The main aim of ALE - is to engage the technologies of decentralized applications for project management automation. It allows performing the search of works contractors and other labor force in the legal field. That is why we have created ALE – the platform to implement project management decentralized services, with a blockchain as a central element in it. One of the main ALE features - is to support multilateral smart contracts. By means of them, or, to be exact, due to the possibility to automatically administrate the relationship of the parties, the confiding environment is guaranteed.
