Paradigm partners release PACTs proposal, allowing holders from the Satoshi era to prove control without moving BTC

Concerns about quantum computing in Bitcoin always revolve around a "Satoshi-related problem." If a sufficiently powerful quantum computer emerges, millions of Bitcoins stored in old wallets with exposed public keys may face the risk of being stolen, including approximately 1.1 million Bitcoins that are allegedly owned by the anonymous creator Satoshi, currently valued at about $84 billion.Senior developer Jameson Lopp and five other developers formally proposed this plan through BIP-361 in mid-April, which aims to gradually phase out addresses vulnerable to quantum attacks over a five-year timeline and freeze any coins that fail to complete the migration. However, this proposal creates another issue: Satoshi and all other long-dormant holders would have to publicly "reveal themselves," or risk losing access to their assets.Dan Robinson, a general partner at Paradigm, released a proposal on Friday that suggests a way to circumvent this trade-off, with the core concept being "Provable Address Control Time Stamps" (PACTs). The main idea of PACTs is not to move coins, but to timestamp ownership proofs on specific dates, without disclosing any information externally until the wallet owner truly needs to spend.If Bitcoin later implements a soft fork to freeze coins vulnerable to quantum attacks, the protocol could include a rescue path that accepts STARK proofs (a type of zero-knowledge proof that remains secure against quantum computers), proving that the holder created their commitment before the existence of quantum hardware. When the holder wishes to spend, they submit this proof, and the network releases the corresponding coins. This redemption process will not reveal any information about the address, amount, or even the original timestamp creation time.

Curve has launched a bad debt recovery mechanism, allowing impaired claims to exit through trading or participate in recovery

Curve Finance officially announced that it is introducing a bad debt recovery mechanism based on on-chain market mechanisms, allowing CRV-affected users in certain lending markets with bad debts to choose different recovery strategies: directly selling their claims to exit, continuing to hold and wait for potential recovery, or providing liquidity to earn fees and incentives. The core of this mechanism is to establish a trading pool between crvUSD and the tokens of the affected claims, allowing bad debt claims to be priced in the market and creating liquidity, thereby providing users with an immediate exit channel instead of relying solely on the final liquidation results.It is reported that after the cryptocurrency market crash in October last year, some lending markets under Curve Finance experienced bad debt issues, with various liquidity pools being impacted by severe price fluctuations and liquidity contraction, leading to some deposit users facing withdrawal restrictions and asset losses.Curve stated that the recovery mechanism will not eliminate losses or guarantee recovery, but will gradually reflect risks and recovery expectations through a market-oriented approach. Additionally, if the governance layer distributes rewards through the veCRV incentive mechanism, it will help enhance liquidity depth, improve exit conditions, and strengthen market pricing efficiency.

Bitcoin failed to break through the resistance level of $80,000, with on-chain indicators showing a mix of bullish momentum and cautious sentiment

Bitcoin fell below $76,000 after failing to break through $80,000, with uncertainties surrounding the reopening of the Strait of Hormuz and the macroeconomic situation unsettling the market.Meanwhile, technical indicators and on-chain data provide mixed signals regarding whether BTC can sustain this round of rebound. Bitcoin recorded a 30% recovery after hitting a low below $60,000 on February 6, but it stalled under selling pressure in the supply zone between $78,000 and $80,000. This range also coincides with the current 20-week exponential moving average (EMA), reinforcing the significance of this resistance level.Michael van de Poppe, founder of MN Capital, stated that the current pullback is "typical behavior" ahead of the FOMC meeting. He added, "I believe we are still in a phase of strong market conditions." On the support side, Bitcoin has tested the support level at $75,500, which also serves as the lower boundary of the 20-day EMA, 100-day EMA, and an upward channel.Glassnode's UTXO Realized Price Distribution (URPD) data shows that direct resistance is around $78,000, where investors hold 335,650 BTC; the average purchase price of about 298,560 BTC is $75,500, forming a key support level.On the on-chain front, Glassnode data indicates that the Bitcoin market exhibits "a coexistence of bullish momentum and cautious sentiment." The spot CVD (Cumulative Volume Delta) rose from $18.3 million to $54.8 million, with an increase of nearly 200% over the past week, reflecting strong bullish sentiment among market participants. However, spot trading volume decreased by 13.8% from $6.95 billion a week ago to $5.99 billion, "indicating a reduction in market activity." During the same period, the number of daily active addresses fell by 1.6%, showing a more subdued network participation.
