Don’t Forfeit your Harvest

“The farmer sows the word. The ones by the road are the ones where the word is sown; and when they have heard, immediately Satan comes, and takes away the word which has been sown in them. These in the same way are those who are sown on the rocky places, who, when they have heard the word, immediately receive it with joy. They have no root in themselves, but are short-lived. When oppression or persecution arises because of the word, immediately they stumble. Others are those who are sown among the thorns. These are those who have heard the word, and the cares of this age, and the deceitfulness of riches, and the lusts of other things entering in choke the word, and it becomes unfruitful. Those which were sown on the good ground are those who hear the word, and accept it, and bear fruit, some thirty times, some sixty times, and some one hundred times.”” (Mark‬ ‭4:14-20‬ ‭WEB‬‬)

No matter what tactics the enemy uses, his goal is the same: to prevent God’s word from producing a good harvest in your life.

When he snatches it away quickly, it could be as simple as when you are not paying attention during a sermon because of using your smartphone to scroll through social media. As a result, you did not even hear most of what the preacher was saying.

If that does not work, Satan can choose the forceful method or the soft method. He either comes like a roaring lion or a fowler.

The lion method would be to intimidate you into giving up on God’s promises. For example, you might have started trusting God for a breakthrough in your finances, but the enemy deliberately sends many unforeseen bills your way. Appliances at home start breaking down, and freak injuries or illnesses happen, leading to expensive medical bills. These are some ways Satan roars so that you lose trust in God for provision.

On the other hand, the fowler method would be to set traps to lure you into worldly things. He wants you obsessed and distracted with the lust of the eyes, the lust of the flesh, and the pride of life. This way, you will lose focus on God’s word and the seed that stops being watered in your heart will not produce a harvest.

For example, he may get you obsessed with politics, entertainment, earning money, lewdness, so that your mind is never on God’s word. If you keep leaving a plant unattended and in dry weather, it will wither away.

Only Christians who patiently persevere through all these dirty tactics of the enemy will experience a good harvest from having faith in God’s word.

Obviously the enemy knows the power of God’s word and that is why he tries his best to stop you from having faith in it.

The devil knows that once God’s word produces harvests in your life, he will have to relinquish any hold he had in that area. Try as he might, he is defenseless against God’s power.

Hearing God’s word, believing it, and speaking it over yourself may seem like such over-preached truths, but that is because God’s way for us is just that simple. Jesus completed all the hard work at the cross, and now we get to restfully reap the benefits of what He did for us.

It is easy to say, “I know this already,” but the question is: are you really doing it consistently? Ask yourself this and if this message stirs up your faith to get back on the right track of voraciously hearing and hearing God’s word, then its purpose is done!

0. Intro

The announcement of Uniswap v3 is no doubt one of the most exciting news in the DeFi place recently 🔥🔥🔥

While most have talked about the impact v3 can potentially bring on the market, seldom explain the delicate implementation techniques to realize all those amazing features, such as concentrated liquidity, limit-order-like range orders, etc.

Since I’ve covered Uniswap v1 & v2 (if you happen to know Mandarin, here are v1 & v2), there’s no reason for me to not cover v3 as well ✅

Thus, this article aims to guide readers through Uniswap v3, based on their official whitepaper and examples made on the announcement page. However, one needs not to be an engineer, as not many codes are involved, nor a math major, as the math involved is definitely taught in your high school, to fully understand the following content 😊😊😊

If you really make it through but still don’t get shxt, feedbacks are welcomed! 🙏

There should be another article focusing on the codebase, so stay tuned and let’s get started with some background noise!

1. Uniswap & AMM recap

Before diving in, we have to first recap the uniqueness of Uniswap and compare it to traditional order book exchanges.

Uniswap v1 & v2 are a kind of AMMs (automated market marker) that follow the constant product equation x * y = k, with x & y stand for the amount of two tokens X and Y in a pool and k as a constant.

Comparing to order book exchanges, AMMs, such as the previous versions of Uniswap, offer quite a distinct user experience:

AMMs have pricing functions that offer the price for the two tokens, which make their users always price takers, while users of order book exchanges can be both makers or takers.

