From the Fed to the Chain #5｜What’s the Real Value of Blockchain? Every time you swipe a card, transfer money, or make a deposit, you’re quietly paying a hidden “trust tax.”A friend recently said: “Isn’t blockchain just a zero-sum game for speculators?” That got me thinking—why does blockchain matter?If I had to sum it up in one line: Blockchain provides cheaper trust. You might ask: “Wait, trust costs money?” Of course it does. When you make a bank transfer, do you worry your money might dis...

Japan’s era of ultra-low interest rates didn’t happen naturally — it was a greenhouse for arbitrage, carefully built by the Bank of Japan (BOJ). This decade-long yen carry trade was actually built on one institutional foundation: Yield Curve Control (YCC). Once that foundation starts to crack, the towering arbitrage structure on top begins to shake. So, what is YCC? Simply put:The BOJ sets a target interest rate (e.g., 10-year government bond yield at 0%) and commits to unlimited bond purchas...

🧭 主控權核心定義：主控權 = emotional control（情緒穩定）＋ situational lead（場面引導） 不是誰聲音最大，而是誰能定義節奏、邊界與結果。🧱 原則一：你可以設定規則，不必總是詢問意見主控權的第一步是「定義」，不是等待。不需要等大家都有共識，才開始推動事情。話術例句：「我先提一個方向，大家再補充看看？」「目前沒人反對，我們就照這個走囉。」🧱 原則二：模糊態度要被你來界定對方不說話、敷衍、不投入，就是一種信號。你可以定義沉默＝同意，也可以說明規則。話術例句：「我就當作沒問題囉，之後就照這個方向進行。」「你如果要調整，也要一起投入喔。」🧱 原則三：場面混亂時，用「整理＋定錨」來帶節奏不需要說服所有人，只要幫大家整理出邏輯與現狀。把混亂轉為可處理的選項，就是主導。話術例句：「我整理一下目前的方向⋯⋯」「如果我們不現在決定，就會一直卡著。」🧱 原則四：鼓勵參與，但設立責任門檻參與發言＝也要參與後續處理拒絕那種「只出一張嘴、不下水」的貢獻模式話術例句：「你可以提不同想法，但要一起討論處理。」「要調整沒問題，那就請你也幫忙協調。」🧱 原則五：主控...

With the Pectra upgrade completed yesterday, let’s revisit Ethereum’s scaling roadmap: The Surge. Amid this wave of scaling, a crucial technology is quietly reshaping the rules of the game — PeerDAS (Data Availability Sampling). Why do we need PeerDAS?Ethereum is evolving into a multi-chain ecosystem centered on rollups. The main chain’s role is to store and verify the data submitted by these rollups. But as data volume explodes, the traditional approach of downloading and verifying entire da...

For decades, U.S. government bonds have been considered the safest investment—almost a textbook answer to “where to park your money without taking risks.” In other words, lending money to the U.S. government was seen as a sure bet. But this confidence wasn’t based on gut feeling—it was backed by data:Since the 1990s, U.S. government debt has increased more than sevenfold, yet bond yields have actually declined. That signals market trust: even with growing debt, the U.S. can keep inflation und...

From the Fed to the Chain #6 | BLS Signatures: The Crypto Magic That Slims Down Ethereum TransactionsEvery Ethereum transaction carries a digital signature proving, “Yes, I made this transaction.” Right now, Ethereum uses ECDSA signatures—each one is separate, can’t be merged, takes up space, and has to be verified one by one. This makes L2 chains bloated and sluggish. What’s BLS Signature? BLS (Boneh–Lynn–Shacham) signatures are crypto magic for slimming down signatures. They let you aggrega...
