There is an argument that if the Proof-of-Work (PoW) mechanism is removed from the Bitcoin network or if the puzzle does not have a sufficient level of difficulty proportional to the computing power of the network, the chaining of transact… Continue reading Is PoW an indispensable component in blockchain? [closed]
At this point the average Hackaday reader is likely familiar with so-called “Proof of Work” (PoW) cryptocurrencies, such as Bitcoin, Ethereum, and Dogecoin. In the most basic of terms, these …read more Continue reading What’s Chia, and Why is it Eating all the Hard Drives?
Introduction to blockchain consensus Blockchain systems are a collection of decentralized nodes that maintain a shared digital ledger. Without a centralized authority, the blockchain network needs some way to determine the “official” version of each bl… Continue reading Proof of Work
When I began programming microcontrollers in 2003, I had picked up the Atmel STK-500 and learned assembler for their ATtiny and ATmega lines. At the time I thought it was great – the emulator and development boards were good, and I could add a microcontroller permanently to a project for a dollar. Then the ESP8266 came out.
I was pretty blown away by its features, switched platforms, except for timing-sensitive applications, and it’s been my chip of choice for a few years. A short while ago, a friend gave me an ESP32, the much faster, dual core version of the …read more
