Private cash, mined on ordinary computers.
NERVA is digital cash forked from Monero in 2018, engineered so that only CPUs can mine it: no GPUs, no ASICs, no pools. Ring signatures hide the sender, RingCT hides the amount, one-time addresses hide the receiver. This world is your window onto the network, with a live explorer, telemetry and payment links.
Proof-of-work is essentially one-CPU-one-vote
Satoshi Nakamoto · Bitcoin whitepaper
NERVA launched on 1 May 2018 as a fork of Monero built on a single conviction: when mining can be industrialised, money becomes centralised. GPUs, ASICs and mining pools quietly turn one-CPU-one-vote into one-datacenter-one-vote. NERVA simply refuses that future.
Its CryptoNight-Adaptive algorithm is re-tuned whenever hardware starts drifting toward dominance. The v6 revision, activated in hard fork v13, widens the memory-latency gap that keeps GPUs and ASICs unprofitable. Miners work solo through their own full node, so there is no pool operator to trust and no hashrate rental market to fear.
Privacy is inherited from the CryptoNote lineage. Ring signatures, RingCT and one-time addresses mean an observer sees neither who sent, nor who received, nor how much. The chain is a crowd, not a ledger of names.

The chain is a crowd, not a ledger of names
Every transaction is signed by a ring of five possible spenders. The real signer is computationally indistinguishable from the decoys the wallet picks automatically from the chain.
Amounts are sealed with Pedersen commitments. The network proves no coins were created out of thin air without ever seeing a balance.
Each transfer derives a unique stealth address on the receiver side. Addresses cannot be reused, so nothing links two payments to the same person.
There is no transparent mode to opt out of. Every transaction is private, for everyone, by default.
Secured by ordinary computers
CryptoNight-Adaptive v6 is tuned for the CPU in the device you are reading this on. LWMA difficulty retargets smoothly every block, and solo mining requires running a full node, tying security directly to decentralisation. No pool operator stands between you and the network, and the hardware you already own is competitive.

Mining runs through the official CLI or NervaOne; this interface itself only reads the chain.
Everything runs client-side: nothing to hack, nothing to custody
The Nerva side of XelisVault is an independent window onto the network, built in the spirit of the protocol itself: no accounts, no tracking, no keys, no third-party scripts. Here is exactly what happens under the hood.
This interface talks straight to the public NERVA explorer API (api.nerva.one) from your browser. It never holds a seed, a spend key or a view key. There is nothing here to steal.
Height, difficulty, blocks and the mempool are polled every few seconds, the same public feed the official explorer uses. The block ticker at the top of this page is the actual chain.
NervaLink invoices live entirely inside their URL. The pay page watches the chain for your invoice reference and follows it from the mempool to 10 confirmations, with no account, no database and no server.
RingCT amounts are encrypted. Payment detection confirms that your invoice reference appeared on-chain with enough confirmations; it cannot read the exact amount paid. Your wallet (NervaOne or the CLI) shows the amount paired with the reference for final reconciliation. Recent wallet versions may require enabling long payment ids for URI payments, so the pay page always offers the plain address as a fallback.

The wider NERVA world
Two protocols. One standard: privacy
You are standing in the Nerva world of XelisVault. The Xelis world holds the confidential BlockDAG platform: xUSD, VLT, VaultSwap and the vault app itself. Cross back any time; the gate remembers nothing.
