Immutability
Short answer: Immutability means data can't be altered, since changing one block invalidates all after it. Learn how many confirmations make a SynX transfer final.
Definition
Immutability means data cannot be altered or deleted once recorded. In blockchains, immutability comes from cryptographic linkingโchanging any block invalidates all subsequent blocks, making tampering computationally infeasible without controlling the majority of network resources.
Technical Explanation
Each block contains the hash of the previous block. Modifying old data changes that block's hash, breaking the chain. An attacker must recalculate every subsequent block's proof-of-work faster than honest miners extend the chainโrequiring majority hashrate (51% attack).
Immutability strengthens over time: as more blocks confirm a transaction, reversing it becomes exponentially harder. After sufficient confirmations, transactions are practically irreversible, creating trust without requiring trust in any party.
SynX Relevance
SynX combines immutability with quantum-resistant cryptography. No known quantum attack forges the SPHINCS+ signatures protecting SynX transactions, and no elliptic-curve key has ever controlled a SYNX coin.
Frequently Asked Questions
- Can blockchain data ever be changed?
- Technically possible with majority attack, but computationally prohibitive on healthy networks.
- How many confirmations make transactions immutable?
- More confirmations mean stronger immutability. Six is common; security needs vary.
- Does quantum computing threaten immutability?
- For classical chains, possibly. SynX's post-quantum design maintains immutability guarantees.