Uniswap as well as most AMMs have infinite liquidity¹, while order book exchanges don’t. The liquidity of Uniswap v1 & v2 is provided throughout the price range [0,∞]².

Uniswap as well as most AMMs have price slippage³ and it’s due to the pricing function, while there isn’t always price slippage on order book exchanges as long as an order is fulfilled within one tick.

In an order book, each price (whether in green or red) is a tick. Image source: https://ftx.com/trade/BTC-PERP

¹ though the price gets worse over time; AMM of constant sum such as mStable does not have infinite liquidity

² the range is in fact [-∞,∞], while a price in most cases won’t be negative

³ AMM of constant sum does not have price slippage

2. Tick

The whole innovation of Uniswap v3 starts from ticks.

For those unfamiliar with what is a tick:

Source: https://www.investopedia.com/terms/t/tick.asp

By slicing the price range [0,∞] into numerous granular ticks, trading on v3 is highly similar to trading on order book exchanges, with only three differences:

The price range of each tick is predefined by the system instead of being proposed by users.

Trades that happen within a tick still follows the pricing function of the AMM, while the equation has to be updated once the price crosses the tick.

Orders can be executed with any price within the price range, instead of being fulfilled at the same one price on order book exchanges.

With the tick design, Uniswap v3 possesses most of the merits of both AMM and an order book exchange! 💯💯💯

So, how is the price range of a tick decided?

This question is actually somewhat related to the tick explanation above: the minimum tick size for stocks trading above 1$ is one cent.

The underlying meaning of a tick size traditionally being one cent is that one cent (1% of 1$) is the basis point of price changes between ticks, ex: 1.02 — 1.01 = 0.1.

Uniswap v3 employs a similar idea: compared to the previous/next price, the price change should always be 0.01% = 1 basis point.

However, notice the difference is that in the traditional basis point, the price change is defined with subtraction, while here in Uniswap it’s division.

This is how price ranges of ticks are decided⁴:

Image source: https://uniswap.org/whitepaper-v3.pdf

With the above equation, the tick/price range can be recorded in the index form [i, i+1], instead of some crazy numbers such as 1.0001¹⁰⁰ = 1.0100496621.

As each price is the multiplication of 1.0001 of the previous price, the price change is always 1.0001 — 1 = 0.0001 = 0.01%.

For example, when i=1, p(1) = 1.0001; when i=2, p(2) = 1.00020001.

p(2) / p(1) = 1.00020001 / 1.0001 = 1.0001

See the connection between the traditional basis point 1 cent (=1% of 1$) and Uniswap v3’s basis point 0.01%?

Image source: https://tenor.com/view/coin-master-cool-gif-19748052

But sir, are prices really granular enough? There are many shitcoins with prices less than 0.000001$. Will such prices be covered as well?

Price range: max & min

To know if an extremely small price is covered or not, we have to figure out the max & min price range of v3 by looking into the spec: there is a int24 tick state variable in UniswapV3Pool.sol.

Image source: https://uniswap.org/whitepaper-v3.pdf

The reason for a signed integer int instead of an uint is that negative power represents prices less than 1 but greater than 0.

24 bits can cover the range between 1.0001 ^ (2²³ — 1) and 1.0001 ^ -(2)²³. Even Google cannot calculate such numbers, so allow me to offer smaller values to have a rough idea of the whole price range:

1.0001 ^ (2¹⁸) = 242,214,459,604.341

1.0001 ^ -(2¹⁷) = 0.000002031888943

I think it’s safe to say that with a int24 the range can cover > 99.99% of the prices of all assets in the universe 👌

⁴ For implementation concern, however, a square root is added to both sides of the equation.

How about finding out which tick does a price belong to?

Tick index from price

The answer to this question is rather easy, as we know that p(i) = 1.0001^i, simply takes a log with base 1.0001 on both sides of the equation⁴:

Image source: https://www.codecogs.com/latex/eqneditor.php

Let’s try this out, say we wanna find out the tick index of 1000000.

