If you've built on Ethereum and you're now exploring Solana, the first thing that will trip you up isn't the language (Rust takes getting used to, but it's learnable). It's the mental model. Solana separates code from state at a fundamental level — and once you internalize that, everything else clicks. This article walks through the core differences in how both chains store data, why Solana's des…

Some fighters will receive bonuses in ‘stablecoins’ issued by Trump family business World Liberty Financial The Ultimate Fighting Championship (UFC) announced on Friday that it will pay bonuses to fighters in a form of cryptocurrency issued by Trump family business World Liberty Financial at the heavily publicized White House mixed martial arts event on Sunday. The development connects the Trump …

Title: The agent economy added two rails and lost most of its volume this week. Nobody added settlement. Tags: mcp, ai, cryptocurrency, blockchain This is our weekly recap from building Hashlock in public. We try to read every agent-economy announcement of the week and ask one question of each: at the moment a trade actually clears, which layer finishes it? This week the answers lined up unusuall…

If you come from Web2, you probably think of a token as a number in a database that moves around when people transact. On Solana, the original SPL Token program is exactly that. Token-2022 is the upgrade — and it lets you bolt behaviors directly onto the mint itself, the way you would add middleware to a payment pipeline, except the middleware lives inside the asset and cannot be bypassed. This w…

In extreme network censorship environments, when all conventional VPN protocols (such as WireGuard, VLESS, or Shadowsocks) are accurately identified and blocked, DNS tunneling often becomes the "last resort." Today, we're featuring MasterDnsVPN (GitHub 6.1k Stars), an open-source project that pushes this classic technique to a new level. It not only excels in stability but also completely outshin…

The trade-through rule is seen as one of the biggest barriers to tokenized U.S. equities trading in DeFi.

The digital depositary receipts use blockchain infrastructure operated by SIX to tokenize private shares.

The fund may seek to use blockchain technology to record share ownership in the future.

Coming from a Web2 background, I originally thought about tokens in a very simple way. A token was something you create, mint, and transfer, while anything more interesting, like fees, restrictions, or identity, would probably live in the backend. Working through Solana token exercises changed that assumption for me. Over the past few days, I built several kinds of tokens on Solana devnet: a basi…

Navigating the tech space today often feels like walking a tightrope between two extremes: massive corporate monopolies holding all the keys, and idealistic local projects trying to build everything from scratch. But this doesn't have to be an "Us vs. Corporations" battle. We don’t need to completely eliminate corporate tools; we need to leverage them. The real pragmatic goal is to use localized,…

Lately, some Bitcoin users have been pushing to forbid OP_IF in P2TR leaf scripts to prevent use of the inscription envelope. More recently, I have seen a new claim to support that endeavor: that the ...

Before this week, NFTs on Solana weren't new to me. I've previously worked with Programmable NFTs ( pNFTs ) and even built projects that integrate them. However, most of my experience was centered around the Metaplex ecosystem, so I tended to think about NFTs through that lens. What surprised me during this learning arc was discovering how much can be built directly with Token Extensions. By crea…

In August 2022, the Nomad bridge was drained of $190 million over eight hours. The on-chain signal was there from the very first transaction. Nobody caught it in time. We built Heimdall to change that. The Problem With Bridge Security Cross-chain bridges are the most hacked infrastructure in crypto. Ronin: $625M. Wormhole: $320M. Nomad: $190M. The pattern repeats because bridges hold enormous amo…

The Initiative for CryptoCurrencies and Contracts (IC3) analyzes how the convergence of two emerging technologies, crypto and AI, can help or harm users in a new overview titled Crypto x AI, AI x Crypto: A Survey.

This work proposes StakeNote, a distributed ledger protocol that combines Proof-of-Stake (PoS) with privacy and anonymity preserving payments. The protocol combines Ouroboros Praos, a provably secure PoS protocol, with CryptoNote, a privacy-preserving payment system based on ring signatures which has been widely used in practice. We prove that StakeNote inherits the security guarantees of Ourobor…

ERC20, ERC721, and ERC1155 were brilliant inventions. They gave Ethereum a shared language for digital assets. Wallets could recognize tokens. Marketplaces could list NFTs. Indexers could track balances and ownership. Apps could integrate with assets they had never seen before without every team inventing its own custom logic. That was a foundational step for the EVM ecosystem. But here is the un…

Transitioning from a traditional Web2 background into the blockchain space can feel daunting, but completing days 29 through 33 of the Solana 100 Days Challenge completely shifted my perspective. On Solana, digital assets are deployed using the Solana Program Library (SPL). These can be fungible assets (like standard utility tokens or stablecoins) or non-fungible tokens (NFTs). As a software engi…

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 …
