Cardano price prediction 2026-2032: Will ADA recover to $1 soon?
Key takeaways : Cardano’s price is expected to surpass $1.33 in 2026. By 2029, ADAUSD could reach $4.72. By 2032, Cardano might reach a maximum price of $4.46. Cardano is a third-generation blockchain platform launched in 2017 by Ethereum co-founder Charles Hoskinson. Designed for decentralized applications and smart contracts, it uses Ouroboros—a unique, energy-efficient Proof-of-Stake consensus mechanism. Cardano’s two-layer architecture separates transactions from smart contracts, enhancing scalability and flexibility. Its native cryptocurrency, ADA, is used for transaction fees, staking, and governance, allowing holders to influence the platform’s future. Emphasizing a research-driven, peer-reviewed development approach, Cardano aims to address challenges in blockchain, such as scalability and sustainability, making it a strong alternative to platforms like Ethereum. Perhaps you’re wondering: with its innovative technology, can Cardano’s ADA reach new all-time highs soon? Let’s uncover what the future holds for Cardano. Overview Cryptocurrency Cardano Token ADA Price $0.2484 Market Cap $8.99B Trading Volume (24-hour) $278.19M Circulating Supply 44.99B ADA All-time High $3.10 on Sept 02, 2021 All-time Low $0.01735 on Oct 01, 2017 24-hour High $0.2507 24-hour Low $0.2472 Cardano price prediction: Technical analysis Metric Value Volatility (30-day Variation) 1.92% (Low) 50-day SMA $ 0.2543 14-Day RSI 48.84 (Neutral) Market Sentiment Bearish Fear & Greed Index 30 ( Fear) Green Days 14/30 (47%) 200-day SMA $ 0.3701 Cardano (ADA) price analysis ADA is trading flat around $0.25, stuck in a tight $0.24 to $0.26 range with no clear breakout direction. Weakness stems from fading sentiment, low institutional conviction, and growing community frustration over governance and treasury decisions. The Node 11.0 hard fork and potential spot ETF approval remain key catalysts that could push ADA above $0.26 toward $0.28. Cardano price analysis 1-day chart: ADA finds support at $0.24 as bulls eye a breakout above $0.27 ADA is trading at $0.2504, up 1.09% on the day, after a prolonged downtrend from highs near $0.44 in early 2026. Price has been compressing tightly in the $0.24 to $0.26 range since April, suggesting exhaustion of selling pressure and potential base formation. The series of smaller candles in recent weeks indicates decreasing volatility and a possible accumulation phase. ADAUSD 1-day price chart by TradingView The key horizontal support sits firmly around $0.24, which has held multiple times. For a bullish reversal to gain credibility, ADA needs a convincing daily close above $0.27. Failure to do so risks another leg down toward the $0.22 area. ADA price analysis 4-hour chart: ADA consolidates between $0.24 and $0.26 as Hard Fork Catalyst could spark next move ADA is trading at $0.2505, up 0.23%, showing signs of stabilization after a steep downtrend from $0.44 in early 2026. The 4-hour chart reveals price has been ranging tightly between $0.24 and $0.26 since April, with lower highs gradually flattening out, hinting that bearish momentum is fading. ADAUSD 4-hour price chart by TradingView The $0.24 level continues to act as solid support, having rejected multiple breakdown attempts. However, price remains capped below the $0.26 resistance zone, keeping the overall structure neutral to slightly bearish. A sustained push above $0.26 is needed to shift momentum bullish and open the path toward $0.28 and beyond. ADA technical indicators: Levels and action Daily simple moving average (SMA) Period Value Action SMA 3 $ 0.2471 BUY SMA 5 $0.2475 BUY SMA 10 $ 0.2492 BUY SMA 21 $0.2488 BUY SMA 50 $0.2543 SELL SMA 100 $0.2710 SELL SMA 200 $ 0.3701 SELL Daily exponential moving average (EMA) Period Value Action EMA 3 $0.2481 BUY EMA 5 $0.2482 BUY EMA 10 $0.2487 BUY EMA 21 $ 0.2496 BUY EMA 50 $0.2570 SELL EMA 100 $0.2894 SELL EMA 200 $.3721 SELL What to expect from the Cardano price analysis next? Based on the current 4-hour structure, ADA is at a critical decision point. The prolonged consolidation between $0.24 and $0.26 suggests the market is building energy