From premise to practice of social consensus: How to agree on common knowledge in blockchain-enabled supply chains

Attaining “Common Knowledge” is essential in the formation of deals and agreements, but hard to achieve over point-to-point communication networks such as Internet. While blockchain technologies provide a helpful mechanism form technical consensus, originally created resolve double-spending problem, little does it address impediments proper contract that have do with quality exogenous data, asymmetry information, or even its suitability (the colloquial garbage-in/garbage-out problem). In face limitations we explore how strengths consensus can be utilized by introducing another dimension – what called social which directly addresses true (if retrospective) Common Knowledge arms-length agreement between multiple actors. We eschewed notion an epistemological concern, instead focus on mechanisms environments actors sustain bodies information enable them go about their activities reasonable level confidence others supply chain will ‘do bit,’ backed ‘failsafe’ enforced cryptography holds unharmed case envisioned finality not obtained. These create essentially retrospective common knowledge, lesser variant, mutual knowledge. propose implementation from preferred multisig primitive, builds improves Gnosis multisig, use decentralized blockchain-powered chains consisting parties, human machine.
