Introducing RandX

Public blockchains bring revolutionary properties, such as decentralised consensus and immutability to reality. However, they do not scale well and for good reasons. Certain trade-offs are made in scalability to ensure network security and to maintain a decentralised design.

Solving scalability is a necessary measure for adoption. There are many interesting projects in this space such as Bitcoin's Lightning Network and Ethereum's Raiden Network. We decided to explore a solution to second layer scaling by developing RandX, a digital financial platform built using smart contracts on the Ethereum Public Network.

RandX is an ongoing research project to bring fast and low cost transactions to the Ethereum space in a user friendly digital wallet while maintaining the underlying decentralised and trustless nature of the blockchain. Visit randx.io if you are interested in exploring this technology and its potential benefits for you and your company.
