Bandcoin：使用智能合约自动化移动网络带宽漫游协议
Bandcoin: Using Smart Contracts to Automate Mobile Network Bandwidth Roaming Agreements
摘要：
我们提出了一种新的方式，使用基于区块链的智能合约在运营商、服务提供商和消费者之间共享移动网络中的许可频谱带宽容量。我们讨论了合同中的基本构建块以及各种扩展，以支持更高级的功能，如批量购买，未来预订和各种拍卖机制。此外，我们还演示了如何使用开源的许可企业区块链Hyperledger Sawtooth来实现该系统。我们表明，我们的智能合约实现可以提高区块链交易性能，与串行交易相比大约提高了四个数量级，与并行交易相比提高了一个数量级，使用PKI驱动的批量购买移动访问权限，为完全自动化，高效和细粒度的漫游协议铺平了道路。
英文摘要：
We propose a new way to share licensed spectrum bandwidth capacity in mobile networks between operators, service providers and consumers using blockchain-based smart contracts. We discuss the foundational building blocks in the contract as well as various extensions to support more advanced features such as bulk purchases, future reservations, and various auction mechanisms. Furthermore, we demonstrate how the system can be implemented with an open-source, permissioned Enterprise blockchain, Hyperledger Sawtooth. We show that our smart contract implementation can improve blockchain transaction performance, by approximately four orders of magnitude compared to serial transactions and one order of magnitude compared to parallell transactions, using PKI-driven bulk purchases of mobile access grants, paving the way for fully automated, efficient, and fine-grained roaming agreements.
