This week, we’re paddling into an exciting conversation. It’s initiated by Ethereum’s co-founder, Vitalik...
Zero-Knowledge Proofs (ZKPs) are the hottest new technology in blockchain — and for good reason. The ability to prove something while not having to share the available information behind it is just immensely powerful. This is particularly true as it relates to digital identity. Think about how you’d prove you’re...
Zero-knowledge proofs have proven to be an essential instrument for ensuring privacy in digital identity systems. These new systems allow individuals to verify their identity without exposing sensitive private data. Now, as concerns over data privacy and government surveillance mount, these solutions are increasingly becoming an enticing prospect. Though zero-knowledge...
As we continue developing this exciting new world of blockchain-based digital identity, privacy will always be our most important priority. Taking this idea further, Vitalik Buterin, co-founder of Ethereum, has proposed ‘pluralistic IDs. This proposal would be a big step toward ensuring privacy in any future digital identity system. This...
As Ethereum co-founder Vitalik Buterin recently explained, ZK technology has exciting possibilities for verifying identity. He pointed out the dangers posed by its implementation. His analysis comes amid growing interest in global digital identity projects, such as the World Project, which utilize ZK-proofs to verify user data without exposing the...
Hello blockchain and crypto enthusiasts! Jason back again, bringing you even more dank insights from Calloutcoin.com. Today, we're diving deep into a critical area for the future of decentralized physical infrastructure networks (DePINs): security. As DePINs expand to maintain more real-world infrastructure, making sure their networks are cyber threats robust...
The dirty little secret about DePINs though? They’re sitting ducks. All that new decentralized infrastructure, humming away, is ripe for attack as anyone can spoof an admin account and cause chaos. We’re not talking about just theoretical doomsday scenarios – but real-world consequences like compromised energy grids, hijacked sensor networks...
Remember the early days of the internet? Wild West, right? That’s how DeFi seemed just a few years ago. “Rug pulls” started entering the broader crypto lexicon. That’s starting to change and for the better. We know regulation can be a buzzkill but it’s the only way to find out...
Humanity Protocol opened the doors to its fast and secure decentralized ID service on June 26. The H token saw its value explode following a successful “Fairdrop” to early users and supporters. The H token, meanwhile, has seen a 40% price surge over the last 24 hours. The flood, of...
The crypto world loves a good narrative, and Humanity Protocol's H token is dripping with one: a fairdrop revolution. Yet the promise is unmistakable. We will fight to reclaim airdrops from the arms of the bot armies and restore them to actual, live human beings. The method? Palm scans. Yes,...
A billion-dollar valuation for the ability to palm scan? No joke. While everyone’s chasing the next crypto unicorn, I can’t shake the feeling we're blindly galloping towards a future where our bodies are the ultimate key – and the ultimate target. Humanity Protocol’s H token has skyrocketed, partially fueled by...
It’s that same sort of exuberance you felt when you first heard about the metaverse. The fulfillment of digital utopia, being in touch with everyone on planet Earth through expansive online metaverses, creating prosperous virtual societies? It sounded revolutionary. Now, look at Horizon Worlds. Clunky avatars, digital tumbleweeds, and a...
Zuckerberg wants AGI. Personal superintelligence, he calls it. An AI that essentially runs your life. Sounds convenient, right? Maybe. But let's be brutally honest: entrusting the keys to your existence to a single, centralized entity – especially one with Zuckerberg's track record – is a recipe for disaster. Well, it’s...
Just as Mark Zuckerberg made headlines with a big pivot to the now overly-hyped Metaverse, he’s undertaking another big pivot. He’s recently been exploring the thrilling worlds of AI and AGI (Artificial General Intelligence). After the hype and billions of dollars, Meta’s Metaverse projects—especially Horizon Worlds—have found difficulty in attracting...
