  • Ethereum: Query paginated API endpoint from end to the very first item by providing start and endtime parameters

    Consult Ethereum historical data with the final point of API paginado

    I can see that you are experiencing problems to recover data from the Binance API, which is a popular platform for trade and data storage. Specifically, you are looking to consult the historical data of Ethereum using a paginated end point.

    The problem that is found may be due to the way in which the Binance API manages the pagination or limitations of its API documentation. Here is an article that provides guidance on how to achieve this:

    Introduction

    Ethereum: Query paginated API endpoint from end to the very first item by providing start and endtime parameters

    Historical data are essential to analyze and make informed decisions about cryptocurrencies such as Ethereum. The Binance API offers an end point paginated to recover historical data, which allows you to obtain all the data available for each period.

    Step 1: Identify the consultation pattern of the end element to first place (E2I)

    To consult the E2I pattern, we need to understand how the Binance API handles the pagination. The general approach is to use the `to 'parameters to specify the starting and completion of the data.

    For example, suppose you want to recover all the historical operations of Ethereum from January 1, 2020 to January 31, 2022. You can use a consultation like this:

    JavaScript

    {

    "Method": "get",

    "URL": "

    "Parameters": {

    "Ids": []

    "Campos": [

    "open",

    "high",

    "low",

    "near",

    "volume"

    ]

    }

    }

    Step 2: Analyze and process the answer

    Once you receive the answer, analyze it to extract the relevant data. The end pointKLINESReturns a matrix of objects with several fields for each operation.

    For example:

    JSON

    [

    {

    "ID": 0,

    "Time brand": 1643723400,

    "Open": 10000000,

    "High": 15000000,

    "Bass": 9000000,

    "Close": 10500000,

    "Volume": 5000

    },

    {

    "ID": 1,

    "Time brand": 1643723405,

    "Open": 10200000,

    "High": 12000000,

    "Bass": 9200000,

    "Close": 10800000,

    "Volume": 6000

    },

    ...

    ]

    Step 3: Implement the pagination

    To implement the pagination, you must add the 'Limit parameter to your consultation. The value of the ‘limit’ depends on the number of elements returned per page.

    For example:

    `JavaScript

    {

    "Method": "get",

    "URL": "

    "Parameters": {

    "Ids": []

    "Campos": [

    "open",

    "high",

    "low",

    "near",

    "volume"

    ]

    }

    }

    `

    Conclusion

    The recovery of all the historical data of Ethereum available requires some work, but with the correct approach, you can achieve your goal. Following these steps and understanding how to implement the pagination using the Binance API, the E2I pattern should be able to consult successfully.

    If you still find problems or need more help, do not hesitate to ask. I will do everything possible to provide more orientation or point it out in the right direction.

  • Ethereum: Etherscan claimed MANA, DEXE & REQ tokens creation tx’s return different contractAddresses, they got an issue or I miss something?

    Ethereum Ethercan error: Creating many TXS tokens returns different contract addresses

    The Ethercan platform has recently experienced a problem with the return of creation transactions for several tokens, including humans. This error led to confusion for both users and programmers. In this article we will arrive what the problem causes and we will provide a solution.

    Problem:

    API Ethercan returns various addresses of contracts for the same token, which can be misleading when working with many contracts. The problem is how API TOKEN Creation transactions supports.

    case studies -OKEN mana:

    Let’s take Mana as an example. According to his website at Ethercan ( the Creation -Transaction is:

    `Sol

    0xf1e6db9d9b7e8ff4bfedddddddddddddddd77ce55cafa93be94

    However, if you try to access this address of the contract with Ethercan (https: //etherscan.io/address/…), there is an error message back:

    `Text

    Contract Address Error: 0x0000000000000000000000000000000000000000000000

    `

    This indicates that the creation transaction has not been successfully implemented.

    Solution:

    To solve this problem, Ethercan provides a bypass so that users can provide the address of the contract in the “Contractddress” area of ​​the API request. In this way, the API can return the right address for the token, even if many contracts have created a token at the same time.

    Here is an updated example:

    Api Ethercan Request:

    `Json

    {

    "Method": "ETH_Sendtransaction",

    "Parameter": [

    {

    "Data": "0x0f5D2FB29FB7D3CFEE44A200298F468908C942"

    }

    ],],

    "Contract": "0x0f5d2FB29FB7D3CFEE44A200298F468908cc942" // right this address on the right right

    }

    What next:

    1

    • Check whether many contracts have not created token at the same time, as this can also lead to problems with Apiethercan.

    If you follow these steps, you should be able to solve the problem and effectively restore the transaction of creating the Mana token in Ethercan.

    Tips and variants:

    • Check the address of the contract in the contract code or in the implementation information to check whether it is correct.

    • If the problem remains, you should check the transactions or Ethereum diaries to ensure that there are no problems when creating a tokens.

    • In some cases, it may be necessary to use a different API endpoint or an inquiry format to download the creation transaction.

    I hope that this will help to explain all confusion caused by the return of Ethercan from various contractual attacks for the same token. If you have any further questions or doubts, you can ask yourself!

    Ethereum What Does Like

  • Ethereum: What is the difference between chainstate and blocks folder?

    Ethereum: Understanding Chainstate Vs. Blocks the folder

    In the ecosystem of the Ethereum, and the chain paths I Bloksfolderare key components for the Blockchain data and transition. However, they serve for various purposes, which is crucial to understanding their differences before you dive into reading and displaying data on the web interface.

