This post takes a deep dive into the evolving realm of blockchain scalability. It explores both layer-one and layer-two solutions, next-generation innovations, as well as emerging techniques that enhance transaction speed and efficiency. We cover topics ranging from sharding and consensus algorithm improvements to state channels and rollups. In addition, this post provides background context, practical... - Source: dev.to / 21 days ago

Blockchain is essentially a decentralized digital ledger which records transactions on multiple computers so that the record cannot be altered retroactively. Originally popularized by cryptocurrencies like Bitcoin and Ethereum, blockchain has evolved into a technology that ensures data integrity, transparency, and enhanced security. For those new to this topic, a deep dive on the basics can be found at what is... - Source: dev.to / 25 days ago

As the DeFi and NFT ecosystems expand, so does the adoption of Layer 2 solutions. The Arbitrum sequencer is expected to see broader adoption, with more dApps migrating to its scalable network. Works like those by Ethereum illustrate the growing enthusiasm for such technologies. - Source: dev.to / 25 days ago

This post explores how Decentraland—a decentralized virtual world built on the Ethereum blockchain—is revolutionizing cybersecurity training through immersive cyberwar simulations. We discuss the background and context of blockchain-powered virtual environments, detail the core simulation concepts like offensive "red teams" and defensive "blue teams," provide real-world applications and use cases, examine... - Source: dev.to / about 2 months ago

The NFT arena has exploded in popularity since its debut, providing a platform for artists and innovators to offer tangible proof of digital authenticity. NFTs allow the uniqueness of each digital asset to be verified on a blockchain, making them highly sought after by collectors and enthusiasts alike. The recent entry of Trump-themed NFTs into this space marks another milestone as it taps into a politically... - Source: dev.to / 3 months ago

We could have made some changes at the librdkafka level (see this), but we didn’t really want to pursue this (at least not yet). - Source: dev.to / over 2 years ago

As my first "real world" (ish) project in Vlang, I'm trying to copy https://github.com/confluentinc/confluent-kafka-go, which is a Go wrapper for Kafka C client library, https://github.com/edenhill/librdkafka. Source: over 2 years ago

If you're using Kafka in a Node.js app, it's likely that you'll need node-rdkafka. This is a library that wraps the librdkafka library and makes it available in Node.js. According to the project's README, "All the complexity of balancing writes across partitions and managing (possibly ever-changing) brokers should be encapsulated in the library.". - Source: dev.to / over 2 years ago

You are right, but in practice that's not what happens. Companies do not rely on open source libraries, the developers working for such companies do. I can give you a realistic example. If you want to use Kafka and Go, your probably only option is to use https://github.com/confluentinc/confluent-kafka-go. Its LICENSE explicitly says "no warranty". Now, what if I find a bug in the library? Only two realistic... - Source: Hacker News / over 2 years ago
