18. Proof of work
The Proof of Work is a brute force search for nonces so that the hash of the block header
meets a certain target difficulty.
By expending resources (hardware, electricity, cooling) miners race to solve the hashing
puzzle. The winner claims the bitcoin reward by announcing that they have performed the Proof
The cumulative Proof of Work in the blockchain is what secures the blockchain and makes it
tamper proof and immutable
Current mining activity https://blockchain.info/charts/hash-rate
The target difficulty adjusts approx. every two weeks to reflect the total hashing power and the
average time to mine the block to be 10 minutes

A decentralized network to run smart contracts
A more technical definition – Ethereum is a distributed
state machine (a global computer) with no single point
Compare this definition to the standard client/server

program instead of a central (trusted) server.
Ether is the currency to pay for your contract to be
