Blockchain is a New OS?

Hey, we have a brand-new scheduling algorithm. Let’s create a new operating system!

Hey, we have a brand-new consensus algorithm. Let’s create a new blockchain network!

Current Status

  • Everybody uses Ethereum to issue tokens
  • Nobody builds applications on Ethereum
    • High transaction cost
    • Low performance (10-20 TPS)
    • Slow block confirmation time

​

Solution

  • Issue tokens first and wait until Ethereum solves the blockchain scalability problem
    • PoS (Casper)
    • Raiden
    • Sharding
    • …
  • Claim you can solve the problem by yourself by forking Ethereum/EOS or creating a new blockchain platform from scratch

CodeChain: Consensus Laboratory

Hybrid schemes were developed that combine PoW chains with BFT to

  • increase throughput
  • decrease latency to finality
  • promote fairness

​

Use a permissionless chain to determine a participant/proposer rotation

  • Byzcoin, Bitcoin-NG and Hybrid Consensus

A chainless BFT protocol in the permissionless settings that uses PoW to generate propositions and rotate members

  • Solida/Solidus

Uses a permissionless chain for recovery from failures

  • Thunderella

Uses a BFT engine as a finalizing authority over a permissionless chain

  • Casper the Friendly Finality Gadget
