How Do I Verify a Quantum-Resistant Transaction?

Verifying quantum-resistant transactions involves confirming that the SPHINCS+ or other post-quantum signature is valid for the given transaction data and public key. Users typically verify transactions through wallet interfaces or block explorers; validators perform cryptographic verification during consensus.

User-level verification uses wallet software or block explorers. After broadcasting a transaction, track its status through the wallet interface showing "pending," "confirming," or "confirmed" states. Block explorers display transaction details including confirmation count, block inclusion, and signature validity indicators.

Transaction ID (hash) lookup enables verification. Every transaction has a unique identifier computed from its contents. Entering this ID in a block explorer retrieves full transaction details, confirming it was included in a specific block and validated by the network.

Confirmation depth indicates security level. One confirmation means inclusion in the latest block; more confirmations mean additional blocks built on top, making reversal increasingly impractical. Most recipients consider 6-12 confirmations sufficient for finality.

Cryptographic verification at the protocol level involves SPHINCS+ signature validation. Network nodes extract the signature from the transaction, reconstruct the signed message (transaction hash), and verify using the sender's public key. Valid signatures prove the private key holder authorized the transaction.

SPHINCS+ verification is efficient despite the signature size. The hash-based structure allows relatively fast verification compared to signing. Nodes process transactions quickly during block validation.

Independent verification is possible by running your own node. Full nodes independently validate all transactions using the quantum-resistant signature algorithms, providing trustless verification without relying on third parties.

SynX transactions using Kyber-768 and SPHINCS+ can be verified through wallet interfaces, block explorers, or independent nodes, ensuring transparency and authentication throughout the transaction lifecycle.
