Can a cryptocurrency stabilize its own supply without a central authority?
A Decentrally Stabilized Cryptocurrency
I've been thinking about a cryptocurrency with a property I haven't seen before: a currency whose supply adjusts itself in a completely decentralized way, without any central authority or mandatory intervention.
The underlying observation is surprisingly simple.
Miners only mine when the expected reward is worth more than the cost of producing it. In practice, that means they mine when the value of the cryptocurrency exceeds the cost of the electricity (and other operating expenses) required to obtain it.
That naturally leads to an interesting idea.
If more mining power joins the network, the currency is likely overvalued relative to its production cost. The circulating supply should increase, pushing the price back down.
If mining power leaves the network, the currency has become too cheap to produce. The circulating supply should decrease, allowing scarcity to push the price back up.
The difficult part is making that happen without anyone being in charge.
My First Attempt
My first idea was to automatically lock and unlock individual coins based on the hashes of their identifiers.
Since cryptographic hashes are uniformly distributed, the protocol could decide which coins were spendable simply by comparing each identifier hash against a moving threshold tied to the mining difficulty.
As mining power increased, the difficulty would fall, making more coins spendable. When mining power decreased, the difficulty would rise again, automatically locking more coins and reducing the circulating supply.
On paper, it was elegant.
In practice, it was terrible.
Coins with unusually large identifier hashes would become intrinsically more valuable because they would remain spendable more often than others. Rational users would naturally start preferring those coins, and from there the entire system develops increasingly complicated incentive problems.
I spent a long time trying to fix those issues.
Every solution only introduced even worse ones.
Eventually I accepted that the entire approach was fundamentally flawed.
A Different Direction
Instead of forcing the protocol to decide which coins may circulate, I asked a different question:
What if users voluntarily adjusted the circulating supply themselves because doing so maximized their own profits?
That led me to combine two existing ideas.
Bitcoin uses Proof-of-Work. The more computational power and electricity you invest, the more frequently you statistically win block rewards.
Ethereum (conceptually speaking) associates rewards with locked capital. The more value you commit to the network, the greater your economic participation.
My proposal combines these ideas—but in a different way than traditional hybrid systems.
Consensus remains pure Proof-of-Work.
The probability of mining the next block depends only on hash power, exactly as in Bitcoin.
However, the size of the mining reward depends on how many coins the miner has voluntarily locked as stake.
In other words, Proof-of-Stake never determines who wins a block.
It only determines how much the winner earns.
The Feedback Loop
Once those two incentives coexist, the supply adjustment becomes entirely voluntary.
When electricity is cheap, miners are incentivized to unlock their coins and spend them on mining. More coins enter circulation, increasing supply and putting downward pressure on the price.
When electricity becomes expensive, miners are less willing to spend money competing for additional hash power. Instead, they lock more coins to increase the rewards they receive whenever they successfully mine a block.
That removes coins from circulation, reducing supply and increasing the currency's value.
No coins are confiscated.
No balances are frozen by the protocol.
Nobody is forced to participate in either strategy.
Every participant simply chooses whichever option maximizes their expected return, and the aggregate result becomes a decentralized monetary policy driven entirely by economic incentives.
That's the part I find most satisfying.
The protocol never wakes up one morning and says, "Congratulations. One percent of your balance is now locked."
Instead, every change in the money supply is the consequence of voluntary decisions made by rational participants pursuing their own interests.
To me, that's a much cleaner solution.
