Blockchain problems

  • Mechanism consensus: POW
  • Slow transactions: ~12s(mining time)
  • Low throughput: ~15 TPS(transaction per second)
  • High transaction fee: higher = faster

Scaling solution: sidechain

4 of 20

Plasma

  • A mechanism to:
    • Create a sidechain
    • Interact with the main chain

​

Sidechain

  • Own consensus mechanism: POW, POS, POA, ...

​

  • Independent secured solution.
  • Example: POW, 51% of power of the sidechain

​

Layer 2

  • Rely on security of the main chain.
  • Example: POW, 51% power of the main chain.
