The House: a guide to KXCO's new product names

On 9 October 2026 KXCO brought its products into one family of seven and gave the family a name: the House. Most of the products changed their names on the same day. Sentinel became Portcullis, Treasury became Sovereign, Meridian became Guildhall, and the names that stayed, Round Table and Armature, took their places in a structure that now has one centre, four commercial lines and two foundations. This guide explains what each name means, where every former name went, what changed for developers, and what did not. The short version is on the knowledge base at The House and Former names. This is the long version.

What changed on 9 October 2026

Seven products now sit under one family name, KXCO by Knightsbridge, and nothing else is a product name. Each product's old address redirects to its new page: kxco.ai/sentinel goes to Portcullis, kxco.ai/treasury to Sovereign, kxco.ai/meridian and kxco.ai/nexus to Guildhall, and kxco.ai/sovereign-ai to Round Table. Package names, routes in code and other technical identifiers keep their spelling, per Former names. The free scan is still kxco-pq-scan, the chain is still chain ID 1111111, and the explorer is still at chain.kxco.ai.

Why a House, and why seven

KXCO's proposition is that two parties with no reason to trust each other can each check the same record against a standard both can inspect. The bridge in the Knightsbridge name stands for that crossing, and the House stands beside it. Each product is named for a room or office that a medieval or Renaissance household relied on: the council, the gate, the herald, the coin, the hall, the trading league and the frame that holds the building up, per The House.

Seven is the cap. A product earns its own name only when it has its own buyer and price list. Everything else is a module inside one of the seven, written as the product name and a plain word, such as Portcullis Survey, and a module never carries a mark or logo of its own, per Writing about KXCO. An offer is the product name and a lower-case descriptor, such as Sovereign for institutions, and a descriptor is not a sub-brand. One masterbrand carries the reputation, product names tell the reader which product is meant, and module names say what each part does.

The arrangement follows the money. The centre, Round Table, holds the shared data model and the record of sourced claims kept in it. The four commercial lines, Portcullis, Sovereign, Guildhall and Hanse, are what institutions buy, and each has its own buyer, budget and price list. The two foundations, Herald and Armature, are sold directly to developers and identity teams and reach institutions through the four lines.

The seven, room by room

KXCO Round Table, the council

In the Arthurian legend the table was made round so that no knight sat at its head, per Britannica. Every seat carried the same standing, and what the council agreed was held in common. That is the job the product does. Round Table keeps the shared data model at the centre of the House, the ontology, which is a data model and not an AI model. It keeps claims about organisations, people, assets and events as a structured record. Every claim carries its source, the basis for it, a confidence level and the date it took effect, so a reviewer can see which claims applied on a given date and how they changed afterwards. Analysts and AI models work from the same record, and the record shows which of them said what.

Its modules are Round Table Ontology, Round Table Live map and Round Table Review. Its status is live, in private deployments, and public maps use public data only, per its page. Where it stops: Round Table records and explains. Decisions stay with named people, and confidential institutional graphs never appear in marketing. Two former names fold into it. KXCO Sovereign AI is now Round Table, private deployment, which removed a clash with the Sovereign product. The AI Sector Ontology at kxco.ai/ontology-live is now the Round Table Live map.

KXCO Portcullis, the gate

The portcullis is the iron lattice gate of a castle gatehouse, lowered in grooves cut into the stone, per Britannica. With the gate down, the guard could see and question whoever stood outside before anything was let through. Portcullis brings KXCO's security work into one product. It finds quantum-vulnerable cryptography across an estate. It is designed to record the fix with a re-scan showing that the finding is no longer detected, and to hold back releases that do not meet policy. It also assesses AI agents before they are trusted with work.

Its modules are Portcullis Survey, Portcullis Fortify, Portcullis Hold and Portcullis Muster. Its status is live in parts: the quantum readiness scan, the scoring of an agent's declared posture and the free kxco-pq-scan are live, per its page. Where it stops: a release signature establishes provenance and does not prove the software is secure, and the free scan covers JavaScript dependencies only. Portcullis gathers the most former names. Sentinel AI and KXCO Sentinel became Portcullis, because Sentinel clashed with Microsoft Sentinel. The Bastion scan engine became Portcullis Survey, and its engine identifiers keep their spelling. PQC Host became Portcullis Hold. Agent Certainty and Agent Trust Analysis became Portcullis Muster, which is always described as scoring declared posture, not runtime behaviour.

