Ethereum is holding a very strong 2nd position, but eventually, in the long term something will overtake it as a better blockchain protocol. What do you think it is going to be and why?
There are several blockchain infrastructure project which will give tough competition to ethereum blockchain such as cardano, stellar, tron, IOST, EOS, NEO and Zilliqa but not replace the 2nd position from the ethereum very soon. As huge number of the projects are using ethereum blockchain, chances for other competitors are minimum to to dethone ethereum from the 2nd rank. Out of this competitors I feel Zilliqa is the true future competitors of ethereum as they are implementing sharding technology before ethereum putting ethereum out of competition miles away. Zilliqa already have successful testnet and achieve transaction throughput of around 2000TPS without any problem using sharding technology. Zilliqa launching its mainnet on January 2019 along with huge planning and partnership for mass adoption. Zilliqa is the true competitor of ethereum and will be more scalable and secure as compare to other blockchain projects.
