The Witness Discount: Why Some Bytes Are Cheaper Than Others


🧱 The Blockchain Fee Conundrum: Balancing Bitcoin’s Future with Inscription Economics 📈

Imagine living in a world where blockchain technology is much more than a mere tool; it is a consistent source of income. The world is already witnessing such a change, with cryptocurrencies and blockchain platforms controlling the realms of finance and technology, and offering innovative solutions to complex problems. So, the question here is, can these blockchain innovations serve as a persistent revenue source? Can an individual develop a blockchain-based business from scratch that generates substantial income every month? This blog post sheds light on these questions and offers an inspiring roadmap for aspiring blockchain entrepreneurs.

🤹 The Blockchain Balancing Act: Mining Profits and User Costs

Starting a blockchain-based business is no cakewalk. Entrepreneurs need to understand the intricacies of blockchain fees, as these fees are the lifeblood that keeps the ecosystem running smoothly. With blockchain, particularly Bitcoin, the limited space available in each block is akin to real estate in a prime location; everyone wants a piece of it. This demand for block space, especially with the recent uptick in Bitcoin inscriptions, has led to a significant rise in transaction fees for on-chain activities. Inscriptions, part of witness data in Bitcoin transactions—which enjoy a favorable rate of 1/4 the cost of other transaction data—are at the center of this conversation, with some asking: Why the special treatment?

🤔 Bytes on a Budget: The Economics Behind Cheaper Witness Data

What lies behind the cost structure of different types of data is Bitcoin’s clever incentive system. It aligns the interests of miners and transactors through fees, but historically, node runners have not benefited in the same way. The advent of important protocols like SegWit aimed to balance the costs of data between node runners and transactors. SegWit, by separating signatures from transaction data, effectively made certain bytes cheaper due to their less fundamental role in validation and the absence of an ongoing cost in the UTXO index.

🔍 The Quest for Scarcity: Blockchain’s Version of Demand and Supply

Creating balance within the blockchain ecosystem isn’t just about fee adjustments; it also involves managing the dynamics of supply and demand. Initially, the blockchain was uncapped, but that liberty could not last forever. To protect the network from overload and keep it sustainable for node runners, Bitcoin followed Satoshi Nakamoto’s lead and implemented a fixed block size limit. This served to put a cap on transactional freedom, ensuring a delicate balance that works to maintain a precious sense of crypto scarcity.

🔑 Locked-In Efficiency: The P2SH Revolution

The transformation doesn’t stop at block size limits. Another pivotal development was the shift created by Pay to Script Hash (P2SH), which nudged the fee burden from senders to recipients for complex scripts. P2SH’s introduction paved the way for a more egalitarian and efficient transaction paradigm, resolving a burden that could have otherwise led to a divide based on transaction complexity.

🤲 From Inputs to Outputs: Aligning Costs and Incentives

There’s also a nuanced financial dance between the different elements that make up a transaction—inputs and outputs. SegWit’s arrival brought a nuanced new cost analysis, taking into account each piece of data’s impact on the broader system within and beyond individual transactions. It revealed the hidden, ongoing costs of the outputs and how they interact with the UTXO index, vital for maintaining the blockchain’s integrity.

💡 The Taproot Twist: Innovative Bitcoin Locking with a Touch of Controversy

Taproot, while ‘just’ a new method of utilizing SegWit to lock Bitcoin, ruffled feathers by smoothing the path for inscriptions—these optional additions to transactions that have been stretching the fee market. The result? A discounted data domino effect that has been advantageous for inscribers but left others questioning if these discounts should continue, especially as they potentially distort market dynamics.

🌐 SegWit to Taproot: A Network Evolves

The SegWit soft fork, in pursuit of fixing TXID malleability and fostering future protocols like the Lightning Network, adjusted weights and limits on transactional data—with controversial results. The insulation of authorization data from the block limit gave rise to alternative and additional considerations for managing these segregated bytes, weighing the network’s collective needs against individual transaction demands.

🖋️ Inscriptions and Their Economic Impression on Bitcoin

Inscriptions, the heart of this discussion, take advantage of the weight system wherein their data demands are less taxing, charged at 1/4 vByte per byte. Efficient, less computationally intensive, but is it fair when considering the broader Bitcoin community? That’s the lingering question echoing through the blocks of the blockchain, as enthusiasts debate the balance between fostering innovative uses and maintaining equitable access to this finite digital space.


The world of blockchain and Bitcoin is perpetually balancing the scales of innovation and practicality. As we explore the complex dynamics of fees, data weights, and the push towards economic density within transactions, we see an ecosystem ripe with opportunities for the astute entrepreneur. The transformative power of blockchain technology lies not just within its technical prowess, but in its ability to harmonize the diverse incentives of its participants. With resilience, ingenuity, and a commitment to forward-thinking collaboration, the future of blockchain business is bright for those bold enough to engage with its unfolding tapestry.