KXCO Herald, the herald

Medieval heralds carried messages between parties, announced who was who and kept the rolls of arms that proved identity on sight. The English heralds were incorporated as the College of Arms in 1484, per the College of Arms. Herald issues identities, lets their holders sign, lets any other party verify, and revokes an identity when circumstances change. A valid signature shows that the holder of a given key signed the content and that it has not changed since.

Its modules are Herald Issue, Herald Sign and Herald Verify. Its status is live for domains and documents, and identity for people and AI agents is in development, per its page. Where it stops: authority to act is a separate check from a valid signature. Its former name was KXCO Verified, at verify.kxco.ai, and the word was retired on purpose: a checkmark says a platform vouches for you, and a Herald signature shows you signed.

KXCO Sovereign, the coin

The gold sovereign was first struck in 1489 for Henry VII, per Wikipedia. Its weight and fineness were set by rule, so its value rested on a standard any merchant could check. Sovereign is the software institutions use to hold, exchange and settle value under common rules. Through its software and institutional model it covers FX, securities, futures, options, bonds, tokens, stablecoins and cash. Licensed institutions hold the customer assets and the regulated relationships. KXCO supplies the software and holds no customer assets.

Its modules are Sovereign Exchange, Sovereign Settlement, Sovereign Self-custody and Sovereign for institutions. Its status is live, per its page. Where it stops: KXCO is the software provider, and the institution and its partners own the regulated service, permissions and availability. Its former name was KXCO Treasury. KnightsPurse, the wallet at purse.kxco.ai, became Sovereign self-custody, a module and not a wallet brand.

KXCO Guildhall, the hall

A guildhall was where a guild's members met to admit newcomers, settle disputes and keep their records. The Guildhall of the City of London was built between 1411 and 1440 and still stands, per Wikipedia. Guildhall gives a Member a controlled room for a transaction. The Member owns the room. Guests are admitted on scoped tickets that expire, and they read watermarked, timestamped reader copies. AI prepares the material and checks the record. A named person controls the deal and approves it.

Its page lists the modules that are live today: rooms, scoped tickets, non-disclosure agreements signed at the door, reader copies, document versions, redaction with a person approving each term, human approval of Members and offerings, electronic signature with certificates, an AI assistant that cites its pages, Relationships, vehicles, cap tables, capital calls and bank reconciliation, per its page. Where it stops: Guildhall is software for running a deal. It is not an invitation to invest and does not replace the institution's own governance. Its former names were KXCO Meridian and Nexus, and Meridian was retired because it carried clash risk. The Round Table upgrade once offered on the Meridian page is now Guildhall Round Table Review.

KXCO Hanse, the trading league

The Hanseatic League was a confederation of merchant guilds and market towns that traded across the North Sea and the Baltic from the thirteenth to the seventeenth century, with offices in London, Bruges, Bergen and Novgorod, per Britannica. Hanse is the cross-border line. It is software that connects fiat and stablecoin movement across markets through licensed financial partners, with identified senders and receivers and a shared record of each movement. The partners deliver the financial services. Hanse gives them the common workflow.

Its modules are Hanse Ramp, Hanse Remit and Hanse Accounts. Its status is in development, and no launch date is set, per its page. Where it stops: partners, jurisdictions and availability need confirmation before any customer commitment. Its former name was OneWorld, which was listed on the Treasury page as in build. It is written Hanse, not Hansa.

KXCO Armature, the supporting frame

An armature is the iron framework that holds a structure together from within. In Gothic cathedrals, armature bars carried the weight of the stained glass so a window could span an opening no single pane could, per Wikipedia. Armature is the layer-one network, a base blockchain and not one built on another chain, that gives the House its common public record. Attestations from the other products, and settlements where they run on Armature, are anchored on it. A party outside KXCO can check independently that an anchored record existed in that form no later than the time it was anchored. Armature's signatures use ML-DSA-87, the post-quantum signature algorithm specified in NIST FIPS 204, per its page.

Its status is live, with the public explorer at chain.kxco.ai. Where it stops: an anchor shows a record existed in a given form at a given time. It does not make the underlying claim true. Its former names were KXCO Chain and Armature L1. Armature L1 survives in developer documents only. Everywhere else the network is Armature.

Where every former name went

Exhibit 1 draws the move. Twelve former names on the left, the product or module each became in the middle and on the right, and the product each module belongs to.

