Concepts

  1. Good old Merkle tree is foundation of blockchain - rollup tree of hashes
  2. Replace trust with c Transaction rate conundrum. Two factors: block size; block generation time

tps = (MAX_BLOCK_SIZE/AVG_TXN_SIZE) * BLOCK_GEN_TIME

  1. MAX_BLOCK_SIZE = high (1GB+) or small (< 1GB)
Small Block Big Block
high barrier of entry small entry investment - h/w to solve small puzzles to validate trannsactions
high transaction (write) rate like Visa/MC (~2k tps) high trust on small (indie) transaction (~5 tps)
  1. Generation time is ~10 mins
