What we collect, why we collect it, and how long we keep it.
DrillHash is a public mining pool for the NEXA blockchain. The pool is designed to operate with minimal data collection. No account registration is required. Your wallet address serves as your sole identifier on the service.
The pool collects only the data required for mining pool operation and payment processing:
| Data | Purpose | Retention |
|---|---|---|
| Worker name | Share tracking and hashrate reporting | 35 days |
| Share difficulty & nonce | PPLNS reward calculation | 35 days |
| Timestamp | Share ordering and PPLNS window | 35 days |
| Miner type | Protocol compatibility (INIBOX vs GPU) | 35 days |
| Wallet address | Identity, balance tracking, payouts | Permanent |
| Block height & hash | Block records and reward distribution | Permanent |
| Payout TXID | Payment verification and audit trail | Permanent |
Share records are automatically purged every 24 hours. Records older than 35 days are permanently deleted from the database. Temporary session data stored in cache expires within 7 days. Mining job templates are held in memory only and are not persisted to disk.
Block records and payment history are retained permanently for operational transparency and to enable users to verify their transaction history.
Your NEXA wallet address is extracted from your miner configuration (the user field in your Stratum connection) and is used to:
Your wallet address is public on the NEXA blockchain. Displaying it on the pool dashboard does not expose any additional private information.
Payouts are processed automatically on a recurring schedule. Each payment is recorded on the NEXA blockchain with a transaction ID. Payment records (wallet address, amount, transaction ID, timestamp) are retained permanently as part of the public blockchain ledger and the pool's internal audit trail.
The pool connects to the NEXA blockchain network for mining and payment operations. Data shared with the NEXA network is subject to that network's own protocols and is outside the scope of this policy.
Pool communications use standard Stratum protocol over TCP. Database access is restricted to pool operations. No data is sold, shared with third parties for marketing purposes, or used for advertising.
This policy may be updated from time to time. The "Last updated" date at the top of this page reflects the most recent revision. Continued use of the pool after changes constitutes acceptance of the updated policy.
