Just as we don't pay much attention to the critical infrastructure that powers our digital world and exists just out of sight from the Automated Clearing House (ACH), which undergirds our financial system, to the undersea cables that enable the Internet to be globally useful, blockchain is likely to change our lives in ways that will eventually be invisible. In the sharing economy, we have traditionally just used existing infrastructure and built platforms and services on top of it. Considering that those undersea cables are owned by private companies with their own motives and that the locations of ACH data centers are heavily classified, there is a lot to be desired in terms of transparency, resilience, and independence from self-interested third parties. That's where open-source, decentralized infrastructure of the blockchain for the sharing economy offers much promise and potential. Origin ... is working to reduce the cost, difficulty, and barriers to entry for building marketplaces, enabling people to build truly peer-to-peer marketplaces on the blockchain. In creating this kind of decentralized underpinning, blockchains offer communities alternatives to one-size-fits all solutions and economies of scale. Another crucial part of the sharing economy infrastructure is financial infrastructure. Consider the two billion unbanked and underbanked adults around the world. Can blockchain benefit them as well? WeTrust is one of the blockchain startups working to do this, and has already put out a lending circle product.
