The Roadmap

[ghost]

Yet another roadmap...

Moving from MetaMask/eth-ipfs-browser-client#1

Ethereum Browser Light Client Roadmap (MVP)

Divided in five big areas

• Obtaining Data from devp2p
• Kitsunet: metamask peer network
• Bridge Peers: Make eth contain available to libp2p
• Browser Peers Why we are here
• Metamask Extension Ops

OBTAINING DATA FROM devp2p

• Devp2p Node Scrapper
• Block Header Sync
• Client Fork (to add trie nodes to RedisDB)
• Snapshot download (from devp2p)

KITSUNET (Metamask peer network)

• Add mustekala box mk1 docker to repo
  • Deploy
• Signalling servers
  • Docker package
  • Deploy
  • Network bootstrapping
• PubSub Testing for blockchain head update
  • May include signature of messages / "network of trust" ?
• Messaging testing
  • Request an "index"
• Metrics
  • Collection

BRIDGE (Make eth content available to libp2p)

(go-ipfs)

• Mount RedisDB Datastore problem
• Bootstrap into kitsunetto
• Custom Content Routing System
  • Sharding criteria, metadata indexes, "delta computations", etc
• Publish new blockchain head
• Respond to requests
  • eth - ipld dag requests
  • CRS indexes requests

PEERS

(js-ipfs)

• Bootstrap into kitsunetto
• Subscribe to new blockchain head
• Custom Content Routing System
  • Maintaining Ethereum Trie Shards
    • Deterministic and/or discrete
    • Incentive system
    • Updating them on triggers, request indexes, compute deltas, request parts.
• Manage other peers requests
  • eth - ipld dag requests
  • CRS indexes requests

Metamask Extension Ops

• eth_blockNumber
• eth_getBalance
• ... more to come. (See breakdown in comment below)
