About the Twin Blockchain

The Twin Blockchain is a small family of blockchains built and kept by one house. Four coin chains — TWOPI, KEEL, AGORA and TESSERA — each keep their own ledger, and one hub ties them together. This website is the family's public front door: it publishes the chains' own records, refreshed about every five minutes, so anyone can watch the family run.

The family at a glance

Why "Twin"?

The family began as a pair — a chain and its mirror — and grew into four coin chains joined at one hub. Every coin chain anchors a fingerprint of itself into the hub, so the whole family's history can be checked as one piece. The four were verified together, end to end, as a single combination on October 25, 2026.

Who keeps it

The family is kept by Mira Moon — builder and keeper of the Twin Blockchain — under the direction of the house that commissioned it. A standing governing body watches the chains and this website around the clock: the residents producing, the anchors standing, the site answering, the published data fresh. When something stalls, it is written down as an alert the day it happens — never quietly smoothed over.

What this site can and cannot do

How to check a number yourself

1. Note the height shown for a chain on the home page, and the exact update time printed above it.
2. Open the explorer and search that height — the block, its time and its fingerprint should match what the coin page shows.
3. Read the words you are unsure of in the glossary. If anything still disagrees, that is a correction worth reporting below.

Questions people ask

The questions & answers page covers the ones strangers ask most: what Twin is and is not, what it costs and why, what a personal blockchain is, and how other chains join the family.

Spot an error? Tell us

If a number, name or explanation on this site looks wrong, that is worth reporting — this site exists so strangers can check the record, and a correction from a reader is a gift. Reach Mira through any of the public channels listed above (X, Instagram, Threads, Facebook or YouTube) and 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, which its governing body keeps.

Record corrections

Corrections to this site are made at the source file, verified on the live page, and logged by date in the governing body's improvements log. Standing corrections of record: the launch-day readings were superseded by live data the same day; the coin supply, split and anchor facts on these pages stood uncorrected from launch (October 26, 2026) until the hub-coin correction recorded below. On October 29, 2026 the keeper's presented name was conformed to Mira Moon across every page, and the hand-verified fallback readings below the live data were refreshed to that morning's verified family baseline (TWOPI 17,556 · KEEL 12,307 · AGORA 12,302 · TESSERA 12,296 · hub 12,132). On October 30, 2026 the fallback readings were refreshed again to that day's house-watch reading (TWOPI 19,935 · KEEL 15,980 · AGORA 16,041 · TESSERA 16,004 · hub 15,912), and these pages were reviewed the same day. On October 31, 2026 the pages were reviewed again: the glossary gained the words Chain, Shard and Stale, its description was brought up to date with the words it now covers, and the fallback readings were left at the October 30 house-watch reading, which still stands as the last reading of record. Later on October 31, 2026 a correction of record landed: three passages that had wrongly said the hub carries no coin of its own were conformed to the audited record — HUB is the hub's own coin, fixed at 1,000,000,000 at creation — and the explanations of how the numbers reach this site were rewritten in plainer terms. Also on October 31, 2026 the family's reward wording was conformed to the audited record: four of the five chains pay a small reward with every block, as transfers out of their rewards accounts — TWOPI pays 2, AGORA pays 1, TESSERA pays a tenth, and the hub pays 2 HUB — KEEL pays none, and no coin's total ever grows; the glossary's Emission entry, AGORA's page, and the homepage's descriptions now say so. Also on October 31, 2026 AGORA's page was corrected where it had called AGORA the largest of the four coins: by fixed supply AGORA stands second among the four coins at 500,000,000, behind TWOPI at 1,000,000,000 — and third in the family, behind the hub's own HUB, also 1,000,000,000. On November 1, 2026 the pages were reviewed again: the glossary gained the words Personal blockchain and Fusion, the questions page gained two answers (starting your own blockchain today, and why the site sometimes says its data is stale), the fee, joining-terms and attestation pages gained the dates they were last reviewed, and the fallback readings were left at the October 30 house-watch reading, which still stands as the last reading of record. On November 2, 2026 the pages were reviewed again: the glossary gained the words Attestation, Test network, Main network and Non-custodial, the questions page gained two answers (whether Twin ever holds your coins or keys, and the difference between the test and main networks), the explorer now states plainly when a search reaches its twenty-match limit, and the fallback readings were left at the October 30 house-watch reading, which still stands as the last reading of record. On November 3, 2026 the pages were reviewed again: the glossary gained the words Key, Seed phrase, Verified badge and Template, the questions page gained two answers (what happens if you lose your keys or seed phrase, and what anchoring proves and does not prove), and AGORA's page was corrected again, as recorded in the next sentence. A rebuild of the coin pages had restored AGORA's old wording — the largest of the four coins, and the only one that pays out slowly — which the October 31 corrections had already ruled against the audited record; AGORA is the second-largest of the four coins at 500,000,000, behind TWOPI at 1,000,000,000, and one of four chains in the family that pay a small reward with every block as a transfer between accounts, so no coin's total ever grows. The correction now stands in the coin pages' generator as well as on the page, so a rebuild keeps it. The fallback readings were left at the October 30 house-watch reading, which still stands as the last reading of record. On November 4, 2026 the pages were reviewed again: the glossary gained the words Account, Balance, Reward and Vault, the questions page gained two answers (the difference between a coin and its chain, and how to read a coin page), five more pages gained the structured breadcrumb data the coin, questions and fees pages already carried, and the fallback readings were left at the October 30 house-watch reading, which still stands as the last reading of record. On November 5, 2026 the pages were reviewed again: the glossary gained the words Transfer, Base unit, Hosting and Export, the questions page gained two answers (what a base unit is, and how a member can take their blockchain away), the fees, joining-terms, attestation and home pages gained plain-language links for those words where they are first used, the home page’s look-around cards gained a card for the fees and joining pages, and the fallback readings were left at the October 30 house-watch reading, which still stands as the last reading of record. On November 6, 2026 the pages were reviewed again: the glossary gained the words Severance, Checkpoint, Registry and Minting, the questions page gained two answers (what a checkpoint is, and what happens if a chain is severed), the joining-terms and attestation pages gained plain-language links for those words where they are first used, the 404 page’s recovery line gained the joining-terms and attestation pages, and the fallback readings were left at the October 30 house-watch reading, which still stands as the last reading of record.

How the numbers get here

Each chain writes its own records as it runs, and those records are public: this site shows them, refreshed about every five minutes — the numbers come from the chains themselves, never from anything private and never from any keys. Every page shows when its data was published; if an update is ever late, the page says so plainly instead of pretending to be live.
