Con l’avanzamento ufficiale della versione Bitcoin Core v30, le modifiche alla strategia di inoltro di OP_RETURN stanno diventando un tema centrale tra la comunità Bitcoin e l’ambiente dei miner. Secondo la documentazione tecnica pubblica, l’aggiornamento rimuove il limite di inoltro di 80 byte per OP_RETURN, in vigore da oltre dieci anni; con la configurazione predefinita, i nodi permetteranno a una singola output di trasportare quasi 4MB di dati. Gli sviluppatori sottolineano che si tratta di un cambiamento a livello di relay policy, senza modificare le regole di consenso come la dimensione del blocco; tuttavia, l’impatto reale sulla struttura del mempool…

Tras la activación de Bitcoin Core v30, el cambio más llamativo fue la eliminación del límite de 80 bytes en OP_RETURN, ampliándolo hasta niveles cercanos al tamaño máximo del bloque — la cantidad de datos basura que puede introducirse en una sola transacción aumentó instantáneamente unas 50.000 veces respecto al pasado. La carga de datos en la red ha aumentado aproximadamente 50.000 veces frente a niveles anteriores. Según los desarrolladores, esto representa un 「Bitcoin más abierto」, pero para los mineros significa: los bloques se convierten en discos de almacenamiento, la mempool se llena más rápido y tú eres quien paga,…

Beating yourself up for sitting out Sunday’s TCS New York City Marathon? Don’t — your body might actually thank you. From blistered feet and aching joints to a churning stomach and battered muscles, the iconic 26.2-mile race can wreck far more than just your ego. “Running a marathon is an incredible physical and mental achievement, but it’s also a demanding event that places unique stresses on the body,” Dr. Mariam Zakhary, director of running medicine for Mount Sinai’s Department of Rehabilitation and Human Performance, told The Post. More than 50,000 runners are expected to run the NYC Marathon on Sunday,…

A jarring collision with a rude skier changed the course of Liz Healy’s life in unimaginable ways. That fateful trip to Vermont in 2022 left Healy in excruciating pain. The MRI results were shocking — she had a fractured sacrum and a kidney tumor. She was diagnosed with Stage 2 kidney cancer. Further testing revealed the incomprehensible — she also had Stage 4 colon cancer that had spread to her liver and lymph nodes. Liz Healy, 49, was diagnosed with Stage 2 kidney cancer and Stage 4 colon cancer in 2022. She’s set to take on Sunday’s TCS New York City…

Step aside, outdated exercise goals.  For years, 10,000 steps has been promoted by fitness trackers, health apps and medical professionals as the gold standard for daily physical activity. But if that so-called magic number feels more intimidating than inspiring, rest assured: It’s a product of marketing, not science, and there are key benefits you get from a lot of lower step counts, too. The 10,000-step rule isn’t as golden as it seems.

Sorry, fellas. New research suggests that men may need to exercise twice as much as women to lower their chances of developing a major health threat that kills them more often. “This study provides strong evidence that a one-size-fits-all approach cannot and should not be used to guide physical activity recommendations for men and women,” Dr. Emily Lau, a cardiologist, wrote in an editorial. In response to their new findings, scientists are calling for the development of sex-specific exercise guidelines.

On the dance floor, Phyllis Bogart moves like she’s made of electricity, not metal. At 78, her pink-and-purple-streaked curls bounce as she shimmies and shakes with the energy of someone half her age, each twirl punctuated by a wide, wild grin. It’s clear that four hip replacements, a mechanical knee and a string of other surgeries haven’t slowed her down — though they did earn her a nickname. “With all the titanium in my body, I’ve become known as the bionic babe,” Bogart told The Post. Phyllis Bogart discovered the Pacemakers after her beautician recommended she join the group. She’s…

Is your phone sabotaging your gains? New research suggests that popular calorie-counting and workout-tracking apps may be doing more harm than good, leaving users feeling frustrated rather than fired up to reach their goals. That’s bad news for the 92 million Americans who rely on these platforms to track every bite and bench press, raising questions about whether the tech meant to help them is actually holding them back. Digital health tracking apps have surged in popularity in recent years. Prostock-studio – stock.adobe.com In the study, researchers at University College London and Loughborough University analyzed 58,881 posts on X (formerly…

A US Navy vet did walking lunges for more 4.06 miles — breaking two world records in the process. Mike McCastle, 38, completed his knee-crippling feat of endurance across Utah’s Bonneville Salt Flats as part of a lifelong challenge to complete 12 extreme sporting missions.
