UpgradeableProxyADFS

Overview

  1. Author

    Aneta Tsvetkova

  2. Notice

    Implements an upgradeable proxy for the Blocksense

    Aggregated Data Feed Store (ADFS) contract.

  3. Developer notes

    Non-management calls are delegated to the contract address stored in

    IMPLEMENTATION_SLOT, which is upgradeable by the admin stored in the

    ADMIN_SLOT.

    Storage layout:

    * Management space: [0 to 2**128-2**116)

    0x0000 - latest blocknumber (used by the implementation)

    0x0001 - implementation slot (used by this contract)

    0x0002 - admin slot (used by this contract)

    ... - additional management space reserved for ADFS

    * ADFS data space: [2**128-2**116 to 2**160)

    This contract intentionally deviates from the EIP-1967 slot scheme.

    It was co-designed with ADFS to accomodate its custom low-level

    storage management requirements.

    Note that this deviation has implications on storage isolation and

    upgrade safety.
