RChain multi-shard DEX architecture compared to Osmosis on Cosmos / Agoric IBC

[dckc]

• RChain DEX 12-15 22:54
  • gist of english translation

It's a credible architecture, but I see a number of challenges:

• [ ] RChain catch-up with industry norms
  • [ ] mature end-user wallet
  • [ ] validators other than the coop
    • [ ] technical work
    • [ ] business development to get validators operating
• [ ] RChain behavioral types design, implementation, deployment
• [ ] DEX contracts in rholang
  • [ ] application of behavioral types for formal verification
• [ ] cross-shard transactions between RChain shards
  • [ ] protocol design, implementation
  • [ ] business development for cross-shard validators
  • [ ] wallet support
• [ ] shards: business development to get credible set of validators going
  • [ ] economic protocol design for who gets to be a validator - is it permissionless?
• [ ] bridges
  • [ ] protocol design, implementation
  • [ ] if bridge is based on a multi-sig: business development to get credible collection of signers
  • [ ] if not, light client implementation in rholang for each counter-chain
    • [ ] for example, add IBC support to RChain

Meanwhile, based on the multi-chain Cosmos IBC vision developed by Agoric and others, Osmosis (market cap: $6B) already does essentially all of this, except that the DEX "shard" is sequential (4000TPS ceiling) and formal verification is off-chain and only covers layers up to IBC, not the DEX itself:

• [x] Over 20 chains with IBC support
• [x] Osmosis DEX chain with IBC support
  • [x] DEX functionality as Cosmos SDK module (golang)
  • [x] credible set of validators running
  • [x] 24h Trading Volume: $28M
  • [x] on-chain governance
    • [ ] CosmWasm smart contracts governance proposal pending
• [ ] IBC bridge to Agoric composable smart contracts planned
• [x] state-of-the-art multi-chain (IBC) wallet: Keplr
• [x] Connections to assets on several existing chains providing access to $billions in liquidity and actual progress coordinating climate action:
  • [x] Regen - Wilmot and Woodburn ... The credits have already been sold to Microsoft to help meet their climate goals -- Regen For Land Stewards
  • [x] Cosmos (ATOM): $6B
  • [x] Terra (LUNA): $24B, TerraUSD (UST): $9B
  • [x] Crypto.com Coin (CRO): $13B
  • [x] Secret/SCRT, Juno/JUNO, Akash/AKT, Sentinel/DVPN, etc.
• [ ] ETH bridge emerging
  • [x] DEC 15, 2021: Gravity Bridge brings Ethereum to the multichain: Gravity Bridge enables the transfer of ERC-20 tokens between the Ethereum (ETH) and Cosmos blockchains.
  • [x] Gravity Bridge explorer shows 98 validators at time of writing
  • [ ] relayers operate IBC connection to Osmosis
  • [ ] Governance for adding ERC-20 token assets
  • [ ] scale UX from a dozen or so assets to hundreds
• [ ] Solana bridge
  • [ ] IBC work is in the brainstorming stage: [Design Proposal] Warp: A Bridge for Tendermint Chains - General - Solana Apr '20
• [ ] Avalanche bridge
  • [ ] IBC work is in the brainstorming stage: Cross-Chain Communication in Avalanche - General - Avalanche Forum Feb 2021
