Abstract
Authenticating Spatial Queries on Blockchain Systems
Highlights
I N recent years, blockchain systems have become popular due to the increasing success of cryptocurrencies such as Bitcoin [16] and Ethereum [5]
AUTHENTICATED DATA STRUCTURE To enable query verification for spatial data, we propose the use of Merkle R-trees (MR-trees) along with the query and verification algorithms described in [27]
In this paper we have proposed and evaluated a new approach to query verification for blockchains storing spatial information
Summary
I N recent years, blockchain systems have become popular due to the increasing success of cryptocurrencies such as Bitcoin [16] and Ethereum [5]. A blockchain is an appendonly data structure replicated among nodes in a network. Its content is organized in blocks and it is guaranteed to be immutable thanks to appropriate cryptographic mechanisms. Intended for logging monetary transactions or asset transfers, this technology has been adopted in multiple fields during the last few years, such as supply chain and logistic management, public key infrastructures, and access control, as detailed in [12]. Nowadays they are employed to record any kind of valuable information, such as ownership or identity certificates, financial accounts, and medical data. Blockchains have progressively evolved to become a platform for developing and running decentralized applications, in the form of smart contracts
