Abstract

The invention discloses a method, a client, an alliance chain and a system for realizing a light wallet mechanism in the alliance chain. The method belongs to the field of block chains, and comprisesthe following steps: a wallet client running a trusted execution environment initiates a transaction to an alliance chain in a common execution environment, so that a receiving node stores the transaction consensus into the alliance chain and a local Merkel tree; after the wallet client is switched to the trusted execution environment, if the root node hash value of the Merkel tree stored locallyis not equal to the root node hash value of the Merkel tree with latest transaction information recorded in the alliance chain, the local storage is updated until the root node hash value is equal tothe root node hash value of the Merkel tree; and a verification path of the transaction is acquired in the Merkel tree from the alliance chain to recalculate a root node hash value of the Merkel tree,and the root node hash value is compared with the root node hash value of the Merkel tree locally stored in the wallet client to determine whether the transaction is successful or failed. According to the invention, the light wallet mechanism can be realized in the alliance chain, and the security of the light wallet mechanism is improved.

Description

technical field [0001] The invention belongs to the field of block chains, and more specifically relates to a method for realizing a light wallet mechanism in an alliance chain, a client, an alliance chain and a system. Background technique [0002] After several years of development, digital currency has become more and more popular in the field of financial technology, and its total market value reached 800 billion US dollars in January 2018 (of which Bitcoin accounted for more than 30%). Unlike traditional wallets, digital wallets used to manage digital currency are more dependent on the wallet's private key, so the security of the wallet's private key is becoming more and more important. [0003] There are many types of digital wallets currently available. Among them, hardware digital wallets are highly secure, but users need to carry additional dedicated physical devices, so it is very inconvenient to use; software digital wallets are easy to use, but their security can...
