blockchain

We are exploring an experimental blockchain mechanism called "Proof of Weather" In the world of blockchain, various methods are used to achieve network consensus. The most well-known is Bitcoin’s Proof of Work (PoW). While PoW is an excellent mechanism, it has one major drawback. It consumes an enormous amount of electricity. At one point, I found myself wondering: Does blockchain really require …

Running a Crypto Trading Bot on a $5 VPS: The Complete 2026 Guide I spent $47.99 on cloud hosting last year. Then I discovered I could run my entire crypto trading operation on a VPS that costs less than my daily coffee. Here's exactly how I did it — and why you should too. The Problem with Cloud Hosting When I first built my trading bot, I hosted it on AWS. Fine for prototyping. Terrible for a s…

On April 1, 2026, Solana's largest decentralized perpetual futures exchange Drift Protocol suffered an attack, losing approximately $285 million . This is the second-largest DeFi hack of 2026 (behind KelpDAO's $292M attack the same month). Together, these two incidents totaled $577M — 76% of all DeFi stolen funds in 2026 . Key Finding : This was not a smart contract vulnerability. The attacker pe…

I was testing Bitcoin Core 31.0 to see if I could make chains of unconfirmed transactions longer than 25. Release notes say: The mempool no longer enforces ancestor or descendant size/count limits. ...

I specced an on-chain credit ledger for a compute network, wrote the mint, and then the token program refused to initialize it. The two extensions I needed (non-transferable credits, plus a hook on every movement so the chain could run the accounting) are mutually exclusive on a single Solana mint. The runtime rejects the initialize instruction. That rejection sent me back to the design, and I ca…

The AI agent economy is scaling fast. Agents pay for APIs, buy data from other agents, settle trades, and manage resources autonomously. But running these agents on public blockchains introduces a critical flaw: surveillance . When every on-chain agent payment is public, an agent's entire financial graph becomes visible. Anyone can see who an agent paid, how much, and when. This reveals the agent…

Building a Zero-Gas-Fee Blockchain Traceability System for WooCommerce & Shopify on Polygon In modern agriculture, cosmetics, and luxury goods, transparency is no longer a luxury—it's a compliance requirement . Consumers want to scan a QR code and instantly verify a product's origin, quality certificates, and supply chain journey. However, building a blockchain-backed traceability app for e-comme…

I want to set up the latest Bitcoin Core version to mine a block that is valid after the BIP-110 is activated (two months from now). What are the steps to do at minimum? I want to make sure that a ...

I'm a blockchain dev from Rajkot, India. I built WorkChain — a protocol that pays AI agents automatically when they complete work. No invoice. No human approval. No middleman. It ranked top 10 out of 2,858 teams at the Colosseum Frontier Hackathon 2026 predicted by Colosseum AI copilot and that done by one of the judge. Here's what I learned that nobody talks about. The problem AI agents can do r…

Subtitle: Token-2022 showed me that tokens can have rules, not just balances. This week I moved past basic SPL tokens and started using Token Extensions. At first, I thought a token was mostly just: a mint token accounts balances transfers But Token-2022 adds something more interesting: behavior. A token can charge transfer fees. A token can display interest over time. A token can start every acc…

If you are automating blockchain operations today, you are probably running scripts. Maybe a Node.js bot on a VPS. A Python loop calling an RPC every 60 seconds. A cron job that wakes up, checks a price, and fires a transaction. I have written more of these scripts than I care to admit. And I am here to tell you: that pattern is dying. Not because the scripts stop working, but because the complex…

This is a step forward in institutional adoption of tokenized funds in global real estate.

In Web2 , asset distribution is controlled by backend services, databases, and business logic. In Solana , those rules can live directly inside the token itself. In this experiment, I explored how far Token-2022 Program can go by combining: Non-transferable tokens Token accounts across multiple wallets Transfers with protocol-level enforcement Token burning On-chain state inspection The goal was …

IntroductionElectronic health records (EHRs) increasingly anchor clinical decision support and population-scale analytics, yet their concentration of sensitive information amplifies disclosure risk, widens the attack surface, and faces emerging threats from quantum computing. Existing frameworks fail to simultaneously address privacy preservation, quantum-resistant security, and cross-institution…

I've been deploying smart contracts for a while and the workflow was always the same mess. Hardhat config. Deployment script. Forget to verify. No records. Start over next time. So I built Krionex to fix it. Here's a walkthrough of deploying a real ERC20 token to Base mainnet using it. What you need before starting A wallet (MetaMask works fine) Some ETH on Base mainnet for gas (under $0.50) 5 mi…

If you've searched "PRC-20" and come away confused, you're not alone, partly because the word "Pepe" is attached to several completely different crypto projects. This explainer clears that up and walks through how tokens are actually created and traded on the Pepecoin blockchain, in plain language. Pepecoin (PEP) is not the $PEPE you're thinking of There are two well-known things called some vers…

Growth is expected to be led by public market securities, particularly U.S. equities and Treasuries.

The Pain Point Exposed by the AWS Outages June 2026 · An analysis of infrastructure concentration When a Few Cooling Units Failed, an Exchange Went Dark On the night of May 7, 2026 (around 7:48 PM US Eastern Time), nearly all trading on Coinbase stopped. The cause was neither the market nor a hack. In a single availability zone (use1-az4) of AWS us-east-1, multiple chillers failed simultaneously,…