for its next significant move. If buyers manage to break and hold above $0.26, the next resistance levels to watch are $0.28 followed by $0.30, which previously acted as a key support zone during the March selloff. However, if the $0.24 support gives way, a deeper correction toward $0.22 becomes likely. The upcoming Cardano Node 11.0 hard fork could serve as a fundamental catalyst to spark renewed buying interest and push price higher. Why is Cardano down today? ADA’s weakness today comes down to several converging factors. Cardano’s social dominance metric has been declining since early April, signaling fading market interest and weakening investor sentiment. The prevailing weakness is largely attributed to a lack of buyer follow-through, with retail participation present but institutional conviction missing to drive a meaningful trend reversal. Community frustration is also growing, with governance tensions, treasury spending scrutiny, and a proposed $50 million loan adding to the negative sentiment surrounding ADA. Combined with broader crypto market weakness, these factors are keeping ADA under pressure today. Is Cardano a good investment? Cardano (ADA) presents a mixed investment opportunity. It is a third-generation blockchain that aims to solve scalability issues and enhance security through its Proof-of-Stake mechanism. While some analysts predict significant price increases by 2030, others caution that it remains a high-risk investment given the volatility of the crypto market. Investors should consider their risk tolerance and research before investing, as Cardano’s future performance is uncertain and contingent on market conditions and technological advancements. Will Cardano recover? Cardano’s recovery potential depends on market sentiment and adoption. Despite past challenges, its projected price increase in 2026, potentially reaching $1, has significantly bolstered confidence in the coin’s future. Will Cardano reach $5? Cardano hitting $5 seems quite achievable given past levels. With its ATH around $3.10, $5 would only need to beat that peak by about 60%. A solid bull run and significant adoption could drive the unit price to $5. Will Cardano reach $10? Cardano hitting $10 is a long shot. Its all-time high was around $3.10 back in 2021, so $10 would mean more than tripling that peak. At current prices, that’s an over 13x jump. While crypto can be unpredictable, that would need massive adoption and a bull run far beyond what we saw in 2021. Will Cardano reach $50? Cardano hitting $50 is extremely likely. With ADA’s current supply of around 35 billion tokens, a $50 price would require a market cap of approximately $1.75 trillion. Even in crypto’s craziest bull runs, that kind of valuation doesn’t happen for altcoins. What is the Cardano forecast for 2040? Predicting Cardano’s (ADA) price in 2040 is highly speculative as it depends on multiple factors, including adoption, regulatory developments, technological advancements, and macroeconomic conditions. However, if Cardano continues to develop its smart contracts, decentralized applications (dApps), and blockchain efficiency, it could see widespread adoption, driving its price higher. Some optimistic projections suggest that ADA could reach double-digit prices, possibly ranging from $10 to $50 or more. However, in a bearish scenario, where regulatory hurdles and competition slow its progress, ADA could struggle to maintain high valuations. What will be the future price of Cardano in 2050? Predicting Cardano’s (ADA) price in 2050 is highly speculative, but if blockchain adoption continues to grow and Cardano successfully scales its smart contract ecosystem, its price could appreciate significantly. What that number will be remains to be seen. Does Cardano have a good long-term future? Cardano (ADA) has a positive long-term outlook, driven by its technological advancements and growing ecosystem. The platform’s unique features, such as its focus on scalability and partnerships with various institutions, position it well for future adoption. However, its success will depend on overcoming regulatory scrutiny and challenges related to developer engagement.

