Block confirmations refer to the process where miners add your transaction to blocks (data blocks) on the blockchain during deposits or withdrawals. This critical step ensures transaction immutability and network security.
Why Block Confirmations Matter
When you initiate a deposit:
- Your transaction enters the mempool (pending pool)
- Miners verify and include it in a block (1st confirmation)
- Each subsequent block added to the chain increases confirmation count
Key security benefits:
- Higher confirmations = greater resistance to tampering
- Reduced risk of double-spending attacks
- Final settlement assurance
Different cryptocurrencies require varying confirmation thresholds based on their:
- Consensus mechanisms (PoW, PoS, etc.)
- Network security parameters
- Risk tolerance levels
How to Check Confirmation Status on OKX
Follow these steps to monitor your transaction:
- Launch the OKX app and select Deposit
Choose your:
- Cryptocurrency (BTC, ETH, etc.)
- Deposit network (ERC-20, TRC-20, etc.)
Locate the required confirmation count under:
- Account Crediting section

FAQs
Q: Why does Bitcoin need 6 confirmations?
A: This provides 99.9% probability against chain reorganization attacks.
Q: Can transactions fail after confirmations?
A: Extremely rare - only possible during 51% attacks, which require immense computational power.
Q: How to speed up confirmations?
A: Increase transaction fees to incentivize miner priority.
Q: Why do exchanges require more confirmations than wallets?
A: Exchanges handle higher volumes and implement additional security buffers.
Q: Are confirmations needed for PoS networks?
A: Yes, but typically fewer (e.g., 12 for Ethereum post-Merge).
Q: What if my transaction gets stuck?
A: Use OKX's transaction accelerator or RBF (Replace-By-Fee) options.

Best Practices for Secure Transactions
Always verify:
- Destination addresses
- Network compatibility
- Minimum deposit amounts
Monitor confirmation progress via:
- Exchange dashboards
- Blockchain explorers
- Network status pages
Understand your asset's:
- Average block time
- Confirmation requirements
- Reorg resistance
Remember: Higher-value transactions warrant waiting for additional confirmations as an extra security measure.
