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)
