blockchain is a collection ofrecords (called blocks), where each block links to the previous block using cryptography. Eachblock contains cryptographic hash, timestamp and data relevant to its application. Think ofit as a distributed ledger where instead of information being stored in a database it is storedon the blockchain. Some examples of solutions that use a blockchain at its core are:1. Cryptocurrencies (however, for this project you may NOT do a cryptocurrency)2. Smart contracts3. Trading4. Supply chain management5. Anti-counterfeiting6. Healthcare7. Domain names8. Proof of existence9. Voting10. and many others! Programming Language: Java The use of third-party libraries for primary functionally is strictly prohibited, however, third party libraries can be used for other functionality such as communications and visualisation (such as normal JavaFX, JFreeChart, GraphStream, JGraphT, Yworks, JUNG or JMonkey).
