Assignments

For each subject: study the material and try out the examples to get experience with is. Install all the mentioned software and experiment. Also look around on internet and on the other supplied source the get more information.

The idea is that we start with a simple smart contract that we are building out during the classes. So put some thought in your first smart contract. This could be:

Provide prove of what you have done by putting the source code and/or a screen shot on github: web3assignments

PD-11 IPFS   Create website to store & retrieve images on IPFS => capture source
    Store the website itself on IPFS => capture cid
PD-12 Security   Adapt your smart contract with access control => capture source
PD-13 Tests   Add (at least 5) unit tests to your smart contract => capture source and test results
PD-14 ENS   register ENS name (on testnetwork), connect it to your smart contract, use it in your website to address the contract => capture source
    register ENS name (on testnetwork), connect it to your IPFS site => capture screen of ENS application (https://app.ens.domains/) {on mainnet you can directly use this with metamask}
PD-15 New developments
