Blockchain transaction fees are notorious for being a big adoption factor. @ethereum gas fees frequently reached highs over $100 and cruised on average over $20 in 2021-2022, down to $1 in 2025. Here, I’ll try to ELI5 how #Cardano Tx fees work 🧵👇

After some consideration, I think it might be really helpful for the Cardano Community to have another option for Administrator for treasury funded proposals. Would you like to see PRAGMA as an option?

I just voted YES to the Amaru Node Budget Request. Node diversity is of paramount importance, the team is super solid, and the budget is reasonable. TX hash 7d0faffd6b1ed204415f364754cabffa816b73a37a06c931b8a8170d762c198f Let's go @pragma_org !

Transparency is so important in our ecosystem. We've now posted PRAGMA's Statutes on our website for easy access. Clear rules matter and should be accessible to all. Please forgive us, we had them on GitHub but realize not everyone speaks 'nerd' fluently. pragma.io/statutes/

🚀 Excited to share that our paper "Serial Monopoly on Blockchains with Quasi-patient Users" will be presented at FC'25! Looking forward to discussing it in Japan 🇯🇵 with @PaoloPenna8. See you there!
New research from CF x @InputOutputHK! 📖 A research paper from @manv_sc & @PaoloPenna8 was accepted at FC 2025 (15% acceptance rate), exploring how transaction fees shape blockchain security and user behavior. A big step for Cardano research. cardanofoundation.org/blog/c…

Sure, When writing code to develop an application in the traditional world (non blockchain), usually, you have to interact with other services like for example a database. Now, most of the database provider (like mysql, postgres, oracle etc) have made super simple to run a database on your computer or laptop. When developing a dApp on Cardano, or other blockchain, you MUST talk to a blockchain. Cardano has 3 main chains: preview, preprod, mainnet. Developing against REAL blockchain can be slow and problematic: you must fund wallets you want to use, wait for blocks to be produced every 20 seconds etc etc... on top of that, you need to talk to the blockchain, so you need an account on maestro, blockfrost etc.... Even worse, if you're 40k feet on an airplane on a 10h flight, you can't work, coz you got no internet. A DevKit is a "kit" or "toolbox" which give you ALL you need to write a dApp on Cardano w/o being connected to interenet or something. Chain is superfast (1second block for example) and you can fund all teh wallets you want, mint tokens etc, just w/ a snap of the finger. 0 wait time. Blockfrost, ogmios and all this is running already for you, for free etc. As result, writing code is much faster experience, faster feedback etc and should make people happier and less frustrated. Does it help?

In case someone needs to hear this: the point of building an alternative node client is that we end up with MORE node clients. It's not about annihilating the existing implementation. Many can (must) coexist for a strong ecosystem.
