Store Data

Submit a plain, unencrypted payload to Palliora’s Data Availability layer. This is the simplest DA write there is, no Guardian group, no encryption, no Compute Contract. It’s what a Publisher does before anyone can build an agreement on top of what they published, see Data Availability for what happens to the data once it’s submitted.

// store-data.mjs
import { init, getKeyring, submitData } from "@palliora.org/chainsdk";

async function main() {
  init({
    pallioraWs: process.env.PALLIORA_WS ?? "wss://staging.manas-rpc.palliora.org",
  });

  const keyring = await getKeyring();
  const account = keyring.addFromUri("//Bob"); // dev-only, replace for real use

  await submitData(account, "hello from palliora-docs");
  console.log("Submitted. Check your terminal's debug output (init with debug: true) for the transaction hash.");
}

main().catch((err) => {
  console.error("Failed:", err.message);
  process.exit(1);
});

A current limitation worth knowing

submitData doesn’t return a locator for what you just submitted, no block number, no reference ID. If you need to find your data again afterward, track the submission yourself: pass init({ debug: true }) to log the transaction hash, or build the transaction with signAndSend directly instead of going through submitData, which does return { blockNumber, index, hash }:

import { getApi, signAndSend } from "@palliora.org/chainsdk";

const api = await getApi();
const tx = api.tx.dataAvailability.submitData("hello from palliora-docs");
const receipt = await signAndSend(tx, account);
console.log("Landed at block", receipt.blockNumber, "index", receipt.index);

Once you have a block height, the SDK’s indexer client can fetch the blob back:

import { getBlob } from "@palliora.org/chainsdk";
// indexerClient: see SDK Reference for how it's configured
const blob = await getBlob(indexerClient, receipt.blockNumber);

For data that needs to stay private

This guide submits plaintext. If the data itself needs to be hidden, not just coordinated through the network, you need a Guardian group and threshold-encrypted submission (submitTEDataWithCipher plus registerDataAgreement), which is the same cryptographic groundwork covered in Encrypted Compute.
