3 seconds. 200 blocks. Chain ID 890. Those three values sent me into a completely different part of @MarsChainDAO. They come from the network configuration, and they led me to three technical layers I wanted to understand properly: Deimos consensus, validator authorization, and checkpoint infrastructure. The 3-second Deimos period defines the block-production timing. The 200-block epoch establishes a larger consensus interval, while Chain ID 890 identifies the network at the protocol level. But the numbers are only the entry point. The Deimos implementation goes further. It performs block-signature verification, checks recent signers, handles checkpoints, and retrieves validator information from the validator contract. That means validator state isn't just sitting inside a dashboard. It can feed directly into the consensus process that determines who is authorized to participate in block signing. I find this separation important: Contract state → Validator set → Authorization → Signature → Block Then there is the checkpoint layer. The public implementation includes checkpoint handling inside the consensus architecture, adding another mechanism for tracking and validating chain state as the blockchain progresses. And because MarsChain is EVM compatible, the execution environment sits alongside these consensus components rather than replacing them. So the architecture I currently map is: EVM execution ↓ Transactions & contracts ↓ Validator state ↓ Deimos consensus ↓ Signed blocks + checkpoints This is probably the most technical angle I've explored on MarsChain so far. Instead of starting with the token, I started with the parameters that make the blockchain itself operate. And those three numbers turned out to be a much better entry point than I expected.
