Learn Solidity programming by hands-on examples

Ethereum is a second generation public blockchain. Second generation blockchains manage more than cryptocurrency assets, so they can manage any asset. The Ethereum nodes can run programming code called smart contracts. The term smart contract sounds like they are a legal term, but, in reality, smart contracts are no different from any computer program. Smart contracts take action on Ethereum transactions. Ethereum is a single ledger blockchain, and it uses a cryptocurrency called Ether.

Solidity is a scripting language used mainly for blockchain smart contract writing. Solidity runs on the Ethereum blockchain. Solidity is object oriented. It resembles Java in its structure. A programmer can use Solidity to model real life object attributes related to the items involved in the transactions. Solidity also supports functions to execute the actions for the items involved in the transaction. 

In this course you learn how to program in Solidity to develop and deploy Ethereum blockchain applications.