By 2027, Cardano’s price could trade at a maximum of $0.51. Cardano’s historic price sentiment Cardano price history by Coingecko ACH launched near $0.02 in 2020, surged to $0.1975 in August 2021, then slid below $0.10 by year’s end. During 2022 and 2023, it fell to $0.0133, later rebounded toward $0.049, but stayed volatile In 2024, it dropped to $0.0145, recovered above $0.02, and briefly reached $0.0397 in December. Early 2025 saw swings between $0.016 and $0.040, before weakening again toward $0.020 by mid-year. Late 2025 into early 2026 marked heavy losses to $0.0070–$0.0078, followed by stabilization near $0.0082. In early January 2026, Cardano traded between $0.36 and $0.38 as buyers sought to stabilize the price after the December decline and defend support in the mid $0.30s. By late January into February 7 price slipped toward roughly $0.33 to $0.34, showing continued corrective pressure and consolidation near a key support zone. Cardano traded around $0.40 on Jan 7, 2026, but steadily declined through the month, falling to roughly $0.29 by Feb 1 as selling pressure increased across the broader altcoin market. The price briefly recovered afterward, rising from about $0.25 on Feb 5 to around $0.27 on Feb 7, showing a short-term rebound after the early February dip. ADA began March around $0.29, attempting to stabilize after a sharp decline, with small consolidation candles forming near that level and a brief 5.8% surge on March 13 as broader crypto markets rallied — though the recovery lacked strong follow-through, with price still trading below all major moving averages throughout the month. By late March, Hyperliquid’s HYPE token flipped ADA in market cap on March 18, adding bearish sentiment, and ADA dropped 4.8% on March 25 as part of a worldwide market sell-off — ultimately closing the period around $0.24 by April 3, representing a decline of roughly 17% over the month. ADA entered April 1 around $0.24, having shed roughly 17% through March driven by broad market selling and bearish sentiment, with the month’s forecast range sitting between $0.2251 and $0.3252. By May 2, ADA was virtually flat at approximately $0.25, having spent the entire period consolidating in a narrow range with 50% green days and just 1.96% price volatility, reflecting a market stuck in indecision with no meaningful breakout in either direction.

Zcash patches critical flaws as crypto hacks hit $651M in one month
Today, May 2, 2026, the Zcash Foundation just released Zebra 4.4.0, urging all node operators to upgrade immediately after fixing multiple security flaws, including several that could have split the network’s consensus. The patch comes as April closes out as the worst month for crypto exploits so far. Blockchain security firm CertiK confirmed roughly $651 million in total losses across the industry. What kind of Zcash flaws does Zebra 4.4.0 fix? The update resolves five separate vulnerabilities in Zebra, the Rust-based Zcash node implementation built by the Zcash Foundation. Three of the bugs are consensus-critical, meaning that attackers could have exploited them and made Zebra nodes accept transactions that legacy zcashd clients would reject, thus splitting the network. The most severe issue (GHSA-28xj-328h-72vm) allowed a remote hacker to permanently stop a node from discovering new blocks with just one connection. The attack combined three weaknesses in how Zebra shared and downloaded information. According to the Zcash Foundation’s notice, the exploit “produced zero misbehavior score, zero bans, and zero disconnections,” thus making it invisible to standard monitoring tools. A second bug (GHSA-jv4h-j224-23cc) also made Zebra lose count of how many signatures were inside a block of transactions (it would usually count less than the 20,000-sigop block limit). Apparently, Zebra’s system ignored two specific types of scripts (the Coinbase input’s scriptSig, and P2SH signatures) during block validation. Because of this, an attacker could create a block exploiting both gaps, passing Zebra’s checks but failing on zcashd and creating a chain split. The third major issue (GHSA-gq4h-3grw-2rhv) happened because of a previous sighash fix that left stale data in a temporary storage area (buffer) readable across Zebra’s C++ foreign function interface. As such, an attacker could exploit this by using a valid signature to fill the buffer with correct information, and then send in a second transaction with an invalid hash type that would pass verification based on the leftover data. To resolve this, the Foundation applied a temporary fix that scatters the buffer with random bytes if a check fails, thus preventing the system from reusing old information until a permanent fix is deployed. The last two bugs caused disagreements between other parts of the system. One bug overloaded the network by making it use too much memory when reading messages (GHSA-438q-jx8f-cccv). The other was a minor coding discrepancy in how Zebra verified certain transactions (GHSA-cwfq-rfcr-8hmp). The Foundation noted the latter was not practically exploitable, but still went ahead to patch it to match zcashd behavior. Security researcher Sangsoo-osec was credited with discovering three of the five issues. Could the release have come at a better time? According to DeFiLlama , April 2026 was the most-hacked month in crypto history (by number of incidents), suffering an estimated 28 to 30 separate attacks. CertiK’s X post on April 30 put total losses at approximately $651 million, the highest since March 2022, excluding the Bybit breach in February 2025. Two incidents were responsible for most of the damage. On April 1, Drift Protocol lost about $285 million in a social-engineering operation linked to North Korea’s Lazarus Group. By April 18, KelpDAO had suffered its own $293 million message-spoofing exploit targeting a LayerZero cross-chain bridge, according to Cryptopolitan . Notably, none of April’s exploits targeted Zcash directly. But the sheer volume of attacks across chains reflects why its Foundation chose to label the Zebra update as “critical” and push for immediate adoption. What Zcash node operators should do The Foundation advises all operators to upgrade to Zebra 4.4.0 immediately, as the release doesn’t introduce any other significant changes beyond the security fixes. Node operators running older versions remain exposed to all five vulnerabilities, including the block-discovery halt that requires only a single malicious connection to execute. ZEC traded at $377.46 at the time of writing, according to CoinMarketCap, with a market cap of $6.28 billion.

