[WG-OTTO] blockchain

Chainpoint is an attempt fixing a fundamental deficiency of blockchain, which is the cost and time to append a new block. This is owed to the proof of work principle, which is required for virtual currencies, but not for signed trust assertions. Merkle trees have better properties, and this seems to be the reason why they are used for certificate transparency.
