How Does kOS Work?

This page is dedicated to illustrating how the KRNL Operating System, kOS, works when a dApp submits a transaction to a smart contract, and how smart contracts receive responses from kernels.

Keep in mind that figures are high-level concepts.

---

1. A dApp sends a request to the KRNL node

Step 1: dApp to KRNL node

2. The KRNL node sends a request to the list of predefined kernels

Step 2: KRNL node to list of kernels

3. Each kernel will be executed until all selected kernels are completed

Step 3: Kernels are executing

4. Responses from kernels will be sent back to the KRNL node

Step 4: Kernels send responses to the KRNL node

5. The node sends received responses to Token Authority

Step 5: The KRNL node sends kernels' responses to TA

6. Token Authority examines the responses and passes them back to the node

Step 6: TA sends back to KRNL node

7. The KRNL node provides responses from Token Authority to a dApp

Step 7: KRNL node to dApp

8. A dApp is able to submit a transaction to a smart contract

Step 8: dApp submits transaction to smart contract

A smart contract will receive the responses from the selected kernels and Token Authority.

It will then make the final decision whether the transaction should go through (succeed) or not (failure).
