やっとテンプレかできた！ニュースはちぇっくしていこう丁寧に分類していく

Eigo-Mt-Fuji commented 2 years ago

これは理解したい https://twitter.com/Sota_Web3/status/1526185128678289408?t=80v3chR7Cn8TdFhrycJkSw&s=19

LN=Lightning Networkとは?

BTCのオンチェーン取引のスケーラビリティ問題(秒間7件しか処理できない)解決のために考案された、遅延なく個人間取引を完結できるようにする仕組み(=LN)。LNの実体は取引実行のソフトウェアらしい。つまり、対象のブロックチェーン上で、取引をする個人間のP2Pネットワーク接続、取引のためのチャネルオープン～トランザクション実行・クローズまでの一連の取引を管理するソフトウェアを意味する。

Web3 型人材マッチング『Braintrust』
- 従来の人材マッチングとWeb3 型人材マッチング『Braintrust』の違い
- 不透明で中間搾取が行われる人材マッチング
- 手数料も透明化され参加者同士で決めていくDAO的組織
  - NASA、NIKEと大手企業も利用。
  - 自社ガバナンストークンで運営方針を決めれたり、学習や紹介を通じて稼ぐことも可能
- 自社ガバナンストークン BTRST
- 多数の取引所で上場済。100カ国、5万人のメンバーで利用されている。
- Youtube、blog、TwitterなどSNSの発信も積極的。
- 仕事を探しながら稼ぐ、Job hunting to earnも可能。
  - 全てがDAO化するのは時間の問題か

Rearchitecting apps for scale https://blog.coinbase.com/rearchitecting-apps-for-scale-db438d058e79
- Coinbase Chose Relay as our GraphQL client library
- Relay is
  - unique among GraphQL client libraries
  - how it allows an application to scale to more contributors while remaining malleable and performant.
  - Relay’s pattern of using fragments to colocate data dependencies within the components that render the data
- Migrating our applications to GraphQL and Relay is just the beginning.
  - We have a lot more work to do to continue to flesh out GraphQL at Coinbase.
- Here are a few things on the roadmap
  - Incremental delivery
  - Coinbase’s GraphQL API depends on many upstream services
    - GraphQL won’t send its response until all of the data is ready, meaning a query will be as slow as the slowest upstream service
  - Live queries
  - With GraphQL, plan to explore the use of Live Queries (more on this in a blog post down the road)
  - Coinbase applications tend to have a lot of rapidly changing data, crypto prices and balances
  - now use Subscriptions for delivering live updates(Subscriptions are not an ideal tool for our needs)
  - Traditionally, we’ve used things like Pusher or other proprietary solutions to keep data up-to-date.
  - Edge caching
  - we’d like to build and deploy a global, secure, reliable, and consistent edge caching layer to decrease total roundtrip time for all queries.
    - Coinbase is dedicated to increasing global economic freedom.
    - To this end, we are working to make our products performant no matter where you live,
    - including areas with slow data connections.
  - Collaboration with Relay
  - The Relay team has done a wonderful job and we’re incredibly grateful for the extra work they’ve done to let the world take advantage of their learnings at Meta.
- problem that GraphQL solves
- it allows related data to be nested in the request moving this waterfall to the backend server that can combine these requests with much lower latency
- When Coinbase supported 5 assets the application was able to make a couple of requests one to get the assets (5) and another to get the wallet addresses (up to 10) for those assets and stitch them together on the client.
- However this model doesn’t work well when a dataset gets large enough to need pagination.
- Either you have an unacceptably large page size (which reduces your API performance)
- or you are left with cumbersome APIs and waterfalling requests.
- If you’re not familiar
  - a waterfall in this context happens
  - when
    - the client has to first ask for a page of assets (give me the first 10 supported assets),
  - and then
    - the client has to ask for the wallets for those assets
    - give me wallets for ‘BTC’, ‘ETH’, ‘LTC’, ‘DOGE’, ‘SOL’, …).
  - Because the second request is dependent on the first, it creates a request waterfall
    - When these dependent requests are made from the client
    - their combined latency can lead to terrible performance.
