Look no further than digital crypto-based currencies for instantaneous, borderless and private spending of money and assets. Due to their underlying distributed ledger technology, every transaction is recorded, then verified through a technique known as mining. Many altcoins offer different algorithms, such as Proof-of-Stake (PoS) where ownership replaces mining, or you can build software applications (known as tokens or smart contract dApps) on platforms such as ethereum, EOS or Ripple, to name a few.
