Why it exists

Today, someone else can freeze your account and decide who you are online.

Web4 changes that: a decentralized internet where you control your identity and your money. Core Blockchain (XCB) is the public blockchain it runs on.

Today → On Core

The same things you do today.
Now you’re in charge.

Prove · CorePass

Show you’re verified without handing over a copy.

TodayEvery new service wants its own copy of your passport, stored on its own servers.

On CoreYou verify once. Services ask, you approve, and your documents stay encrypted on your phone.

Pay · CorePay

Pay someone in seconds.

TodayA card payment passes through several companies, and any of them can hold or decline it.

On CoreA payment link sends you straight to the provider, today Ping Exchange, and you approve it in CorePass. No card network in between.

Payment links live since June 2026How payments work

Trade · Ping Exchange

Trade with verified people.

TodayOn big exchanges, you often trade against a market maker — a firm that sits on the other side and helps set the price.

On CorePing is a hybrid exchange where everyone on the other side is a verified person. For XCB and CTN (Core’s coin and token) there is no market maker, so the price is whatever buyers and sellers agree on. Supervised under Swiss anti-money-laundering rules (SO‑FIT).

Daniel and Lars. On record since 2022.

We’ve explained Core as the official community channel, endorsed by CoDeTech’s founders. Nobody at CoDeTech signs off on what we publish. No VC, no payroll: just the two of us and a camera.

“They took the time to understand Core, explain it properly, support the community, and help people see the bigger picture of what we are building. That kind of dedication is rare, and it deserves recognition.”
