Prosumer provers
The prosumer tier sits between hobby (laptop/NAS, < 100 TB) and enterprise (data center, multi-PB). Typical setup: a home rack or a small server in a colocation closet, 100 TB to 5 PB of storage, ~1 Gbps symmetric.
This is the sweet spot for someone who wants to make storage their actual side income or a small business. Earnings scale linearly with bytes proven.
Who this is for
- An operator with 100 TB to 5 PB of usable disk
- Symmetric 1 Gbps (residential fibre or business connection)
- Comfortable with Linux, systemd, ZFS or similar redundancy
- Willing to commit 12+ months of operation
What you get
| Prosumer tier | |
|---|---|
| Min usable disk | 100 TB |
| Min stake | 100 PROVA × committedGiB (with USDC-equivalent floor) |
| Recommended hardware | Bare metal server, ECC RAM, ZFS or RAID-Z2, separate redundant network |
| Setup time | 1–2 days (including hardware burn-in) |
| Realistic capacity | 100 TB – 5 PB |
| Identity attestation | wallet active 90+ days, optionally SBT or ENS subdomain (not full KYC) |
Setup overview
The CLI install is the same as hobby tier:
curl -fsSL https://get.prova.network/prover | shDifferences from hobby tier:
- Multiple disks via ZFS pool.
provadcan map multiple physical disks into one logical pool. Configure inprover.tomlunder[storage]. - Dedicated network interface. Recommend a separate NIC for proof traffic so retrievals don't impact proof submissions during peak.
- Rate-monitor your stake. At 1 PB committed, your stake is in the millions of PROVA. Set up alerts when the USDC-equivalent floor moves close to your minimum (the stake-floor oracle).
- Multi-region announce. If you have presence in multiple regions, register multiple provers (one per region) under separate wallets. Each will earn proportionally.
Hardware notes
| Component | Recommended | Notes |
|---|---|---|
| CPU | 8+ cores, modern x86 or ARM | Storage is disk-bound, not CPU-bound. Older 8-core Xeons work fine. |
| RAM | 64 GB ECC | ZFS likes RAM. ECC catches silent corruption. |
| Disk | NVMe metadata + spinning rust for bulk | NVMe for the ZFS metadata special-vdev; HDDs for the bulk. |
| Network | 1 Gbps symmetric, real bandwidth | Asymmetric "1 Gbps down / 50 Mbps up" residential is not enough. |
| Power | UPS, 60+ minute runtime | Sustained outages cause missed proofs and slashing. |
Cost estimate for a 1 PB prosumer setup (mid-2026 prices):
- HDDs: $9,000–14,000 (1 PB usable from raw with ZFS Z2)
- NVMe (metadata + L2ARC): $400
- Server (used Dell R730 or similar): $1,500
- Network: $0 (existing fibre) – $200/mo (business circuit)
- Power: ~$50–80/mo
- One-time: $11,000–16,000
- Monthly: $50–280
Earnings model
Same as hobby tier — you earn USDC per deal proven, plus PROVA emission proportional to bytes proven. The emission curve is published; the Earnings page has worked examples for prosumer scale.
A 1 PB prosumer at 70% utilisation, $2.50/TB-month effective price, 99.5% proof success:
USDC monthly: 1 PB × 1024 TB × 0.70 × $2.50 = $1,792 USDC
PROVA monthly: ~ 1 PB / total network committed × monthly_emissionThe PROVA emission share scales with your fraction of total committed bytes on the network. Early provers earn a larger absolute share because the network is small; this is intentional.
Slashing exposure
Prosumer tier has substantially more capital at risk than hobby. A 1 PB prover with the default slashFraction = 10% and slashPerFault = 50 PROVA is hit for ~50 PROVA per individual missed proof, and up to 10% of total locked stake per fault event.
Practical implication: at 1 PB you have ~10M PROVA staked. A serious cluster failure (e.g. ZFS pool degraded for 24 h producing missed proofs) could cost up to 1M PROVA. Set up monitoring before you scale above 100 TB.
The protocol's stake-floor oracle gives you a 7-day grace window to top up stake if PROVA's USD price drops; use this window, don't ignore the alert.
Identity attestation
Above 100 TB committed, the protocol requires lightweight identity attestation (not full KYC). Options, any one suffices:
- An ENS name with verified contenthash and an ENS-resolver TXT record claiming this prover wallet
- An EAS attestation (Ethereum Attestation Service) signed by a published attester
- A 30-day continuous on-chain history showing legitimate activity
This is to discourage Sybil — the same person spinning up 50 prosumer provers from the same hardware to capture a larger emission share.
Operational discipline
- 24/7 monitoring. Prometheus + Grafana setup recommended. The official
provadGrafana dashboard is included. - Alerting. Set up PagerDuty / OpsGenie / opsgenie / your phone for: missed proofs, disk errors, network partition, stake-floor breach.
- Quarterly capacity review. Plan disk growth. Adding capacity requires re-registering with the new committed bytes and topping up stake.
- Annual disk replacement budget. HDDs fail. Replace SMART-warning drives within 7 days.
