Giracoin News is the greatest news source regarding Cryptocurrency. Giracoin is the Swiss Cryptocurrency with the largest worldwide growth currently. Its very fast growing Cryptocurrency of the word & it will beat Bitcoin in near by time.

Giracoin connects people worldwide and allows transactions to take place in seconds regardless of borders. Independent of influence by central bank or governments, with complete transparency and security.

Using a combination of Proof of Stake and Proof of Work procedures, we make direct participation in mining possible for everyone. We use state of the art technology to do so. Our vision is to connect people around the world and to overcome borders and limits on payment instruments. Global transactions within seconds open an entirely new world of international opportunities.

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.

Transactions that are computationally impractical to reverse would protect sellers from fraud, and routine escrow mechanisms could easily be implemented to protect buyers. In this paper, we propose a solution to the double-spending problem using a peer-to-peer distributed time stamp server to generate computational proof of the chronological order of transactions. The system is secure as long as honest nodes collectively control more CPU power than any cooperating group of attacker nodes.
