Digital Health

Zenyai

BlockJoy

Blockchain

BlockJoy

BlockJoy allows you to deploy and run your own blockchain nodes on any infrastructure you choose. It started as a project to manager staking with friends and family. We built advanced tooling to optimize validator management for teams of two. But, due to the sheer difficulty of installing and running nodes, our little VaaS company grew crazy fast. We quickly realized that VaaS can’t work for a network because it centralizes control. We turned our platform into a SaaS tool so that anyone could launch and run their own node with full control over where and on what infrastructure it runs. Now, network operators can run their own nodes; BlockJoy just takes the headaches away.