The same move as a table, from Former names:

KXCO Command is no longer a KXCO product and has no successor. Pieces published before 9 October 2026 keep their text, and each carries a note at the top naming the products as they are called now, with a link to the former names page.

How the seven connect

Each product page carries an "In the House" section that says what it anchors on, what it runs on and who identifies whom. Exhibit 2 draws those lines and nothing else.

Read it from the foundations up. Armature is the public record: Portcullis anchors its attestations on it, Sovereign settles on it, and Hanse is designed to use it for the record. Herald is designed to supply the identity behind each action: the parties in a Guildhall room, the senders and receivers in Hanse, the agents assessed by Muster and the signer of a Portcullis release. Sovereign carries value: Hanse is designed to run on it, and Guildhall can settle through it or through a Member's own custodian. Round Table sits at the centre: findings and attestations from the other products can be read into it as sourced claims, and Guildhall uses Round Table Review on larger transactions. One record then answers two questions, what do we know and how do we know it.

What changed for developers, and what did not

• Addresses. kxco.ai/sentinel, kxco.ai/treasury, kxco.ai/meridian, kxco.ai/nexus and kxco.ai/sovereign-ai return a 301 to the new product pages, read on 14 October 2026. kxco.ai/chain goes to chain.kxco.ai. Update bookmarks and links, and expect the old addresses to keep working.
• Packages. kxco-pq-scan and kxco-post-quantum keep their names on npm. A package is a technical identifier, and identifiers keep their spelling.
• Engines and routes. The Bastion scan engine is Portcullis Survey in copy, and its routes under pqc.kxco.ai keep their spelling.
• The chain. Chain ID 1111111 is unchanged, the explorer is unchanged at chain.kxco.ai, and the signature algorithm on Armature is ML-DSA-87 from FIPS 204. Write Armature L1 in developer documents only.
• Herald. Describe it as live for domains and documents. Identity for people and AI agents is in development, and a document that says otherwise is ahead of the product.
• Portcullis. Describe Muster as scoring an AI agent's declared posture. Portcullis Hold is designed to hold back releases that fail policy; the page lists what is live today.
• Statuses. Copy the status from the product's own page, and never upgrade it. Hanse is in development with no launch date set.

How to write the names

These are the forms KXCO uses itself, from Writing about KXCO, for partners, press and analysts.

• The company is KXCO by Knightsbridge. KXCO leads as the company name and Knightsbridge stands behind it as the endorsement.
• A product takes KXCO at first use, KXCO Portcullis, and the product name alone afterwards.
• A module is the product name and a plain word: Portcullis Survey, Sovereign Settlement, Guildhall Rooms.
• An offer is the product name and a lower-case descriptor: Sovereign for institutions.
• Round Table is two words. Every other product name is one. Hanse, not Hansa. Product names take no full stop.
• An application built on KXCO by another company keeps its own name, followed by "built on KXCO".
• KXCO supplies the software. Licensed institutions hold the assets and the regulated relationships.
• Give every figure its date and source, describe a product in development as in development, and never describe a signature or an anchor as proof that a claim is true.

Frequently asked questions

Is Sentinel gone?

The name is retired. The product is KXCO Portcullis, and the free scan is still kxco-pq-scan. Sentinel clashed with Microsoft Sentinel.

Where did Meridian go?

Meridian and Nexus are KXCO Guildhall. kxco.ai/meridian and kxco.ai/nexus redirect to the Guildhall page. The name was retired because it carried clash risk.

Is KnightsPurse still a product?

No. KnightsPurse became Sovereign self-custody, a module of KXCO Sovereign. It is not a wallet brand.

What is the difference between Armature and Armature L1?

They are the same network. Armature L1 is the form used in developer documents. Everywhere else it is Armature.

Is Herald live for people and AI agents?

Herald is live for domains and documents. Identity for people and AI agents is in development, per the Herald page on 14 October 2026.

Is Hanse available?

Hanse is in development and no launch date is set. Partners, jurisdictions and availability need confirmation before any customer commitment.

Did the chain change?

No. Chain ID 1111111, the explorer at chain.kxco.ai and the ML-DSA-87 signatures are as they were. Only the name on the page changed, from KXCO Chain to Armature.

What happened to KXCO Command?

It is no longer a KXCO product and has no successor.

Will the old addresses keep working?

Yes. Each old address returns a 301 to the new page, read on 14 October 2026.

Where is the authoritative list?

The knowledge base: The House, The seven products, Former names, the Glossary and Writing about KXCO. Each product's own page carries its status today.
