In a significant development, the founder of BRC-20, Domo, has announced a security enhancement proposal that introduces a novel core function called “fraction”. Domo, BRC-20’s creator, suggested a security improvement. This essential function optimizes crypto token transmission by implementing strict validity constraints, making it harder for attackers to interrupt the process.
BRC-20 Boosts Security with ‘Fraction’ Function
BRC-20, known for its simplicity, consciously uses the “fraction” function. The suggested modification will improve crypto token transmission for all users while maintaining protocol principles. Unintended inscription transfers can destabilize tokens and hamper users’ operations. The “fraction” function addresses this issue. The BRC-20 protocol allows users to generate transfer inscriptions to any address, allowing for some flexibility. This feature presents a feasible avenue for disruptions and attacks, but is rare.
The BRC-20 protocol’s “fraction” function imposes exact transfer validity requirements. This proactive strategy increases the complexity and cost of system damage to deter attackers.
The “fraction” function is essential to the BRC-20 protocol and hinders modular implementation. The idea defines the allowable transfer values and may require a minimum margin for a valid transfer designation.

This option is unneeded for the average user because it only affects the beginning step of the inscription transfer operation (inscribe-transfer) and does not affect legitimate inscription transmission. Padding allows users to efficiently remove surplus satoshis from the UTXO (Unspent Transaction Output) during transfer completion. Token deployers can use the minimum and maximum parameters to create claimdrops, Ethereum-style airdrops. This method improves security and spurs bridge and relay innovation.
BRC 20 Community Opens Discussion on Protocol Change
Several alternatives were considered while writing this proposal. Signature requirements for transfer inscriptions, specified UTXOs for producing them, and monitor spent satoshis from wallets that preserve balances were among these possibilities. However, these methods increased complexity, impacted user perception, and possibly created new exploitation opportunities.
Since this amendment is the first major change to the protocol since its establishment, the BRC-20 community wants to hear your thoughts on its pros and cons. Initial comment is due in two weeks, with an extension possible if a consensus is not reached. In the next step, meta-protocol concerns will be addressed. The approach seeks to balance security and usability with dynamic blockchain technology.
