Main problems with crypto-currencies are big transaction fee, small number of simultaneous transactions compared to VISA or Mastercard, high energy consumption for mining. Everyone heard for Bitcoin, Ethereum or Litecoin.
There is one crypto project who tries to solve all those problems while keeping 100% compatibility with Ethereum. Name of project is GoChain. Project introduced concept of "Proof or reputation' where 50 big companies put their reputation on stake and do mining. They guarantee that mining will not be centralized in terms that big percent of mining facility can be in one country like on example China. That's why this crypto is more resilient on infamous 51% attack.
Blockchain comparation :
Network Speed Fees Volume
GoChain 5 seconds $0.000002 1300 tps
Bitcoin 10-60 minutes $0.07-$3.50 6 tps
Ethereum 1-14 minutes $0.01-$0.50 13 tps
It is faster, greener, more decentralized and cheaper then other crypto and current value is very low at 0.02 USD. It is 100% compatible with Ethereum and all what people can do over Ethereum can do over GoChain just faster and cheaper.
All dapps which are working on Ethereum can work on GoChain and you can use same wallets.
Leading US satellite TV provider dish and #1 LIVE streaming TV service Sling are both authorized block signers on GoChain public mainnet.
It is definitely worth a try, very promissing project which is undervalued at the moment.
