Full Changelog: bifrost-v0.9.72...bifrost-v0.9.74

Notice! This upgrade will bring about major changes that are closely related to community users:

Considering the current market conditions and the price of BNC, the transaction fee on the Bifrost chain has been kept at a very low level. This poses some problems:

• Affects the security of the Bifrost network
• Not conducive to the orderly operation of the Bifrost economic model
• It is not conducive to the full flow and value expression of BNC token

In order to solve these problems, we have increased the transaction fees for operations on the Bifrost chain in this upgrade. The case is as follows:

*Due to the complexity of the calculation of the actual transaction fee on the chain, the actual estimated value above is only for reference and not an exact value

Based on the complexity of the transaction, the transaction fee change multiple of different transactions will be somewhat different, but the overall change rate is generally between 40x - 60x.
