Liquid Alpha
A system that dynamically adjusts how quickly bonds between validators and miners change. It uses per-miner alpha values based on consensus to reward validators who evaluate independently and make copying less profitable.
Liquid Alpha controls the rate at which bonds change by giving each miner its own alpha value. This value adjusts dynamically based on how much validators agree about that miner's performance. Without it all bonds change at a single fixed rate. With liquid alpha, these rates range between a low value (default 0.7) and a high value (default 0.9), though subnet owners can customize these within certain limits.
When a validator's weight and bond for a miner are close to consensus , alpha is pushed toward the high end (making bonds change faster). When they diverge from consensus, alpha drops toward the low end (bonds change slower).
Bonds track the relationship between validators and miners over time. Every validator-miner pair has its own bond value, updated each time Yuma Consensus runs. The update blends the validator's current weight with the existing bond using an exponential moving average (the alpha value controls how much weight goes to the new score versus the historical bond).
Strong bonds lead to higher dividends. When a validator consistently scores a miner well, their bond grows stronger, increasing the share of ALPHA dividends that validator earns from that miner's performance.
Alpha controls how fast bonds change. Think of it like a speed dial for trust-building:
- High alpha (default 0.9): bonds respond quickly to new weights
- Low alpha (default 0.7): bonds change more slowly, favoring historical scores
Each miner gets its own alpha value based on consensus. Miners with strong consensus alignment get higher alpha values, while miners where scores diverge from consensus get lower ones.
CLEARING UP "ALPHA" CONFUSION
This alpha value related to bond growth is not the same as the subnet token commonly referred to as "ALPHA". They share the name but are entirely separate concepts.
Liquid Alpha works alongside commit reveal to discourage weight copying . Commit reveal hides weights so copiers must use outdated information. While with Liquid Alpha because bonds accumulate over time through an exponential moving average, a copier starting from zero bonds cannot instantly match the dividend share of a validator who has been honestly scoring miners for many epochs.
Together, these mechanisms ensure that independent scoring remains more profitable than copying.
