    DAOMERGE is the newest brand revolving around the idea of providing a smooth, secure and efficient experience at a cheapest cost. Daomerge is a layer 2 blockchain network that has successfully overcome the Blockchain Trilemma. The Blockchain Trilemma refers to the balancing act amongst security, scalability and decentralization. In simple words, if the network is centralized, it makes it highly scalable, yet less secure. On the other hand, if blockchain networks are decentralized and safe, the scalability reduces, which means higher transaction fees and a slower process. That's the whole conundrum. At Daomerge , we have solved the Scalability Trilemma by introducing the Proof of Stake (PoS) system. PoS is focused on improving the Consensus Protocol. The PoS consensus mechan...
