/**
 * Contract responsible for managing the states and the updates of L2 network.
 * There will be a trusted sequencer, which is able to send transactions.
 * Any user can force some transaction and the sequencer will have a timeout to add them in the queue.
 * The sequenced state is deterministic and can be precalculated before it's actually verified by a zkProof.
 * The aggregators will be able to verify the sequenced state with zkProofs and therefore make available the withdrawals from L2 network.
 * To enter and exit of the L2 network will be used a PolygonZkEVMBridge smart contract that will be deployed in both networks.
 * It is advised to use timelocks for the admin address in case of Validium since if can change the dataAvailabilityProtocol

/**
 * @dev This is a base contract to aid in writing upgradeable contracts, or any kind of contract that will be deployed
 * behind a proxy. Since proxied contracts do not make use of a constructor, it's common to move constructor logic to an
 * external initializer function, usually called `initialize`. It then becomes necessary to protect this initializer
 * function so it can only be called once. The {initializer} modifier provided by this contract will have this effect.
 *
 * The initialization functions use a version number. Once a version number is used, it is consumed and cannot be
 * reused. This mechanism prevents re-execution of each "step" but allows the creation of new initialization steps in
 * case an upgrade adds a module that needs to be initialized.
 *
 * For example:
 *
 * [.hljs-theme-light.nopadding]
 * ```
 * contract MyToken is ERC20Upgradeable {
 *     function initialize() initializer public {
 *         __ERC20_init("MyToken", "MTK");
 *     }
 * }
 * contract MyTokenV2 is MyToken, ERC20PermitUpgradeable {
 *     function initializeV2() reinitializer(2) public {
 *         __ERC20Permit_init("MyToken");
 *     }
 * }
 * ```
 *
 * TIP: To avoid leaving the proxy in an uninitialized state, the initializer function should be called as early as
 * possible by providing the encoded function call as the `_data` argument to {ERC1967Proxy-constructor}.
 *
 * CAUTION: When used with inheritance, manual care must be taken to not invoke a parent initializer twice, or to ensure
 * that all initializers are idempotent. This is not verified automatically as constructors are by Solidity.
 *
 * [CAUTION]
 * ====
 * Avoid leaving a contract uninitialized.
 *
 * An uninitialized contract can be taken over by an attacker. This applies to both a proxy and its implementation
 * contract, which may impact the proxy. To prevent the implementation contract from being used, you should invoke
 * the {_disableInitializers} function in the constructor to automatically lock it when it is deployed:
 *
 * [.hljs-theme-light.nopadding]
 * ```
 * /// @custom:oz-upgrades-unsafe-allow constructor
 * constructor() {
 *     _disableInitializers();
 * }
 * ```

 * @dev Implementation of the {IERC165} interface.
 *
 * Contracts that want to implement ERC165 should inherit from this contract and override {supportsInterface} to check
 * for the additional interface id that will be supported. For example:
 *
 * ```solidity
 * function supportsInterface(bytes4 interfaceId) public view virtual override returns (bool) {
 *     return interfaceId == type(MyInterface).interfaceId || super.supportsInterface(interfaceId);
 * }
 * ```
 *
 * Alternatively, {ERC165Storage} provides an easier to use but more expensive implementation.

 * @dev This contract implements a proxy that is upgradeable through an associated {ProxyAdmin} instance.
 *
 * To avoid https://medium.com/nomic-labs-blog/malicious-backdoors-in-ethereum-proxies-62629adf3357[proxy selector
 * clashing], which can potentially be used in an attack, this contract uses the
 * https://blog.openzeppelin.com/the-transparent-proxy-pattern/[transparent proxy pattern]. This pattern implies two
 * things that go hand in hand:
 *
 * 1. If any account other than the admin calls the proxy, the call will be forwarded to the implementation, even if
 * that call matches the {ITransparentUpgradeableProxy-upgradeToAndCall} function exposed by the proxy itself.
 * 2. If the admin calls the proxy, it can call the `upgradeToAndCall` function but any other call won't be forwarded to
 * the implementation. If the admin tries to call a function on the implementation it will fail with an error indicating
 * the proxy admin cannot fallback to the target implementation.
 *
 * These properties mean that the admin account can only be used for upgrading the proxy, so it's best if it's a
 * dedicated account that is not used for anything else. This will avoid headaches due to sudden errors when trying to
 * call a function from the proxy implementation. For this reason, the proxy deploys an instance of {ProxyAdmin} and
 * allows upgrades only if they come through it. You should think of the `ProxyAdmin` instance as the administrative
 * interface of the proxy, including the ability to change who can trigger upgrades by transferring ownership.
 *
 * NOTE: The real interface of this proxy is that defined in `ITransparentUpgradeableProxy`. This contract does not
 * inherit from that interface, and instead `upgradeToAndCall` is implicitly implemented using a custom dispatch
 * mechanism in `_fallback`. Consequently, the compiler will not produce an ABI for this contract. This is necessary to
 * fully implement transparency without decoding reverts caused by selector clashes between the proxy and the
 * implementation.
 *
 * NOTE: This proxy does not inherit from {Context} deliberately. The {ProxyAdmin} of this contract won't send a
 * meta-transaction in any way, and any other meta-transaction setup should be made in the implementation contract.
 *
 * IMPORTANT: This contract avoids unnecessary storage reads by setting the admin only during construction as an
 * immutable variable, preventing any changes thereafter. However, the admin slot defined in ERC-1967 can still be
 * overwritten by the implementation logic pointed to by this proxy. In such cases, the contract may end up in an
 * undesirable state where the admin slot is different from the actual admin.
 *
 * WARNING: It is not recommended to extend this contract to add additional external functions. If you do so, the
 * compiler will not check that there are no selector conflicts, due to the note above. A selector clash between any new
 * function and the functions declared in {ITransparentUpgradeableProxy} will be resolved in favor of the new one. This
 * could render the `upgradeToAndCall` function inaccessible, preventing upgradeability and compromising transparency.
