3 years ago, my co-founder
@0xASK
and I built a DeFi protocol, Rift Finance.
In our attempt to bring Rift from L1 to L2s, it became clear that existing options to deploy smart contracts across rollups forced us to make undesirable trade-offs.
We built Omni to solve these

Our engineering team has really stepped up to the plate. We started as a small team with a big vision, and have grown our eng team with awesome contributors from Matter Labs,

this is Omni's why

Omni solves this by using abci++ to move the mempool to the execution side so we can directly leverage the EVM mempool, rather than using CometBFT for application layer txns

"Sovereign" rollups are a new term being pushed by Celestia, where DA can live wherever and canonical state is not determined by a zk-verifier or fraud proof, but simply social consensus. This is not actually a rollup, inherits no security, it's an L1 with validator set size 1.

Great post from Vitalik, this is why we settle everything back to L1 – Omni doesn't rely on some subjective notion of reality.
Because rollups post their "canonical" state roots to L1, we can always verify Omni relayer signatures against those state roots

Low ego is probably the most important characteristic of any team member, regardless of role
The best community-builders have 0 haughtiness toward newcomers no matter who they are:
Pure 100% welcoming energy → loyal community
The worst community-builders are relentless gatekeepers:
"You must be this tall to ride" → people resent you and want to see you fail
