Overview over blockchain contents
As an avid reader, you know my arguments that neither NFT nor smart contracts live up to their promises, and that the blockchain underneath is also more fragile and has a worse cost-benefit ratio than most believe. Similarly, I also claim the same for the metaverses built on top of them all. And that the…
Bureaucracy and inefficiency are frowned upon, often rightly so. But they also have their good sides: Properly applied, they ensure reliability and legal certainty. Blockchain disciples want to “improve” bureaucracy-ridden processes, but achieve the opposite. Two examples:
Yesterday, the U.S. Securities and Exchange Commission (SEC) released its indictment against Sam Bankman-Fried. It details the financial entanglements of FTX, Alameda Research and more than a hundred other companies and individuals. We have tried to disentangle these allegations somewhat for you.
Drew Austin raises an important question in Wired: How should we deal with our accumulated personal data? How can we get from randomly hoarding to selection and preservation? And why does his proposed solution of Web3 not work out? A few analytical thoughts.
“NFT” is currently on everyone’s lips again, and not only because of Pro Senectute. But what is actually behind the full-bodied promises of the NFT advocates? For more insights on NFTs and the entire blockchain ecosystem, click here. You can also read this text in German 🇩🇪. “NFT” stands for “Non-Fungible Token” and is being…
The question of using digital money in the event of a network outage comes up again and again. Here is an overview of the options and their pros and cons.
Susanna Petrin closes her NFT experiment with a dystopia of life after we destroyed our environment: Admiring our NFTs while strolling through the metaverse. I hope we can avert both.
Yesterday, Rene Jan Veldwijk posted a blockchain decision flowchart he had previously used in a presentation.
People often try to claim blockchain use cases without much deliberation. Here is a condensed, quotable version of «Hitchhiker’s Guide to the Blockchain» and «Data lifecycle questions, not only for Blockchains».
Web3 claims to be the only way to save us from commercial entities defining what we can see and what not. Yet, it does exactly this: It results in commercialized entities defining what we can see and what not.
In any data-centric applications, understanding the data lifecycle (also as part of the product lifecycle) is important, especially when trust or traceability are also goals. If Blockchain should play a role, then the requirements associated with the data lifecycle can even become a decisive factor: Either adapt the data model or the processes, or, if…
Here are some attempts to compare Proof of History (PoH), as used by the Solana blockchain, with Proof of Work (PoW). Comparisons to real-world activities, such as dice rolling or outer-space rubber-stamp throwing are also included.
