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.
CRYPTO20 is an autonomous crypto-only index fund that tracks the top 20 cryptocurrencies in the same way the S&P500 tracks the top 500 US company stocks. C20 is the fund’s token, and represents an investor’s share in the fund. Token-holders are able to liquidate the C20 token for their share of the underlying assets via the smart contract.