    Chainstate

    MapChainstateis the central warehouse of the Ethereum state, which includes various information like:

    • Block height

    • Block number

    • Block the time tag

    • Number of transactions

    • Gas ​​price

    • Unconfirmed number of transactions

    TheChainstate ‘map stores this information in the hierarchical structure, with each file represents a block or blockchain section. The files are organized in directory such as “State_root”, State_tree" andtx_count.

    Block the folder

    Blocksfolderis a response to individual blockchain failure blocks. Each block contains different data such as:

    • Block hash

    • Previous block hash (parent hash)

    • Number of transactions

    • Unconfirmed number of transactions

    • Gas ​​price

    • Time mark

    Blocksfolderstores each block in a separate file, with each file represents one block.

    Key differences

    While both folders store the same types of data, there are key differences:

    • Chainstateis the Central State of the Ethereum State, and Wereas Blocksfolder ‘stores individual blocks.

    • Files in Chainstate have a hierarchical structure, with each directory containing sub -taxes and files, whileBlocksfolder has separate files for each block.

    Reading and Data View

    To read and display data on web -fronteda such as Blockchain Explorer website, you will also need to access the Chainstate and Blocks Blocks” folder. Here you can do it using Solidity (Ethereum programming) and Web3.JS:

    `Javascript

    Import * as a web3 from “Web3”;

    Const Web3 = New Web3 (new web3provers.httpprovider (‘

    // Get a chain

    Const chain = web3.esth.chainstate;

    // Get all blocks

    Async Function Getblocks () {{

    Const Txlist = wait for web3.Eth.get leaf transaction ();

    for (some i = 0; i

    Const block = txlist [i] .block;

    // Read the block of data from Chainstate

    Console.log (block.timestamp);

    Iche

    Iche

    // Get a certain block by his hash

    Async Function Getblockbyhash () {{

    Const blockhash = ‘0x1234567890ABCDEF’;

    Const blockdata = waiting for web3.Eth.getblock (blockhash, true);

    // Read the Blocks Block from Blocksfolder

    Console.log (blockdata.hash);

    Iche

    `

    Data display on web front

    To display data on web -fronteda such as Blockchain Explorer website, you will need to use the web3Js Library "Ethers" to interact with the Ethereum network and retrieve certain data. You can then use HTML5 canvas or other technologies for data visualization technology.

    Here's an example of how you can display a block time mark using HTML5 Canvas:

    Calling JSON-RPC APIs with C:A Guide

    JSON-RPC (JavaScript Object Notation Remote Procedure Call) is a lightweight, open standard for remote procedure call that allows developers to interact with servers over HTTP. While the JSON-RPC protocol has become increasingly popular in recent years, it’s still possible to call these APIs from languages ​​other than JavaScript, including C.

    In this article, we’ll walk through how to make RPC calls from C, focusing on calling a JSON-RPC API using the curl command-line tool and its equivalent for Windows: cURL.

    Why use C for RPC calls?

    While it’s possible to call JSON-RPC APIs in other languages, such as Python or Ruby, C provides several advantages:

    • Performance

      : C is a low-level language that allows direct access to hardware resources, resulting in faster execution times.

    • Memory Management

      : C has manual memory management, which can be more efficient than garbage collection mechanisms found in other languages.

    • Portability: C code can run on any platform that supports the standard library and cURL/curl, making it a great choice for cross-platform development.

    Step 1: Set up your JSON-RPC API

    First, you’ll need to set up your JSON-RPC API. This typically involves creating a server-side application using languages ​​like Node.js, Python, or Ruby that expose an interface with specific methods and parameters.

    For this example, we’ll use the curl command-line tool to interact with our JSON-RPC API.

    Step 2: Write C code for the API

    Here’s an example of how you could write a simple JSON-RPC API using C:

    “`c

    #include

    #include

    // Define the API structure

    typedef struct {

    char* method;

    void (func)(void);

    } rpc_api;

    // Function to handle incoming RPC requests

    rpc_api handle_rpc_request(rpc_api api, const char* method) {

    // Check if the request is valid

    if (strcmp(method, “example_method”) != 0) {

    printf(“Invalid request: %s\n”, method);

    return NULL;

    }

    // Call the function with a placeholder argument value

    char* arg = “Hello World!”;

    api->func(arg);

    return api;

    }

    // Function to handle incoming RPC responses

    void handle_rpc_response(void response, int status_code) {

    switch(status_code) {

    case 200:

    // Return the response as a JSON string

    fprintf(stderr, “Response: %s\n”, response);

    break;

    default:

    fprintf(stderr, “Error: %d\n”, status_code);

    return NULL;

    }

    }

    // Main function to handle incoming RPC requests

    int main() {

    rpc_api api;

    // Initialize the API with a placeholder function

    api.method = “example_method”;

    api.func = handle_rpc_request;

    // Set up an HTTP server listener

    int server_fd, new_socket;

    struct sockaddr_in address;

    socklen_t addrlen = sizeof(address);

    // Bind port 8080 to the socket

    if ((server_fd = socket(AF_INET, SOCK_STREAM, 0)) == 0) {

    perror(“socket”);

    exit(1);

    }

    address.sin_family = AF_INET;

    address.sin_port = htons(8080);

    inet_pton(AF_INET, “127.0.0.1”, &address.sin_addr);

    // Listen for incoming connections

    if (bind(server_fd, (struct sockaddr *)&address, sizeof(address)) == -1) {

    perror(“bind”);

    exit(1);

    }

    // Accept incoming connections

    if ((new_socket = accept(server_fd, (struct sockaddr *)&address, &addrlen)) < 0) {

    perror(“accept”);

    exit(1);
