Hive Coin is a cryptocurrency, with the new blockchain technology and smart contracts, companies no longer need centralized intermediaries for transactions or financing. The blockchain grants absolute transparency, integrity and immutability of the data stored in the system. Hive coins are used to make demands on factoring companies, who can then compensate them. This process uses the blockchain, which offers a high level of security for all transactions. All seller and borrower data is cryptographically secured in this system.
Boolberry is a cryptocurrency based on CryptoNote technology. Boolberry's major benefit is to provide much stronger privacy to both the senders and receivers of transactions. The destination of a transaction can only be determined by its real recipient and transactions cannot be linked to a single sender. Each transaction could have many equally possible senders, and an attacker cannot determine which one it was. There is an aliasing facility built into the blockchain so that people or programs can send money to, for example, '@zoidberg' instead of a long address.