Image source: https://ncalculators.com/number-conversion/log-logarithm-calculator.htm

Now, 1.0001¹³⁸¹⁶² = 999,998.678087146. Voila!

⁵ This formula is also slightly modified to fit the real implementation usage.

3. Concentrated liquidity

Now that we know how ticks and price ranges are decided, let’s talk about how orders are executed in a tick, what is concentrated liquidity and how it enables v3 to compete with stablecoin-specialized DEXs (decentralized exchange), such as Curve, by improving the capital efficiency.

Concentrated liquidity means LPs (liquidity providers) can provide liquidity to any price range/tick at their wish, which causes the liquidity to be imbalanced in ticks.

As each tick has a different liquidity depth, the corresponding pricing function x * y = k also won’t be the same!

Each tick has its own liquidity depth. Image source: https://uniswap.org/blog/uniswap-v3/

Mmm… examples are always helpful for abstract descriptions 😂

Say the original pricing function is 100(x) * 1000(y) = 100000(k), with the price of X token 1000 / 100 = 10 and we’re now in the price range [9.08, 11.08].

If the liquidity of the price range [11.08, 13.08] is the same as [9.08, 11.08], we don’t have to modify the pricing function if the price goes from 10 to 11.08, which is the boundary between two ticks.

The price of X is 1052.63 / 95 = 11.08 when the equation is 1052.63 * 95 = 100000.

However, if the liquidity of the price range [11.08, 13.08] is two times that of the current range [9.08, 11.08], balances of x and y should be doubled, which makes the equation become 2105.26 * 220 = 400000, which is (1052.63 * 2) * (110 * 2) = (100000 * 2 * 2).

We can observe the following two points from the above example:

Trades always follow the pricing function x * y = k, while once the price crosses the current price range/tick, the liquidity/equation has to be updated.

√(x * y) = √k = L is how we represent the liquidity, as I say the liquidity of x * y = 400000 is two times the liquidity of x * y = 100000, as √(400000 / 100000) = 2.

What’s more, compared to liquidity on v1 & v2 is always spread across [0,∞], liquidity on v3 can be concentrated within certain price ranges and thus results in higher capital efficiency from traders’ swapping fees!

Let’s say if I provide liquidity in the range [1200, 2800], the capital efficiency will then be 4.24x higher than v2 with the range [0,∞] 😮😮😮 There’s a capital efficiency comparison calculator, make sure to try it out!

Image source: https://uniswap.org/blog/uniswap-v3/

It’s worth noticing that the concept of concentrated liquidity was proposed and already implemented by Kyper, prior to Uniswap, which is called Automated Price Reserve in their case.⁵

⁶ Thanks to Yenwen Feng for the information.

4. Range orders: reversible limit orders

As explained in the above section, LPs of v3 can provide liquidity to any price range/tick at their wish. Depending on the current price and the targeted price range, there are three scenarios:

current price < the targeted price range

current price > the targeted price range

current price belongs to the targeted price range

The first two scenarios are called range orders. They have unique characteristics and are essentially fee-earning reversible limit orders, which will be explained later.

The last case is the exact same liquidity providing mechanism as the previous versions: LPs provide liquidity in both tokens of the same value (= amount * price).

There’s also an identical product to the case: grid trading, a very powerful investment tool for a time of consolidation. Dunno what’s grid trading? Check out Binance’s explanation on this, as this topic won’t be covered!

In fact, LPs of Uniswap v1 & v2 are grid trading with a range of [0,∞] and the entry price as the baseline.

Range orders

To understand range orders, we’d have to first revisit how price is discovered on Uniswap with the equation x * y = k, for x & y stand for the amount of two tokens X and Y and k as a constant.

The price of X compared to Y is y / x, which means how many Y one can get for 1 unit of X, and vice versa the price of Y compared to X is x / y.

For the price of X to go up, y has to increase and x decrease.

With this pricing mechanism in mind, it’s example time!

