when will the iXXo infrastructure be open source ?

iXXo technical infrastructure contains:
-The dAppBox, a P2P client protocol connected to iXXo blockchain: The front end will be open source. There will also be an API available. (target date 2018, when stability will be reached).
The data access rules management system (which contains read access right, write access rights, delegation accesses, time-restricted accesses, ownership transfers) will be open source.
The dAppBox services, a set of web based functions to access all dAppBox features in a programmatic way, can be deployed on a custom on-demand environment for each user alongside dAppBox registration system.
-The RockEngine, a P2P privacy-preserving computation framework (allow to do computation on private data on 2 nodes for a global public result).
An API will be available as a test mode only. RockEngine will not be integrated into the early versions of iXXo blockchain and targets advanced scalable privacy-preserving features.
-The blockchain: It is a fork of Ethereum with extra features. We changed the consensus (based on POA protocol) along with the blockchain account (several "currencies" are allowed on each user account).
The protocol will be open sourced early 2019.
-The blockchain management toolkit. We deploy and scale our blockchain using Kubernetes, and autoscale the dAppBox network using Helm.
All our infrastructure code (the links between our cloud management platform, currently Azure, and our public network) is to remain private.
The blockchain consensus and modified solidity engine will be open source allowing any business our developer to verify the legitimacy of transactions on iXXo. Anyone can run an iXXo node and check the blockchain transactions. All access rights between dAppBoxes are coded in open source smart contracts (by definition, a smart contract is open source) and access rights management and audited changes will all remain public
