【Abstract】Blockchain is being used in various global supply chains with its ever-increasing maturity and popularity. However, in the presence of subjective information that does not have a digital footprint, blockchain application is a grey area. This is due to the difficulty in confirming the authenticity or legitimacy of information before achieving consensus on it using existing mechanisms such as Proof of Work (PoW), Proof of Authority (PoA) or Proof of Stake (PoS). In this paper, we attempt to address this issue. Specifically, we propose the Proof by Earnestness (PoE) consensus mechanism that determines the subjective information's truthfulness before further processing and formalising in blockchains. We consider supply chain risk management (SCRM) as our application area due to the vast amount of available subjective information. (C) 2022 Elsevier B.V. All rights reserved.

【标题】用诚意证明（PoE）来确定区块链中主观信息的真实性——在供应链风险管理中的应用
【摘要】区块链正被用于各种全球供应链，其日益成熟和普及。然而，在存在没有数字足迹的主观信息的情况下，区块链应用是一个灰色地带。这是因为在使用工作证明 (PoW)、权威证明 (PoA) 或权益证明 (PoS) 等现有机制达成共识之前，很难确认信息的真实性或合法性。在本文中，我们试图解决这个问题。具体来说，我们提出了认真证明（PoE）共识机制，该机制在区块链中进一步处理和形式化之前确定主观信息的真实性。由于大量可用的主观信息，我们将供应链风险管理 (SCRM) 视为我们的应用领域。 (C) 2022 Elsevier B.V. 保留所有权利。
