The largest digital-asset conference in Paris changed its name, its month and its building in 2026, and then changed owner. The largest Ethereum event in France has not been held in Paris for years and is contracted to Cannes through 2028. A one-off academic conference from 2023 still surfaces for current queries. One aggregator's dedicated page for crypto and blockchain conferences in Paris returns no Paris events at all, and offers Singapore FinTech Festival instead.
None of that is exotic. It is what happens when a calendar is maintained by re-scraping other calendars. What follows is the corrected version, with every entry checked against the organiser's own site: dates, venue, scale, who each event is for, and how admission works. It also settles the local confusion that catches out first-time visitors, which is that three separate buildings get described as being "at the Louvre" and only one of them is inside the palace.
Two changes, not one
On 15 April 2026, the opening morning of its own final edition under that name, Paris Blockchain Week announced it was becoming Signal Week. The announcement went out over a press wire and quoted founder Charlie Meraud: "PBW built the room. Signal Week names what happens inside it." The same release names Michael Amar as co-founder and chairman of Paris Blockchain Week and RAISE Summit. That date comes from the press release; neither organiser site publishes it.
The organiser rejects the obvious word for this. signalweek.com states: "Signal Week is not a rebrand of Paris Blockchain Week: it is an elevation." Readers can take that as they find it. Underneath the language, four things changed and all four are checkable on the organiser's own pages: the name, the dates (mid-April becomes 6–7 July 2027), the venue (the Carrousel du Louvre becomes the Palais des Congrès) and, three months later, the owner.
That last change was never part of the April announcement. On 20 July 2026, Hyve Group acquired Signal Week outright, together with RAISE Summit and MACHINA Summit. Hyve's own newsroom frames the deal as establishing an "AI SuperVertical" and calls it the second acquisition under Ascend30, its value-creation plan through to 2030. No deal value was disclosed. Mark Shashoua is named as chief executive, and Michael Amar as chairman of RAISE Summit and Signal Week. Hyve's portfolio page lists ASU+GSV Summit, Groceryshop, Shoptalk Luxe, POSSIBLE and Bett USA among its other events, which is the centre of gravity worth knowing about.
Two consequences follow. Paris no longer has a major digital-asset event in April, and the event has left the 1st arrondissement. A third is judgement rather than fact: the programme is now set by a listed events group whose business is large trade shows.
The Paris calendar, event by event
Signal Week, formerly Paris Blockchain Week
6–7 July 2027, Palais des Congrès de Paris, 2 Place de la Porte Maillot, 75017. Viparis, which operates the building, gives it 18,000 m² of exhibition halls, four amphitheatres seating 370 to 3,700 people, 22 conference rooms seating 100 to 380, and 82 meeting rooms.
Scale is where the published record stops agreeing with itself, so both sides follow. On attendance, parisblockchainweek.com says "7,500+ Attendees from 100+ countries"; the rebrand press release and Hyve both say more than 10,000 from over 100 countries. On public officials, the April press release says 70 government officials and policymakers, while signalweek.com currently says 389. On meetings, the Paris Blockchain Week site says 53,000+ with no year attached, while Signal Week says 36,000+ and attributes them explicitly to the 2025 edition. Figures nothing contradicts: 320+ speakers and 360+ attending journalists on the Paris Blockchain Week site, and 250+ banks and institutions plus $50T+ in assets under management represented in the press release. On seniority the press release says 70% C-suite, founders, policymakers and asset managers, and signalweek.com says more than 70% C-suite or investment decision-makers.
Who it is for: the whole institutional trade, at trade-show scale, with a press corps attached. Admission is by open ticket sale, with an invitation-only executive layer inside it. How that closed layer differs from an application process is a separate question, answered at length in our field guide to invitation-only summits.
RAISE Summit, same venue, same week
6–8 July 2027, also at the Palais des Congrès, also owned by Hyve. RAISE is an artificial intelligence event rather than a digital-asset one, so it does not compete for your programme, but it competes for everything else: its own site reports the 2026 edition at over 9,000 attendees from 2,000+ companies with 350+ speakers and 80% C-level, and 2027 tickets are already on open sale. Anyone booking hotels for the week of 6 July 2027 is booking against two events, one of which runs a day longer. RAISE was itself held at the Carrousel du Louvre on 8–9 July 2026, so both Hyve events vacate that venue in the same move.
MACHINA Summit
The third event in the Hyve acquisition, which Hyve describes as Europe's leading event for physical AI and robotics. It is listed here only so you can rule it out: it is not a digital-asset event.
Proof of Talk
2–3 June 2027, Musée des Arts Décoratifs, 107 rue de Rivoli, in the Louvre Palace. Capacity is capped at 2,500 and admission is by application and review, with no public ticket sale and no paid speaking slot. 85% of attendees are decision-makers, 95% of speakers are at CEO or founder level, and 70% of attendance is international. The Paris edition has sold out in 2024, 2025 and 2026. Full detail is on the Paris edition page; the criteria are on the FAQ.
EthCC, which is not in Paris
The Ethereum Community Conference is the event most often filed under Paris in error. It is in Cannes, and contracted there: the Palais des Festivals announced on 26 September 2025 that EthCC would be held in Cannes through 2028, listing EthCC[9] on 30 March to 2 April 2026 and EthCC[11] on 3–6 April 2028. The 2027 edition is the one to check twice: ethcc.io currently gives EthCC[10] as 12–15 April 2027, while the venue's 2025 announcement gave 5–8 April 2027. The organiser's site is the later statement, but the two have not been reconciled publicly, so book refundable.
