* CORDA-986 and CORDA-985 CompositeKey and Signature verification performance fixes (#2467) * CORDA-696: Create separate transaction types for contract upgrade transactions. Add rationale around upgrade transactions Move contract upgrade transaction resolution logic into internal until it's stabilised. Throw a better exception when contract attachment not found Default legacy contract constraint to always accepting - needs to be changed to whitelist constraint before merging Introduce a new upgraded contract interface that allows specifying the legacy constraint. Remove StateLoader, make all tx resolution functions take in ServicesForResolution Contract upgrade transactions can handle whitelist by zone constraints When creating a contract upgrade transaction, make sure the attachment of the old cordapp gets attached when using hash constraints. Attachment lookup for a given contract class name only scans currently loaded cordapps, and we don't load old versions of cordapps. |

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)
