This chapter presents the first empirical evidence of Bitcoin miner deviation from fair transaction norms, examines fee manipulation, and uncovers miner-user collusion via private networks and dark fees in both Bitcoin and Ethereum. It challenges assumptions in prior theoretical work and reveals transparency issues post-Ethereum Merge.

Each week, the HackerNoon team highlights standout Startups from our Startups of The Year database. Every featured startup has been nominated as the best in their respective technology category or region. This week, we present: YellowLyfe HQ, Sufle, and Green Cross United Kingdom

Compound’s on‑chain governance is active but heavily centralized: a handful of addresses hold and delegate most COMP tokens, only ~3 voters on average pass a proposal, voting fees can deter small holders, and delegate coalitions mirror each other’s votes.

TLDR: AI is super powerful but often feels like a mysterious "black box," and the tech giants running it hold a lot of control over our data. This lack of transparency and centralization causes privacy issues, censorship risks, and makes it hard for smaller players to innovate. To truly trust AI, we need to see how it works and where it runs. Technologies like...

Flipster announces partnership with TALON, one of Asia’s premier competitive gaming organizations. As part of the collaboration, TALon’S Dota 2 team will officially compete under the name Flipster Talon. Flipster will roll out co-created content, campaign drops, and digital fan activations.

Token concentration undermines DeFi governance—Balancer saw a large holder push self‑serving proposals, Alameda Research used its Compound tokens to skew collateral rules, and centralized exchanges risk voting on users’ tokens without consent.

Deadzone: Rogue has officially launched into Early Access on Steam. The game has received praise for its tight gunplay, progression, and intense co-op. The Full 1.0 Release will come with Zone 3, containing new enemies and weapons.

Decentralized AI is a new way to store, process and share data. It lets you control your data without having to deal with middlemen. Decentralised AI can help you get smarter results without snatching your diary and selling it to advertisers.

Space and Time launches its mainnet, introducing ZK-proven data queries for smart contracts. Here's how it could change onchain data access.

This chapter outlines a methodology using an Ethereum archive node and event logs to analyze Compound governance: proposal frequency, token distribution among voters, on‑chain voting costs, and delegate coalition patterns—revealing significant power concentration.

Flashbots now powers 2% of Ethereum txs in 52% of blocks, bundling public DEX calls or sandwich attacks with direct miner payouts to capture MEV. On Bitcoin, side‑channel “dark‑fees” let major pools (over 55% combined hash) collude to accelerate low‑fee txs into the top of blocks within 1–3 confirmations.

Learn ethical WiFi hacking with Termux and Wipwn. This guide covers setup, Pixie Dust attacks, WPS brute force, and tips to secure your network.

We created a code review guide to align expectations, improve feedback quality, and make reviews feel collaborative instead of gatekeeping. Here’s what worked for us.

You can control youtube form the command in linux. But it's a little work. This article lays out out how to get this working.

Finlight.me moved from Postgres full-text search to OpenSearch. The move was made to support the fast, flexible search at we were growing toward. OpenSearch is the fork of Elasticsearch, both for its technical capabilities and more favorable licensing model.

This guide provides a step-by-step process for installing Magnolia CMS version 6.2, covering prerequisites like Java, Node.js, and npm installation, setting up Magnolia CLI, downloading and starting Magnolia, and optional configurations for IP access and firewall settings. It includes references for further reading and troubleshooting.

Contention transparency fails in Ethereum as private relay networks like Flashbots and Taichi let miners receive transactions off‑chain. Nearly all major pools use these relays, and an active test showed Babel Pool (via Taichi/SparkPool) privately received and properly included transactions—undermining reliance on public mempool views.

Hacktivists are determined to combat misinformation through coordinated strategies, including truth-spreading bots, misinformation literacy, and hacking for political causes. They emphasize a social contract against misinformation and suggest evolving tactics to address the growing influence of false narratives online.

Monero stands out as a privacy-focused cryptocurrency that shields transactions from surveillance through innovative technologies like ring signatures, stealth addresses, and RingCT. While Bitcoin transactions remain transparent, Monero makes tracking nearly impossible. Regulators worldwide are struggling with this privacy-first approach, leading to exchange delistings and compliance challenges. Despite analytical attempts, Monero's encryption remains largely impenetrable, forcing a continuing tension between privacy rights and regulatory...

We use two large block ranges (Bitcoin 2018–20, Ethereum Sep 2021–Jun 2022), identify public vs. private bundles via fee heuristics, and run a Bitcoin test showing >50% hash‑rate pools collude on accelerated low‑fee transactions.
