Bitcoin Ordinals set to cease existing: developer addresses vulnerability

The Bitcoin community is abuzz as the ORDI token, based on the Bitcoin Ordinals protocol, skyrockets, becoming the first BRC-20 token to breach a $1 billion market cap after an 850% monthly gain.

However, underlying this success is a brewing controversy, with Bitcoin Core developer Luke Dashjr raising alarms about an exploitation vulnerability affecting the blockchain.

What are Bitcoin Ordinals?

Bitcoin Ordinals represent a pioneering concept in the cryptocurrency sphere, serving as the equivalent of non-fungible tokens (NFTs) on the Bitcoin blockchain. Every satoshi, the smallest Bitcoin unit, is assigned a serial number or ordinal based on its mining order. This ordinal is crucial for tracking satoshi ownership and history.

The Ordinals protocol allows for the inscription of additional content directly onto satoshis. This process, known as inscribing, enables the creation of unique digital assets, including NFTs, leveraging the security and decentralization of the Bitcoin blockchain. However, controversy surrounds Ordinals, with some viewing the activity akin to spam, leading to concerns over its impact on the Bitcoin network.

While Ordinals have gained popularity for NFT creation, their utilization extends beyond this realm. Ordinals' ability to embed data directly into the Bitcoin blockchain without relying on secondary protocols distinguishes them from other blockchain-based NFTs. The controversy surrounding their potential cessation raises questions about the future landscape of token creation and digital asset innovation within the Bitcoin ecosystem.

Bitcoin Ordinals exploitation sparks concerns

Luke Dashjr, a Bitcoin Core developer, highlighted on Twitter that "Inscriptions" are exploiting a vulnerability, enabling them to bypass data size limits set in Bitcoin Core since 2013. The bug, fixed in Bitcoin Knots v25.1, still leaves Bitcoin Core vulnerable in the upcoming v26 release, according to Dashjr.

Dashjr hopes that the bug will however get fixed before the v27 upgrade next year.

The news comes after an extraordinary rally that saw the ORDI token, which is based on Bitcoin Ordinals, become the first BRC-20 token to exceed a $1 billion market capitalization.

ORDI reached an all-time high of over $65, marking an 850% gain in a month. Despite a slight dip from this peak, the token's value remains over 2,000% higher than its September 11 all-time low of $2.86. The surge in ORDI's value coincides with increased inscription activity, contributing to Bitcoin network congestion and higher transaction fees.
