Wanchain Mercury hard fork is coming to testnet

By Inkarias - 2019-12-14

Following the hard fork upgrade dedicated to Galaxy Consensus in late August this year, Wanchain will be undergoing another hard fork upgrade codenamed Mercury in the upcoming days. This hard fork upgrade, called Mercury, is scheduled to occur on December 16, 2019 at 0:00 UTC on the Wanchain testnet. When the Epoch ID of Galaxy Consensus reaches 18246, all Wanchain GWAN clients on the testnet which has been updated prior to that date will smoothly switch to the new Mercury branch.
In order to ensure the normal syncing process after a hard fork, all validators and all users running GWAN on Wanchain testnet should update their GWAN client to the latest version before December 16, 2019 0:00 AM UTC last delay. In order to update the GWAN client, investors can either choose between updating using scripts or a manual update. The complete details for both methods are described in this article.

Mercury features

The Mercury upgrade will bring two major features upgrade. First, the integration of Smart Contract API for Safe Random Numbers and the raise in blocks’ standard gas limit. These 2 new features/upgrades are essential for promoting Wanchain’s ecosystem, increasing Wanchain’s developer friendliness, and promoting new development path of DAPPs. Safe Random Numbers are the foundation of all blockchain based gaming DAPPs. Unpredictable and unbiased, random number serves as a safeguard for gaming DAPPs and can guarantee the fairness and trustworthiness of a game, preventing insider trading and all kinds of hacking attempts.

Finally, the blocks’ default gas limit has been increased from 4.7M to 10M, greatly improving the development experience of large scale DAPPs on Wanchain and thus increasing the potential of mass adoption for all crypto DAPPs.
