Bitcoin developer Jimmy Song has revealed that the creators of the Taproot upgrade did not anticipate the "social attack surface" it would enable, leading to a surge in non-financial transactions like Ordinals and BRC-20 tokens. Song argues that Taproot has failed to deliver on its promised privacy and security enhancements, instead complicating functionalities like multisig.

Taproot's Unforeseen Consequences
Jimmy Song, a Bitcoin Core developer, stated in an X video that the Taproot upgrade, activated in November 2021, introduced an unintended "social attack surface." This allowed for the proliferation of Ordinals, BRC-20 tokens, and other non-financial transactions, which Song characterizes as "spam" on the network. He believes the developers did not account for this potential outcome.
Disappointment in Taproot's Performance
Song expressed disappointment with Taproot's performance, asserting that it did not fulfill the privacy and security expectations that Bitcoiners had placed in it. He specifically pointed to Schnorr signatures and Script Path Spend features, which were promoted as a more efficient alternative to multisig. However, Song contends that these features, in practice, became more complex than traditional multisig, leading to a poor user experience and making them a "non-starter."
Growing Divide Within the Bitcoin Community
Song's remarks highlight a growing schism within the Bitcoin community regarding the validation of different types of transactions. Proponents like Adam Back, Dennis Porter, and Luke Dashjr advocate for Bitcoin to remain focused on its core function as a peer-to-peer electronic cash system. Conversely, figures such as "Leonidas," a leader in the Ordinals community, embrace the Taproot upgrade, utilizing it for applications like Ordinals and Runes, and argue against transaction censorship.
The Ordinals and Runes Phenomenon
The emergence of Ordinals and Runes has intensified this debate. In June, over 30 Bitcoin Core developers agreed to remove the 80-byte limit on the OP_RETURN function, enabling more data storage on-chain. This move, however, has fueled concerns among some that Bitcoin Core might reverse such updates, leading to a migration towards Bitcoin Knots as an alternative node operator. The number of Bitcoin Knots nodes has seen a significant increase, now representing nearly 28% of the network.
Future Potential and Security Contributions
Despite his criticisms, Song has not entirely dismissed Taproot's potential, suggesting it could still prove beneficial through future developments like Ark decentralizing mining or BitVM increasing Bitcoin demand. Meanwhile, Leonidas argues that Ordinals and Runes have bolstered Bitcoin's security by contributing over $500 million in transaction fees, a crucial factor as the network's mining block subsidy continues to halve. However, the reliance on these fees remains volatile, with daily inscription fees fluctuating significantly.
