## Cloud Rewards and Quantum Threats: How Algorand and Aptos Are Paving the Way for Green Crypto
As the world becomes increasingly dependent on digital transactions, the threat of quantum computing to the security of our online assets is a growing concern. The emergence of powerful quantum computers could potentially break the cryptography that secures digital assets across major blockchains, leaving users vulnerable to attacks. However, some blockchain networks are taking proactive steps to mitigate this threat, and their efforts could have a significant impact on the future of sustainable and secure digital transactions.
The work of Algorand and Aptos, two layer-1 blockchain networks, has been highlighted by Coinbase’s quantum researchers as exemplary in preparing for the potential threats of quantum computing. Algorand, in particular, has developed a staged roadmap toward full quantum readiness, deploying cryptography designed to be secure against quantum computers. This means that users can create quantum-resistant accounts without requiring protocol modifications, providing an additional layer of security for their digital assets. Recently, Algorand completed its first quantum-resistant transaction on mainnet, a significant milestone in its efforts to secure its network against quantum attacks.
Aptos, another competing layer-1 blockchain, is also well-positioned for the transition to post-quantum secure transactions. On Aptos, users can easily update their authentication key to a post-quantum public key, ensuring that their assets are secure without needing to move them to a new account. This simplicity and flexibility make Aptos an attractive option for users looking for a secure and sustainable blockchain network. The fact that both Algorand and Aptos are taking proactive steps to address the quantum threat is a positive development for the future of green crypto and cloud rewards.
Algorand and Aptos more prepared for quantum
However, not all blockchain networks are as prepared. Proof-of-stake blockchains, including Ethereum and Solana, may be at greater risk to quantum computing due to the signature schemes validators use to secure the network. This vulnerability could have significant implications for the security of user assets and the overall sustainability of these networks. Fortunately, both Solana and Ethereum are taking steps to address this issue, with Solana creating a new signature scheme and Ethereum planning to upgrade its signatures to be quantum-resistant.
The threat of quantum computing to blockchain networks is a pressing concern, but it’s not an immediate one. According to Coinbase’s report, a computer powerful enough to threaten crypto would need to be orders of magnitude more powerful than anything available today, which could take at least a decade. Nevertheless, the fact that networks like Algorand and Aptos are taking proactive steps to prepare for this threat is a positive development for the future of sustainable and secure digital transactions. As the world becomes increasingly dependent on digital assets, the importance of secure and green crypto solutions will only continue to grow.
In the context of passive rewards and cloud rewards, the security of blockchain networks is paramount. Users need to feel confident that their assets are secure in order to participate in these systems, and the threat of quantum computing could undermine this confidence. However, by prioritizing sustainability and security, blockchain networks like Algorand and Aptos are helping to create a more secure and sustainable future for digital transactions.

Coinbase said that Aptos, a competing layer-1 blockchain, was “well positioned for the transition to post-quantum secure transactions.”
It explained that on Aptos, a user’s public key is stored as metadata associated with the account, and a user’s address isn’t derived from the hash of the user’s public key.
“Users who want to become post-quantum secure need only sign a transaction that updates their authentication key to a post-quantum public key,” Coinbase said. “There is no need to move assets to a new account.”
Proof-of-stake chains may be at greater risk
Coinbase warned that proof-of-stake blockchains, including Ethereum and Solana, may be at greater risk to quantum computing because of the signature schemes validators use to secure the network, according to the board.

However, Coinbase acknowledged that Solana has created a new signature scheme, and users can move their tokens to a new address based on the upgraded scheme and will be “no longer exposed to a quantum attacker.”
Ethereum, too, “has a clear roadmap to address this in the near future,” Coinbase said, which includes upgrading signatures to be quantum-resistant.
The report also discussed how networks could deal with quantum-vulnerable tokens and wallets, suggesting that blockchains could tell their users to migrate to quantum-proof wallets and that wallets with assets that are quantum-vulnerable would be revoked and lost forever.
However, the board said that the threat of quantum computing “doesn’t exist yet,” as a computer that could threaten crypto “would need to be orders of magnitude more powerful than anything available today,” which could take at least a decade.
