Blockchain Transactions: Beyond Speed and Size

The intrigue around Blockchain technology has significantly grown, with cryptocurrencies featuring prominently in recent market trends. Over the past decade, a pertinent question regarding the number of transactions per second (TPS) a particular Blockchain can accommodate has become a point of discussion.

In many ways, the measurement of TPS has been understood as a benchmark of success, determining how quickly a Blockchain can process transactions. Even traditional systems like Visa allegedly handling 1,700 transactions per second provides a familiar comparison for a space often shrouded in complexity. However, as we delve deeper into this issue, we begin to question whether this fascination with TPS holds true merit? Is it a mere numbers game, or is there more to it that we have yet to consider?

The Counter-Narrative: Shifting Perspectives on TPS

A closer investigation into the world of Blockchain reveals that there might be a counter-narrative to the prevalent discourse surrounding TPS. As Chris DeRose, former Counterparty and Dogecoin developer stated, “A lot of this stuff about transactions per second was more vanity than anything.” His argument posits that emphasizing TPS does not capture the full potential and promise of Blockchain technology.

A significant factor to consider is the diversity of transactions that occur within the Blockchain. These are not necessarily uniform and their processing might extend beyond mere counts per second. Furthermore, the narrative neglects the delay in obtaining transaction confirmations on Blockchain. Hence, there is a need to re-evaluate the obsession with TPS, encouraging a deeper understanding of what truly underpins transaction efficiency in Blockchain.

Probing the Depths: Unpacking the Complexity of Blockchain TPS

To put things into perspective, while Bitcoin’s TPS may be disappointingly low, its strength lies in approximately 4.6 transactions per second with high-value transactions. On the other hand, systems like Ethereum process a significantly higher number of transitions per second. However, this volume does not necessarily translate into efficiency or security. The balance between scalability, security, and decentralization—commonly known as the ‘trilemma’ in Blockchain—is inevitably tied up with TPS.

Moreover, Blockchains with lower TPS aren’t necessarily less efficient or valuable. For instance, DeRose emphasized that “Bitcoin is very much ‘bigger’ than anything else out there” despite its low TPS. He argues that looking at the byte size of transactions could provide a better measure than a mere count of transactions.

Therefore, while TPS might provide a sense of measurable success, its relevance and influence on the effectiveness of a Blockchain can be transient and context-dependent.
