Designed on First Principles

Trustless Security

Nume does not make any trust assumptions on top of Ethereum. If you trust Ethereum, you can trust Nume.

Data Availability

Every user is revealed sufficient information about each settlement to be able to withdraw their funds trustlessly and directly from the contract at any time.

Non-custodial

The Nume Protocol is non-custodial and guarantees that a settlement with unauthorized changes to users’ balances will not succeed on-chain.

Decentralized Governance

The protocol is governed by validators. Any changes to the Nume off chain state verification algorithm requires validators’ signature.

Best of rollup worlds

With Optimistic rollups(ORs), transactions are inexpensive but users need to wait 2 weeks to withdraw funds. Zk-rollups enable quick exit but are computationally expensive. Nume achieves costs lower than ORs while enabling ZK-like fast liquidity exit. Our protocol is based on a validity-proof system that is not a zk-rollup.

EVM addressability

The Nume Protocol is fully EVM-addressable and sits behind an EVM wrapper, which means your favourite Web3 wallets and domain names will just work! Most of our delightful features though can only be accessed by wallets that have chosen to support a dedicated integration.

Block explorer

Nume’s block explorer allows anyone to inspect transactions within a block. However, we will maintain privacy of the transactions of users who have opted in for privacy preserving. Their addresses will not be revealed and require a sender or recipient key to decrypt.
