I want to develop a proprietary service for my customers. Essentially, it's going to be a stripped-down version of blockchain. I need someone who is knows blockchain inside out - to the point where theyre not helplessly enamoured by it. If you know what you're doing, this is a walk in the park. If you're wrapped up in your crypto bubble, stay there, I have no use for you

I normally suggest some kind of hybrid solution for most of my customers. I dont think everything needs to be decentralized and the technology isnt really ready for this anyway. What kind of project did you have in mind?

Hey there, I have vast experience with crypto currencies and that includes PoW, PoS and MN based coins. I've done work that includes not only forking a bunch of coins but also fixing technical stuff like chain splits, consensus updates and so on.. I understand the underlying technology and can probably help you - just drop me a message so we can talk about the details ! price is negotiable depending on your needs but that applies both way :)
