At issue, is that they were initially used in a narrow context (usually to describe bitcoin’s blockchain), and are now being interpreted more generically for other blockchains, in cases where they may no longer apply. In this post, I hope to untangle some of these common misconceptions. Theme: Blockchains are secure Writing data Bitcoin has specific security features for writing data due to the burden of proof-of-work consensus. That is, in order to add blocks of transactions to the blockchain, you have to validate all the transactions within the block (easy) and then perform repeated calculations (called hashing) to find a magic number that makes your block valid and acceptable to the other participants according to the rules of the network (easy, but computationally expensive, therefore …

They used a microchip developed by Dangerous Things, which stores 888 bytes of data, enough to hold up to 26 Bitcoin private keys. The two developed the software that takes the NFC scan and transmits it to their online bitcoin wallet portal, providing a quick confirmation. “We are here to try to expand the frontiers of bio-functionality,” Tara reports to Vice’s Motherboard. “We started with bitcoins as a tribute of the revolution on the internet, and we believe in have the ownership of our data.
