Instanodes Offers Post-Quantum Account Engineering for Ethereum and Solana
Instanodes is now offering post-quantum account engineering for both Ethereum Virtual Machine (EVM)-compatible networks and Solana, in response to growing concerns about the future security of blockchain transactions. Research published by Google Quantum AI in March and IonQ in September this year detailed updated resource estimates for fault-tolerant quantum computers and their potential to compromise current cryptographic methods.
Instanodes, which already supports over 50 blockchain networks through its RPC endpoints and node infrastructure, aims to assist businesses in evaluating and strengthening their account security against these emerging quantum threats. The company emphasizes the need to reassess existing blockchain security solutions in light of these developments.
Ethereum and Solana Account Security via Hash-Based Signatures
Instanodes has deployed post-quantum account implementations for both Ethereum and Solana, utilizing hash-based digital signatures to authorize accounts and reduce reliance on vulnerable elliptic-curve cryptography. These implementations are tailored for integration into existing wallet, custody, and protocol architectures, adapting verification mechanisms to each blockchain's execution environment. On Ethereum, Instanodes integrates post-quantum signature verification into programmable smart-account architectures like ERC-4337, enabling custom signature validation logic.
While Solana continues to use Ed25519 for native transaction signatures, Instanodes takes a layered approach, involving custom program-level signature verification and asset-control mechanisms. This approach allows businesses to explore alternative cryptographic methods for account security and prepare their infrastructure for the growing capabilities of quantum computing.
Instanodes offers quantum-readiness assessments to help organizations identify vulnerabilities within their cryptographic dependencies and create migration roadmaps. These assessments, coupled with custom cryptographic engineering services, cater to the specific needs of exchanges, custodians, and blockchain protocols.
In addition to account implementations and assessments, Instanodes provides a range of blockchain infrastructure services, including:
- RPC endpoints
- Dedicated nodes
- Validator infrastructure
- Dedicated blockchain environments across over 50 networks
These services aim to support organizations in transitioning to quantum-resistant security measures and protecting their digital assets from future threats.
