Hello JamescrypTrader,
To answer your question regarding which coin is using the easiest implementation of the blockchain technology, we suggest you take a look at the Bitcoin protocol. The whitepaper created by Satoshi Nakamoto is quite simple and easy to understand, especially in comparisson to other recent whitepapers of alt coins. This document can be found
here.
Every coin after Bitcoin, has a unique selling point or goal for their coin. These aspects usually make their chains more complex. For example, the blockchain used in privacy coins is not very simple to understand because of the anonymity factor they have implemented on their network. Other coins like Ethereum, are not just a blockchain, but it function as complex platform that enables developers to create smart contracts or launch ICO's. Aspects like these add mutliple layers of complexity.
If we would have to name an alt coin specifically, we would have to say Dogecoin. This is because the development of this coin has been stopped already meaning that it didn't have mayor modifications to their protocol since its initiation. You can check their GitHub repository
here, to learn more about this coin and the technical specifications.
With kind regards,
The Anycoin Direct team
