Coming from a logistics background, coordinating tracability data is painful within a company , even with help of ERP like SAP. But when you need tracability across an industry , it becomes almost impossible. I had professional experience in an industry where we had to go to the plants to ensure rolls of paper certified from suppliers using responsibly-managed forests were physically separated from the non-certified…

wouldn't a simple system of signatures certified by a certificate authority (like for the web) solve this problem in a much more direct way?

It's really not hard to think of useful applications for blockchain. The problem HN has with blockchain is that a lot of HN users are the problem which decentralization solves. The basic startup monetization strategies these days revolve around centralizing user data and then collecting rent (usually in the form of ads) or centralizing transactions and then collecting a percentage. Decentralization is the antithesis…

I think the fundamental assumption is that "Satoshi invented a useful solution to decentralized consensus". What people don't realize is that Satoshi's solution only works if two assumptions hold true: 1. Mining is decentralized: If mining is centralized than relying on proof-of-work for consensus is waste since the centralized entity controls the blockchain anyway. 2. Consensus rules don't change: If you see the thr…

But one of the biggest selling points of Bitcoin itself was mathematically limited supply. A new cryptocurrency appearing every day fundamentally undermines the value proposition. Blockchain may have value as a decentralized ledger in other areas, but “lots of blockchain based currencies” aren’t really one of them since it’s self-sabotaging.
