In this paper we survey a number of interesting applications of blockchain technology not related to cryptocurrencies. As a matter of fact, after an initial period of application to cryptocurrencies and to the financial world, blockchain technology has been successfully exploited in many other different scenarios, where its unique features allowed the definition of innovative and sometimes disruptive solutions. In particular, this paper takes into account the following application scenarios: end-to-end verifiable electronic voting, healthcare records management, identity management systems, access control systems, decentralized notary (with a focus on intellectual property protection) and supply chain management. For each of these, we firstly analyse the problem, the related requirements and the advantages the adoption of blockchain technology might bring. Then, we present a number of relevant solutions proposed in the literature both by academia and companies.

在本文中，我们调查了与加密货币无关的区块链技术的许多有趣应用。事实上，在最初应用到加密货币和金融世界之后，区块链技术已在许多其他不同情况下得到成功利用，其独特的功能允许定义创新的，有时是破坏性的解决方案。特别是，本文考虑了以下应用场景：端到端可验证的电子投票，医疗记录管理，身份管理系统，访问控制系统，分散公证人（侧重于知识产权保护）和供应链管理。对于每种情况，我们首先分析问题，采用区块链技术可能带来的相关要求和优势。然后，我们介绍了学术界和公司在文献中提出的许多相关解决方案。
