Account Abstraction Panel

Account Abstraction: Experts agree, if we don't have Account Abstraction, then Ethereum is at stake! Your private key wallet will soon be a thing of the past. Account Abstraction promises to put programmability into every Ethereum wallet, and unlock new frontiers for both developers and users. How will Ethereum be different, when every wallet upgrades to a smart wallet? What will it take to get there? What commercial use-cases emerge? What other parts of Ethereum does AA touch?

Art Reflects What Happens in Society

I have always say and believe that art reflects what happens in society. From Renaissance to Cryptopunks, I am going to take you on a journey of the history of art, and why after the covid19 NFTs became popular, even though they were actually created in 2012 with the colored coins. Based on my own experience as the 1st female cryptoartist in Colombia, we will learn with what I like to call my"street" experience and discover the power of a female in a men dominated space.

Borderless Africa - a New Narrative

If Ethereum is a digital nation, millions of Africans will flock in masses to become citizens. Why? A fair chance to participate in an open borderless economy, and ultimately self-determination. Web3 is unleashing a generation of African talent trapped within the confines of the old gated economy. A new narrative places Africa differently through the Web3 lens. Why should Ethereum builders take African talent and markets seriously? Where are low hanging fruits for win-win scenarios?

The Unbanked, A Real Blue Ocean Opportunity for Crypto

1/4 of the global population is excluded from the current financial system. Financial exclusion stems from the belief that a population is too high risk to receive funding. Sadly, this factor preeminently causes these same people to never be able to break out of poverty. Unbanked farmers fall in the same boat. Due to their lack of collateral and credit history, they can only access loans starting at 100% interest rate. Crypto and blockchain has an opportunity to change that for the better.
