Allowlist

Exposes an onlyAllowedNode modifier that restricts unallowed nodes from calling permissioned contract functions

To be used with BaseConsumer._receiveCompute to restrict responding nodes

In the future, this list can be abstracted out to a contract that enables dynamic list declarations (registry)

State Variables

node address => is allowed node

Access list applied via onlyAllowedNode modifier

Forced private visibility to disallow modifications outside of _updateAllowlist

Read getter exposed via isAllowedNode()

mapping(address => bool) private allowedNodes;

Allow only nodes in the allowedNodes set

modifier onlyAllowedNode(address node);

Parameters

Name	Type	Description
`node`	`address`	calling node to checkin `allowedNodes` set

Initializes new Allowlist

constructor(address[] memory initialAllowed);

Parameters

Name	Type	Description
`initialAllowed`	`address[]`	array of initially-allowed node addresses

Update allowedNodes

Does not validate nodes.length == status.length

function _updateAllowlist(address[] memory nodes, bool[] memory statuses) internal;

Parameters

Name	Type	Description
`nodes`	`address[]`	array of node addresses to update
`statuses`	`bool[]`	array of status(es) to update where index corresponds to index in nodes array

Check whether a node is allowed

function isAllowedNode(address node) external view returns (bool);

Parameters

Name	Type	Description
`node`	`address`	address to check for set inclusion

Returns

Name	Type	Description
`<none>`	`bool`	true if node is in Allowlist & its status is set to `true` (allowed), else false

Thrown by onlyAllowedNode() if node address is not in allowedNodes set
