- Chainlink Bootcamp day 9. Today we made code to bring on-chain the temperature in any city: 0xae523D5B6123F6ed6A51A2eC99F4E134aBF75769
- Chainlink bootcamp day 8 - Generating Random Numbers Using Chainlink VRF
We prepared code for dynamic NFTs of characters which ran a random distance each time the code was executed, pitching characters against each other
Orc beats Elf!

- Chainlink bootcamp day 7: Cross-chain NFT minting
We developed code to mint smiley face NFTs (smile depending on BTC price going up, down, or flat) in Ethereum Sepolia (blue) sending the trigger in Avalanche Fuji (red NFT) or Polygon Mumbai (purple NFT): https://testnets.opensea.io/es/collection/crosschain-price-845
- Chainlink bootcamp day 6: Dynamic NFTs updated with Chainlink feeds.

- Just saw an inspiring video by Sergey Nazarov from Chainlink Labs explaining the relevance of crypto for everyone.
Crypto takes us from a probabilistic world (such as a bank asking you to deposit money and promising returning your money when you ask for it, but with no guarantee, as you depend on the people who control the bank, who might decide not to pay, or go bankrupt) to a deterministic world (where the bank does not even have the option to keep your money once you ask for it, because you have direct control).

- Chainlink bootcamp day 4: Use CCIP to transfer USDc between chains, from Avalanche Fuji to Ethererum Sepolia.
It works!

- Chainlink bootcamp day 3
Just created an ERC-20 token on Sepolia and a shop which gives it automatically when it receives Sepolia ETH
Token: 0xb7Ed0c5975Bb80730420caD8Cf7C873c437C48a0
TokenShop: 0x3BDe3f9f54a44EF7cB5e2Fc12063C6A427C27384
- Yesterday in the chainlink bootcamp I deployed a simple contract in Sepolia to create an array to register and change strings: https://sepolia.etherscan.io/address/0x0f6bd0d9bb3e58c88e8702ce1129d47a77d733b0
- Acabo de terminar de leer el libro Read, Write, Own de Chris Dixon. Una lectura muy recomendable y accesible a todos los públicos.
El autor considera blockchain como la tecnología que permite volver al internet descentralizado, el que surgió con los protocolos de email y páginas web (web1), pero que un tiempo después ha pasado a estar controlado por las Big Tech (web2), que bloquean la innovación sobre sus plataformas por parte de terceros al tender a cerrar el acceso o cambiar cosas cuando quieren, lo que no da confianza ni es rentable para los emprendedores.
Su perspectiva es que blockchain nivela el terreno de juego, permitiendo a emprendedores y builders construir sobre una base fiable sabiendo que no van a cambiar las reglas del juego, y dando pie a una gran innovación, además de devolver el valor a los bordes de las redes (más valor para los usuarios). Lo enfoca como una tecnología disruptiva y sustitutiva con respecto de los modelos tradicionales, más que complementaria.
Creo que las empresas tradicionales hasta ahora no han tenido clara la propuesta de valor, y no se van a lanzar 100% con esta tecnología hasta que tengan competidores quitándoles el negocio. Igual que los bancos no han lanzado sus bancos digitales hasta que Revolut o N26 les estaban quitando clientes y habían demostrado que el modelo de negocio era viable.
Y tú, ¿qué piensas de blockchain y crypto como "nivelador" y "democratizador" del terreno de juego?
- Después de unos meses moviendo casos de uso de blockchain en empresas tradicionales, estoy con la sensación de que blockchain es más sustitutivo que complementario, ya que solo unos pocos casos de reducción de costes (automatización de supply chain y tokenizacion de RWA) parecen tener cabida. ¿Ideas de esto?
También me gustaría oír ideas de cómo aprovechar blockchain y crypto para mejorar ingresos en empresas tradicionales. De lo que he visto de casos de loyalty y similar, hasta ahora no parecen demostrar un retorno, y acaban pausándose (como el caso de Starbucks)
- Buenas!
- Gm from V2!!
- Privvy, an account abstraction solution that simplifies web3 login experience for users now allows logging in with Farcaster.
This is huge, as Farcaster already has a wallet associated to your profile, which means that this integration could lead to having the same wallet across multiple "abstracted" applications 💥
- If you're betting on Lens, you're betting on ownership
- Bitcoin looking good!

- Another step supporting rollups and decentralization. I quite like the protocol!

- A second case using flared gas to mine Bitcoin, leveraging what would normally be waste or an undesired by-product of an industrial process to produce something valuable.

- Société Générale is soon to launch EUR stablecoin!
Having digital cash listed by traditional banks is a big step towards cypto adoption, and allows for direct on-chain operations with tokenized assets such as bonds or shares.
Exciting times coming!

- Really excited about attending the cryptoplaza forum tomorrow!
- We will have Rodrigo Rato, former Vice President of the Spanish government, to speak about CBDCs, Stablecoins, and the Banking sector in the V Edition of Crypto Plaza Forum in Madrid 23/24 November https://www.linkedin.com/feed/update/urn:li:activity:7124722217220722690/
- España adelanta entrada en vigencia de la Ley MiCA

Esto abre las puertas a la entrada de toda la industria tradicional al mundo crypto y web3, estableciendo unas reglas claras del juego para las empresas, lo que dará lugar a grandes innovaciones en los próximos años gracias a la adopción que habilitará.

- Tron is on its way to become a payments solution: https://thedefiant.io/tron-quietly-becomes-the-leading-blockchain-for-stablecoin-transfers
Stablecoin payments is one of the first crypto use cases to find product-market fit and mass adoption, especially in markets with high inflation in their national currencies

- Time to listen to the weekly @bankless.lens rollup and work on some airdrops!
- Over 0.5M paid collects transactions on Lens (while in beta). Paid collects could have some serious monetization potential at scale. Building utility around the collected NFTs could unlock lot of that potential
- What is your favorite zkEVM L2?
For now I’m with Polygon zkEVM; cheap transactions and high yields on pools
- Today I started reading The Ethereum Investment Framework. Very relevant insights, quite useful also for my own business.
I like the comparison between the Internet and Ethereum, and how network effects drive a monopoly in digital platforms. If we are to have one with blockchain, public and decentralized sounds best
- Can't wait to be there!
- Hello World!
- Listened to the @bankless.lens weekly rollup. Eager to try out Scroll L2, and looking forward to the BTC spot approval!
- Just got my copy of principles of Economics by Saifedean Ammous.
Quite interesting takes in the first chapter: “the effect of a minimum wage is to make it illegal for workers with low productivity to get jobs, and many of these workers will lose their jobs”. Any thoughts on the above?
- Ethereum is about to get even safer!
This is how wallets are about to evolve
- I just minted https://hey.xyz/u/javivise.lens #lens
