The Ethereum Foundation opened ticket sales for Devcon VI in Bogotá, Colombia through a competitive on-chain auction built by the TrueFi development team and deployed on Arbitrum, requiring a minimum bid of 0.25 ETH. The process, announced June 28, 2022, ran alongside a separate raffle and a scholars program offering 50 fully funded places for builders who could not otherwise attend. The event took place October 11 to 14 at the Agora Bogotá Convention Center, marking the first time Devcon had ever been held in Latin America.

What the Auction Actually Required

The auction opened July 5, 2022 at 08:00 UTC and closed July 14 at 07:59 UTC, a window of almost exactly nine days. The top 20 bidders won tickets outright. Everyone else who bid above the 0.25 ETH floor was entered into a raffle for 80 additional tickets. Bidders who did not win could withdraw their full deposit, minus a 2% fee designed to prevent one person from submitting multiple bids with different wallets, a practice known in crypto as a sybil attack.

All payments were processed in ETH on Arbitrum, the largest Ethereum Layer 2 network by total value locked at the time. Arbitrum held roughly $3 billion in assets and about 55% of the L2 market at that point. The Ethereum Foundation's choice to use a Layer 2 rather than the Ethereum mainnet was deliberate: transaction fees on Arbitrum had just been cut by roughly 50% following its Nitro upgrade. Using a live Layer 2 for real ticket purchases was itself a demonstration that the technology works in practice, not only in developer tests.

That same choice introduced a structural barrier for builders in parts of sub-Saharan Africa and South Asia, where centralized exchange on-ramps capable of bridging funds to Arbitrum were limited at the time. The friction of converting local currency into ETH and then bridging it to a Layer 2 network added steps that were manageable in some markets and genuinely prohibitive in others. This tension between showcasing new infrastructure and ensuring that global participation is practically achievable is one the Ethereum community has not fully resolved.

There was a meaningful catch. Certain smart contract wallets, including Argent and Gnosis Safe, were not compatible with the auction contract. Organizers acknowledged the issue but did not offer an alternative before the window closed. In regions where hardware wallets are rare and users depend on more accessible wallet interfaces, this created quiet friction.

A total of 268 people participated in the on-chain raffle and auction combined.

The Dollar Value Varied Sharply by Region

At the time of the announcement, ETH was trading near $1,000 to $1,200. The bear market had already taken it down roughly 80% from its November 2021 high of $4,878, and June 2022 turned out to be the second worst month in ETH's price history, with a 45.4% drop. At $1,100 per ETH, the 0.25 ETH floor came to roughly $275.

That number looks different depending on where a prospective attendee lives. In Nigeria, where builders represent approximately 3% of global blockchain developers according to a 2024 Mariblock report on Nigerian blockchain startups, $275 represented a significant share of income for many potential participants at mid-2022 exchange rates. For builders in India and Pakistan, the documented barriers centered more on visa logistics and travel routing than on the floor price in dollar terms; the Scholars Program was designed to address both.

The bear market did at least reduce the floor price in dollar terms compared to what it would have been at 2021 peaks. A 0.25 ETH bid in November 2021 would have cost over $1,200.

General admission tickets outside the auction were priced at $599, with builder tickets at $299, student tickets at $149, and volunteer positions available at no cost. The Foundation noted at the time that more than two thirds of all Devcon tickets were either discounted or free.

The Scholars Program Was the Structural Access Solution

Running separately from the auction, the Devcon Scholars Program offered 50 full scholarships covering the ticket, flights, accommodation, a daily allowance, and visa application support. Applications closed August 1, 2022. The program was open to developers, researchers, community organizers, journalists, and students globally, with explicit focus on those who could not attend without financial help.

Visa support matters more than it might seem. Indian and Pakistani nationals face documented difficulty obtaining Colombian tourist visas, and routing from Lagos or Nairobi to Bogotá often requires connecting through Europe or the United States.

The prior cohort at Devcon V in Osaka supported 53 full scholarships and 8 partial ones from 25 countries, including Nigeria, Egypt, Argentina, Afghanistan, and Syria. The 2022 program offered the same coverage categories.

"We want to make Devcon a hub of Ethereum innovation by ensuring the most talented builders in our ecosystem can attend, regardless of their circumstances," the Ethereum Foundation wrote in its scholars announcement.

Why Bogotá, and Where This Trajectory Points

The Foundation chose Bogotá after competition among several Latin American capitals. Approximately 14 regional community events were organized across Latin America ahead of the conference, and organizers held an ETH Latam Day the day before Devcon opened.

Final attendance reached more than 6,000 in person, with 60,000 viewers watching the livestream globally, including 21,780 on the first day. All proceeds from the auction and raffle were donated to Ethereum public goods projects.

Ethereum Foundation Executive Director Aya Miyaguchi reflected after the event: "Builders going out to see different parts of the world they're trying to change remains essential to Ethereum's mission of global impact."

The trajectory since Bogotá reinforces that framing. India became the top source of new crypto developers globally by 2024, accounting for 17% of new entrants per Electric Capital data.

The next Devcon, scheduled for November 3 to 6, 2026 in Mumbai, is the clearest institutional acknowledgment yet of South Asia's weight in the ecosystem. For builders in Africa and South Asia who encountered structural barriers at Devcon VI, the scholars model and the Mumbai location represent incremental progress on a problem the Ethereum community has not yet fully resolved.
