Throughout 2023 and early 2024, Bitcoin ordinals have emerged as a hotly debated topic among Bitcoin enthusiasts. Proponents view them as a potential game-changer in data storage and a boon for Bitcoin network security.

However, skeptics criticize them as a deviation from Bitcoin’s primary purpose as a peer-to-peer currency. 

But what are Bitcoin ordinals?

This blog post dives into Bitcoin ordinals' brief history, the network upgrades that led to its creation, and the broader implications for the Bitcoin industry. 

Understanding Bitcoin Ordinals: Serial Numbers for Sats

The Concept of Bitcoin Ordinals

Bitcoin Ordinals are very similar to serial numbers. They act as a unique identifier for each unit of Bitcoin, known as a "satoshi or sat" (short for “Satoshi Nakamoto”).

Just as every U.S. paper dollar bill carries a serial number, each satoshi is assigned a serial number based on its mining order. 

The Emergence of Bitcoin Inscriptions

Bitcoin inscriptions are akin to digital captions attached to individual sats. These inscriptions can include: 

  • Text

  • Images

  • Audio

… even digital games. Their integration with ordinals leads to the creation of unique Bitcoin artifacts, which we will explore next.

Bitwise recently disclosed the wallet address for its Bitcoin ETF — a first among the top 11 issuers of spot Bitcoin ETFs.

Following this disclosure, the wallet has attracted a variety of contributions, including Bitcoin ordinals and unique satoshis and has amassed inscription donations valued at $6,083 and boasts a collection of more than 16,000 inscriptions.

The Mechanics of Bitcoin Ordinals and Digital Artifacts

Creating Digital Collectibles

Bitcoin ordinals and inscriptions are primarily used to create "artifacts" or digital collectibles akin to sports cards on the Bitcoin network. These artifacts, also known as Bitcoin NFTs, use ordinals as serial numbers and inscriptions for attaching an image. 

They have found applications in data storage, domain names, and, most notably, the BRC-20 protocol. The BRC-20 standard opens up new possibilities for the Bitcoin network, allowing it to use decentralized finance (DeFi) protocols and various blockchain-based applications.

  • 24-hour trading volume: $ 753.86M

  • Market Cap: $842.00M

  • Market Dominance: 0.04%. 

Bitcoin NFTs vs. Traditional NFTs

BRC-20 artifacts differ from traditional NFTs in several ways. Unlike Ethereum NFTs, which rely on smart contracts and centralized servers, they are stored directly on the Bitcoin blockchain. 

The Bitcoin blockchain has undergone two essential modifications — SegWit and Taproot — which have since facilitated the emergence of ordinals.

SegWit Upgrade 

In 2017, the Bitcoin community implemented SegWit or segregated witness data to increase network capacity and improve scalability. 

Before SegWit, the OP_RETURN function included the arbitrary data on the transaction block: 

  • Transaction time

  • The sender/receiver’s address 

SegWit modifies storing data, separates signature information from transaction data, optimizes block space, and reduces transaction fees.

This revision modified the structure of Bitcoin transactions and boosted the block size capacity from 1 MB to 4 MB.

Taproot Upgrade 

The Taproot upgrade, implemented on November 14th 2021, enhanced Bitcoin’s protocol by introducing Schnorr Signatures, MAST, and Tapscript, significantly improving privacy, scalability, and smart contract flexibility. 

Schnorr what? WTH is a MAST?

In simple terms, Taproot:  

  • Batches multiple signatures and transactions together, making verifying transactions on the network easier and faster.

  • Scrambles transactions with single and multiple signatures together. It made it more difficult to identify transaction inputs on Bitcoin’s blockchain.

The Taproot Assets Protocol is for issuing assets on the Bitcoin blockchain.

Taproot Assets leverages newly created assets and their transfers in an efficient and scalable manner. Multiple assets can be created and transferred in a single Bitcoin UTXO, while witness data is transacted and stored off-chain.

What are Runes?

Runes is a fungible token protocol for the Bitcoin network that aims to be simple and UTXO-based. Rune balances are held by UTXOs, and transactions are identified using specific script conditions.

Runes officially released on Bitcoin mainnet at block 840,000 — April 20th, 2024.

Runes Protocol Overview

  • Purpose: Allows users to create and manage fungible tokens directly on the Bitcoin blockchain.

  • Developer: Casey Rodarmor.

  • Advantages: Provides a streamlined alternative to existing token standards.

