Tyle miesięcy niekończących się dyskusji na wykopie, a mimo to wciąż można znaleźć takie kwiatki jak ten:
Do czego został stworzony bitcoin? Do szybkich i tanich płatności? Czy obecnie one takie są? Nie.
Otóż Bitcoin nie został stworzony ani po to by transakcje były tanie, ani po to żeby były szybkie. Może warto otworzyć samodzielnie ten słynny whitepaper chociaż raz w życiu?
Abstract. A purely peer-to-peer version of electronic cash would allow online payments to be sent directly from one party to another without going through a financial institution. Digital signatures provide part of the solution, but the main benefits are lost if a trusted third party is still required to prevent double-spending.
Commerce on the Internet has come to rely almost exclusively on financial institutions serving as trusted third parties to process electronic payments. While the system works well enough for most transactions, it still suffers from the inherent weaknesses of the trust based model. Completely non-reversible transactions are not really possible, since financial institutions cannot avoid mediating disputes. The cost of mediation increases transaction costs, limiting the minimum practical transaction size and cutting off the possibility for small casual transactions, and there is a broader cost in the loss of ability to make non-reversible payments for non-reversible services. With the possibility of reversal, the need for trust spreads. Merchants must be wary of their customers, hassling them for more information than they would otherwise need. A certain percentage of fraud is accepted as unavoidable. These costs and payment uncertainties can be avoided in person by using physical currency, but no mechanism exists to make payments over a communications channel without a trusted party.
What is needed is an electronic payment system based on cryptographic proof instead of trust, allowing any two willing parties to transact directly with each other without the need for a trusted third party.
Niesamowite, ale ani słowa o szybkich i tanich. Może tam jednak chodziło o coś innego? Dla ułatwienia wyróżniłem fragmenty. Miłej lektury.
