* CORDA-1208: Notary service should persist the notarisation request signature along with the committed input states. This required modifying the uniqueness provider interface to accept the signature in addition to input states. Until now the committed state log used to be stored as a map of (state reference -> (tranasction id, consuming party)). Adding the serialized signature would mean inflating each state entry by around 700 bytes, which would be grossly inefficient. Instead, two tables are now used: one for storing (state referece -> transaction id) map, and another for storing the notarisation request details (transaction id, consuming party, date, signature). * Update api - all of these changes are only related to custom notaries
Sample applications
Please refer to README.md in the individual project folders. There are the following demos:
- attachment-demo A simple demonstration of sending a transaction with an attachment from one node to another, and then accessing the attachment on the remote node.
- irs-demo A demo showing two nodes agreeing to an interest rate swap and doing fixings using an oracle.
- trader-demo A simple driver for exercising the two party trading flow. In this scenario, a buyer wants to purchase some commercial paper by swapping his cash for commercial paper. The seller learns that the buyer exists, and sends them a message to kick off the trade. The seller, having obtained his CP, then quits and the buyer goes back to waiting. The buyer will sell as much CP as he can! We recommend starting with this demo.
- Network-visualiser A tool that uses a simulation to visualise the interaction and messages between nodes on the Corda network. Currently only works for the IRS demo.
- simm-valuation-demo A demo showing two nodes reaching agreement on the valuation of a derivatives portfolio.
- notary-demo A simple demonstration of a node getting multiple transactions notarised by a single or distributed (Raft or BFT SMaRt) notary.
- bank-of-corda-demo A demo showing a node acting as an issuer of fungible assets (initially Cash)
