Blockchain-based freelance hiring projects are popping up everywhere. In fact, you could say there are "Reining".
Rein, a bitcoin blockchain-based software project, addresses the same space as Ethlance and Chronobank, promising to fix problems related to hiring freelancers. It sees existing freelance approaches as beset by "arbitrary restrictions, unreasonable fees, and ... subpar user support".
Technically, Rein sees itself as a decentralized market and in its Github repository (repo) provides the following self-description:
Rein is a new decentralized labor market that provides a safe and easy way to earn Bitcoin and to obtain services from professionals globally. It simplifies the process of entering into a digitally-signed contract and behaving honestly to get what you want whether that's work or money. Currently, as Rein is in beta and the process requires use of a command line client. However, the software is easy to install and we appreciate your feedback to help make it easier.
Rein's repo has updates in different languages, however, the main recent contributor I believe is a David Sterry, whose Twitter profile has him in San Francisco. His repo updates and social media posts are quite active, indicating that this is a project with at least one committed developer.
One negative on Rein is its reliance on bitcoin. The bitcoin blockchain has been stumbling badly, unable to handle much volume. Users can't be sure that their transactions won't get stuck while waiting to be processed. Its aging architecture offers little to support decentralized organizations, and it's finding itself on defense against competitors such as Ethereum, DASH, and Monero.
Rein, however, has focus. It addresses the financial conflicts that arise frequently from freelance relationships.
It's also quite self-aware about the state of blockchain technology and admonishes users about potential security issues: [users are] "advised to limit use of Rein to small jobs where loss of funds or time spent would not present a significant burden"
