- Custom on-chain verification mechanisms
PRESS RELEASE — Instanodes, a blockchain infrastructure provider offering RPC endpoints across over 50 blockchain networks, dedicated nodes, validators, and rollup infrastructure, today announced post-quantum account engineering for Ethereum Virtual Machine (EVM)-compatible networks and Solana.
The expanded offering also includes quantum-readiness assessments and custom cryptographic engineering services for businesses evaluating their existing account security architectures.
Preparing Blockchain Accounts for Future Quantum Risks
Blockchain accounts primarily rely on elliptic-curve cryptography for transaction authorization. However, advancements in quantum computing research have raised concerns about the long-term security of existing blockchain security architectures.
Research from Google Quantum AI (March 2026) and IonQ (September 2026) demonstrated the potential impact of future fault-tolerant quantum computers on widely used cryptographic methods.
For businesses managing digital assets, these developments underscore the need to:
- Evaluate existing blockchain security solutions
- Prepare for potential cryptographic vulnerabilities
Post-Quantum Account Implementations for Ethereum and Solana
Instanodes has developed and tested post-quantum account implementations for Ethereum and Solana, utilizing hash-based digital signatures for account-level authorization. These implementations are designed to reduce reliance on traditional elliptic-curve signatures within account-level asset authorization, with verification mechanisms adapted to each blockchain’s execution environment.
On Ethereum, post-quantum signature verification can be integrated into programmable smart-account architectures, including ERC-4337, which supports custom signature-validation logic. On Solana, similar account designs require custom program-level signature verification and asset-control mechanisms. However, these implementations do not replace Solana’s native transaction-signature infrastructure, which continues to use Ed25519.
Quantum-Readiness Services for Blockchain Businesses
Instanodes is expanding its blockchain infrastructure services to help businesses assess cryptographic vulnerabilities and prepare for emerging security requirements. Its specialized offerings include:
- Post-Quantum Account Engineering
- Quantum-Readiness Assessments
- Custom Cryptographic Engineering Services
