About LZP

LZP is an inflationary token, which means there is no hard cap on the supply of LZP. The reason behind this decision lies in the primary function of LZP: to incentivize our supporters, users and liquidity providers. However, we have to address the problem of inflation.
To reduce the amount of LZP in circulation, we come up with two solutions:
- Reducing block emissions: Reducing the amount of LZP made per block
- Deflationary mechanisms: Regular token burns, and manual burns when needed