Pi Network’s New Deadline: What Does the Next Big Update Mean for the PI Token
The team behind the controversial project has outlined the new deadline for the completion of the latest protocol update, version 23. At the same time, the native token has calmed at around $0.18 after the most recent volatility, but history shows that its fluctuations could return once the community anticipates new updates. V23 Is Coming Pi Network’s major protocol upgrades began in late February with the introduction of version 19.6. The following one, v19.9, arrived in early March, while perhaps the most significant, v20.2, which laid out the foundations for smart contract capabilities, was implemented by PiDay (March 14). The team continues with frequent protocol upgrades in April as well, with version 21 deployed at the beginning of the month, while, as reported earlier today, version 22 came at the end of the month, even though it was confirmed on May 1. The Core Team first only hinted at the next in its roadmap, version 23, and told the vast number of Nodes to wait for more information on the matter and it didn’t take long before it was announced. Earlier today, the only official X account linked to Pi Network said protocol update 23 will be implemented by May 15. As usual, all Nodes have to complete the necessary steps to ensure they are not disconnected from the network. The Pi Mainnet is upgrading to Protocol 23 – Deadline: May 15. All Mainnet nodes are required to complete this step before the deadline to remain connected to the network. This upgrade takes longer to complete, so plan accordingly. Details here: https://t.co/9VehO7hhj1 — Pi Network (@PiCoreTeam) May 2, 2026 Will PI Pump in Anticipation? The project’s native token has performed somewhat differently from the rest of the market, as it seems that it’s influenced mostly by internal activities rather than the overall crypto trend. Last week, while BTC and most alts stood still and even charted some losses, PI went on an impressive run , surging from $0.17 to $0.20. As the market began its post-FOMC recovery on Thursday, PI was rejected at that monthly high and slumped to $0.17. The gains coincided with growing anticipation for the announcement of the new protocol update, alongside another team statement regarding the completion of over 526 million tasks from a million verified users. As such, the question now is whether PI will outperform in the following weeks before version 23 is officially deployed.

New Document: Clarity Act Is a Positive Momentum for XRP
Crypto researcher SMQKE recently presented a structured comparison of three enterprise-oriented blockchain networks, focusing on how regulation and use cases may influence their progress. The post highlights what it describes as positive momentum for XRP, linking this outlook directly to developments surrounding the Clarity Act . The researcher states that this position is “documented,” indicating that the conclusion is based on observable developments rather than assumptions. The attached visual outlines a head-to-head comparison between XRP/XRPL, HBAR/Hedera, and the XDC Network. It focuses on two key areas: regulatory positioning and projected direction heading into 2026. The post places XRP at the center of the regulatory discussion, suggesting that recent policy direction in the United States is contributing to a more supportive environment. Clarity Act = Positive Momentum for XRP Documented. pic.twitter.com/mxqT2tCSdW — SMQKE (@SMQKEDQG) April 29, 2026 Regulatory Positioning Across Networks The comparison identifies regulatory alignment as a key factor across all three ecosystems. For XRP/XRPL, the post noted RLUSD being regulated by the New York Department of Financial Services . It also references momentum tied to the Clarity Act and notes the presence of AUDD on the XRPL. These points are presented as evidence of increasing clarity and compliance in the ecosystem. For Hedera, the post highlights its native ISO 20022 compatibility and its governing council model. These features are associated with strong enterprise trust and institutional appeal. In the case of the XDC Network, the post points to compliance with the Model Law on Electronic Transferable Records, alongside alignment to trade regulations in Asia, especially Hong Kong. It also mentions technical progress through upgrades such as the Cancun hard fork. The comparison shows that each network is pursuing regulatory alignment in different regions and through different approaches, while still aiming to attract enterprise adoption. 2026 Direction and Network Focus The post also outlines how each network is expected to develop by 2026. XRP/XRPL is linked to payments, stablecoin activity, and emerging decentralized finance yields within its ecosystem. Hedera is associated with governance-focused infrastructure and a shift from pilot programs to full-scale production. The XDC Network is presented as a participant in trade finance and real-world asset tokenization, supported by tokenized dollar volume. This comparison presents each ecosystem as focused on a specific area, while still operating within the same competitive environment. The XRP Community Input on Usage A response from Glenn Laborda adds another layer to the discussion. He states that usage itself represents positive momentum for XRP. This comment supports the idea that real activity on the network is an important measure of progress, alongside regulatory developments. Overall, the post and its response present XRP as benefiting from both policy developments and increasing use. The emphasis remains on measurable activity and regulatory clarity as factors influencing its position among enterprise blockchain networks.

