The process of contributing data in the Gateway Protocol involves several steps:

  1. File Preparation: The data is encrypted using the Data Owner’s public key and then partitioned into shards and subjected to erasure coding for fault tolerance.

  2. Allocation Creation: The Data Contributor interacts with a smart contract to create a Data Assurance Commitment, specifying storage parameters. Appropriate EDVs are selected, and a storage contract is finalized.

  3. Data Upload: The Data Contributor initiates a WRITE transaction, and the Anchor Node orchestrates the transfer of shards to the assigned EDVs, which issue receipts upon successful reception.

  4. Proof of Storage: EDVs are periodically challenged to provide Proof of Storage. Upon verification, a WRITE_MARKER is recorded, allowing EDVs to claim rewards from the Challenge Pool.

  5. Payment and Token Flow: After a verified challenge response, payment transactions are executed, distributing funds among EDVs, validators, and other participants based on their roles and SLA adherence.

  6. File Retrieval and Management: Data Verifiers can request access by creating a REQUEST transaction, which requires a re-encryption key. The Data Contributor or Owner can perform updates and signal deletion commands through smart contracts.

This streamlined process ensures data security, privacy, and integrity while leveraging encryption, distributed ledger technology, and smart contracts for efficient data lifecycle management in a decentralized environment.
