From “What is Blockchain?” to building a blockchain in less than an hour

Verifiable Data and ContractsA Blockchain can create a verifiable record of any data, file, or contract.

If you are interested in learning how to implement a blockchain contract, I’ve put together an easy-to-follow, step-by-step tutorial below.

There are two types of accounts: Externally Owned Accounts, which are controlled by human users, and Contract Accounts, which are controlled by their internal contract code and can be activated by an Externally Owned Account.

A “Smart Contract” or “Decentralized Application” is determined by code in a Contract Account which will be activated when an EOA sends a transaction to the Contract Account.

The first, a mortal contract, specifies a contract that can be killed by the person who wrote it and it needs to be declared as such, as contracts are immortal by default.

Preparing your Contract for DeploymentNow that you have your mortal contract and your greeter contract, you will need to define the greeting and instantiate your account objects.

Ethereum Block Chain Explorer allows you to view current pending contracts as well as great Ethereum statistics.
