Traps / False Positives

• Hack The Block 2026 (Paris Blockchain Week): No hackathon - Hack The Block 2026 is fully confirmed (occurred April 11-12, 2026, Luma registration, 10K EUR prize, XRPL track sponsor). However the 2027 successor event -- now rebranded as Signal Week (July 6-7, 2027, Palais des Congres, Paris, acquired by Hyve Group) -- has NO confirmed hackathon component as of August 2026. The official Signal Week site and the TheBlock press release make no mention of Hack the Block continuing. The 2026 hackathon page on parisblockchainweek.com still exists but references 2026 dates only.
• Dutch Blockchain Week 2027: No hackathon - 2026 edition (June 22-28) confirmed and completed. 2027 edition: zero announcements found as of August 2026. Luma calendar shows 0 events. No hackathon registration page on Devpost, DoraHacks, or TAIKAI. The only confirmed hackathon component is "Block and Order: AI-Agents for Compliance" (side event organized by UvA + AI4FinTech in 2025; referenced but unconfirmed for 2026). No bounty-sponsor track found.
• HackMoney 2026: No hackathon - HackMoney 2026 ran Jan 30 - Feb 11, 2026 (confirmed on ethglobal.com). It is a PAST event. No HackMoney 2027 announcement found on ethglobal.com/events, via web search, or on ETHGlobal X/Twitter as of Aug 19 2026. ETHGlobal historically runs HackMoney in Q1 (2020, 2021, 2022, 2026 editions confirmed) so a 2027 edition is plausible in Jan-Feb 2027, but unannounced. Next confirmed ETHGlobal online hackathon: ETHOnline 2026 (Sept 4-16, 2026) -- different focus (general Web3, not DeFi-specific).
• ETHGlobal New York 2026: No hackathon - ETHGlobal NY 2026 ran June 12-14 at Metropolitan Pavilion, New York. Confirmed past event with $175K-$225K in prizes across 15+ sponsors. Application deadline was June 10, 2026. ETHGlobal New York 2027 has NOT been announced -- forkoff.xyz confirms "ETHGlobal has not yet published ETHNYC 2027 dates" as of research date (August 2026). The 2027 edition is a strong historical probability (ETHGlobal has held NYC annually) but no official announcement, dates, or registration page exists yet.
• The Bucharest Hackathon: No hackathon - The Luma event page (luma.com/pwtt2fhh) shows the event is a past/closed event. The official site still promotes the 2026 (3rd edition) without any 2027 announcement. Previous editions: 2023 (1st), 2024 (2nd), 2026 (3rd) - all April. No 2027 edition announced as of August 2026. The "previous editions" page says "Be Part of the 2026 Story" with no forward-looking 2027 content.
• Istanbul Blockchain Week 2026 / IstanHack: No hackathon - IBW 2026 (5th edition) confirmed held June 2-3, 2026 at Hilton Bomonti Istanbul. IstanHack ran with registration closing June 6, qualifier June 7-10, build phase June 14-21, winners announced June 27. Event is fully in the past. No 2027 edition announced as of August 2026. Site returning ECONNREFUSED during verification attempt.
• Korea Blockchain Week 2026 (KBW) + Hackathon: No hackathon - KBW 2026 (Sep 29 - Oct 1) is a confirmed conference with active ticket sales ($599 general, $99 student, ending Aug 27 UTC) and Upbit as main sponsor. The official site and ticketing page have zero mention of a hackathon. The separate event Korea Buidl Week / BuidlHacker 2026 (Mar 11 - Apr 18, 2026) did have a $26K hackathon with per-sponsor challenge tracks ($5K each: BNB Chain, Status Network, Near AI, YGG+Verse8, plus $6K general), but that event is already past. No 2027 edition announced for either event. No DoraHacks or Devpost listing found for KBW hackathon. The candidate brief incorrectly treats these as one event with a hackathon component.
• AI Tinkerers London - London Consumer AI Hackathon (a16z + ElevenLabs): No hackathon - Devpost page explicitly shows "This hackathon has ended." ElevenLabs blog post confirms event was November 2024. The candidate URL refers to the 2024 edition (Nov 9-10, 2024), not a 2026 event. No 2026 or 2027 edition has been announced. AI Tinkerers London does run 2026 hackathons but a different series (Aug 16 Agents vs Wall Street, Dec 11 ElevenLabs Worldwide Hackathon).
• ETHSilesia 2026: No hackathon - Luma page marked "Past Event". ETHWarsaw Twitter confirmed 350+ attendees, 100+ hackers, 44 projects. No 2027 edition announced on any channel (ethsilesia.pl, Luma, ETHWarsaw Substack, Twitter).
• CEE Blockchain & Fintech Week: No hackathon - Official site blockchainweek.ro is offline (ECONNREFUSED). fintechweek.ro and bitcoinbucharest.ro confirm a 2026 edition took place May 25-31 with hackathon May 30-31. The event is over; bitcoinbucharest.ro says "sold out -- next edition coming soon" with no 2027 dates. No active registration, no 2027 announcement found anywhere. Conflicting dates in aggregators (April 6-12 vs May 25-31) both refer to the already-past 2026 edition. No hackathon platform page (Devpost/DoraHacks) found. The 2026 hackathon had DeFi/fintech prize tracks and ~5,000 expected attendees but is now a past event.
• ETHCluj 2026: No hackathon - ETHCluj 2026 confirmed as a past 2-day conference (May 13-14, 2026) at Cluj Arena with ~200 attendees. Luma page (luma.com/3etvei3k) shows registration as closed/past. No hackathon component found on any platform (not on Devpost, DoraHacks, TAIKAI). Official website (ethcluj.org) was unreachable (ECONNREFUSED) at time of check. No 2027 edition announced on any source including Twitter/X, official site, or aggregators.
• Vienna Blockchain Week 2027: No hackathon - Official site viennablockchainweek.org confirmed: 2027 edition dated June 2-3, 2027, at Web3 Hub Vienna DC Tower 3. Super early bird tickets live (69 spots, 108-228 EUR). Sponsorship tiers listed (Platinum/Gold/Silver/Bronze).

