The Lightning Network

  • A scaling solution for Bitcoin
  • Built on top of layer 1
  • The money being sent is also BTC

LN characteristics

  • Synchronous payments
  • Fees based on payment amount rather than transaction size in bytes
  • As with Layer 1, transactions are fully settled

Technical perspective

  • Separate network alongside Layer 1 network
  • Lightning anchors into Layer 1
  • Payment synchronicity requires availability of payment receiver
  • Interoperability between Layer 1 and 2 is challenging (UX)
