Testnet live (4)

  • Celestia

    status: liveTestnet live

    Modular data availability network. Mocha-5 replaced mocha-4 in a hardspoon and starts at height 1; a light node samples the DA layer on 500 MB of RAM and one core.

    Hardware: 1 vCPU · 0.5 GB RAM · 20 GB ssd — Project published sizing for a non-archival light node: 500 MB RAM, single core, 20 GB SSD, 56 Kbps. An archival light node is sized separately at 7 TiB. (source)

  • GenLayer

    status: liveTestnet live

    Adjudication layer where AI validators settle contracts that need judgement. Testnet Asimov is live on chain 4221; validator mode requires a 42,000 GEN stake.

    Permissioned. Participation is permissioned: the linked validator setup requires a token stake, documented at that link. There is no separate open, unstaked way to run this testnet today.

    Project site (builders)Validator setup guide (permissioned)

    Hardware: 8 vCPU · 16 GB RAM · 128 GB ssd — Documented validator requirement for Testnet Asimov: 8 cores/16 threads, AMD64 only (ARM64 unsupported), 64-bit Linux, Docker and Python 3, 100 Mbps. Storage is the documented SSD/NVMe minimum. (source)

    Incentive signals

    • Project docs state that forwarding node metrics to the Foundation dashboard "may positively influence testnet points/rewards (visible healthy nodes are prioritized)". No reward is described for simply running a node. (project statement, seen ) (source)

  • Canopy

    status: liveTestnet live

    Layerless appchain framework: sovereign L1s launched from templates on a shared root chain. Public testnet running, with node docs sized for a small VPS.

    WebsiteTestnet portal

    Hardware: 2 vCPU · 4 GB RAM · 25 GB disk — Documented minimum for a basic validator. The same page recommends 4 vCPU / 8 GB / 100 GB, and 8 vCPU / 16 GB / 200 GB with the monitoring stack, on Ubuntu 26.04 LTS. (source)

    Incentive signals

    • Project docs let a participant record testnet campaign points "for possible consideration in a future CNPY distribution", and state that submitting them confirms no eligibility, allocation, token value or date. (project statement, seen ) (source)

  • Pharos Network

    status: liveTestnet live

    Modular parallel L1. Its Atlantic testnet answered eth_chainId with 688689 when we checked, matching the docs. The published validator spec is data-centre class.

    Hardware: 32 vCPU · 256 GB RAM · 5000 GB ssd — Published validator spec: 32 cores at 2.8GHz or faster, 5 TB SSD at 350MiB/s and 30000 IOPS, 0.5 Gbps network. The docs give no separate, smaller testnet sizing. (source)

    Funding

    • Seed, $8,000,000, announced (source)

Mainnet live (4)

  • Boundless

    status: liveMainnet live

    ZK proving marketplace from RISC Zero. Its July 2025 incentivized testnet is over: the docs list mainnet deployments only, and provers post slashable ZKC collateral on Base mainnet.

    Tracking since:

    WebsiteTestnet portal

    Hardware: 32 GB RAM · 200 GB nvme — Documented prover minimum: 16 CPU threads above 3GHz, 32 GB RAM, 200 GB NVMe, one NVIDIA GPU with 8GB+ VRAM, Ubuntu 24.04. Docs recommend 10+ GPUs to stay competitive. CPU core count is omitted because the docs specify threads, not cores. (source)

    Funding

    • RISC Zero Series A, $40,000,000, announced (source)

    Incentive signals

    • Project docs describe Proof of Verifiable Work: provers may be rewarded in ZKC for proving work, and must stake ZKC before any work they submit becomes eligible. (project statement, seen ) (source)
    • Project docs state provers lock ZKC as collateral, typically at least ~10x a request maximum fee, and are slashed if a proof is not fulfilled on time - 50% of that collateral is burned. (project statement, seen ) (source)

  • tea Protocol

    status: liveMainnet live

    OP Stack L2 paying open-source maintainers for package contributions. Mainnet chain 6122 answered our eth_chainId check; the tea Sepolia testnet RPC, explorer and faucet no longer resolve.

  • Nexus

    status: liveMainnet live

    Verifiable-compute network built around a zkVM. Its public testnet closed in March 2026; mainnet launched May 20, 2026, so a testnet node guide is no longer this project's guide target.

    • Series A, $25,000,000, announced (source)

  • Stable

    status: liveMainnet live

    Payments L1 that uses USDT as its gas asset. Its public testnet was the original guide target, but mainnet (chain 988) has been live in production since December 8, 2025.

Watching (1)

  • Ritual

    status: endingWatching

    L1 with AI-inference precompiles for onchain agents. Docs describe a live testnet (chain 1979), but its RPC, explorer and faucet hosts did not serve when we checked.