Quantum Threats to Bitcoin: Paradigm Researcher Unveils Urgent PACT Model to Shield Dormant BTC
BitcoinWorld Quantum Threats to Bitcoin: Paradigm Researcher Unveils Urgent PACT Model to Shield Dormant BTC A researcher at crypto investment firm Paradigm has proposed a new model to protect dormant Bitcoin from future quantum computing threats. Dan Robinson introduced the provable address control timestamp (PACT) model. This model offers a way for Bitcoin holders to prove wallet ownership before quantum computers can derive private keys. The proposal directly addresses a key issue in the quantum-Bitcoin debate. Understanding the Quantum Threat to Bitcoin Quantum computing represents a significant future risk to Bitcoin’s security. Current Bitcoin addresses rely on cryptographic algorithms. These algorithms secure private keys. Quantum computers, once sufficiently advanced, could break this encryption. They could derive private keys from public addresses. This would allow attackers to steal funds from any wallet. This threat is especially acute for dormant Bitcoin addresses. These addresses hold coins that have not moved for years. They include the wallets of early adopters and potentially Satoshi Nakamoto himself. These coins are particularly vulnerable because their owners are unknown or inactive. They cannot upgrade their security. What is the PACT Model? Dan Robinson’s PACT model stands for provable address control timestamp. It uses the Bitcoin blockchain’s native timestamping system. Holders can prove their ownership of a specific address. They do this by signing a message with their private key. This message is then timestamped on the blockchain. The timestamp creates a permanent, verifiable record. This record proves that the holder controlled the address at a specific point in time. This proof exists before quantum computers become a real threat. It provides a defense against future claims or theft attempts. How PACT Works in Practice The process is straightforward. A Bitcoin holder signs a simple message. This message includes the current block height or a recent transaction hash. The holder then broadcasts this signed message to the network. Miners include it in a block. The block’s timestamp becomes the proof of ownership. This method does not require any changes to the Bitcoin protocol. It uses existing functionality. It is a non-invasive solution. It does not alter how Bitcoin works. It simply provides a new use case for existing features. The Significance for Dormant Bitcoin Addresses Dormant Bitcoin addresses hold a vast amount of wealth. Estimates suggest millions of Bitcoin sit in wallets untouched for years. These include coins belonging to early miners, investors, and possibly Satoshi Nakamoto. Protecting these assets is a major challenge. The PACT model offers a solution. It allows the true owners to prove their control. They can do this without moving their coins. This is crucial. Moving coins would reveal the owner’s identity. It could also trigger tax events or security risks. By creating a timestamped proof, owners establish a clear chain of custody. This proof can be used in legal disputes. It can also deter malicious actors. It shows that the address is actively monitored and protected. Expert Perspectives on the Proposal Industry experts have reacted with cautious optimism. Many see the PACT model as a practical first step. It does not solve the underlying quantum threat. However, it provides a crucial window of opportunity. “This is a clever use of Bitcoin’s existing infrastructure,” says Dr. Emily Carter, a cryptography researcher at MIT. “It creates a verifiable link between an address and its owner. This link can survive a quantum attack.” Other experts highlight the importance of timing. Quantum computers powerful enough to break Bitcoin encryption are likely years away. However, preparing now is essential. The PACT model allows holders to act proactively. Broader Implications for Bitcoin Security The PACT model has implications beyond dormant addresses. It could be used for any Bitcoin address. It provides a general method for proving ownership. This could be useful in many scenarios. For example, it could help in inheritance planning. Heirs could use timestamps to prove they control a deceased person’s wallet. It could also help in legal cases. It could prove that a specific address belonged to a specific person at a specific time. The model also raises questions about privacy. Signing a message links an address to a real-world identity. This could be a concern for privacy-focused users. However, the model is optional. Users can choose whether to use it. Timeline of Quantum Computing Development Quantum computing is advancing rapidly. Major tech companies like Google, IBM, and Microsoft are investing heavily. They have achieved significant milestones. 2019: Google claims quantum supremacy. Its Sycamore processor solves a problem in 200 seconds. A classical computer would take 10,000 years. 