A Concept Proposal for an Ethereum, IPFS and JVM powered dApp
Mano Thanabalan

The Solidity programming language was built to address the non-deterministic way in which traditional languages such as Java compile into byte or machine specific code. The need for deterministic compilation to assembly language stems from deterministically calculating the running cost of a given Smart Contract. However, if the code, compiled byte code and variable state storage could be stored in a file in IPFS after being run and verified in a JVM, then deterministic compilation would no longer be a relevant requirement. Besides the obvious reduction in gas consumption, this design will also circumvent the Smart Contract gas limit and more complex smart contracts could be deployed.

Docker For Blockchains
Zach Ramsay

Demo of `eris` (see eris-cli); our open-source tool for orchestrating blockchain applications.
