One family of blockchains, running live.
The Twin Blockchain is a family of four coin chains — TWOPI, KEEL, AGORA and TESSERA — tied together by one hub, built for people first: not an exchange, and not a billboard for other people's coins, but a public home where ultimately anyone can hold a blockchain of their own. The family produces blocks around the clock, and this page shows it as it is: how tall each chain stands, when its newest block landed, and how the family is joined together. No account, no sign-up — looking is free, and the door is open.

In short — the first ten seconds
Four coin chains (TWOPI, KEEL, AGORA, TESSERA) and one hub, producing blocks live. This site publishes their own records about every five minutes so anyone can check heights, supplies and blocks — no account, no sale, no price. What the family charges, and what is free, is stated plainly on the fees page. The hub carries a coin of its own — HUB, fixed at 1,000,000,000 when it was created — and it is the chain that ties the four together.

How fresh is this data?
Every number on this page comes from the chains' own published records, refreshed about every five minutes. The line at the top of the page always says when the data was updated. If an update is ever late, that line turns into a plain warning and the numbers are shown as the last ones published — never dressed up as live. The glossary explains what stale means on this site.
The family right now

What the coloured dots mean
Green — the chain is producing and its published record was updated recently. Amber — the chain's last published record is older than usual; the numbers shown are the last ones published, with their times. Red — the chain is not publishing right now. The dot never guesses: it is read from the chain's own publication time.
Joined as one combination
The four chains are not four separate projects. Each coin chain is anchored to the family's hub: a fingerprint of the coin chain is written into the hub, where anyone can check it later. The combination was verified end to end on October 25, 2026, and the anchors of record are:
- KEEL block 2,212 is anchored on the hub at block 12,224 — anchor transaction 7e08562dcb966671f89a601f86c946346895fd7e42d91f2997366a90fc982ebc
- AGORA block 2,198 is anchored on the hub at block 12,222 — anchor transaction f9e5cb1755538a02b8775c560935bf9ad0f4f39b39a0109c3ea9749ad39072f7
- TESSERA block 1,980 is anchored on the hub at block 12,225 — anchor transaction 804120b060bc1714d0e776b3da12d9d47d8f03792c201ab741d83101
- TWOPI is the chain the combination was submitted from: its validator signed and sent the three anchors above to the hub on October 25, 2026.
Anchoring is how the family proves its chains belong together and have not been quietly rewritten.
For people, first
Twin was not built to be another exchange, and it is not a marketing platform for other people's coins. It is a public blockchain for people: open on the same terms to giant corporations and to individual miners and builders, to small businesses and to families. If holding it in one pair of hands would keep another person from building on it, then it does not need those hands — the platform belongs to the people who use it. The platform is not free to run on: fees power it, the way they do on Ethereum and Bitcoin, and the questions & answers say plainly what that means.
The point: a blockchain of your own
Personal blockchains
The whole point of Twin: ultimately, anyone will be able to create their own personalized blockchain and put it on this family — hosted here, with security kept throughout. One chain for one person, one business, or one family. The tools for that are a building program, not a finished door; this site will say plainly when they open. The joining terms summary and the fees page already state the shape and the proposed costs.
Join the family — Fusion
Other blockchains and projects join Twin through Fusion: access to joining, on attestation terms. A joining chain shows what it is and agrees to the family's terms — and then it belongs. Fusion is a way in, not a wall. Its record format and badge criteria are published on the attestation page.
The wallet is the discovery surface
The Twin wallet is where people find crypto and blockchain organizations, and where trader-facing tools live as they are lawfully built and opened.
Look around
The coins
Each coin has its own page: what it is, how much of it exists — the amounts are fixed and can never grow — who holds the founding accounts, and how to read its live numbers.
The explorer
Browse the newest blocks on every chain, or search for any block by its number or its fingerprint (hash). Every block ever produced is in the published record.
Try it now: look up block 3,941 — the explorer opens with the search already run.
Honest limits
This site is for looking. The coins are not for sale, they have no market price, and nothing here is an offer or a promise. There is no buying, selling or staking on this site — anyone who tells you otherwise is not us.
If a number or a word on this site looks wrong, the about page carries a corrections path — a correction from a reader is a gift.
The words, plainly
Every blockchain word this site uses — block, anchor, attestation, severance, checkpoints, the test and main networks, and the rest — explained in ordinary English, no prior knowledge assumed.
Questions, answered
What Twin is and is not, what it costs and why, what a personal blockchain is, and how other chains join — the questions strangers ask most, answered plainly.
What it costs, and joining
What Twin charges, in the open — the one fee in force today and every proposed figure labelled proposed — and the joining terms in plain language: the same door, on the same terms, for everyone.
