When we say the words “block” and “chain” in the context of blockchain, we are actually talking about digital information (the “block”) that is stored in a public database (the “chain”). The Bitcoin protocol is built on the blockchain. So, with the launch of Bitcoin in 2009 as the first cryptocurrency, blockchain technology had its first real-world application.

  • ASIC Bitcoin miners are electronic circuits designed for the sole purpose of mining bitcoins.
  • In cryptocurrency, mining is the process of managing the blockchain. 
    • The first miner to find the solution to the puzzle is able to authorize the transaction (to add bitcoin to the block). Each winner in the Bitcoin-mining lottery receives a reward (a certain amount of bitcoin). The reward includes all of the transaction fees for the transactions in that block, which motivates miners to collect as many transactions into a block as possible to increase their reward.

      An application-specific integrated circuit (ASIC) miner is a device that is designed for the sole purpose of mining—not coal, but rather digital currency. Generally, each ASIC miner is constructed to mine a specific digital currency. So, a Bitcoin ASIC miner can mine only bitcoin. Think of Bitcoin ASICs as specialized Bitcoin mining computers, or “bitcoin generators.”https://12ea7800963ffec019cbea4bac9dd936.safeframe.googlesyndication.com/safeframe/1-0-37/html/container.html
