Recent years have seen the continuous evolution of technology, which has led to the definition of frameworks such as the internet of things (IoT) and Industry 4.0. These paradigms are producing enormous quantities of data every single day. These data are subject to data analysis, shared publicly or kept secret. Traditionally, this task was carried out using databases. With the advent of Blockchain and other distributed ledger technologies (DLTs), instead, these data have a new way of being stored and shared (or kept private). The last actor role in this play is acted by quantum computers, since sufficiently large quantum computers are expected to seriously threaten the security and integrity of DLTs thanks to their totally different way of representing information. This paper aims to investigate the real threats for blockchain due to quantum computing and review post-quantum DLT solutions for traceability applications.

切割区块链的量子钳子

近年来，随着技术的不断发展，物联网 (IoT) 和工业 4.0 等框架得以定义。这些范式每天都在产生大量数据。这些数据受数据分析、公开共享或保密。传统上，这项任务是使用数据库来执行的。相反，随着区块链和其他分布式账本技术 (DLT) 的出现，这些数据有了一种新的存储和共享（或保密）方式。该剧中的最后一个角色是由量子计算机扮演的，因为足够大的量子计算机由于其完全不同的信息表示方式，预计将严重威胁 DLT 的安全性和完整性。
