every trader claims the news moves the price. i spent my final year at university testing whether that's actually true. my thesis: an ML pipeline that takes media sentiment + market indicators and predicts whether solana closes up or down the next day. random forest vs a performer transformer, each trained with and without sentiment. defended it last week. the honest results after months of work: sentiment carries some signal. it ranked among the most important features. but it didn't consistently improve predictions. its value depends entirely on the model you feed it to. my favorite finding was a trap: the model with the best F1 looked like a winner on paper. the confusion matrix told the real story. it was predicting UP almost every single day. great metric, useless model. daily crypto direction stays close to a coin flip. anyone selling you certainty is selling the narrative, not the data. so today this cast is three things: 1. the end of my degree 2. my full thesis, linked below (fair warning: it's in spanish) 3. the starting line. smart contract security + applied ML on crypto data is next full pipeline in the repo. https://github.com/usctrabajo/TFG-sentimiento-solana/blob/main/tfg.pdf https://github.com/usctrabajo/TFG-sentimiento-solana

every social network dies the same way. early users come for the people, late users come for the audience. the moment the second group outnumbers the first, posts stop being conversation and start being distribution. no algorithm change fixes that, its demographics

jesse admitting the social bet failed is the most valuable cast of the year and nobody is reading it right. the lesson is not that onchain social is dead. its that you cannot bootstrap culture with financial incentives. base paid people to create and got extraction. farcaster never paid and got community. subsidies attract mercenaries, constraints attract believers. which one is your protocol optimizing for

unpopular opinion but most onchain identity projects are solving reputation for people who already have it. the anon dev with no github and no linkedin shipping bangers is the actual user. who is building for them

hot take but public goods funding created a class of builders optimizing for grant narratives instead of users. the pitch deck says infrastructure, the repo says abandoned in 4 months. meanwhile some anon with zero funding ships a tool people actually use daily. incentives are the product. change my mind
