Trusting the Chain: Hunting for RPC Bugs in Ethereum Clients
![The Ethereum client’s request-response cycle operates as a layered system, where remote procedure calls [latex] RPC [/latex] facilitate communication between application logic and the blockchain, acknowledging that even decentralized systems are subject to the constraints of sequential processing and the inherent latency of network interactions.](https://arxiv.org/html/2601.21593v1/x1.png)
A new approach to fuzzing Ethereum clients uncovers hidden inconsistencies in RPC responses by intelligently simulating realistic blockchain conditions.

Hytale has been updated several times since its launch. The game was nearly cancelled, but was saved and released on PC in early access on January 13th. Even though it’s only been a few weeks, the developers have already added features like character customization and even dinosaurs! Now, the team is changing how they plan and release future updates.
As the inimitable CEO Simon Gerovich proclaimed with the gravity of a man announcing the discovery of a new continent:
In a recent proclamation, Binance has revealed that its Secure Asset Fund for Users-yes, that very fund designed to cushion the fall of beleaguered users from the perils of hacks and unforeseen calamities-will now don the glorious robes of Bitcoin. Oh, what a transformation! Such a strategic shift amidst the tempestuous winds of market volatility!

Released in 2017, Nioh is an action role-playing game developed by Team Ninja and published by Koei Tecmo. Players take on the role of William Adams, an English sailor who became a samurai in 17th-century Japan. The game received excellent reviews, earning an 88% average score from top critics on OpenCritic. In 2020, Team Ninja released Nioh 2, a sequel that refined and improved upon the original. Both Nioh games have since become highly praised as some of the best games in the ‘Soulslike’ genre, so Nioh 3 has a lot to live up to.

A new analysis technique leveraging the structure of quantum channels promises more efficient decoding algorithms for critical error-correcting codes.

It’s common for role-playing games to offer choices in dialogue that lead to different endings or branching storylines. You might be surprised to discover which RPGs also feature multiple endings, sometimes revealed very late in the game. We won’t reveal any major plot details, but be aware that these games have more than one possible conclusion.

LEGO has remained a beloved and popular toy for generations. Its appeal spans all ages, from children enjoying classic building sets to adults tackling complex models with thousands of pieces. Beyond the official sets, a dedicated community of fans creates impressive custom designs. LEGO even encourages this creativity with its Ideas program, which allows fans to submit their designs for a chance to become official LEGO products. Because of the brand’s widespread popularity, these incredible fan-made creations are frequently shared online, inspiring others and showcasing the limitless possibilities of LEGO building.

C’était un jeudi noir, mes chers amis! Le Bitcoin s’est retrouvé à 82 000$, après avoir osé plonger même jusqu’à 81 000$ pendant les heures de négoce aux États-Unis. Quelle audace!
In a move that screams “we’re either geniuses or completely unhinged,” Strive Inc., the publicly traded asset management firm with a Bitcoin obsession, just flexed its financial muscles. On Jan. 28, they closed an upsized and oversubscribed follow-on offering, because apparently, investors are still throwing money at anything with the word “Bitcoin” in it. Oh, and they bought more Bitcoin. Shocking.
