If blockchain networks are to become the building blocks of the infrastructure for the future digital economy, then several challenges related to the resiliency and survivability of blockchain networks need to be addressed. The survivability of a blockchain network is influenced by the diversity of its nodes. Trustworthy device-level attestations permits nodes in a blockchain network to provide truthful evidence regarding their current configuration, operational state, keying material and other system attributes. In the current work we review the recent developments towards a standard attestation architecture and evidence conveyance protocols. We explore the applicability and benefits of a standard attestation architecture to blockchain networks. Finally, we discuss a number of open challenges related to node attestations that has arisen due to changing model of blockchain network deployments, such as the use of virtualization and containerization technologies for nodes in cloud infrastructures.

如果要使区块链网络成为未来数字经济基础设施的基础，那么就需要解决与区块链网络的弹性和可生存性相关的若干挑战。区块链网络的生存能力受其节点多样性的影响。可信赖的设备级认证允许区块链网络中的节点提供有关其当前配置，操作状态，密钥材料和其他系统属性的真实证据。在当前的工作中，我们回顾了标准认证体系结构和证据传输协议的最新发展。我们探索了标准认证架构对区块链网络的适用性和优势。最后，我们讨论了由于更改区块链网络部署模型而出现的与节点认证相关的许多开放挑战，例如对云基础架构中的节点使用虚拟化和容器化技术。
