// the evidence
Claims, and where each one stands.
Every claim on this page carries its evidence tier. Nothing is smoothed over, and nothing a project told me is presented as something I checked.
Canton Nodes presents professional RPC and API services for Canton, including public API endpoints and dedicated RPC plans.
cantonnodes.com homepageThe homepage under Public API for the Community says free access to Canton for developers, labels Canton Mainnet Live, and shows the production endpoint https://api.cantonnodes.com.
cantonnodes.com homepageDedicated RPC Solutions lists Experiment at $0 on the public API, and Prototype at $899 a month, with the stated request caps and support levels on that page.
cantonnodes.com homepageThe footer says Canton Nodes is professional blockchain infrastructure for Canton, powered by Proof Group, and describes Proof Group as an investment firm and Super Validator on Canton.
cantonnodes.com homepageCanton Nodes API publishes a Scan API Documentation page at api.cantonnodes.com/docs, served as Swagger UI against /docs/openapi.yaml. That OpenAPI document is versioned 0.0.1, with its title field set to Scan API.
api.cantonnodes.com/docs and openapi.yamlGET https://api.cantonnodes.com/v0/round-of-latest-data answers on the homepage Quick Start path. That is not a measured uptime percentage.
api.cantonnodes.com/v0/round-of-latest-dataGET /v0/dso and GET /v0/scans return network data that includes Proof-Group-1 among named Super Validator scan endpoints, alongside Digital-Asset-1, Digital-Asset-2, and Global-Synchronizer-Foundation.
api.cantonnodes.com/v0/dso and /v0/scansproofgroup.xyz describes Proof Group as partnering with builders, and says it was founded by Noah Jessop after he sold Honeyminer to Core Scientific.
proofgroup.xyz// what would move the score
Catalysts.
Each one names what I am watching and what would prove me wrong.
api.cantonnodes.com still answers the documented Scan API paths.
Falsified if: the public endpoint stops resolving, or the homepage drops the Canton Mainnet Live label.
The homepage still says the product is powered by Proof Group.
Falsified if: that attribution is removed without a dated replacement.
// what I could not verify
Gaps.
These are findings, not omissions. I looked and state what I found.
Not a Super Validator election claim for Canton Nodes API. The homepage attributes Super Validator status to Proof Group, which powers the product. Live /v0/scans output listed Proof-Group-1 among SV scan endpoints. This page does not treat Canton Nodes API itself as an elected Super Validator.
No press email on cantonnodes.com. The homepage contact section is a form and exposed no mailto address.
Platform-wide AUM or stake figures. Neither cantonnodes.com nor proofgroup.xyz published Canton-scoped AUM, stake, or node-count figures. Homepage RPC plan prices and request caps are product terms, not AUM.
About, terms, and press pages absent. HEAD checks for /about, /terms, /privacy, /press, and /blog on cantonnodes.com returned 404. Ownership signals rest on the homepage and Proof Group site.
// open to the project
Sections Canton Nodes API can fill.
These stay empty until the project supplies them. Anything supplied is labeled as supplied, dated, and never rendered as something I verified. Declining changes nothing else on this page.

Published usage with a methodology, so a count can move off announced tier.
// conflicts
Position.
Position disclosure. I hold $CC and $CNTN. This page covers a Canton-native product, which triggers disclosure under my map. Canton Nodes API itself is not a holding of mine. The full conflicts register is on the disclosure page. Canton Nodes API has no commercial relationship with Canton Catalyst, and nothing here was requested, reviewed or paid for.
