Coinbase Flags Algorand and Aptos as Leaders in Quantum-Ready Crypto
Coinbase is sounding the alarm on a future risk that could reshape blockchain security: quantum computing.
In a new report, its quantum advisory board highlighted how some networks are preparing early, while others may face greater challenges down the line.
Quantum Threat Not Here Yet, But Inevitable
Coinbase researchers emphasized that quantum computers capable of breaking blockchain cryptography do not yet exist, but likely will in the future.
Such machines could:
- Break private key cryptography
- Access crypto wallets
- Undermine blockchain security models
The board believes it is only a matter of time before this level of computing power becomes reality.
Algorand Leading in Quantum Readiness
Algorand was highlighted as one of the most prepared networks.
Key strengths include:
- A staged roadmap toward quantum resistance
- Existing support for quantum-secure accounts
- Successful quantum-resistant transactions on mainnet
However, some areas like validator coordination and block proposals still require upgrades.
Aptos Also Well Positioned
Aptos was also identified as a strong contender in the transition to post-quantum security.
Its design allows users to:
- Update their authentication keys easily
- Transition to quantum-safe cryptography without moving funds
- Maintain the same account structure
This flexibility could make upgrades smoother compared to other networks.
Proof-of-Stake Chains Face Higher Risk
The report warned that major proof-of-stake networks like:
- Ethereum
- Solana
may be more exposed due to how validator signatures are structured.
That said:
- Solana is already developing improved signature schemes
- Ethereum has a roadmap to adopt quantum-resistant cryptography
What Happens to Vulnerable Wallets?
One of the more controversial ideas discussed is how to handle existing wallets.
Potential solutions include:
- Encouraging users to migrate to quantum-safe wallets
- Revoking access to vulnerable wallets
- Treating un-upgraded funds as permanently inaccessible
This raises major questions about user responsibility and network governance.
A Long-Term, Not Immediate Risk
Despite the warnings, Coinbase stressed that a quantum computer capable of breaking crypto would need to be:
- Far more powerful than current systems
- Likely at least a decade away
Still, the report urges developers to begin preparing now rather than waiting.
Preparing for the Next Era of Security
The takeaway is clear: quantum computing may not be an immediate threat, but it is a structural risk that cannot be ignored.
Networks like Algorand and Aptos are taking early steps, while others are still developing their strategies.
How the industry responds could determine whether crypto remains secure in a post-quantum world.

DoorDash to Enable Stablecoin Payments Across Global Platform
DoorDash is stepping into crypto-powered payments, planning to integrate stablecoins for users, merchants, and delivery drivers across its ecosystem.
Stablecoins Coming to Everyday Payments
The initiative is being built in partnership with the Tempo blockchain, aiming to allow:
- Customers to pay using stablecoins
- Merchants to receive faster settlements
- “Dashers” to get paid more quickly
The rollout is expected to cover users in more than 40 countries, signaling a major step toward mainstream crypto adoption.
Why Stablecoins?
DoorDash and its partners are focusing on three key advantages:
- Faster payouts compared to traditional banking
- Lower cross-border costs
- Greater flexibility in payments
According to DoorDash leadership, improving payout speed for drivers and merchants is a major motivation behind the move.
Backed by Major Financial Players
The integration involves several key partners:
- Stripe
- Paradigm
- Coastal Bank
- ARQ
This collaboration highlights growing alignment between traditional finance and blockchain infrastructure.
A Massive Use Case for Crypto
DoorDash operates at enormous scale:
- 903 million orders in Q4 2025
- Around $29.7 billion in transaction volume
Integrating stablecoins into a platform of this size could significantly accelerate real-world crypto usage.
Stablecoins Enter Mainstream Commerce
This move reflects a broader industry trend:
- Visa and Mastercard are expanding stablecoin infrastructure
- Stripe continues investing heavily in blockchain payments
- Financial institutions are exploring tokenized settlement systems
Stablecoins are increasingly being positioned as the bridge between crypto and everyday payments.
From Crypto Niche to Daily Utility
Unlike speculative crypto use cases, this integration targets real-world transactions:
- Food delivery payments
- Gig economy payouts
- Merchant settlements
This could make stablecoins part of daily financial activity for millions of users.
A Turning Point for Adoption?
If successful, DoorDash’s integration could mark a key shift:
- From crypto as an investment to crypto as a payment layer
- From niche users to mass-market adoption
It also reinforces the idea that stablecoins may become the default digital payment rail for global commerce.

France Backs Euro Stablecoins to Challenge US Dollar Dominance
France’s finance minister, Roland Lescure, has voiced support for a euro-pegged stablecoin initiative led by European banks, as the region looks to compete with the dominance of US dollar-backed tokens.
The proposed stablecoin, known as Qivalis, is expected to launch in the second half of 2026 under the European Union’s Markets in Crypto Assets regulatory framework.
Europe Pushes for Digital Euro Alternatives
The Qivalis project was introduced in September 2025 by a group of major European banks, including ING and UniCredit.
Its goal is to create a MiCA-compliant euro stablecoin that can serve as a regional alternative to widely used dollar-backed digital assets.
Lescure expressed strong support for the initiative, stating that Europe needs its own competitive offering in the stablecoin space.
Dollar Stablecoins Still Dominate
Currently, the stablecoin market is heavily dominated by US dollar-pegged assets.
Tether’s USDT and Circle’s USDC account for the vast majority of market share, with USDT alone holding a market capitalization of around $186 billion.
By comparison, euro-backed stablecoins represent only a small fraction of the market, which Lescure described as “not satisfactory.”
Tokenized Deposits Also Encouraged
In addition to stablecoins, Lescure encouraged banks to explore tokenized deposits as part of the broader digital finance shift.
These instruments, which represent traditional bank deposits on blockchain infrastructure, could play a complementary role alongside stablecoins in modernizing financial systems.
Europe Focuses on Regulation and Stability
European regulators are taking a structured approach through the MiCA framework, aiming to ensure compliance, transparency, and financial stability.
At the same time, officials remain cautious about certain features, particularly interest-bearing stablecoins.
Banque de France Governor François Villeroy de Galhau has warned that offering yield on stablecoins could pose risks to financial stability, a concern echoed by policymakers in both Europe and the United States.
Ongoing Debate in the US
The discussion around stablecoins is also ongoing in the US, where lawmakers are still debating how to regulate the sector.
The proposed CLARITY Act, which aims to establish a market structure for crypto assets, remains stalled in the Senate amid disagreements over issues like stablecoin yield and tokenized equities.
Europe Looks to Close the Gap
With initiatives like Qivalis, Europe is positioning itself to reduce reliance on dollar-based stablecoins and strengthen the role of the euro in digital finance.
As competition intensifies, the development of regulated, region-specific stablecoins could play a key role in shaping the future of global payments.
