IUM uses Proof-of-Stake to reach consensus.

Therefore, we need active participants (nodes or Clients) to propose, verify, and guarantee the validity of blocks. In exchange, honest participants will receive economic rewards.

Importantly, as a participant, you need to post at least 200,000 IUM as collateral; in other words, you need to pledge some of your funds. The only way to become a participant is by making a one-way IUM transaction to the margin contract of the DEVIUM execution layer. The DEVIUM chain (consensus layer) operates in parallel to track the activity of all participants.
