"A (Simplified) Blockchain Approach to Non-Coercive, Decentralized Global Governance"

The idea is to apply smart contracts on blockchain to create a universally accessible "idea-to-action marketplace" where solutions to pressing global challenges can be proposed, rapidly adopted, funded and then implemented, whereas financing is provided through a cryptocurrency:

The submission proposes a decentralized, high efficiency mechanism for collectively identifying global risks and rapidly directing practical responses to combat those risks, utilizing a blockchain platform. The platform is equally accessible to individuals, states and emerging and established Non-Governmental Organisations (NGOs). It is intended to create an idea-to-action marketplace where solutions to pressing global challenges can be proposed, rapidly adopted, funded and then implemented via smart contracts. The blockchain model lacks a standard hierarchy, with all decision making the de facto result of collective action, conducted openly. Financing is provided through a connected cryptocurrency. Once a smart contract seeking a particular action is placed on the blockchain, the request is instantly visible to any other NGO, private individual, government entity or commercial contractor, which may then undertake to fulfill some or all of the contract. The end result is a purpose-built economy which exists to identify and solve large scale problems.
