Notes

Self-describing characteristics for blockchain interchain integration and APIs.

Trust

  • Does it have finality

  • Key in ledger

Resilience

  • Bitcoin several billion in mining compute (highly resilient)

    • PoW 51% cost 

  • Altcoins little mining compute (little resilience)

Automated self-describing requirements (not characteristics of one offs)

  • Translation not census co-ordinator

    • How do you identify 

      • Fabric expose identity to API (or reach into for key)

    • How do you query state of ledger

      • Sawtooth meta categories

Use case

  • Switch ownership 

    • not switch chains (still not trivial) 

  • Lever both chains to do swap (smart contracts on both)

    • Degree of trust characteristics

  • Harder swap bitcoin/lightcoin

    • Are chains strong enough (no > 3rd chain)

    • centralize / decentralize

  • IRL 

    • Online house sale (overpriced)

    • Side agreement to sweeten the deal > integrate an additional smart contract on an additional blockchain (degree of trust)

APIs

  • IRL

    • Solidity on-contract hashmap > key get hash > salting > key + offset > need to know source code (query does not cost gas)

    • Hyperledger projects read source code or read API...(consider funelling requirements back to projects)
