In October 2025, the Bitcoin Core v30.0 beta was released, quietly removing the 80-byte limit on the OP_RETURN (Bitcoin script opcode) data field, increasing the amount of data that can be embedded in a single transaction to 100KB (100,000 bytes). This seemingly simple parameter adjustment is, in fact, a historic recognition of the TBC technology roadmap by the Bitcoin ecosystem. From the expansion of OP_RETURN to the concept of large blocks, from the prototype of smart contracts to the on-chain data revolution, every step of the transformation in Bitcoin v30 confirms the foresight of TBC as the "vanguard of Bitcoin innovation."

1. Technological Convergence: Bitcoin v30's Implicit Replication of TBC's Core Design

At the outset of TBC's launch, it proposed the radical idea of "reconstructing the UTXO model to achieve large blocks + smart contracts", which at the time was seen as a rebellious attempt against the spirit of Bitcoin. However, as the Bitcoin main chain exposed functional deficiencies in Layer 2 scaling (such as the Lightning Network), the community gradually realized that merely relying on sidechains and middleware could not meet the demands of complex applications. TBC verified a completely different path through hard forks—releasing Bitcoin's original potential by reconstructing the underlying protocol while maintaining decentralization. The OP_RETURN expansion in Bitcoin v30 is a subtle replication of TBC's technological route: the former achieves data expansion through software optimization, while the latter breaks performance boundaries through hardware reconstruction, but both point to the same goal—liberating the potential of on-chain data. TBC's radical innovations have sparked controversy, but the market has voted with its feet to prove its value, allowing TBC to cover areas such as payments, NFTs, and DeFi. Its core advantage lies in the fact that the UTXO model is naturally suited for parallel processing, 4GB block capacity easily accommodates high-frequency trading, and the BVM architecture enables near-zero gas fees for smart contract execution. These characteristics not only fill the gaps in the Bitcoin ecosystem but also reveal the underlying laws of blockchain technology—performance and security are not mutually exclusive; the key lies in how to balance them. Although the expansion of Bitcoin v30 has not reached the block limit, the loosening of OP_RETURN has already laid the groundwork for enhanced Layer 1 functionality in the future. It can be anticipated that as the Bitcoin main chain gradually unlocks data storage capabilities, TBC's UTXO smart contract architecture will become the preferred reference for developers to migrate.

2. Route Convergence: TBC's Radical Exploration of Bitcoin's Technological Boundaries

From a technological evolution perspective, the adjustments of Bitcoin v30 resemble a rehearsal for a "self-revolution." Over the past five years, the Bitcoin core team has oscillated between "conservatism" and "innovation": the Taproot (mainnet) upgrade introduced smart contract logic, and Schnorr (Schnorr signature algorithm) optimized transaction efficiency, but these patch-ups have never been able to break through the shackles of Layer 2. The emergence of TBC acts as a mirror, reflecting the true needs of the Bitcoin ecosystem — developers yearn for a development experience comparable to Ethereum within a secure framework, and users require trustless on-chain services. The recent OP_RETURN expansion is less a compromise by Bitcoin towards TBC than a signal of its proactive embrace of change. In the future, as the functionality of Bitcoin Layer 1 gradually enhances (such as Schnorr signature expansion), its technological trajectory will increasingly converge with TBC: the former continues Satoshi Nakamoto's vision with "phased expansion," while the latter validates technological possibilities with "all-at-once reconstruction," ultimately both will converge under the consensus of "security first."

3. Future Outlook: TBC - The "Ideal State" of the Bitcoin Ecosystem and the Guiding Beacon

TBC reconstructs the UTXO model through a hard fork, proving that the Bitcoin ecosystem can achieve a leap in performance through radical innovation while maintaining security. Its "large blocks + UTXO smart contracts + cross-chain interconnectivity" trinity design provides a technical feasibility verification for the OP_RETURN expansion of Bitcoin v30. In the future, the Layer 1 upgrade of Bitcoin (such as Schnorr signature expansion) may resonate with TBC's UTXO smart contracts. The division of labor between the main chain and the forked chain will become clearer: the Bitcoin main chain continues to play the role of "digital gold + data anchor," meeting basic needs through a Layer 1/2 combination; TBC public chain will take on the banner of high-frequency trading, complex contracts, and cross-chain interoperability. The ultimate form of cross-chain interoperability may give rise to a "Bitcoin-based public chain alliance," forming a layered architecture of "security layer + performance layer." Bitcoin's self-revolution has quietly begun. The OP_RETURN expansion of v30 exposes its ambition of "not wanting to be surpassed," while TBC's benchmark role sets a paradigm of "performance priority under security" for future hard fork projects. When OP_RETURN transforms from a "data shackles" to an "on-chain canvas," and when large blocks transform from a "flood beast" into a "performance cornerstone," a new era belonging to Bitcoin is coming – where the main chain and the forked chain are no longer in competition, but rather a symbiotic and prosperous ecological community.

IV. Inheritance Integration: TBC - The Gene Map of Bitcoin Evolution

The OP_RETURN expansion in Bitcoin v30 appears to be a limited progress of Layer 1, but in fact, it is the prelude to the entire ecosystem moving towards the TBC route. TBC achieves large blocks + UTXO smart contracts + cross-chain interconnection through a hard fork reconstruction, which is essentially the "extreme squeezing" of the Bitcoin main chain within a security framework. The relationship between the two is not competitive but rather a collaborative evolution of "maintaining the main chain's principles and branching out with innovations."

Bitcoin Main Chain: Continue to safeguard the cornerstone of value, meeting basic needs through a combination of Layer 1/2;

TBC public chain: As a tangible carrier of the "Bitcoin smart contract layer," it takes on the banner of high-frequency trading, complex contracts, and cross-chain interoperability, becoming the underlying engine of digital gold liquidity.

In this technological revolution, TBC not only validates the expansion potential of the Bitcoin ecosystem, but also, with its technological advancement and ecological prosperity, quietly becomes a practitioner of the next generation of Bitcoin standards. As Satoshi Nakamoto wrote in the white paper: "We really need a system where its foundational protocol never needs to be modified." TBC embodies this concept through the approach of "forking as upgrading"—TBC is not a traitor to Bitcoin; on the contrary, it is an inevitable product of Bitcoin's evolutionary path.
