Comparison of projects Tezos and Helium

Tezos is self amending decentralized dApp platform. Tezos was launched in 2014 but has it's mainnet in 2018. Though this project is similar to ethereum network in nature because the developers can write dapp on it's smart chain as ethereum but what distinguish it is that it doesnt need to fork before amend any protocols, what the system just need is the majority vote from those who supported a certain change. It ensures the necessary supervision of the needs that may arise over time, not through hard forks, but through the decisions of the digital society. The protocol was developed in such a way that most members of the union could easily renew themselves after the vote.
