Hellenic coin security

1)Hellenic Coin transactions don’t require you to give up any secret information. Instead, they use two keys: a public key, and a private one. Anyone can see the public key (which is actually your Hellenic Coin address), but your private key is secret. When you send a Hellenic Coin,

you ‘sign’ the transaction by combining your public and private keys together, and applying a mathematical function to them. This creates a certificate that proves the transaction came from you. As long as you don’t publish your private key for everyone to see, you’re safe.

2)Hellenic Coin is entirely decentralized, it's a relatively private currency. It is transparent – thanks to the blockchain, everyone knows how much a particular Hellenic Coin address holds in transactions. They know where those transactions came from,and where they’re sent. Unlike conventional bank accounts, no one knows who holds a particular Hellenic Coin address. It’s like having a clear plastic wallet with no visible owner. Everyone can look inside it, but no one knows whose it is. When you send a transaction, it is digitally signed, and secure. An unknown miner will verify it, and then the transaction is completed. The merchant need not even know who you are, unless you’ve arranged to tell them.

3)Once Hellenic Coins have been sent, they're gone. A person who has sent Hellenic Coins cannot try to retrieve them without the recipient's consent. This makes it difficult to commit the type of fraud we typically see with credit cards in which people make a purchase and then contact the credit card company to make a chargeback, effectively reversing the transaction.
