I haven't seen such a bold design for a while, AMPL impressed Blue Fox Note! Regardless of the success of AMPL, it will leave a mark on the history of encryption. At the same time, it will definitely be a highly controversial project, which will accompany it until it finally succeeds or fails.
For this reason, Blue Fox Note will continue to pay attention to its subsequent evolution.
Bitcoin's vision and challenges
The birth of Bitcoin was to build a system completely different from fiat currencies. It tried to change the problems of currency inflation and the recurring economic crises of the credit economic system. This is also Satoshi Nakamoto's original vision: to build a peer-to-peer electronic cash payment system.
In the practice of Bitcoin for more than ten years, it has achieved great success, from when few people were interested in it, it has grown into a cryptocurrency with a market value of more than 160 billion U.S. dollars. In the course of this development, people gradually discovered that Bitcoin presents the characteristics of digital gold. Due to its future rising expectations, Bitcoin holders are more willing to hoard rather than use it for daily consumption and payment.
Bitcoin has gradually occupied the position of digital gold. Its main purpose is not a medium of exchange or a unit of valuation, but a store of value. (Of course, as long as it occupies the top spot in the store of value, it also means that it still has huge space. At present, the value of gold is about 10 trillion US dollars. Compared with the store of value in the form of gold, Bitcoin has its own advantages. Bitcoin. The currency still has a lot of room from its end.)
Bitcoin's current direction is largely determined by its inherent characteristics:
Hard top
There are only 21 million Bitcoins, and it will not be issued. This causes it to become scarce. The scarcity has led to huge expectations of rising prices. But at the same time, this has also led people to regard it as digital gold for storage.
Throughput and speed limitations
Bitcoin's TPS is about 7, which makes it completely unable to become a currency for daily payments. For remittances, this waiting time is acceptable, but if it is a daily payment, it cannot be tolerated.
These inherent characteristics of Bitcoin have their greatness, because it tries to solve the problems of inflation and credit economic system, but from the development of the past ten years, Bitcoin still has a long way to go.
As Bitcoin gradually moves toward digital gold, people gradually expand their perspectives to a larger area. Is it possible to design a stable encrypted native currency that can simultaneously realize the functions of value storage, unit of valuation, and medium of exchange.
There are currently three main schools of stablecoin experiments. One is stablecoins anchored to USD, such as USDC, which can be redeemed 1:1 with the US dollar; the other is stablecoins generated based on over-collateralization of encrypted assets, such as DAI, which anchors the target. For the US dollar, but not hard anchored. The last type is a fully encrypted native decentralized stable currency. Regarding the exploration of stablecoins, Blue Fox Notes has previously published articles such as "The Holy Grail of Stablecoins: Exploration of New Paths", "Meter's Road to Stablecoins: Explorations That Are Completely Different from Libra".
AMPL is one of the boldest explorations of cryptocurrency experiments
AMPL is a continuation of cryptocurrency innovation. It combines some of the characteristics of Bitcoin and legal currency. If an equilibrium can be developed, it is possible to develop new things in the next ten years. Of course, this is also accompanied by huge risks and uncertainties.
At the same time, AMPL cannot currently be regarded as a stable currency. It is not supported by fiat currency or other assets. It is more like a native cryptocurrency, trying to find a certain equilibrium of crypto assets, trying to develop asset types that are not highly related to Bitcoin and other crypto assets.
In the short term, it is unlikely to become a price-stable cryptocurrency. Of course, if it has a chance to achieve a balance of supply and demand in the future, it may form a certain effect of encrypted native stable currency. But this is unlikely to be achieved in a long time. Therefore, in the short term, AMPL is also an encrypted token with certain volatility, rather than a crypto-native stable currency.
AMPL is trying to become an asset that is not highly relevant to other cryptocurrencies in the short term. The medium-term goal is to become one of the basic components of DeFi, such as a decentralized encrypted collateral. The ultimate goal is to become a better Bitcoin that can be used at the same time. It has the characteristics of value storage, pricing unit and medium of exchange, and has the characteristics of encryption native, no inflation, flexible supply, no trust, no dilution, etc.
In short, AMPL's mechanism design and vision destined it to be a highly controversial project. People's perception of it will be polarized.
AMPL applies the logic of supply and demand to elastic supply
As mentioned above, AMPL does not have a fixed supply. The problem is that since there is no fixed supply. So, what is the basis for the increase or decrease of its supply?
The most basic logic of economics is based on the relationship between supply and demand. This is the basis of all transactions and the essence of the market. AMPL applies the logic of supply and demand to cryptocurrency, and regards currency as a commodity based on supply and demand.
Traditional monetary policy is generally an important tool to regulate the economy. The formulation and implementation of its policies involve political, economic and social factors, and often face information asymmetry. This is why Hayek believes that the traditional monetary system cannot operate effectively.
AMPL is relatively simple and rude, and the main logic that determines its supply is the relationship between supply and demand in the market. It will not associate monetary policy with economic or social issues (such as corporate credit crisis, employment and many other complex issues).
Because its logic is relatively simple and transparent, its circulation and price fluctuations are clearly visible and expected, which makes it possible to reach a certain balance through the market game mechanism.
How is it done?
AMPL is a smart contract based on Ethereum. The AMPL protocol can automatically adjust the amount of AMPL tokens on all user wallets. When the market price of AMPL is higher than a certain threshold of the target price, the balance of tokens in the wallet will also automatically increase, which is equivalent to issuing additional issuance to all wallets in proportion; when the market price of AMPL is lower than a certain threshold of the target price, the tokens in the wallet The balance will be reduced proportionally.
This is the most important "token base readjustment" in the AMPL protocol. The token base is re-adjusted every 24 hours (currently at 10 am Beijing time). This adjustment will not cause dilution, but will increase or decrease in the same proportion.
Since the adjustment is related to the price of AMPL, this requires the participation of the oracle. The AMPL protocol uses a market oracle system, including whitelisted independent data providers, who provide 24-hour average prices based on transaction volume weights to chain aggregators.
According to the price of AMPL, if the agreement finds that the total amount of AMPL needs to be readjusted, it will adjust it once a day. However, in the implementation process, it has a smoothing process of supply. This is also part of the AMPL protocol algorithm, whose purpose is to avoid overreaction of the protocol.
Specifically, if the exchange rate is 1.2AMPL:1, according to the AMPL mechanism, each wallet balance should be increased by 20% of AMPL tokens. If the exchange rate is 0.8AMPL:1, then each wallet balance should be reduced by 20%. However, this adjustment will not be executed immediately, and it will be over-smoothed for some time.
This period of time is in days, so this period of time can be counted as k days. If it is a deviation of the above 20%, the agreement will update the wallet balance according to 20%/k. If k is 10 days, then the updated balance is 2% of the total. However, the percentage of this numerator is recalculated every day and is executed every 24 hours. This operation is stateless, that is, every day the agreement will recalculate the supply target according to its latest price, and then calculate the target for the next k days accordingly. To adjust the supply.
In summary, AMPL has a target price. If its target price is $1, then its nominal exchange rate is higher than a certain threshold, and the agreement will increase the number of tokens for all users year-on-year; if the AMPL price is lower than the target price by a certain amount Threshold, then the agreement will reduce the number of tokens held by the user.
