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.
Gulden is a second-generation peer-to-peer cryptocurrency which was created to provide a secure, simple and fast method of performing financial transactions between private individuals, customers & service providers and also corporate entities. Like many recent cryptocurrencies, the primary design criteria were to improve the security and usability of the currency and its underlying transaction authorisation technology (when compared to the original cryptocurrency - Bitcoin). The purpose of these changes was to simplify use and increase its adoption as a convenient, cheap and safe form of payment. The original initiative for this currency came from Rijk Plasman with the first working implementation released on the 4th April 2014. Initially called the “Gulden coin”, this was subsequently abbreviated in October 2015 to “Gulden”. The name Gulden comes from the German and Dutch term for “gold coin” and is the Dutch name of the Dutch guilder, the pre-euro currency of the Netherlands. Gulden Coin is the currency that enables the user to pay safely, conveniently and quickly. Moreover, it is a lucrative investment opportunity at the moment, considering that since entering the market in 2016 the developers have increased to a market capital of 39,883,259 USD with about 800,000 USD. The model of making cryptocurrencies accessible to ordinary consumers in the future holds enormous potential in the fintech sector.
