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.
