What is Blockspace - An important economic model in the crypto market

The rise of distributed ledger technology not only creates new types of digital assets but also gives birth to a fundamental economic resource unit, considered by experts to be the most important product of the decade: Blockspace. Blockspace is more than just digital data storage; it represents a special type of computing resource where software commitments are immutably executed. In the era of the on-chain economy, blockspace plays the role of "digital real estate" powering the entire ecosystem from DeFi, social networks to blockchain games.

The nature and technical structure of Blockspace

To understand why blockspace has become an important economic model, it is necessary to analyze the technical nature in depth. Blockspace is the space available within each block of a blockchain, used to run source code and store state data. The crucial difference lies in the fact that in blockchain architecture, software plays the role of controlling hardware, instead of hardware controlling software like traditional centralized systems.

The superiority of the software model controlling hardware

In the traditional computing model, users and developers are always dependent on the hardware owner. A major tech company can change its access rules at any time. In contrast, blockchain operates based on the consensus mechanism of an independent network. This creates the concept of "can't be evil", where the rules are cryptographically enforced and cannot be unilaterally manipulated.

At Tan Phat Digital, we see this strong commitment turning blockchain into a scarce and highly valuable resource. Economists consider this a specific type of good that is sold on a per-action basis. Every time a transaction is made, the user is essentially buying a small portion of computing and storage resources to ensure the order is executed accurately and permanently.

Comparison between Blockspace and Block Size

The concept of blockspace is often confused with block size. Here are the basic differences between the two largest ecosystems:

• About units of measurement: Bitcoin uses Bytes/Megabytes to measure physical capacity, while Ethereum uses Gas to quantify computing power.

• About the limit mechanism: Bitcoin maintains a fixed level (e.g. 1MB for the original block) to ensure decentralization, while Ethereum applies the operates through the Gas Limit of each block.

• About design philosophy: Bitcoin is optimized for simple value storage. In contrast, Ethereum focuses on the ability to execute complex smart contracts.

• About scalability: Bitcoin scales through SegWit and Layer 2 like Lightning Network. Ethereum aims for Rollups and Sharding solutions to increase throughput.

Transaction fee market and operating mechanism

Blockspace operates as a pure market economy. As demand for the network increases, blockspace becomes more expensive, leading to an increase in transaction fees.

Supply and Demand Dynamics

Blockspace producers are miners or validators. They provide hardware and power to maintain network security and are rewarded with block rewards and transaction fees. This relationship is a complex B2B2C supply chain: blockchain attracts developers, and developers attract users to consume blockchain.

Transaction fees act as a filtering and prioritization mechanism. Users are willing to pay higher fees for priority processing. Ethereum's fee mechanism is now more stable thanks to upgrading EIP-1559 with the formula:

Total Fee = Gas Units x (Base Fee + Tip)

In which, the base fee will be burned, creating deflationary pressure, while tips are paid to validators. According to analysis by Tan Phat Digital, this mechanism directly links the value of the network with actual consumption demand.

Importance in the Blockchain economy

Blockspace is the most accurate measure of economic value. Total transaction fees reflect users' willingness to pay and the network effects of that ecosystem.

• Ethereum: Dominant with an estimated annual fee revenue of 2.73 billion USD, focusing on deep liquidity and maximum security.

• Solana: Reaching approximately 2.48 billion USD (including fees and MEV), prioritizing high-frequency trading with extremely low fees.

• Layer 2 (Base, Arbitrum):Is growing strongly, handling huge transaction volumes with lower profit margins but wider user coverage.

Layer 2 development and Dencun upgrade

The most difficult problem of Layer 1 is scalability. Layer 2 solutions appear to redefine the way blockchain is consumed through the Rollups mechanism, packaging thousands of transactions into a single batch to share costs on Layer 1.

The Dencun upgrade (March 2024) is an important turning point when introducing "Blobs". Blobs allow Layer 2s to temporarily post data to the network instead of storing it permanently, reducing data posting costs by 10 to 100 times. This ushers in the era of sub-1 cent transaction fees for end users.

MEV: The Underground Economy of Transaction Ordering

Maximal Extractable Value (MEV) is the profit gained from reordering transactions within a block. This is a competitive secondary market between members:

• Searchers: Look for profit opportunities from price differences.

• Builders: Aggregate transactions to create the most valuable block.

• Validators: Choose the block with the highest fee to propose to the network.

Although controversial Controversially, MEV is still an important source of revenue for network security, contributing about 10% of total transaction fees on Ethereum.

The shift to the Blockspace-as-a-Service model

The market is witnessing the emergence of specialized Data Availability (DA) layers, helping to break the storage monopoly:

• Ethereum Blobs: Maximum security, high synchronization, low cost estimated at 3.83 USD/MB.

• Celestia: Pioneering DAS technology, extremely low cost of only about 0.07 USD/MB (55 times cheaper).

• Avail: Focuses on fast confirmation (40 seconds) and multi-chain compatibility.

This competition is driving a future where blockspace becomes abundant, helping Web3 applications achieve a smooth Web2-like experience.

Security budget challenge

While cheap blockspace is beneficial for users, it poses a challenge for networks like Bitcoin. As block rewards decrease after each halving, Bitcoin needs a vibrant fee market to keep miners motivated. Tan Phat Digital commented that new protocols such as Ordinals are contributing to creating new demand for Bitcoin's blockspace, helping to strengthen the security budget in the long term.

Blockspace has affirmed its position as a platform economic model. The race to optimize blockchain is the race to expand and popularize blockchain technology to billions of users. Grasping the rules of this "digital real estate" will help investors and developers accurately position themselves in the future of the digital economy.
