Sigma Node (presented in corporate releases as Sigma Node Technologies / Sigma Node Network) sells a tidy story: spare device capacity and internet traffic feed a distributed artificial-intelligence infrastructure, rewards arrive in a Sigma token, and “proof of contribution” sounds suitably technical. A June 2026 press release still spoke in the future tense about preparing to launch. That is a short history for anyone asking you to buy hardware, licences or “nodes” today.
A quick check finds marketing, not audited customers. Syndication of an ACCESS Newswire release onto finance aggregators is not the same as investigative coverage. Telegram growth and quest platforms that pay for follows are normal Web3 launch noise; they do not prove AI companies are buying the bandwidth. Public materials naming a Dallas contact do not, on their own, show that every local promoter is an officer of the company.
Promoters — including names circulated in regional chats — should be treated as independent salespeople until the firm itself confirms them. The dangerous shape is familiar: buy a node, earn tokens, earn more if you stack nodes, earn more still if friends buy. If the cash for withdrawals mainly comes from new node buyers rather than external AI demand, you are looking at a recruitment economy wearing a compute costume. We are not calling Sigma Node a proven fraud in court; we are saying the transparency is too thin for a deposit.
Ask for contracts with bandwidth buyers, audited revenue, withdrawal rules in fiat or major coins, and a registerable company you can verify. If the answer is another Telegram invite, keep your money.
