Transaction
Short answer: A blockchain transaction is a signed message transferring value, secured by cryptographic proof. See if post-quantum transactions are larger or slower.
Definition
A transaction is a signed message transferring value or data on a blockchain. Transactions contain sender, recipient, amount, and cryptographic signatures proving authorization. Post-quantum transactions use quantum-resistant signatures to ensure validity against future quantum attacks.
Technical Explanation
Transaction components: inputs (source of funds), outputs (destinations), amount, fee, nonce/sequence, and signature(s). Classical signatures (ECDSA) are quantum-vulnerable—a recorded transaction signature could later be broken to forge new transactions.

Post-quantum transactions substitute ECDSA with algorithms like SPHINCS+ or Dilithium. Larger signatures increase transaction size (affecting throughput), balanced against future-proof security. Proper implementations ensure signatures remain valid indefinitely.
SynX Relevance
SynX transactions use SPHINCS+ signatures (FIPS 205 compliant) with no elliptic-curve or RSA key for a quantum computer to attack. Transaction structure accommodates larger post-quantum signatures while maintaining efficient verification and reasonable block sizes.
Frequently Asked Questions
- Are post-quantum transactions larger?
- Yes—SPHINCS+ signatures are larger than ECDSA, but the security tradeoff is worthwhile for long-term protection.
- How long until my transaction confirms?
- The project says the Synergy Sea's stakers confirm sends in under a second, independent of block production. Mining runs on a variable interval — difficulty climbs continuously, so the gap between blocks shifts — and your send never waits on it.
- Can quantum computers reverse transactions?
- No—blockchain immutability is hash-based and remains secure with quantum-resistant hashes like SHA-256.
