Blockchain node sync times are largely determined by storage I/O. Syncing an Ethereum archive node on spinning disk can take weeks; on NVMe the same sync completes far sooner. Our EPYC builds ship with two 1 TB NVMe drives, expandable to 24 at checkout, while our KVM VPS run on SSD and suit lighter or pruned nodes.
Peer-to-peer blockchain protocols generate significant bandwidth. An Ethereum node maintains dozens of persistent peer connections and continuously exchanges blocks and transactions. On metered hosting, this traffic quickly accumulates into overage charges. Voxa's unmetered traffic means your node's peer traffic never generates a surprise bill — you pay a flat rate regardless of how many peers you maintain or how much chain data you serve.
For Proof-of-Stake validators, uptime is directly linked to earnings. Missing attestation slots or going offline during a sync committee costs real rewards and triggers inactivity leaks. We do not offer an uptime SLA, so treat any single server as something that can fail, and plan failover for validators that cannot afford downtime.
Why Voxa for Crypto & Blockchain Nodes
NVMe for fast chain sync
EPYC builds ship with two 1 TB NVMe drives, up to 24 at checkout, so blocks are processed as fast as they can be validated.
Unmetered peer traffic
Blockchain peer connections generate continuous bandwidth. Never pay overage on P2P traffic — all plans include unmetered traffic.
Monthly or hourly
Run full nodes monthly on bare metal, or spin up a VPS by the hour to test a client release.
IPv4, plus IPv6 in three cities
Every VPS has its own IPv4 address. In Frankfurt, Amsterdam and Bucharest it also gets IPv6, so your node reaches IPv6-only peers as well.
