Crypto and blockchain… The dog biting its own tail
Perhaps misled by Bitcoin, where in fact one (blockchain) is functional to the other (Bitcoin) and by the long legal battle between Ripple and SEC for legal and non-technical reasons, the media often lose sight of the indissolubility of the crypto-blockchain binomial .. Cryptos are essential for the blockchain to work. And without blockchain, no crypto… With crypto you pay for services on the blockchain, essentially registrations. Without crypto, either registrations are free (difficult, on the planet benefactors are scarce) or you pay by credit card. Expensive and complicated.
Then, of course, as long as the only writings on the blockchain are the crypto transactions it looks like the dog that bites its tail and it is complicated to understand the relationship between the two. The case of Bitcoin does not actually help: the BTC blockchain serves nothing but the Bitcoin crypto, and there are no new developments in sight. For now, at least, not much different for the star of this hot boreal summer, XRP, waiting for the second round with the SEC. But completely different for the Ethereum blockchain which in fact acts as a service for several other blockchains, paying with the crypto ETH. But if NFTs and smart contracts took off, the difference would emerge much more clearly. You register a smart contract or a NFT on the blockchain and pay in crypto for the service. Straightforward.
