help               help for ionian-client
      --log-force-color    Force to output colorful logs
      --log-level string   Log level (default "info")

Deploy contract

./ionian-client deploy --url <blockchain_rpc_endpoint> --key <private_key> --bytecode <bytecode_hex_or_json_file>

Generate test file

To generate a file for test purpose, especially with a fixed file size or random file size (without --size option):

./ionian-client gen --size <file_size_in_bytes>

Upload file

./ionian-client upload --url <blockchain_rpc_endpoint> --contract <ionian_contract_address> --key <private_key> --node <storage_node_rpc_endpoint> --file <file_path>

Download file

./ionian-client download --node <storage_node_rpc_endpoint> --root <file_root_hash> --file <output_file_path>

To download file from multiple storage nodes in parallel, --node option supports to specify multiple comma separated URLs, e.g. url1,url2,url3.

If you want to verify the merkle proof of downloaded segment, please specify --proof option.