Say an LP plans to place liquidity in the price range [15.625, 17.313], higher than the current price of X 10, when 100(x) * 1000(y) = 100000(k).

The price of X is 1250 / 80 = 15.625 when the equation is 80 * 1250 = 100000.

The price of X is 1315.789 / 76 = 17.313 when the equation is 76 * 1315.789 = 100000.

If now the price of X reaches 15.625, the only way for the price of X to go even higher is to further increase y and decrease x, which means exchanging a certain amount of X for Y.

Thus, to provide liquidity in the range [15.625, 17.313], an LP needs only to prepare 80 — 76 = 4 of X. If the price exceeds 17.313, all 4 X of the LP is swapped into 1315.789 — 1250 = 65.798 Y, and then the LP has nothing more to do with the pool, as his/her liquidity is drained.

What if the price stays in the range? It’s exactly what LPs would love to see, as they can earn swapping fees for all transactions in the range! Also, the balance of X will swing between [76, 80] and the balance of Y between [1250, 1315.789].

This might not be obvious, but the example above shows an interesting insight: if the liquidity of one token is provided, only when the token becomes more valuable will it be exchanged for the less valuable one.

…wut? 🤔

Remember that if 4 X is provided within [15.625, 17.313], only when the price of X goes up from 15.625 to 17.313 is 4 X gradually swapped into Y, the less valuable one!

What if the price of X drops back immediately after reaching 17.313? As X becomes less valuable, others are going to exchange Y for X.

The below image illustrates the scenario of DAI/USDC pair with a price range of [1.001, 1.002] well: the pool is always composed entirely of one token on both sides of the tick, while in the middle 1.001499⁶ is of both tokens.

Image source: https://uniswap.org/blog/uniswap-v3/

Similarly, to provide liquidity in a price range < current price, an LP has to prepare a certain amount of Y for others to exchange Y for X within the range.

To wrap up such an interesting feature, we know that:

Only one token is required for range orders.

Only when the current price is within the range of the range order can LP earn trading fees. This is the main reason why most people believe LPs of v3 have to monitor the price more actively to maximize their income, which also means that LPs of v3 have become arbitrageurs 🤯

I will be discussing more the impacts of v3 in 5. Impacts of v3.

⁷ 1.001499988 = √(1.0001 * 1.0002) is the geometric mean of 1.0001 and 1.0002. The implication is that the geometric mean of two prices is the average execution price within the range of the two prices.

Reversible limit orders

As the example in the last section demonstrates, if there is 4 X in range [15.625, 17.313], the 4 X will be completely converted into 65.798 Y when the price goes over 17.313.

We all know that a price can stay in a wide range such as [10, 11] for quite some time, while it’s unlikely so in a narrow range such as [15.625, 15.626].

Thus, if an LP provides liquidity in [15.625, 15.626], we can expect that once the price of X goes over 15.625 and immediately also 15.626, and does not drop back, all X are then forever converted into Y.

The concept of having a targeted price and the order will be executed after the price is crossed is exactly the concept of limit orders! The only difference is that if the range of a range order is not narrow enough, it’s highly possible that the conversion of tokens will be reverted once the price falls back to the range.

As price ranges follow the equation p(i) = 1.0001 ^ i, the range can be quite narrow and a range order can thus effectively serve as a limit order:

When i = 27490, 1.0001²⁷⁴⁹⁰ = 15.6248.⁸

When i = 27491, 1.0001²⁷⁴⁹¹ = 15.6264.⁸

A range of 0.0016 is not THAT narrow but can certainly satisfy most limit order use cases!

⁸ As mentioned previously in note #4, there is a square root in the equation of the price and index, thus the numbers here are for explantion only.

5. Impacts of v3

Higher capital efficiency, LPs become arbitrageurs… as v3 has made tons of radical changes, I’d like to summarize my personal takes of the impacts of v3:

Higher capital efficiency makes one of the most frequently considered indices in DeFi: TVL, total value locked, becomes less meaningful, as 1$ on Uniswap v3 might have the same effect as 100$ or even 2000$ on v2.

