EKO Blockchain Platform is a public blockchain service built on top of Proof of Professional Stake consensus protocol (PoPS). PoPS is designed for enterprise grade blockchain applications. The EKO Blockchain Platform is fully compatible with EVM based Solidity smart contracts. The EKO Blockchain Platform provides businesses and developers a fast and efficient way to develop and deploy blockchain applications. Taking the lessons learned from building the EchoLink service, we distill all the necessary components of making successful blockchain applications and offer these components as services. The EchoLink Core Service is built on top of the EKO Blockchain Platform. The EchoLink Core Service provides verified education, skill, and work experience information. Taking advantage of blockchain technology’s immutability and time stamp functionality, EchoLink provides users with trusted information regarding a job candidate’s education, skill, and work experience. The EKO Blockchain Platform is the foundation, on which enterprise level distributed applications, such as the EchoLink Core Service, can be successfully built and deployed with security, efficiency, and high performance.
