The KRNL mock node is a simulated version of the production node intended for experimentation until the production release. Under the hood, it is connected to a local Hardhat node, with most of the important RPC calls under the eth namespace ported over. Additionally, the node is extended with a new namespace called krnl, which introduces two additional RPC methods.
Forwards the call from the client to the token-authority then returns the response to the client. Technically it's just a proxy call.
Similar to eth_sendRawTransaction, but instead of immediately broadcasting the transaction, it pauses to check the end of the transaction's input data field for additional data. This additional data is concatenated with a 32-byte padded : sign and encoded within the transactions, facilitating the execution of respective FaaS services.
Rigth now only a mock KYT and an EigenLayer KYT FaaS service are implemented directly in the node, but you can get creative and implement your own services.
The AVS based KYT will fail with a KYT failed for address message unless the KYT process was done in the KYTTaskManager contract of the AVS. For it to work, the local anvil chain, an aggregator and an operator have to be started and the /send-task-KYT endpoint has to be called with the correct address in the request body.
To further understand the EigenLayer KYT AVS see.
For the local run the .env file is not required.
