Today I got the #NFT from successfully completing the
@Starknet Basecamp!

I learned topics such as Starknet fundamentals, transactions, Cairo, Smart Contracts, and even some of the @ohayo_dojo engine.

Special thanks to @Dojo_Coding and @StarknetFndn.

@brolag @PrivacyScaling Excelente proyecto, con muchas ganas de verlo avanzar!

And today we concluded the @PrivacyScaling PSE Core program after some weeks working on contributions.

We based ours on generating proof of location to target real use cases.

Special thanks to @ImTheJaf, @AndyGuzmanEth and @ranulfovm.

@starklingsapp done!

Was a requirement for the @Starknet Basecamp and it was definitely a great resource to learn @CairoLang.

Thanks to @Dojo_Coding and @StarknetFndn for all the learning and resources.

1/ Han sido 5 increíbles semanas desde el inicio del PSE Core Program en Costa Rica. Empezamos con conceptos matemáticos aplicables a la criptografía y poco a poco nos adentramos en temas básicos y no tan básicos de este fascinante mundo. 🔐

7/ El último grupo, Proof of Conversion In Action, implementó una solución basada en ZKPs para autenticación por localización, con una interesante demo inspirada en un ejemplo reciente de la realidad nacional. 🌍🛡️@3rickDev @BetoDevW3 @richbm10 @robertosolanom @SebasZeledon