2023: IBM unveils a 1,121-qubit processor. This is a major step toward practical quantum computers. 2025: Researchers demonstrate quantum error correction. This is a key requirement for large-scale quantum computers. 2030 (estimated): Quantum computers may break current encryption standards. This includes Bitcoin’s ECDSA algorithm. This timeline shows the urgency. The threat is not immediate. However, it is approaching. The PACT model provides a way to prepare now. Comparison with Other Quantum Defense Proposals The PACT model is not the only proposal for quantum-proofing Bitcoin. Other approaches include: Proposal Method Key Advantage Key Disadvantage PACT Model Timestamped ownership proof No protocol changes needed Does not prevent future theft Quantum-Resistant Addresses New address format with stronger cryptography Long-term security Requires protocol upgrade Soft Fork to Change Signature Scheme Transition to quantum-safe signatures Full protection for all users Complex and risky implementation The PACT model is unique. It does not require consensus. It works with the current system. This makes it a practical interim solution. The Role of Paradigm in Bitcoin Research Paradigm is a leading crypto investment firm. It has a strong research arm. Dan Robinson is a well-known researcher. He has contributed to many Bitcoin and Ethereum improvement proposals. Paradigm’s involvement adds credibility to the PACT model. The firm has deep expertise in cryptography and blockchain technology. Its research is widely respected. This proposal is likely to receive serious consideration from the Bitcoin community. Practical Steps for Bitcoin Holders Bitcoin holders concerned about quantum threats can take action now. The PACT model provides a clear path. Generate a signed message: Use a Bitcoin wallet to sign a message proving ownership of your address. Include a recent block hash: This links the signature to a specific point in time. Broadcast the message: Send the signed message to the Bitcoin network. Miners will include it in a block. Store the proof: Keep a record of the transaction ID and block height. This is your proof of ownership. Repeat periodically: Create new timestamps over time. This strengthens your proof. This process is simple and secure. It does not require moving your Bitcoin. It does not expose your private key. It creates a verifiable chain of custody. Challenges and Limitations The PACT model is not a complete solution. It has limitations. Does not prevent theft: A quantum computer could still steal coins after the timestamp. The proof only shows prior ownership. Privacy concerns: Signing a message links an address to an identity. This may not be acceptable for all users. Requires proactive action: Holders must act before quantum computers become a threat. Many may not be aware of the risk. Legal recognition: The legal status of timestamped proofs is unclear. Courts may not accept them as definitive evidence. Despite these limitations, the model is a valuable tool. It provides a foundation for future solutions. It also raises awareness about the quantum threat. Conclusion Dan Robinson’s PACT model offers a practical way to protect dormant Bitcoin from future quantum threats. It uses Bitcoin’s existing timestamping system. It creates a verifiable proof of ownership. This proof can be used to defend against quantum attacks. The model is a significant contribution to the quantum-Bitcoin debate. It provides a proactive solution for holders. It does not require protocol changes. It is a simple, effective, and timely proposal. As quantum computing advances, such models will become increasingly important. The Bitcoin community should consider this proposal seriously. FAQs Q1: What is the PACT model? A1: The PACT model, or provable address control timestamp, is a method for Bitcoin holders to prove they own a wallet by creating a timestamped record on the blockchain. This proof can protect against future quantum computing attacks. Q2: How does the PACT model protect against quantum threats? A2: It creates a verifiable record that a specific address was controlled by a specific person at a specific time. This record can be used to prove ownership even if a quantum computer later derives the private key. Q3: Who proposed the PACT model? A3: Dan Robinson, a researcher at the crypto investment firm Paradigm, proposed the PACT model. The Block reported on his proposal. Q4: Does the PACT model require changes to the Bitcoin protocol? A4: No, it does not. It uses Bitcoin’s existing functionality, specifically the ability to sign messages and have them included in blocks. This makes it a non-invasive solution. Q5: Is the PACT model a complete solution to the quantum threat? A5: No, it is not a complete solution. It provides a way to prove prior ownership but does not prevent future theft. It is best seen as an interim measure while more permanent solutions are developed.
