Ledger CTO: Post-Quantum Crypto Migration Enters Pivotal Phase, Blockchain Leans Towards Hash-Based Signature Scheme
April 23 — Ledger CTO Charles Guillemet noted in a blog post that post-quantum cryptography (PQC) is entering a critical phase. While the timeline for quantum computers capable of breaking current cryptographic systems remains uncertain, the industry widely agrees a shift to PQC is inevitable.
The traditional sector has a clear roadmap, led by the U.S. National Institute of Standards and Technology (NIST): phasing out vulnerable legacy algorithms by 2030, with full disablement by 2035. Large enterprises and government agencies are accelerating preparations to complete the transition by 2029.
On the technical front, encryption and key exchange will transition to ML-KEM (formerly CRYSTALS-Kyber) to counter “decrypt-then-collect” quantum attacks. But in the blockchain ecosystem, the core focus is digital signatures. Current mainstream PQC signature schemes fall into two categories: lattice-based ML-DSA (formerly CRYSTALS-Dilithium) and hash-based SLH-DSA (formerly SPHINCS+).

Pyth announces infrastructure upgrade, with economic model shifting to a revenue-driven approach
On April 23, Pyth Network unveiled infrastructure upgrades and a shift to a revenue-focused economic model. Per Proposal OP-PIP-100, Pythnet will sunset gradually by 2026, with the network pivoting to next-gen infrastructure “Lazer”—and Pyth Pro and the Data Marketplace set to be its core future products.
At the same time, the OIS reward mechanism will be phased out via OP-PIP-103 (with parameter Y set to 0), ending reward distributions. Staking and penalty mechanisms, however, will remain in place. Roughly 1 billion PYTH tokens were staked across ~120 data provider pools during OIS’s run, with no forfeiture proposals filed in that period.
In its new model, Pyth is moving from token-reward-driven to revenue-driven operations. The PYTH Reserve has amassed ~12 million PYTH tokens via open-market buybacks funded by protocol revenue. Revenue streams include Pyth Pro, core oracle services, and the Data Marketplace. With integrations with Polymarket, Kalshi, and multiple trading platfo

「BTC OG Insider Whale」 Agent: The Evergrande Crisis is Severely Underestimated by the Market, Currently Without a Solution
**April 23 Update**
Garrett Jin—agent with "BTC OG Insider Whale"—posted today noting:
- Brent crude trades at $103; S&P 500 hits an all-time high.
- March data from Goldman Sachs’ prime brokerage shows a global short-to-long ratio of 7.6:1 (fastest net global sell-off in 13 years).
- Post-ceasefire news, Goldman’s "highest-short" 50-stock basket surged 7.1% in one day—**short-covering, not belief-driven buying**.
Trend-following funds (CTAs) are pouring record capital into U.S. equities:
- The "Big Seven" has rebounded 20% from its March 30 low.
- Nasdaq posted its longest winning streak since 1992.
**But the rebound’s supporting assumptions are unfulfilled**:
- Hormuz Strait reopening, lower oil prices, easing inflation, Fed rate cuts—none have materialized.
Recent "48-hour drama" proves this:
- April 17: Iran declared the Strait "fully open" → Brent plunged 9% to ~$90.
- <24hrs later: Iran’s Revolutionary Guard Corps fired on an oil tanker, warning "any sh

19-year-old Female College Student from Guangdong Sold to Telefraud Compound in Myanmar, Family Pays 30,000 USDT Ransom but She Remains in Captivity
**Headline: Chinese Freshman Abducted in Thailand, Sold to Myanmar Fraud Center; Release Negotiations Ongoing**
A 19-year-old Chinese college freshman was abducted in Thailand earlier this month, trafficked to a telecom fraud compound on the Myanmar border, and remains in captivity amid ransom talks, her family and authorities confirmed Tuesday (April 23).
The student, identified only by her pseudonym Xiaoyang, is a freshman at a university in Guangdong province. She traveled to Thailand on April 10 at a friend’s invitation to celebrate the Songkran Festival. Upon landing in Bangkok, she was immediately detained and sold to a fraud center in Sop Moei Ta, a Thailand-Myanmar border area.
On April 13, her family was contacted by a man claiming to be a “kind-hearted brother.” He said he had paid 29,000 USDT (cryptocurrency) to buy Xiaoyang from traffickers and demanded a 30,000 USDT ransom (equivalent to over 200,000 Chinese yuan) for her release.
After the family transferred t

### Notes on American English adaptation:
1. **Date format**: Used `4/23` (month/day/year) instead of day-first;
2. **Time expression**: Swapped `18:00` for `6:00 PM` (more natural in U.S. casual/financial copy);
3. **Terminology**: Replaced `limit` with `cap` (common in U.S. crypto staking/finance for "maximum allowed");
4. **Concision**: Used `roll out`/`run from` instead of formal phrasing
