How To Get The Right Inscription ID For Ordinals: A Guide

Hey everyone! 👋 Let's dive into something super important when you're working with Ordinals: getting the correct inscription ID. If you're into Ordinals, you know that these IDs are crucial. They're like the unique fingerprints that identify each inscription. But here's the kicker – the way things are currently set up can lead to some wonky situations, especially when it comes to how different platforms (like explorers) handle these IDs. I'm talking about case-sensitivity and those pesky leading zeros. This guide is here to help you understand the issues and find a solution, ensuring you always get the right ID.

The Problem: Inconsistency in Inscription IDs

So, what's the deal? Well, the main problem lies in how inscription IDs are generated and interpreted. The format for an inscription ID typically looks like this: <64-hex>i<decimal index>. For example, a1f06831ae932db82de3b0007e4da21971bfe4a1i0. This format is used to identify inscriptions on the blockchain. The first part is the transaction ID (txid), a 64-character hexadecimal string, and the second part is the index, a number representing the order of the inscription within the transaction. The issue arises because some explorers might not treat these IDs the same way.

One of the main culprits is case-insensitivity. This means that some explorers might treat uppercase and lowercase letters in the txid the same. So, a1f06831ae932db82de3b0007e4da21971bfe4a1i0 could be treated the same as A1f06831ae932db82de3b0007e4da21971bfe4a1i0. While this might seem like a minor detail, it can lead to inconsistencies. Furthermore, leading zeros can also cause problems. For example, 000000a1f06831ae932db82de3b0007e4da21971bfe4a1i0 might be treated the same as a1f06831ae932db82de3b0007e4da21971bfe4a1i0 by some explorers. This can cause different platforms to display different IDs for the same inscription.

These inconsistencies might seem small, but they can create significant issues, especially when the inscription ID is used as a seed for generating pseudorandom outputs for generative collections. Imagine you are building a generative art project, and each artwork's features are determined by the inscription ID. If different viewers or platforms interpret the ID differently, the resulting artwork will be inconsistent across platforms. This destroys the very purpose of Ordinals which aims for a single source of truth across the network.

The Solution: Canonicalization

The solution? Canonicalization. Simply put, it means making sure that the inscription ID is always represented in a consistent, standardized format. To achieve this, you can use a normalization function. This function takes an inscription ID as input and transforms it into a standard format. The goal is to make sure that regardless of how the input ID is formatted initially, the output will always be the same. This process ensures that the inscription ID is always consistent, regardless of how it is initially presented.

Here's an example of how a canonicalization function might work, as suggested in the original request:

function normalizeInscriptionId(input) {
  const m = String(input).trim().match(/^([0-9a-fA-F]{64})[iI]([0-9]+)$/);
  if (!m) throw new Error("Invalid format: expected <64-hex><i><decimal index>");

  const txid = m[1].toLowerCase();
  const index = BigInt(m[2]).toString();
  return `${txid}i${index}`;
}

Let's break down what this function does:

• Input: It takes an inscription ID as input, which is expected to be a string.
• Validation: It first checks if the input matches the expected format <64-hex>i<decimal index>. If the input doesn't match this format, it throws an error.
• Lowercase Conversion: The function converts the txid part of the inscription ID to lowercase. This ensures that the hex characters are always in the same case (lowercase), which removes any case-sensitivity issues.
• Index Conversion: The index part of the ID is converted to a string. This can help standardize the number format and prevent any potential issues with different numeric representations.
• Output: Finally, the function returns the normalized inscription ID in the format txidiindex. The returned value is the canonicalized inscription ID.

By using this function, you can ensure that your inscription IDs are always in a consistent and standardized format. This eliminates the problems caused by case-sensitivity and other formatting variations. This consistency is essential for ensuring that your Ordinals are correctly identified and displayed across all platforms.

Why Canonicalization Matters

Why is this so important? Because consistency is key in the world of Ordinals and NFTs in general. Here's a breakdown of why you should care about getting the canonical inscription ID:

• Ensuring Compatibility: When dealing with different platforms, explorers, and wallets, you need to ensure that they all recognize the same inscription ID. Canonicalization makes this happen.
• Preventing Confusion: Imagine trying to track a collection of Ordinals, and the IDs keep changing based on where you look. Canonicalization avoids this confusion.
• Maintaining Integrity: If the ID is used as a seed for any on-chain or off-chain processes, like generating traits for a generative art project, a consistent ID ensures that results are predictable and replicable.
• Boosting Trust: When the community knows that an inscription ID is unambiguous, it builds trust in the system.

By implementing a normalization function, you're creating a single source of truth for your inscription IDs. This enhances the reliability of your applications and projects. It makes sure that everyone sees the same ID, no matter where they're looking.

Implementing the Normalization Function

Implementing the normalization function is pretty straightforward. You can add it to your codebase wherever you need to work with inscription IDs. For example, if you're building an application that displays Ordinals, you can use the function to normalize the IDs before displaying them. If you're building a tool that generates Ordinals, you can use the function to normalize the IDs before they are generated. Here’s how you might do it in a simple JavaScript environment:

function normalizeInscriptionId(input) {
  const m = String(input).trim().match(/^([0-9a-fA-F]{64})[iI]([0-9]+)$/);
  if (!m) throw new Error("Invalid format: expected <64-hex><i><decimal index>");

  const txid = m[1].toLowerCase();
  const index = BigInt(m[2]).toString();
  return `${txid}i${index}`;
}

// Example usage
const inscriptionId1 = "A1f06831ae932db82de3b0007e4da21971bfe4a1i0";
const inscriptionId2 = "a1f06831ae932db82de3b0007e4da21971bfe4a1i0";

const normalizedId1 = normalizeInscriptionId(inscriptionId1);
const normalizedId2 = normalizeInscriptionId(inscriptionId2);

console.log("Original ID 1:", inscriptionId1);
console.log("Original ID 2:", inscriptionId2);
console.log("Normalized ID 1:", normalizedId1);
console.log("Normalized ID 2:", normalizedId2);
//The output for both normalizedId1 and normalizedId2 will be the same: a1f06831ae932db82de3b0007e4da21971bfe4a1i0

This example shows how to normalize different formats of inscription IDs to a consistent format. Using the normalization function before working with IDs ensures consistent results, regardless of the input format. Implementing this function is a small step that will save you a lot of headaches later. By ensuring all your IDs are standardized, you improve your project's overall reliability and trustworthiness.

Conclusion: Stay Consistent!

Maintaining consistency in inscription IDs is crucial for the smooth operation of Ordinals projects. Implementing a canonicalization function is a simple but effective way to ensure that your IDs are always in a standardized format. This helps prevent inconsistencies across different platforms and maintains the integrity of your projects. I highly recommend implementing this method in your projects! Keep your IDs consistent, and your Ordinals projects will be much more reliable and enjoyable. Thanks for reading!
