It's not decentralized if there's a trusted oracle.<p>So many schemes in the "blockchain" space fail to understand the core problem Bitcoin solves. Bitcoin solves trust. You can transact Bitcoin with anybody and you don't have to trust a single person, even the sending party. If someone sends you Bitcoins and the transaction is 6+ confirmations deep in the blockchain, you can be certain that you own those Bitcoins and nobody else can take them from you without your private keys. Not a bank, not a government, not a miner, not a "core dev", not a full node operator. The only necessary assumption is that 51% of the hash power is not conspiring against you.<p>Whenever you see a new "blockchain" scheme coming out, ask yourself who you need to trust for it to work. If the answer is not "nobody", then it is not worth any more of your time.
