General

What is the Twin Blockchain?

Twin is a public blockchain family of five chains: four coin chains — TWOPI, KEEL, AGORA and TESSERA — and the Hub, the chain that anchors them together. The family is live and producing blocks around the clock, and this website publishes the chains' own records about every five minutes so anyone can check them.

Is Twin a crypto exchange? Can I buy or trade coins here?

No. Twin is not a crypto exchange, and it is not a marketing platform for other people's coins. This website is for looking: nothing here is for sale, the coins carry no market price on this site, and there is no buying, selling or staking here. Anyone who tells you otherwise is not us.

Who is Twin for?

People, first. Twin is open on the same terms to everyone: giant corporations and individual miners and builders, people, small businesses and families alike. The same door, the same terms, for all of them.

What is the difference between a coin and its chain?

The chain is the running record — the ledger of blocks. The coin is the unit that chain's accounts hold: TWOPI is the coin, and the TWOPI chain is the record that keeps it. In this family each chain carries one coin — the four coin chains carry TWOPI, KEEL, AGORA and TESSERA, and the Hub carries HUB.

What does the Hub do?

The Hub is the family's anchor chain, and it carries a coin of its own: HUB, fixed at 1,000,000,000 when the chain was created, with no more ever to be made. Its network vault pays out 2 HUB with each block as transfers, so the total only ever moves between accounts — it never grows. A fingerprint of each coin chain is written into the Hub — anchored — where anyone can check it later. That is how the family proves its chains belong together and have not been quietly rewritten. Like every coin in this family, HUB is not for sale here and carries no market price on this site.

Money & fees

Is Twin free to use?

No — the platform is not free, and that is deliberate: the fees are what power the platform itself, the same way fees work on Ethereum and Bitcoin. On the core chains, fees burn 100% — they are destroyed, not collected by anyone. The service layer around the chains — creating and publishing a personal blockchain, hosting, and platform services — is what carries the platform's revenue. The exact fee schedule has not been published yet; when it is settled, it will be published here, in the open. The proposed schedule — every figure labelled proposed, none in force — stands on the fees page.

What is the difference between the test network and the main network?

The test network is the practice ground: a pilot chain starts there so it can be proven while nothing real is at stake. The main network is the live record — a chain created there joins the family's published record. The fees page lists the proposed one-time figure for each, both labelled proposed and neither in force.

What is a base unit?

The smallest piece of a coin: one coin is 1,000,000 base units. Fees are counted in base units so a fee can be stated exactly even when it is a tiny fraction of a coin — the family's core-chain fee is 1 base unit per transaction, and 100% of it is burned.

Is anything on Twin fee-free?

Only two things: donations, and the Citizens Wealth Organization. Everything else the platform provides carries fees.

What is the Citizens Wealth Organization?

A separate organization from Twin itself — not a part of Twin and not a part of this website. Alongside donations, it is the one standing exception to platform fees. It is currently parked: not active, and nothing about it is offered here.

Your own blockchain, and joining

What is a personal blockchain?

It is the whole point of Twin. Ultimately, anyone will be able to create their own personalized blockchain and put it on Twin — hosted by the family, with security kept throughout: one chain for one person, a small business, or a family. The tools for creating a personal blockchain are a building program, not a finished door — when they open, this site will say so plainly. The shape of the terms is already published as a plain-language joining terms summary, with the attestation and badge standards beside it.

What does anchoring prove — and what does it not prove?

An anchor proves three things: that a chain's history was not quietly rewritten after the anchor point (tamper-evidence), the order its checkpoints stand in, and that the chain is alive and reporting — a public heartbeat. It does not prove more than that: anchoring does not give a chain the Hub's security, does not make its transactions safe, and is not an endorsement. The attestation page states the same limits for the verified badge.

What is a checkpoint?

A written record of a hosted chain’s state at a moment, anchored into the Hub. A checkpoint gives the chain tamper-evidence — a later rewrite of its history would show against it — proof of the order its checkpoints stand in, and a public heartbeat: evidence the chain is alive and reporting. Checkpoints, once anchored, are never removed, even after a severance — and a checkpoint does not give a chain the Hub’s security.

What is Fusion?

Fusion is Twin's door for joining. It is how other blockchains and projects get access to join the Twin ecosystem — on attestation terms: a joining chain shows what it is, agrees to the family's terms, and then it belongs. Fusion is a way in, not a wall.

What is the Twin wallet for?

The wallet is Twin's discovery surface: the place where people find crypto and blockchain organizations, and where trader-facing tools live as they are lawfully built and opened.

Does Twin ever hold my coins or my keys?

No. Twin is fully non-custodial: your keys and your coins stay in your own wallet, and only you can move them. That is also why lost keys mean a lost chain — no one at Twin can recover them. The joining terms summary sets this out in full.

What happens if I lose my keys or my seed phrase?

The chain is lost — plainly, and by design. Twin is non-custodial: it never holds your keys or your seed phrase, so no one at Twin can restore them or sign in your place. That is why the joining terms summary teaches the seed phrase before publishing, in plain words: keep it private, keep it offline, and keep a copy somewhere safe.

Can I take my blockchain away from Twin?

Yes — joining is not a lock-in. As the joining terms summary states, severance is de-listing and de-anchoring only: a severed chain keeps existing, and before a severance for cause takes effect you get notice and a guaranteed export window — 30 days at minimum — to take a complete copy of your chain's data with you. Your data and your keys are never deleted by Twin.

What happens if my chain is severed?

Severance is de-listing and de-anchoring only, as the joining terms summary states: Twin removes the chain from its registry, wallet and explorer surfaces and stops anchoring it — and that is all. There is no pause button and no kill switch: the chain keeps existing for anyone who runs its nodes. Before a severance for cause takes effect you get notice and the guaranteed export window — 30 days at minimum — and your data and keys are never deleted. For sanctions or illegality, de-anchoring is immediate and the notice comes after; the export window still stands.

Can I start my own blockchain on Twin today?

Not yet — and this site will not pretend otherwise. The tools for creating your own personalized blockchain are a building program, not a finished door. What already stands published is the shape of it: the joining terms summary, the fees page with its proposed figures labelled proposed, and the attestation page. When the door opens, it will be announced here first.

Launches & this website

When did TWOPI launch?

TWOPI, the family's first coin, launched on October 22, 2026. Each coin's own page — TWOPI, KEEL, AGORA, TESSERA — shows what it is, how much of it exists, and its live numbers.

How do I read a coin page?

From the top: the live panel shows the chain's height — how many blocks it has produced — and its newest block. Below it, the fixed-supply table states how much of the coin exists in whole numbers, the founding accounts show their live balances, and the anchor is explained in words. Every figure on the page comes from the chain's own published record, and the page shows when that record was published.

Where do the numbers on this website come from?

From the chains themselves. Each chain writes its own records as it runs — never anything private, never any keys — and this site publishes those records about every five minutes. Every page shows when its data was published; if an update is ever late, the page says so plainly and shows the last published numbers with their times. Nothing here is filled in or guessed.

Why does the site sometimes say its data is stale?

Because an update was late, and the site would rather say so than dress old numbers up as live. The chains' records are refreshed about every five minutes; when a refresh is late, the line at the top of the page turns into a plain warning and the last published numbers are shown with their times. The glossary explains what stale means on this site.

I spotted an error on this site. What do I do?

Tell us — a correction from a reader is a gift. The about page carries the corrections path: say which page and what looks wrong. Corrections are made at the source file, re-verified on the live page, and noted in the site's improvements log.
