Notes

2025.02.06

總費時: 約80分鐘

前置至Week0,主要在講EPS(Ethereum Protocol Study)在做什麼即使命,可提交一個表單 (https://docs.google.com/forms/d/e/1FAIpQLSdLASV5RqAQv6I2KzA6DcxkFHKcZw3YuL3S3uXfsWUiYRsKRg/viewform)告知EPS你想學的知識點。 EPS計畫會講比較深、不會教你Solidity語言或開發DApp,而是去介紹整個以太坊的架構。 加入EPS成員還不能成為Ethereum Fellow,但鼓勵當成目標。

Week1

  • 行前讀:

  • 不可被destoyed and can't be shut down、公私鑰、隱私

  • 論文Ethereum Berlin Ver: 2022-04-17

  • EIPs: EIP1是範例。

  • executions-specsconsensus-specs(github.com/executions-specs)(github.com/executions-apis) (github.com/consensus-specs)(github.com/consensus-apis)

  • eth2book

  • Ethereum歷史

  • 設計原則:公共利益、中立、自由、敏捷、無風險等

  • EVM、State(data)、TXs(mempool)、p2p、JSON-RPC API、User/web3、Engine API、COnsensus Layer、Beacon API、validators的溝通 image image

  • Implementatios - EL

    • geth/go
    • reth/rust
    • ethereumjs/TS
    • ...
  • Implementatios - CL

    • ...
  • Testing

  • Other tests

    • Benchmarking, Stress
    • Shadow forks - live transition
    • Client tests, unit testing
    • CI/CD
  • 流程: Idea->Reserch->Specs->Implementation->Testing->Adoption/Rejection

  • Coordination

    • Dev calls (EL, CL, 4844, testnets, EOF...)
    • EIPs - Eth Maicians, EIPIP, Cat herders, R&D Discord, Ethresear.ch
  • Scalability Trilemma不可能三角 - Scalable, Secure, Decentralized

  • EPF cohorts history

2025.02.07

總費時: 約40分鐘

Week2

  • Matt講解程式碼,今天僅看了Block ValidationBlock Building
    • Block Validation: * err檢查 * for _, tx in range block.Transactions(){ res,err := vm.Run(block.Header(), tx, state) // 如果 transaction invalid那麼block也invalid } state = res * return state, nil
    • Block Building: * gasUsed+=gas; * return (env,txs,state)
  • 明天接著看Week2

2025.02.08

總費時: 約10分鐘

2025.02.09

總費時: 約10分鐘

Week2

  • 承前一日繼續觀看影片
  • execution layer會跟consensus layer互動
  • EVM的組成(PC, stack,memory,gas memory,code,block context/tx context, state)

2025.02.10

總費時: 約20分鐘

Week3

  • 今天講Consensus Layer
  • 區塊鏈為什麼好? 因為有digital scarcity
  • 那digital scarcity是什麼? scarcity是a user can't spend more coins than they have
  • 那怎麼做到digital scarcity? Don't have a single trusted operator
  • 如何remove a single trusted operator? 1. make digital system without a single leader 2. computattion is distributed across many nodes 3. Consensus 又稱state machine replication 4. 愈多節點(nodes),就愈難被攻擊
  • Byzantine fault tolerance -> 與consensus protocols有一段歷史
  • Satoshi solves Byzantine General's Problem
  • POW and heaviest chain algorithm mean any node 最終會converge to same current state as any other

2025.02.11

總費時: 約30分鐘

Week3

  • 承續前一日,week3影片,但我不太懂,想說之後回頭再看一遍。

Week4

  • 講安全及測試
  • EVM testing: EEST(Ethereum/Execution Spec Test)
    • test Filling: 皆為json files
    • Pre-State 停在此
    • Environment
    • Transaction(s)
    • Post-State

以下為明天:

  • 共識層的測試: ethereum/consensus-specs
  • Cross-Layer(Interop) Testing: Hive, Devnet, Shadow-Forks, Testnets
  • 安全: 淺在的issues, bugs
