Zilliqa is a blockchain platform which focuses on solving numerous problems when scaling public blockchains. With Zilliqa’s netowrk, the number of transactions increases at a linear rate to the number of nodes.

This is important because as nodes increase, so will its ability to handle high transaction volume. Ziliqa has successfully run a test on their network where they were able to achieve 1,200 transactions with only 2,400 nodes. This is proof of their ability to achieve their goals.
Zilliqa was also the first network to successfully integrate “sharding” into a public blockchain. This is useful when improving the rate of scalability, bandwidth, and performance in blockchains. Sharding splits nodes in smaller nodes, “shards”, which then can be used to conduct micro-transactions in each block within the blockchain. This technology also makes it more energy efficient to mine.

Decred

Decred or “decentralized credit”, is a digital currency that uses a community based governance model to determine the future of it’s blockchain protocol. The core mission of this project is to solve issues with blockchain governance. Bitcoin has had many problems with the community not being able to agree upon protocol changes, such as block sizing and hard/soft forks in the blockchain. Decred employs a hybrid of Proof-of-Work (PoW) and Proof-of-Stake (PoS) mining to decentralize the decision making process. The team behind Decred is made up of developers who volunteer their time and choose to remain pseudo-anonymous. This is intended for a decentralized implication in their image, but not fully understood. Community members can still interact with them via telegram, reddit, etc.
