Alfredo Roisenzvit opens his talk by framing Argentina’s paradoxical economic trajectory: once a top‑five GDP‑per‑capita nation in the early 1900s, it now ranks among the world’s most underdeveloped economies. He cites Simon Kuznets’s famous quip that there are four kinds of countries—developed, underdeveloped, Japan and Argentina—to illustrate how Argentina’s decline is as puzzling as Japan’s rise. The presentation traces the country’s slide from a double‑Japan per‑capita income in 1902 to a steady fall in world rankings after the World Wars, driven by a series of policy missteps. Roisenzvit drills into the data, highlighting chronic fiscal deficits, repeated sovereign defaults (the world’s “champion” in this regard), and three hyperinflations that have eroded confidence in the peso. He notes that every adult over 50 has lived through at least three 50‑plus‑percent‑monthly inflations and multiple deposit confiscations. The resulting currency debasement forced Argentines to anchor their finances to the US dollar, creating a fragmented exchange‑rate market and a largely informal cash‑based economy. Private‑sector loan‑to‑GDP ratios hover just above 10%, far below the 60‑80% typical of developing nations and the 150% seen in advanced economies. Despite these headwinds, Roisenzvit points to a resilient entrepreneurial spirit: Argentina has produced 11 unicorns—the most of any underdeveloped country—and ranks highly in cryptocurrency adoption. He argues that Ethereum’s decentralized finance stack offers a “golden bridge” for Argentines to bypass restrictive banking rules, access stablecoins, and conduct 24/7 transactions. His own venture, a peso‑denominated stablecoin called Dipe, promises instant, fee‑free conversion of fiat pesos into a blockchain‑based token, enabling on‑ and off‑ramps, B2B payments, and high‑yield staking. The broader implication is that blockchain technology could become a de‑facto financial infrastructure for economies plagued by chronic inflation and institutional decay. By providing a reliable, dollar‑pegged digital medium, DeFi tools may attract foreign investment, lower transaction costs, and give Argentine entrepreneurs a pathway to global markets—potentially reshaping the country’s growth prospects if complemented by sound fiscal reforms.

David Utro, a senior leader at Santiment, opened his EF DevCon talk by positioning the firm as an early‑stage crypto data pioneer that has evolved into a comprehensive behavioral‑analytics provider. He emphasized Santiment’s mission to empower retail investors—often the most...

Good morning everyone. Today Sebastian Lorenz unveiled AMP, a purpose‑built blockchain‑native database designed to treat blockchain data as a first‑class domain rather than an afterthought. By constructing the system from the ground up on modern data‑processing primitives, AMP aims to...

Great, thank you so much. As co‑founder of Espresso Systems, Jill Gunter opened her talk by announcing that the company’s Ethereum interoperability layer—named Espresso—has been live on mainnet for over a year, securing hundreds of millions of dollars in transactions...

The video opens with a vivid illustration of Argentina’s chronic currency devaluation, tracing the peso’s journey from a 1:1 peg with the U.S. dollar in 1881 to a staggering 1,500‑to‑1 ratio today. The speaker uses the metaphor of a 1,500‑mile‑tall...

The video introduces Stormbit, a DeFi fixed‑term lending platform that eliminates liquidations and over‑collateralization by leveraging zero‑knowledge trust‑less (ZKTLS) proofs to verify borrowers' creditworthiness without revealing their identity. Stormbit argues that DeFi’s $83 billion lending pool is a fraction of the $100 trillion...

The video, presented at DevConnect in Argentina, introduced X402, a new protocol that embeds payment functionality directly into the HTTP stack via the 402 "payment required" status code. By leveraging stablecoins and wallet‑based authentication, X402 aims to eliminate the cumbersome...

The Devconnect ARG panel explored how institutional finance can gradually migrate to decentralized finance (DeFi) by encoding market rules on Ethereum, while navigating regulatory red tape and compliance constraints. Speakers argued that institutions will seek tightly scoped compliance, incentivizing micro‑funds...

DevConnect Argentina opened as an Ethereum-focused developer conference dubbed “Ethereum Day,” featuring speakers from the Ethereum Foundation, local builders and application founders. Organizers highlighted Argentina’s outsized crypto adoption—roughly 20% ownership and more than 5 million daily users, or about 10%...

Ethereum is scaling.

Modexp seems to be by far the worst offender in terms of ZK-EVM prover-unfriendliness; up to 50x worse than average blocks. We really should do an EIP to replace the precompile with computationally equivalent EVM code (which would cost more gas) Very...
Incorruptibility is Ethereum's most important property.
ZKsync has been doing a lot of underrated and valuable work in the ethereum ecosystem. Excited to see this come from them!
Regular reminder: A key property of a blockchain is that even a 51% attack *cannot make an invalid block valid*. This means even 51% of validators colluding (or hit by a software bug) cannot steal your assets. However, this property does not...

Devconnect Argentina positions itself as a modern "World's Fair" for Ethereum, running November 17–22 and showcasing the blockchain’s transition from theory to real-world applications. The event markets Ethereum as a global, living network that enables solutions beyond traditional infrastructure, emphasizing...

Guests from academia and the Ethereum Foundation explained why specialized block builders emerged: extracting complex MEV (maximal extractable value) opportunities requires sophisticated tooling and continuous market activity that ordinary validators are ill-equipped to perform, so builders and middleware like MEV-Boost...
I really appreciate both @sandeepnailwal's personal contributions and @0xPolygon's immensely valuable role in the ethereum ecosystem. To recap: * Polygon hosts @Polymarket, which is probably the single most successful example of a "not just boring finance" app that has actually been successful...
