At a dinner party the other night, a very accomplished business person told a story about how he and his wife were certain that their devices were listening to their conversations. “I was talking to my wife about a pair of designer shoes that she wanted to purchase, and not 10 minutes later while she was doing some online research for work, she saw an ad for that exact pair of shoes. She hadn’t searched for the shoes; the ad just appeared. Clearly, our computers or our phones are listening.” Some people nodded in agreement, and others began to chime in. Continue Reading →
Metacademy
I’m thrilled to announce the public beta launch of Metacademy: a free-to-use, risk-free, hands-on website that will teach you about blockchain, cryptocurrency, NFTs, smart contracts, Web3, and other associated technologies.

MetaMask Mac Attack

There is a new phishing scheme targeting MetaMask users on Apple devices. You’ll get a phone call with a legit-looking Apple caller ID. The caller will ask you to call them back so that you “know” the call is real (which it isn’t), at which point the scammer will ask you for a code that is being sent to your phone.

Transactions are viewable by anyone (including you and me), so let's do a little exploring and see who spent $337,500 (1 ETH = $2,500 at the time) to get their Bored Ape. Continue Reading →

Axie Hack is Mindblowing

Axie Infinity is the most popular play-to-earn game. It is one of the best current examples of how you might combine Web2 and Web3 concepts to push the envelope. NFT|LA, a massive event about – you guessed it – NFTs opened yesterday, and I had the pleasure of moderating the opening fireside keynote with The Continue Reading →
Thinking
Part of the power and promise of Web 3.0 is the concept of decentralization, the ability to transact without the need for a central authority or an intermediary such as a bank or centralized exchange. While the idea of decentralization is quite easy to understand, the devil is in the details. Continue Reading →

Ukraine Using Telegram

As Russian troops surround Kyiv, millions of Ukrainians have relied on Telegram to receive government information. Why Telegram? There was an official Ukrainian COVID information Telegram channel @COVID19_Ukraine, and when war broke out, its members voted to have the channel refocus on real-time war news. The channel is now called @UkraineNOW. Continue Reading →
