Seven Cash as private currency or voucher is spent into circulation by trusted producers of goods and services, and by allocating internal credits to members of trade exchanges that enable them to trade with one another using a process called “credit clearing”.
The block chain is a shared public ledger on which the entire SevenCash Digit network relies. All confirmed transactions are included in the block chain. This way, SevenCash Digit wallets can calculate their spendable balance and new transactions can be verified to be spending Cash Digits that are actually owned by the spender. The integrity and the chronological order of the block chain are enforced with cryptography.