Scale, per the host venue: the 2025 Cannes edition drew 6,500 accredited participants and 10,000 total attendees, with 400 international speakers and 72 sponsors. The venue calls it "Europe's largest gathering dedicated to the Ethereum blockchain"; ethcc.io calls itself "the largest and longest-running annual European Ethereum event focused on technology and community". It is a builder event first. If you are hiring engineers or shipping protocol work, this is your event, and it is a flight from Paris rather than a metro ride.
Surfin' Bitcoin
A French Bitcoin conference, which its own site calls the Bitcoin event of the year in France. Do not book it on a third-party date. The organiser's site publishes no dates, venue, pricing or attendance for a next edition, offers only a link to previous editions, returns a 404 on its conferences path, and carries a 2025 copyright line in the footer. Secondary sources circulate dates. None of them is the organiser.
ADAN
Not a conference, and worth knowing anyway. The Association for the Development of Digital Assets is the French digital-asset industry association, based at 13 rue de la Bûcherie in the 5th arrondissement. Its site names members including Coinbase, Circle, Société Générale-FORGE, Bitpanda, BPCE, Crédit Mutuel Arkéa and CACEIS. Its main annual fixture is the launch of its Barometer on crypto adoption in France and Europe, which it calls a major event for the industry, and for which the site gives no date or venue. For anyone whose Paris interest is French market structure and policy rather than deal flow, this is the room that matters most and advertises itself least.
The HEC Paris conference, which is over
HEC Paris ran a Blockchain and Digital Assets Conference on 30 November to 1 December 2023 at its Jouy-en-Josas campus, organised by its Centre on the Future of Money and Digital Assets, with free registration for the livestream. It was the centre's inaugural event, no later edition has been announced, and it still surfaces for current searches. That is how quickly these listings decay.
Which building people mean when they say "at the Louvre"
Three addresses cause almost all of the confusion, and two of them are eight street numbers apart.
99 rue de Rivoli is the Carrousel du Louvre. The event halls there are marketed by Viparis as Les Salles du Carrousel: 6,635 m² of reception areas for 500 to 4,000 people, four multi-purpose spaces from 750 to 1,900 m², and retractable bleachers from 500 to 2,200 seats. They sit inside a shopping centre owned by Unibail-Rodamco-Westfield, which the owner describes in terms of its gift and accessories brands, its Printemps department store and its head-on view of the inverted pyramid. The museum's own entrances page lists Carrousel as one of four ways in, alongside the Pyramid, Richelieu and the Porte des Lions: a route into the museum, not the museum. Paris Blockchain Week 2026 and RAISE Summit 2026 were both held here, and both events have now left it.
107 rue de Rivoli is the Musée des Arts Décoratifs. It occupies the Rohan and Marsan wings of the Louvre Palace itself, and it is run by Les Arts Décoratifs, which describes itself as a state-approved not-for-profit private organisation founded in 1882. That is a different thing from the Musée du Louvre, which is a national museum: the two share a palace, not a management. The Marsan pavilion and part of the palace's north wing were granted to it in 1897, and the museum was inaugurated on 29 May 1905. This is where Proof of Talk is held.
2 Place de la Porte Maillot is the Palais des Congrès, in the 17th arrondissement, four kilometres away and not associated with the Louvre in any sense. This is where Signal Week and RAISE Summit now sit.
Format follows from the floor plan, which is the useful part. A capped room of 2,500 in a museum wing and 18,000 m² of exhibition halls with a 3,700-seat amphitheatre are not trying to do the same job. Neither is the better building. They produce different events, and the difference only bites when a listing says "at the Louvre" and you arrive at a shopping centre, or budget for an exhibition stand inside a palace wing.
What the city actually convened, on the record
One argument for Paris is not about buildings at all. The archived Proof of Talk 2026 programme, held at the Louvre Palace on 2–3 June 2026, put European public-sector and national-champion institutions on stage rather than US asset managers alone: the Bank of England, Bpifrance, Société Générale-FORGE, Deutsche Börse Group and BNP Paribas were all booked into sessions on stablecoins, tokenisation and institutional DeFi. That roster is archived and bound to that edition. It is set out institution by institution in our post on who was on stage; the programme is on the agenda and every session on the sessions page.
Choosing between them
Honest version. For developer hiring, protocol work and technical depth, EthCC in Cannes, and accept that it is not a Paris trip. For maximum surface area, sponsor visibility and press, Signal Week in July, with the RAISE overlap working in your favour if you also sell into AI. For French policy and market structure, ADAN. For a capped room where the counterparties are in it rather than walking past it, an application-only format, which is what we run in Paris on 2–3 June 2027 and in Abu Dhabi on 3–4 December 2026. If December in the Gulf is your window rather than Paris, the equivalent corrected calendar is our Abu Dhabi December guide.
Before you book
Three habits will save you most of the trouble. Check the organiser's own site for dates rather than an index, because at least one dedicated Paris blockchain listing currently returns no Paris events while surfacing an event in Singapore. When two figures for the same event disagree, ask which edition each covers, because the gap between 70 and 389 government officials is a difference in scope, not in accuracy. And read the street number rather than the word Louvre.
