  1. an ASA for each aAsset (like aBTC, aETH, ...)
  2. one verifier for all aAssets, IDEALLY. The limit of TEAL would be annoying here.
    1. We can do one contract C1 to submit ZKP verified price, one contractC2 to distribute the price.
    2. The C2 only accepts price from C1, and the price is verified by ZKP. C2 stores all the info and users will ask price from C2.
    3. In this way, the two contracts are shorter and stores less prices hence shorter.
  3. Trade and other contracts will read price from C2 in before or the only contract in (2.). (From [https://github.com/Artcoin-Network/artificial-algorand-contract/pull/8#issuecomment-1055551621])
  • How to review design docs(From ZMY)
  • Don't fix too much on details.
  • Use too much time on details.
  • When to raise issue: in most of the time we don't need to raise issue. Q&A. A full docs would be with Q&A.
  • Slides: too many questions and ambiguity. Docs can avoid these problems.
  • Docs are designed to be read to the end, maybe the "why"s are explained in the latter part.
  • Write the problem clearly, including the origin.
  • Try first then raise issue, and try to solve it.
  • Productivity > Attitude > Synchronicity
  • Confluence Inline comment has no delay publish functionality. So raise the question on the second/third reading.

Testing VSCE:

  • mushan.vscode-paste-image
  • d3v.pastespecial

More to test:

  • rockingskier.copy-copy-paste

Add to note:

  • jakob101.RelativePath
  • christian-kohler.path-intellisense

Want: VSCE: .md auto refactor when RelativePath changes. Why Obsidian made a new platform (doesn't justify closedness): 1.money; 2. too many extensions with VSCE; 3. New Hotkeys/UI.

  • Discarded Teambition, for these defections: #TODO: add to TOOL
    • Link without href tag (with onClick event)
    • Tasks in TODO cannot convert to issue/story
    • Gantt chart is not so clear
    • Chinese server and international server don't share the same data
    • Cannot change default issue priority level
    • Last straw: Untraced bug when failing to add list(task group) and issue (sometimes duplicated and sometimes none).
  • Clean working desk. All three monitors work perfectly now. But currently no mic/webcam. Easiest solution is to use an external one.

  • ZKP#idea: In an (interactive) ZKP system, the prover can fool the verifier plagiarizing the same answer from a real ZKP prover. Like I request a 3-color map from M$, and M$ doesn't have the answer, but he asks google with same question and google's prover was real. Idea from reading Origin3

  • ZKP, simulator: Verifier's move cannot be predictable, this includes that time is not reversible.
  • ZKP#idea with probabilistic model: Prover: I will score 60% of total points.
  • ZKP is based on cryptographic algorithm: [https://en.wikipedia.org/wiki/Commitment_scheme] We can change the key so that the "authenticator" sees different result when opening the box with different keys? Just like the "time machine experiment" in [https://blog.cryptographyengineering.com/2014/11/27/zero-knowledge-proofs-illustrated-primer/] The cost is to break the hash-key system, so maybe its practically safe.
  • ZKP#idea: Any NP-complete problem can be designed into a cryptographic algorithm.
  • ZKP#idea: We can also use ZKP to verify messages like password without passing it. (e.g. require&compare Hash(msg+'a'), Hash(msg+'b'), Hash(msg+'c'), although practically this is worse than just using an asymmetric cryptography.)
  • UX: If a setting needs to confirm/save. Use a floating button or put the button at the beginning.

  • Crypto Currency: mint:

    Minting is the process of validating information, creating a new block, and recording that information into the blockchain. Thus, Proof-of-Stake is the minting process for how blocks are created and how data is added to a block. Origin Creating new crypto coins using a proof-of-stake (PoS) consensus algorithm. In contrast, proof-of-work (PoW) cryptos come into existence by being "mined." The mining and minting terms were created from real-world coin making. Gold and silver are "mined" out of the ground and then "minted" into coins for circulation. Origin
