4. Vulnerability Analysis

The Uninitialized Local Variables in Storage (Vulnerability Analysis Series Phase 7) Chinese version has been published. The event of “seat occupation” reminders us of the relevant problem in smart contracts vulnerability, so this article we wrote serves the purpose of analyzing the uninitialized local variables in storage and accordingly putting forward solutions. Stay tuned to our media for English version.

Chengdu LianAn Technology Company is about to restate the following two points in terms of the development and use of smart contracts.

Firstly, the spirit of contracts development must be honored. It is indispensable to adhere to the specification and make a comprehensive planning in successfully applying blockchain, thus the emerging technology can make a progress with a steady pace.

Secondly, once one realized that a contract is a long-premeditated trick, he or she must beware of the sugar-coated bullets from contracts founders. Never relax vigilance against evil-doers.

Recently, EOS community is trying to find way out because EOS developers found a vulnerability by which malicious contracts get access to greatly sucking users’ storage resources. We translated and reposted an article published By CCN, which welcome everybody to read it in the official account of LianAn.
