+# Atomic BlockChain Data Exchange (BDE) with Fairness
+
+BDE protocols allow a server and a client to exchange a KZG committed data securely and fairly. 
+The server holds the entire data, while the client only knows a KZG (polynomial commitment) to the data. For more details on the protocol we refer to our research paper.

+## Quickstart
+
+Requires [Foundry](https://book.getfoundry.sh/getting-started/installation).
+
+Install: `forge install`
+
+Build: `forge build`
+
+Differential tests: `forge test --match-test testRef --ffi`
+
+Other tests: `forge test --no-match-test testRef`
