Interactions between any two or more entities require trust–the ability to rely and act on the commitments of others. Trust can be expensive and volatile, and the “cost of trust” in our society cannot be overstated. However, with modern technology trust no longer has to be provided by individuals or institutions. Instead, trust can be provided by and guaranteed in code. Leveraging public/private key pair cryptography and novel incentivization and punishment schemes, new protocols enable individuals and other entities to trust the reliability of records without relying on third-party overseers. The human factor, prone to unclear expectations and only enforceable through costly and convoluted legal agreements or even just veneers of decency, is removed. Operations are more efficient, reliable, predictable and less costly for all parties.
