Zero Knowledge Optimistic Rollup
Layer-2 for Securities and NFTs
Securities & NFTs
Upstream runs on Ráneum mainnet trading securities (ERC-20) and NFTs (ERC-721) with 2-second transaction finality and zero gas fees
A commit-chain providing Ethereum-based finality which aids recovery in case of catastrophic failure
Developers run unmodified EVM contracts and Ethereum transactions on layer-2 and leverage Ethereum’s layer-1 security
Ráneum deployments generate trading fees
Ráneum runs an Automated Market Maker inside a Solidity-based transparent orderbook on Upstream
Ráneum smart contracts gain fiat on-ramp to US Dollars and an inter-chain bridge that accepts USDC from Ethereum
Ráneum is built by Horizon Fintex, with a world-class team of researchers, engineers, and Ethereum enthusiasts

In Norse mythology, Rán is a goddess of the sea associated with a net which she uses to bring seagoers together
Ráneum integrates with Ethereum and a growing list of EVM smart contract applications and services
Ráneum operates an Ethereum layer-1 smart contract where it publishes its layer-2 transaction hashes as rolling attestations to the state of the chain
Ráneum runs the complete set of Ethereum smart contracts used to operate the Upstream stock and NFT exchange for ERC-20 and ERC-721 issuance and secondary trading
Ráneum runs an Ethereum smart contract registry for publicly-anonymous identities that allow key pair-based accounts make public claims on layer-1 and layer-2 about the legitimacy of their ownership
Ráneum implements the IBFT 2.0 Proof of Authority protocol with immediate finality, delivering Byzantine fault tolerance by operating multiple validators. To achieve resilience and high availability, validators and their constituent parts - compute, storage, networking and data resources - are distributed across physically and logically separated, sub 2ms low latency regional zones. Each validator zone comprises of multiple datacenters with independent power source, network and cooling. In addition, to facilitate comprehensive disaster recovery in the event of a regional zone failure, Ráneum employs a DRaaS which replicates validators to separate global locations.
Ráneum shares the same wallet framework as Ethereum layer-1 which means that wallets on Ráneum mainnet can be used and shared with Ethereum mainnet using MetaMask.