Key Features

  • Infrastructure Utilization: Leverages Bitcoin’s Unspent Transaction Output (UTXO) model.

  • Efficiency: Creates fungible tokens with minimal impact on blockchain size, unlike some BRC20 tokens that can cause congestion.

Benefits of Runes

  • Token Creation: Empowers users to craft various fungible tokens, such as:

    • Loyalty points

    • Community currencies

    • Fractional ownership of real-world assets

  • Security: Utilizes the inherent security of the Bitcoin network.

  • Versatility: Expands Bitcoin’s reach and utility beyond its core function as a digital currency.

Summary

  • Runes Protocol: Empowers users to create diverse tokens on the Bitcoin blockchain.

  • Impact: Enhances Bitcoin’s versatility while maintaining its security and efficiency.

Key Differences Between Runes and Ordinals

Runes and Ordinals have sparked a fascinating debate within the Bitcoin community. While both aim to expand Bitcoin’s utility beyond its core function, they approach it in fundamentally different ways. Here’s a breakdown of their key differences:

Fungibility vs. Non-Fungibility

  • Runes:

    • Designed for fungibility.

    • Each Rune of the same type is identical and interchangeable.

    • Ideal for applications like loyalty points or stablecoins.

  • Ordinals:

    • Non-fungible by nature.

    • Each Ordinal represents a unique unit on the Bitcoin blockchain, similar to a one-of-a-kind NFT.

Data Storage Approach

  • Runes:

    • Uses existing Unspent UTXOs.

    • Attaches data to UTXOs, transforming them into representations of various digital assets.

    • Maintains compatibility with existing Bitcoin infrastructure.

  • Ordinals

    • Embeds data directly within the “witness” section of a Bitcoin transaction.

    • Inscribes data onto individual Satoshis, creating unique NFTs embedded within the blockchain.

Transfer Mechanism

  • Runes:

    • Offers a simple and user-friendly transfer mechanism.

    • Can be transferred like any other Bitcoin transaction, without complex UTXO splitting.

  • Ordinals:

    • Transferring involves a more complex process.

    • Splits a UTXO containing the Ordinal data into several new UTXOs.

    • These “split” UTXOs containing the Ordinal information travel across the network.

Scalability and Transaction Fees

  • Runes:

    • Leverages Bitcoin’s existing UTXO model.

    • Minimizes data added to the blockchain.

    • Potentially leads to lower transaction fees compared to Ordinals.

  • Ordinals:

    • Directly inscribe data onto individual Satoshis.

    • Potentially, this leads to larger transaction sizes and higher fees.

    • Could impact the scalability of the Bitcoin network in the long run.

Security and Risk Factors

  • Runes:

    • Inherently secure by leveraging Bitcoin’s established security infrastructure.

  • Ordinals:

    • Introduce potential risk factors.

    • Permanent inscription of data onto the blockchain.

    • Vulnerabilities in the Ordinal protocol could expose inscribed data to security risks.

Use Case

  • Runes:

    • Ideal for representing fungible digital assets.

    • Applications include loyalty points, in-game currencies, or stablecoins within the Bitcoin ecosystem.

  • Ordinals:

    • Suitable for creating unique, non-fungible digital collectibles, artwork, or other digital assets.

    • Enables verifiable on-chain ownership.

Integration with Existing Infrastructure

  • Runes:

    • Seamlessly integrates with existing Bitcoin wallets and exchanges.

    • Relies on the UTXO model.

  • Ordinals:

    • May require dedicated wallets and infrastructure for managing and interacting with Ordinal NFTs.

Debating the Merits and Drawbacks of Bitcoin Ordinals

Critics' Perspective

Critics argue that ordinals and artifacts detract from Bitcoin’s original purpose as a decentralized financial system. They raise concerns about network congestion, increased transaction fees, and slower processing times, potentially undermining Bitcoin’s role as an economic system.

Advocates' Stance

Supporters tout the unparalleled security of the Bitcoin blockchain for data storage, attracting new users with diverse interests beyond money. They highlight the potential economic benefits for miners, thereby bolstering network security.

Final Thoughts

Bitcoin ordinals represent a fascinating evolution in the Bitcoin ecosystem, offering potential benefits and challenges. Ordinals are not just a technological curiosity but a development that could redefine the scope of digital assets within the Bitcoin framework.

While they promise to expand Bitcoin’s utility, they also come with a set of challenges that must be thoughtfully considered.
