VERIFICATION NODE PROGRAM · CHAIN ID 2800

Help run the chain nobody owns.

AERE settles in half a second with mathematical finality. The consensus is sound. The operator set is not yet wide enough — and we are recruiting the independent organizations who will change that.

Where we are today — plainly

AERE runs on three verification nodes, and all three are operated by the AERE Foundation. That is centralized operation of a sound protocol, and we will not dress it up as anything else. With three nodes, QBFT consensus keeps every block consistent and final — but the failure of a single node pauses block production until it returns, and institutional reviewers correctly treat a one-operator set as a single point of trust.

This program exists for exactly one reason: to move the network from 3 Foundation-operated nodes to 7 independently operated nodes, with named, publicly identified organizations running infrastructure the Foundation does not control — and from there to 21.

What a verification node does

AERE is an EVM network running QBFT consensus — a Byzantine-fault-tolerant protocol in which a fixed set of identified nodes takes turns proposing blocks and collectively signs each one before it is accepted. There is no probabilistic settlement and no reorganization window: once a block carries a quorum of signatures, it is final. At AERE's cadence, that happens every 0.5 seconds.

As an operator, your node:

Proposes blocks
Takes its turn in the round-robin proposer rotation, assembling and broadcasting candidate blocks.
Signs every block
Participates in the prepare/commit rounds that give each block its quorum — ⌈(2N+1)/3⌉ signatures — and its instant finality.
Holds the line
Maintains a full copy of the chain, serves peers, and stays online. Liveness is the whole job: the network's fault tolerance is built from operators who stay up.
Votes on membership
Adding or removing a node requires a majority vote of the existing operator set, recorded on-chain. Once you are in, you are part of the network's governance, not a customer of it.

Protocol documentation calls these nodes validators. There is no token-stake bond and no stake-based selection in the current phase — membership is by identity and vote, which is why we select operators the way we do (below).

Hardware requirements

A verification node is a single Hyperledger Besu instance. The requirements are modest by design — the point of this program is operator diversity, not exotic hardware.

ComponentMinimumRecommended
CPU4 vCPU (x86-64)8 vCPU, dedicated cores
Memory16 GB RAM32 GB RAM
Storage500 GB NVMe SSD1 TB NVMe SSD (headroom for growth)
Network100 Mbps, static public IP1 Gbps, static public IP
OSLinux (Ubuntu 22.04/24.04 LTS or equivalent), Java 21 or the official Besu container image
OperationsYour own infrastructure or your own cloud account — not Foundation-provisioned. Monitoring with alerting. A reachable on-call contact.

Sub-second blocks reward low, stable latency: prefer European or otherwise well-peered locations and avoid heavily oversubscribed instances. Full technical setup is covered in the onboarding runbook you receive when accepted.

The operator grant

Accepted operators receive an operator grant of 2,500 to 5,000 AERE, funded from the on-chain Ecosystem Reserve, structured around a 90-day shadow run:

On shadow start
2,500 AERE
Paid when your node is fully synced, monitored, and begins the 90-day shadow run alongside the live set.
On completion
up to 2,500 AERE
Paid at the end of the shadow run, scaled to measured uptime against the 99.5% target.
Then
Vote-in
Operators who complete the shadow run are proposed to the live verification set by on-chain vote.

The grant is the only committed compensation today. A protocol-level fee share for verification node operators is under design and will be announced when — and only when — it is live. We do not promise yield we have not shipped.

Who we select

Because QBFT membership is identity-based, the value of the set comes from who is in it. We select for verifiable independence, not for volume of applications.

CriterionWhat it means in practice
Named entityA registered organization — company, university lab, foundation, or cooperative — not an anonymous individual. The entity name is published on this site.
Public identityYou are willing to be publicly listed as an AERE node operator, with a named technical contact.
Independent infrastructureYour own servers or your own cloud account, in a data center / provider that meaningfully differs from the existing set. We actively select for provider, network, and jurisdiction diversity.
Operational track recordEvidence you run production infrastructure today — other chains, RPC services, hosting, research clusters. We verify.
99.5% uptime targetMeasured monthly over the shadow run and as a standing expectation in the live set, with coordinated maintenance windows.

The road from 3 to 21

Fault tolerance in QBFT is arithmetic, not marketing: a set of N nodes tolerates f = ⌊(N−1)/3⌋ faulty nodes. We publish the math because it is the honest measure of where the network stands.

Today
3 nodes · f = 0
  • All three operated by the Foundation
  • One node failure pauses block production
  • Program open — first external cohort in onboarding
Phase 1 · target within 2026
7 nodes · f = 2
  • 4+ independent external operators, publicly named
  • Foundation becomes a minority of the set
  • Two simultaneous failures survivable
Phase 2 · the following 18–24 months
21 nodes · f = 6
  • Multi-jurisdiction, multi-provider operator set
  • Foundation nodes reduced toward parity with any single operator
  • Operator fee share live (once shipped, not before)

Nodes are added one at a time by on-chain majority vote of the existing set, each addition recalculating the quorum. Every membership change is publicly verifiable on the live consensus page.

Apply to operate

One email. No forms, no waitlist theater. Send the following to [email protected]:

  2. What you run today — your current production infrastructure: chains validated, services hosted, or research systems operated.
  3. Where the node would live — provider, data center location, and whether the hardware meets the requirements above.
  4. Why AERE — two sentences are enough.

Straight answers

Is there slashing?

No. QBFT has no protocol-level slashing — there is no bonded stake, and nothing is burned for downtime or misbehavior. What exists instead is removal: a majority of the operator set can vote a node out, on-chain, and the grounds for that are written down and shared with every operator before they join. We state this plainly because operators deserve to know exactly what mechanism governs them.

Do I need to buy or stake AERE to participate?

No. Membership in the verification set is by identity and vote, not by stake. The program pays you — the operator grant — rather than the other way around.

What does the Foundation control after I join?

Not your node, not your keys, not your infrastructure. The Foundation operates its own nodes and holds the same one-vote-per-node membership rights you do. The explicit goal of this program is to make the Foundation a minority of the set.

What happens during the 90-day shadow run?

Your node runs fully synced alongside the live set, with uptime and signing-readiness monitored, before it is voted into consensus. It is a rehearsal with real measurements — so that by the time your node helps finalize blocks, both sides know it belongs there.