The ease of spot exchanging between spot exchanges used to be a huge advantage of spot markets over derivative markets. As LPs will take up the role of arbitrageurs and arbitraging is more likely to happen on v3 itself other than between DEXs, this gap is narrowed … to what extent? No idea though.

LP strategies and the aggregation of NFT of Uniswap v3 liquidity token are becoming the blue ocean for new DeFi startups: see Visor and Lixir. In fact, this might be the turning point for both DeFi and NFT: the two main reasons of blockchain going mainstream now come to the alignment of interest: solving the $$ problem 😏😏😏

In the right venue, which means a place where transaction fees are low enough, such as Optimism, we might see Algo trading firms coming in to share the market of designing LP strategies on Uniswap v3, as I believe Algo trading is way stronger than on-chain strategies or DAO voting to add liquidity that sort of thing.

After reading this article by Parsec.finance: The Dex to Rule Them All, I cannot help but wonder: maybe there is going to be centralized crypto exchanges adopting v3’s approach. The reason is that since orders of LPs in the same tick are executed pro-rata, the endless front-running speeding-competition issue in the Algo trading world, to some degree, is… solved? 🤔

Anyway, personal opinions can be biased and seriously wrong 🙈 I’m merely throwing out a sprat to catch a whale. Having a different voice? Leave your comment down below!

6. Conclusion

That was kinda tough, isn’t it? Glad you make it through here 🥂🥂🥂

There are actually many more details and also a huge section of Oracle yet to be covered. However, since this article is more about features and targeting normal DeFi users, I’ll leave those to the next one; hope there is one 😅

If you have any doubt or find any mistake, please feel free to reach out to me and I’d try to reply AFAP!

Stay tuned and in the meantime let’s wait and see how Uniswap v3 is again pioneering the innovation of DeFi 🌟

Live by the “Present Truth”

“Therefore I will not be negligent to remind you of these things, though you know them, and are established in the present truth...For we did not follow cunningly devised fables, when we made known to you the power and coming of our Lord Jesus Christ, but we were eyewitnesses of his majesty. For he received from God the Father honor and glory, when the voice came to him from the Majestic Glory, “This is my beloved Son, in whom I am well pleased.” We heard this voice come out of heaven when we were with him on the holy mountain.” (2 Peter‬ ‭1:12, 16-18‬ ‭WEB‬‬)

The apostle Peter wrote to the church, saying that they were “established in the present truth”.

The existence of a present truth necessitates that there was a former truth.

I believe that he was referring to the change in covenants, from the Old Covenant of the Law (former truth) to the New Covenant of Grace (present truth).

He was probably addressing those who disbelieved that the Law has been replaced by Grace, and who wanted to continue keeping the Ten Commandments.

The New Covenant of Grace is all about God’s Son, our Lord Jesus Christ.

Peter then recounted an incident that happened to him many years ago, when he saw Jesus transfigured on the mountain.

“After six days, Jesus took with him Peter, James, and John his brother, and brought them up into a high mountain by themselves. He was transfigured before them. His face shone like the sun, and his garments became as white as the light. Behold, Moses and Elijah appeared to them talking with him. Peter answered, and said to Jesus, “Lord, it is good for us to be here. If you want, let’s make three tents here: one for you, one for Moses, and one for Elijah.” While he was still speaking, behold, a bright cloud overshadowed them. Behold, a voice came out of the cloud, saying, “This is my beloved Son, in whom I am well pleased. Listen to him.” When the disciples heard it, they fell on their faces, and were very afraid. Jesus came and touched them and said, “Get up, and don’t be afraid.” Lifting up their eyes, they saw no one, except Jesus alone. As they were coming down from the mountain, Jesus commanded them, saying, “Don’t tell anyone what you saw, until the Son of Man has risen from the dead.”” (Matthew‬ ‭17:1-9‬ ‭WEB‬‬)

The transfiguration was firmly etched in Peter’s mind. He saw Jesus’ majesty—the glory He had before His incarnation.

