The COR matrix has been recorded on the bitcoin blockchain and now we have a banner message live as our first “hello world” smart contract on the ethereum blockchain. To interact with this smart contract go here:

MyEtherWallet Smart Contract Interaction Page

Paste in this Ethereum blockchain smart-contract address:

0x057590fB6Aa457E42ca2028A3815652eE7221049

Then paste in the ABI (Application Binary Interface, is basically how you interact with the bytecode at the address above and get data back):

[{“constant”:true,”inputs”:[],”name”:”display”,”outputs”:[{“name”:””,”type”:”string”}],”payable”:false,”stateMutability”:”view”,”type”:”function”},{“constant”:false,”inputs”:[],”name”:”kill”,”outputs”:[],”payable”:false,”stateMutability”:”nonpayable”,”type”:”function”},{“inputs”:[{“name”:”_banner”,”type”:”string”}],”payable”:false,”stateMutability”:”nonpayable”,”type”:”constructor”}]

Smart contract and ABI entered.

Then press the “Access” button. Now you are ready to interact with the smart contract:

Read/Write interaction pull-down.

Finally, select “display” from the read/write contract pull-down and read the output. You’ve just interacted with a live smart contract !

Output of the smart contract on display.
