1) What (just happened)? The Black Swan Crash, Explained. | Web3 Daily



TL;DR

$4T left the global markets as investors closed their Yen carry trades, leading to a crash in stocks, commodities, and crypto — but this could be the catalyst for hard rate cuts and liquidity injections, leading to a blow off top for crypto markets in 2024.

Full Story

If you opened your trading apps yesterday morning only to be accosted by a sea of red and want to know what happened — we’ve got you.

It all started with the Japanese ‘carry trade’…here’s what that is:

When a central bank raises its interest rates, its underlying currency typically goes up in value.

(E.g. The US dollar has been gaining strength over the past 18 months as the Federal Reserve continued to raise/hold interest rates).

…on the cooler side of the pillow — if a central bank keeps its rates low, its currency stays cheap.

(E.g. Exactly what the Bank of Japan has been doing, leading to a weaker/cheaper Yen).

And herein lies the opportunity for a ‘carry trade.’

Investors take out loans in Yen (with lower interest rates / repayments) to buy other assets that are gaining value, quicker (e.g. the US dollar, stocks, commodities, etc).

It works beautifully!

…until it doesn’t.

See, the Bank of Japan (BoJ) recently raised rates from 0.1% to 0.25% (making the Yen more valuable in the process), while the US Federal Reserve is expected to start lowering rates (which will make the US dollar less valuable).

Which means those carry trades are about to become less profitable, and require higher interest repayments.

So traders are selling out and taking their profits…only problem is:

There is (or at least, was) about $4 TRILLION dollars locked up in these carry trades.

So $4T of sell pressure just hit global stock, crypto, and commodity markets…

Add that to the pre-existing uncertainty surrounding potential war in the Middle East and the results in the upcoming US federal election…

And you get yesterday’s market crash.

From Sunday till the time of this writing, Bitcoin went from a high of $61k to a low of $49.5k, Ethereum went from a high of $2.9k to a low of $2.1k, and Solana went from a high of $145 to a low of $110.

Say it with us now: “Oooft!”

“…so, we’re all doomed?” — the market rn.

Let’s take a moment to remove our fingers from the panic button, and zoom out a bit.

Decode Dynamic Solidity Structs with Hyperledger Web3j

Decode Dynamic Solidity Structs with Hyperledger Web3j


In Solidity, dynamic structs are complex data types that can store multiple elements of varying sizes, such as arrays, mappings, or other structs. The system encodes these dynamic structs into binary format using Ethereum’s ABI (Application Binary Interface) encoding rules. The system encodes the structs whenever it stores or passes them in transactions.

Decoding this binary data is crucial for interpreting the state or output of a smart contract. This process involves understanding how Solidity organizes and packs data, particularly in dynamic types, to accurately reconstruct the original struct from its binary representation. This understanding is key to developing robust and interoperable decentralized applications.

Decoding dynamic structs in an external development environment that interacts with a blockchain network is challenging. These structs can include arrays, mappings, and nested structs of different sizes. They require careful handling to keep data accurate during encoding and decoding. In Hyperledger Web3j, we addressed this by creating object classes that match the expected struct format in the blockchain environment.

These object classes are designed to inherit from the org.web3j.abi.datatypes.DynamicStruct class, which is part of the ABI module. The developers designed this class to handle the complexities of encoding and decoding dynamic structs and other Solidity data types. The ABI module leverages Hyperledger Web3j’s type-safe mapping to ensure easy and secure interactions with these complex data structures.

However, when the goal is to extract a specific value from encoded data, creating a dedicated object can add unnecessary complexity. This approach can also use up extra resources. To address this, our contributors, calmacfadden and Antlion12, made significant improvements by extending the org.web3j.abi.TypeReference class.

Their enhancements allow dynamic decoding directly within the class, removing the need to create extra objects. This change simplifies the process of retrieving specific values from encoded data. This advancement reduces overhead and simplifies interactions with blockchain data.

Decoding dynamic struct before enhancement

To clarify, here’s a code example that shows how you could decode dynamic structs using Hyperledger Web3j before the enhancements.

/**
* create the java object representing the solidity dinamyc struct
* struct User{
* uint256 user_id;
* string name;
* }
*/
public static class User extends DynamicStruct {
public BigInteger userId;

public String name;

public Boz(BigInteger userId, String name) {
super(
new org.web3j.abi.datatypes.generated.Uint256(data),
new org.web3j.abi.datatypes.Utf8String(name));
this.userId = userId;
this.name = name;
}

public Boz(Uint256 userId, Utf8String name) {
super(userId, name);
this.userId = userId.getValue();
this.name = name.getValue();
}
}
/**
* create the function which should be able to handle the class above
* as a solidity struct equivalent
*/
public static final org.web3j.abi.datatypes.Function getUserFunction = new org.web3j.abi.datatypes.Function(
FUNC_SETUSER,
Collections.emptyList(),
Arrays.<typereference<?>>asList(new TypeReference() {}));

</typereference<?>

Now as the prerequisite is done, the only thing left is to call do the decode and here is an example:

@Test
public void testDecodeDynamicStruct2() {
String rawInput =
“0x0000000000000000000000000000000000000000000000000000000000000020”
+ “000000000000000000000000000000000000000000000000000000000000000a”
+ “0000000000000000000000000000000000000000000000000000000000000040”
+ “0000000000000000000000000000000000000000000000000000000000000004”
+ “4a686f6e00000000000000000000000000000000000000000000000000000000
“;

assertEquals(
FunctionReturnDecoder.decode(
rawInput,
getUserFunction.getOutputParameters()),
Collections.singletonList(new User(BigInteger.TEN, “John”)));
}

In the above test, we decoded and asserted that the rawInput is a User struct having the name John and userId 10.

Decoding dynamic struct with new enhancement

With the new approach, declaring an equivalent struct object class is no longer necessary. When the method receives the encoded data, it can immediately decode it by creating a matching reference type. This simplifies the workflow and reduces the need for additional class definitions. See the following example for how this can be implemented:

public void testDecodeDynamicStruct2() {
String rawInput =
“0x0000000000000000000000000000000000000000000000000000000000000020”
+ “000000000000000000000000000000000000000000000000000000000000000a”
+ “0000000000000000000000000000000000000000000000000000000000000040”
+ “0000000000000000000000000000000000000000000000000000000000000004”
+ “4a686f6e00000000000000000000000000000000000000000000000000000000
“;

TypeReference dynamicStruct =
new TypeReference(
false,
Arrays.asList(
TypeReference.makeTypeReference(“uint256”),
TypeReference.makeTypeReference(“string”))) {};

List decodedData =
FunctionReturnDecoder.decode(rawInput,
Utils.convert(Arrays.asList(dynamicStruct)));

List decodedDynamicStruct =
((DynamicStruct) decodedData.get(0)).getValue();

assertEquals(decodedDynamicStruct.get(0).getValue(), BigInteger.TEN);
assertEquals(decodedDynamicStruct.get(1).getValue(), “John”);}

In conclusion, Hyperledger Web3j has made great progress in simplifying the decoding of dynamic Solidity structs. This addresses one of the most challenging parts of blockchain development. By introducing object classes like org.web3j.abi.datatypes.DynamicStruct and enhancing the org.web3j.abi.TypeReference class, the framework now provides a more efficient and streamlined method for handling these complex data types.

Developers no longer need to create dedicated struct classes for every interaction, reducing complexity and resource consumption. These advancements not only boost the efficiency of blockchain applications but also make the development process easier and less prone to errors. This ultimately leads to more reliable and interoperable decentralized systems.
