Description
Technical Field
The invention belongs to the field of block chains, and particularly relates to a user portrait construction method and system suitable for an ether house.
Background
As the largest public blockchain system with the ability to run intelligent contracts, etherhouses have attracted widespread attention in both academic and industrial sectors. Users on the Ether house can not only perform simple transfer transactions such as bitcoin, but also trigger continuous transactions by deploying intelligent contracts, thereby bringing endless imagination space for technical transformation and revolution by adopting a block chain. The ethernet house network has undergone tremendous changes since the birth of 2015, as more and more users are added to the ethernet house (increasing from thousands of people at the end of 2015 to millions of people now), correspondingly more and more accounts are created and added to the ethernet house network. Accounts can be classified into different categories according to different roles played in the blockchain ecology. For example, miners, one of the most important categories, play a major role in verifying transactions and obtaining mine-cut rewards in an ethernet network. In addition, as another broad category of exchange, a platform for exchanging a legal instrument with cryptocurrency is provided. Smart contracts make it possible to create various decentralized applications based on blockchains, which has prompted the birth of applications for tokens, games, etc.
The user portrait is originally applied in the E-commerce field, and under the background of the big data era, user information is flooded in a network, each concrete information of a user is abstracted into labels, and the labels are utilized to concretize the user image, so that targeted services are provided for the user. Constructing a user portrait on an ether house has a very profound meaning for deep understanding of a blockchain system. For example, building a user image of an account would help de-anonymize the account. In particular, if an account has been identified as being of the exchange type, it may be easier to associate it with a particular exchange. In addition, the influence of the intelligent contract on the block chain platform can be analyzed by comparing the classification components of different account categories on the ether houses and the bitcoin.
However, there is currently little work on ether house user representation construction, the most relevant being de-anonymization of accounts, which can be considered to be a broad account classification work. The existing de-anonymization work is mainly developed on bitcoin. According to different classification principles, de-anonymization methods on bitcoin can be divided into two main categories: one type of method is mainly based on a UTXO data model, and according to the classification principle, different sending accounts of one transaction can be attributed to the same user; another method is based on the behavior pattern of the user, and according to the classification principle, the one-time change account in the transaction and the sending account can belong to the same user. Because the account model is different from the UTXO model in the bit currency when the data model in the Ether mill is different from the UTXO model in the bit currency, the de-anonymization method suitable for the bit currency cannot be directly applied to the Ether mill. In general, how to construct a user portrait for an ether house is an urgent problem to be solved.
