Payment chain

Every step of a payment made through Donut API is written here as a block. A block carries the hash of the block before it, so an old step cannot be changed without breaking every block after it.

The blocks hold no name, no amount and no transaction id. Someone who has a transaction id sees its detail on the page of that transaction, where each hash is recomputed from the block data and compared with this list. The chain is kept by Donut API on its own server. It is a record that anyone can check, not a network of computers. Source: /v1/chain, described in the docs.