• ETH Dublin 2026: Cancelled - Official site ethdublin.io returns 404 (post-event teardown). Coingabbar article dated April 3, 2026 confirms the 4th edition ran May 29-31, 2026 at Dogpatch Labs. No 2027 edition announced as of August 2026. Event has already passed -- outside the target window of August 2026 to June 2027.
• Swiss Blockchain Hackathon 2026 (SBHACK): No hackathon - sbhack.trustsquare.ch returns HTTP 404. trustsquare.com homepage has zero mention of any hackathon or SBHACK program. The SBHACK news blog (fetched via sbhack.trustsquare.ch/news) shows the most recent post dated November 1, 2021 (SBHACK21 winner announcement). SBHACK22 was merged into HackZurich as a blockchain track rather than a standalone event. No SBHACK23, SBHACK24, SBHACK25, or SBHACK26 editions found anywhere. No Devpost, Luma, DoraHacks, or TAIKAI page exists. No social media announcements found. The October 29-31 2026 dates cited by aggregators (swissdevjobs.ch) are recycled from SBHACK21 which ran October 29-31 2021 - a classic aggregator date-recycling trap.
• Berlin Blockchain Week 2026: No hackathon - The 2026 edition (June 13-21, 2026) is confirmed and documented across multiple sources including the official site blockchainweek.berlin and aggregators. However, the event is entirely in the past -- today is August 19, 2026. ETHBerlin04 (the main hackathon sub-event) was held in May 2024; no ETHBerlin 2026 edition was announced or occurred. The umbrella Berlin Blockchain Week has no central hackathon of its own -- it is a decentralized collection of independent community events. No 2027 edition has been announced by either Berlin Blockchain Week or ETHBerlin.
• HackOnChain Berlin 2026: No hackathon - The Devpost page hackonchain.devpost.com explicitly states "This hackathon has ended" and lists dates as November 23-24, 2022 with 104 hackers. The Warsaw edition (hackonchain-warsaw.devpost.com) also ended in May 2023. No 2026 or 2027 edition has been announced on Devpost, DoraHacks, Devfolio, or in any web search. NBX Next Block Expo 2026 ran March 24-25, 2026 in Warsaw without a HackOnChain co-located hackathon. The candidate "November 23-24" dates in the source note exactly match the 2022 Berlin edition, confirming the aggregator recycled stale data as if it were upcoming.
• ETH Quantum Hackathon (ETH Zurich): No hackathon - The 2026 edition (8-10 May 2026) is confirmed as a completed past event. ETH Rector welcomed attendees, confirmed on X by Andreas Wallraff (@AndreasAtETH). The QEC homepage currently shows "no events" for 2027. No 2027 edition has been announced.

LI.FI tweeted live sponsorship ("in 2 days in London") with $6,500 prizes on or around January 14, 2026. LinkedIn post by LI.FI titled "Encode's Hyperliquid Hackathon Winners January 2026" confirms the event concluded with winners (Mina, HyperGate, Delta0). Encode Club's own tweet called it "Your first hack of 2026." No 2027 edition has been announced as of August 19, 2026.
• ETHGlobal Lisbon 2026: No hackathon - Eventbrite listing shows "Event ended" for July 24-26 2026. ETHGlobal events page confirms Lisbon 2026 as a past event. Application deadline was July 17, 2026.

• ETH Warsaw: No hackathon - ETHWarsaw /hackathon page returns 404. Their Substack (May 2026, post-ETHSilesia recap) announces no Warsaw hackathon for 2026/2027. Twitter activity confirms pivot to Kolektyw3 hub model and small meetups. ETHSilesia Hackathon (Katowice, April 16-19 2026) was the only hackathon run by this team in 2026 and it is already past. No registration page, no prize pool, no sponsor tier exists for any 2026/2027 Warsaw edition.
• ETH Bucharest 2026 -- Strategic Pause: Cancelled - Official website ethbucharest.ro explicitly states "ETH Bucharest 2026 -- A Strategic Pause" with text: "This isn't an ending, it's a deliberate pause." Two search queries and the official site all confirm no 2026 event. No DoraHacks, Luma, or Devpost listing for 2026/2027 found. Last meaningful X post from early 2026 confirms the pause announcement.
• Permissionless IV Hackathon (Blockworks): No hackathon - Luma event page explicitly marks this as a "Past Event" with closed registration. Blockworks' own events page lists no Permissionless V or any 2026/2027 hackathon. All official Blockworks pages confirm dates as June 22-23, 2025. Aggregators (coinpedia.org, alternativeinvestorportal.com) that label this "2026" are recycling the event description with wrong year metadata -- a classic aggregator trap. The conference itself (Permissionless IV) was June 24-26, 2025 at Industry City, Brooklyn. No Permissionless V has been announced as of August 2026.
• Nordic Blockchain Conference 2026: No hackathon - Official site confirms May 26-27 2026 dates, Stockholm. Wrap-up article published confirming event concluded. No hackathon track, no prize pool, no Devpost/DoraHacks/TAIKAI page found. 2027 edition not announced.