But right after seeing that, he was starstruck when he saw Moses and Elijah who appeared and spoke with Jesus.

Moses is the mediator of the Old Covenant of the Law, while Elijah is one of the most highly esteemed Old Testament prophets.

He stumbled over these two great men of God, and put Jesus on the same level as them by asking if he should pitch three tents for them to stay in.

God the Father was displeased by this, and He overshadowed Jesus, Moses and Elijah with a bright cloud, and told Peter, James, and John to listen to Jesus only.

Moses and Elijah disappeared, and the apostles only saw Jesus alone.

This is the way God the Father intended—for His Son to receive all the glory, honor, and majesty.

Under the New Covenant of Grace, the “present truth” is that we listen to Jesus alone.

It is not about keeping the Ten Commandments or observing the ominous warnings of the prophets anymore. Don’t be deceived by “cunningly devised fables” invented by the minds of men who seek to use the Law to enforce behavior modification on ignorant believers.

The entire Bible is about Jesus and the revelation of His story.

“Beginning from Moses and from all the prophets, he explained to them in all the Scriptures the things concerning himself.” (Luke‬ ‭24:27‬ ‭WEB‬‬)

Notice how Jesus expounded the Scriptures to Cleopas and the other disciples on the road to Emmaus, by explaining to them the things concerning Himself. Moses refers to the first five books of the Old Testament which were written by Moses, and the prophets are represented by Elijah.

Both Moses and Elijah are pointing to Jesus Christ who would be born as a Man to redeem mankind from their sins by dying on the cross, and eventually, Jesus will return to reign on David’s throne as the eternal King of Israel!

Did you ever wonder why Jesus only brought Peter, James and John to the mountain? I believe they were chosen because of their names.

Peter means “stone”, representing the Law which was engraved on stone tablets. James means “to supplant” (to be replaced). John means “grace of God”.

Putting their names together, we derive this meaning: the Law has been replaced by Grace.

The Law is the former truth, while Grace is the present truth which we are to be established in. We need to be constantly reminded of this truth so that we can keep our eyes on Jesus. Like Abba God said from the bright cloud, “Listen to Him.”

“For the law was given through Moses. Grace and truth were realized through Jesus Christ.” (John‬ ‭1:17‬ ‭WEB‬‬)

No matter what challenges you are facing today, choose to keep your eyes on Jesus, and let His Spirit lead you. Jesus is the full realization of grace and truth. He is God’s righteousness. We must stop mixing the covenants and live by Grace alone!

THE SCIENCE OF DEDUCTION

"You appear to be astonished," he said, smiling at my expression of surprise. "Now that I do know it I shall do my best to forget it."

"To forget it!"

"You see," he explained, "I consider that a man's brain originally is like a little empty attic, and you have to stock it with such furniture as you choose. A fool takes in all the lumber of every sort that he comes across, so that the knowledge which might be useful to him gets crowded out, or at best is jumbled up with a lot of other things, so that he has a difficulty in laying his hands upon it. Now the skilful workman is very careful indeed as to what he takes into his brain attic. He will have nothing but the tools which may help him in doing his work, but of these he has a large assortment, and all in the most perfect order. It is a mistake to think that that little room has elastic walls and can distend to any extent. Depend upon it there comes a time when for every addition of knowledge you forget something that you knew before. It is of the highest importance, therefore, not to have useless facts elbowing out the useful ones."

"But the Solar System!" I protested.

"What the deuce is it to me?" he interrupted impatiently; "you say that we go round the sun. If we went round the moon it would not make a pennyworth of difference to me or to my work."

I was on the point of asking him what that work might be, but something in his manner showed me that the question would be an unwelcome one. I pondered over our short conversation, however, and endeavoured to draw my deductions from it. He said that he would acquire no knowledge which did not bear upon his object. Therefore all the knowledge which he possessed was such as would be useful to him; I enumerated in my own mind all the various points upon which he had shown me that he was exceptionally well-informed. I even took a pencil and jotted them down. I could not help smiling at the document when I had completed it. It ran in this way:—
