Tupelo enables developers to build decentralized applications using blockchain. Tupelo's ChainTree is a unique data structure in which every object is modeled independently allowing for infinite sharing. ChainTree data can be made public, private or semi-private. The API can be accessed by using Tupelo's proprietary language-focused packages.
