The Complexity of Measuring Speed in Blockchain

One of the exciting aspects of watching Olympic swimming competitions is the straightforwardness in determining the fastest swimmer. Competitors dive into the same pool, swim their hearts out, and at the conclusion of the final lap, one individual touches the wall first, claiming victory. However, this simplicity is starkly contrasted in the world of blockchains, where engineers are constantly unveiling increasingly powerful and faster systems. The landscape is made even more intricate by the diversity of use cases and transaction types that differ from one project to another, along with the various tools and methods employed to gauge performance.

This complexity also extends to the designers of cryptographic tools, particularly when it comes to the numerous ways of reporting hashes per second. Against this backdrop, the Polyhedra Network—an innovative team focused on developing a crucial blockchain component known as a cryptographic “prover”—embarked on a mission to create a new platform called “Proof Arena.” This platform aims to serve as a testing ground for various proof systems.

Just a few months prior, the Polyhedra team launched an open-source zero-knowledge proof system, which is often utilized in auxiliary blockchains referred to as “layer 2s.” This system was touted as being “nearly 2x faster than its counterparts.” But how did they arrive at this conclusion? Eric Vreeland, the Chief Strategy Officer at Polyhedra, explained that the team decided to develop Proof Arena to provide developers with a controlled environment to assess different provers. This initiative is designed to facilitate evaluations of the performance of various proof systems for specific proof generation tasks.

According to a press release, “Proof Arena will enable creators of ZK-proof systems to compare their solutions against others in a clear and scientific manner while ensuring that all controllable variables remain constant.” The outputs generated by the testing system encompass proof generation time, peak memory usage, and setup time, as elaborated by Vreeland.

To illustrate, builders of the provers can submit their systems “for inclusion in the arena,” Vreeland noted. Initially, the project will focus on generating benchmarks for Polyhedra’s own “Expander” ZK-proof system, alongside Polygon’s Plonky3, StarkWare’s Stwo, and Linea’s Gnark.

The team has ambitious plans to support all open-source proof systems and will provide benchmarks for frequently executed ZK tasks such as Keccak and Poseidon hash verification, tested across a range of machine configurations. While this may sound like technical jargon to some, for cryptographers, it represents the core of their interests and challenges. The platform offers a valuable opportunity for experts to demonstrate their capabilities in a competitive and innovative environment.

Tesla Semi Fire: NTSB Preliminary Report Released

The National Transportation Safety Board (NTSB) released a preliminary report stating that a Tesla Semi electric truck in California required firefighters to use “50,000 gallons” (approximately 190,000 liters) of water to extinguish a roadside fire. Firefighting teams also deployed an aircraft to drop fire retardant on nearby areas as a precautionary measure to control the fire.

The accident occurred on August 19 at 3:13 AM local time on the I-80 highway east of Sacramento. The electric truck went off the road while navigating a curve, collided with a roadside boundary marker, and then struck a tree, coming to a stop. Fortunately, the driver was not injured in the accident; however, considering their health condition, they were taken to the hospital.

The Tesla Semi’s large 900 kWh battery caught fire upon impact, and toxic smoke began to spread during the fire. While the fire continued with temperatures reaching up to 538°C, firefighters worked intensively to cool the blaze with water. However, due to the fire’s effects, the vehicle continued to burn until late in the afternoon. Meanwhile, Tesla sent a technical expert to the scene regarding fire safety and high voltage hazards.

The highway reopened to traffic at 7:20 PM local time, 16 hours after the accident. The NTSB, as an organization that can only make recommendations and cannot enforce regulations, sent a team to the area for investigation purposes. This major accident raised several issues, including dangerously hot fires and toxic smoke, which will attract the attention of many international organizations.

The NTSB had previously stated in 2021 that fires in the batteries of electric vehicles pose serious risks to emergency response teams and that the guidelines provided by manufacturers for such fires are inadequate.

New Leaks About Samsung Galaxy S25 Ultra

Samsung is expected to introduce the Galaxy S25 Ultra along with the Galaxy S25 series at the beginning of 2024, likely in January. Although no official announcement has been made yet, leaks regarding the upcoming flagship continue to spread rapidly on the internet. Notable leak source IceUniverse shared several new visuals of the Galaxy S25 Ultra in a post on the X platform. These visuals reveal the design differences between the Galaxy S25 Ultra and the Galaxy S24 Ultra.

One of the notable features in the leaked images of the Galaxy S25 Ultra is the rounded corners of the phone. In contrast, this year’s Galaxy S24 Ultra has quite sharp corners, which has led to feedback from some users indicating discomfort while holding the device. Previous leaks have suggested that the Galaxy S25 Ultra may be somewhat larger.

A tweet shared by IceUniverse: Galaxy S25 Ultra Image

According to leaks, the Galaxy S25 Ultra is expected to be thinner and lighter compared to previous models. In August, rumors emerged that the upcoming Galaxy S25 Ultra would be lighter than its competitors, with a weight of under 221 grams.

Another image featured in IceUniverse’s post shows close-ups of the sides of both next year’s expected flagship phone and Samsung’s current flagship. In this image, the side of the Galaxy S25 Ultra appears flatter with rounded corners. While these changes may not create a major revolution, they will generally positively affect the feel of the phone in hand.

Looking at other rumors about the Samsung Galaxy S25 Ultra, it is expected that the company will offer top-tier screen and camera upgrades next year. Additionally, there is a strong expectation that the satellite connection feature will also be introduced alongside the Galaxy S25.

iOS 18 Officially Released: Here Are the Innovations!

Apple officially launched iOS 18 yesterday, as promised. After a long beta testing phase, this update brings many exciting new features for iPhone users.

iOS 18 Officially Released: Innovations and Features

New Features in iOS 18

Advanced Customization Options on the Home Screen: With iOS 18, users can now arrange app icons freely without sticking to the traditional grid layout. Additionally, there’s an option to change the colors of the icons and adjust their darkness levels. In short, you are no longer bound to a boring layout. It raises questions why Apple waited until 2024 to offer this feature.
Revamped Control Center: The Control Center is completely redesigned in iOS 18. Users will be able to group controls more comfortably, and developers can easily add controls from their applications. Also, there’s an option to divide the Control Center into pages, allowing different controls on each page.
RCS Messaging Support: With iOS 18, Apple introduces Rich Communication Services (RCS) messaging support. Users can add various effects to their texts and react with new emojis for more colorful responses.
Updated Photos App: The Photos app is presented with a new opening page and a modern layout. Users can now browse photos by time, people, and many other criteria, reorder media files, and explore more with the “Collections” feature.
App Lock Feature: Users can now lock specific applications. For example, they can activate Face ID protection from the menu that appears when long-pressing an app icon. Thus, anyone wanting to open the app will have to pass the Face ID protection first.
Apple Intelligence: One of the important features of iOS 18 is Apple’s artificial intelligence kit, Apple Intelligence. However, to fully benefit from this feature, you’ll need to wait for the iOS 18.1 update. More information about Apple Intelligence can be found here.
