We trust schools and babysitters to look after our children. We trust banks to hold our money and to transfer it safely for us. We trust insurance companies to pay us should we meet with some disaster. When we make a large purchase – such as a house – we trust our solicitors or an escrow company to hold the funds until the transaction is complete. We trust regulators and governments to make sure these institutions are doing what they are supposed to be doing.
A good way to wrap our minds around ‘blockchain’ concept is to think of its most famous application: Bitcoin. And the best way to think about Bitcoin is not in terms of coins at all but rather as a giant ledger.
Bitcoin is just one version of the blockchain. The fundamental technology has the potential to replace a much wider range of human institutions in which we use trust to reach a consensus about a state of affairs. It could provide a definitive record for property transfers, from diamonds to Porsches to original Picassos. It could be used to record contracts, to certify the authenticity of valuable goods, or to securely store your health records (and keep track of anyone who’s ever accessed them).
But there’s a catch: what about the faithful ‘execution’ of a contract? Doesn’t that require trust as well?
