rebasing mechanism

Algorithmic stablecoins use a rebasing mechanism to expand or contract supply and keep the price near target.算法稳定币使用弹性供应机制来扩张或收缩供给，使价格保持在目标附近。

Positive rebasing increases every holder's balance proportionally, which can mask the inflationary dilution behind apparent gains.正向的弹性供应增加会按比例提高每个持有者的余额，这可能会掩盖表面收益背后的通货膨胀稀释。
