<p>In the era of the digital economy, the protection of digital intellectual property is an important issue. At present, blockchain is widely used in the field of intellectual property protection. The market cap of NFT achieved tens of billions of dollars in a short period of time. Due to the lack of transaction openness, users are far less enthusiastic about the consortium blockchain-based intellectual property trading market. However, NFT is also plagued by a large number of pirated works. Existing methods are far from meeting the requirements of safe and efficient intellectual property protection tasks. To address this issue, we propose B2IPTS, a novel framework that integrates the advantages of consortium blockchain and cryptocurrency in the field of intellectual property protection. Our framework provides efficient ways to register intellectual property and execute transactions across blockchains. The property owners and property purchasers can exchange assets across heterogeneous blockchains without relying on a trusted intermediary. We use blockchain and cryptography to achieve three characteristics: (i) efficiency-fast on-chain certificate storage, (ii) versatility-compatibility with most blockchain structures, and (iii) atomicity of transactions-after a successful payment, the purchaser will definitely obtain the property. B2IPTS is designed as a decentralized system framework based on the consortium blockchain, and its primary functions rely on smart contracts.</p>
