More on blockchain and the cryptocurrency – Ethereum
Well to quote Blockgeeks:
Every single operation that takes part in Ethereum, be it a simple transaction, or a smart contract, or even an ICO takes some amount of gas. Gas is what is used to calculate the amount of fees that need to be paid to the network in order to execute an operation.
And gas is paid in ether. So while BTC’s value is purely a community backed medium of exchange/store of value ( i.e. a classic currency), the value of ether is more akin to barrels of oil, bushels of wheat or donkey-sacks of cocaine. And while some people or institutions might accept that as a payment method, that doesn’t make it a currency – its a classic commodity.

Two places I would suggest you look at are the Consensys Academy, for training on Ethereum, and the Hyperledger foundation.
Many other places (General Academy, Flatiron School, Coursera, etc.) also offer blockchain programs.
