Project Dynamics

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

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

At the beginning of its launch, TBC proposed the radical idea of "reconstructing the UTXO model to achieve large blocks + smart contracts," which was seen at the time 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 relying solely on sidechains and middleware could not meet the needs of complex applications. TBC validated 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 an implicit 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 on-chain data potential. TBC's radical innovation once 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 UTXO model naturally adapts to parallel processing, with a 4GB block capacity easily accommodating high-frequency trading, and the BVM architecture enabling near-zero Gas fees for smart contract execution. These traits 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, its loosening of OP_RETURN has already laid the groundwork for future Layer 1 functional enhancements. It is foreseeable that as the Bitcoin main chain gradually unlocks its 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

Although the capacity expansion of Bitcoin v30 has not reached the block limit, its relaxation of OP_RETURN has laid the groundwork for future enhancements of Layer 1 functionality. It is foreseeable 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. From the perspective of technological evolution, 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 upgrade introduced smart contract logic, and Schnorr signatures optimized transaction efficiency, but these patchwork solutions have never been able to break free from the shackles of Layer 2. The emergence of TBC serves as a mirror, reflecting the true needs of the Bitcoin ecosystem—developers crave a development experience comparable to Ethereum within a secure framework, while users require trustless on-chain services. This expansion of OP_RETURN can be seen not so much as Bitcoin's compromise with TBC, but rather as a signal of its proactive embrace of change. In the future, as Bitcoin's Layer 1 functionality gradually strengthens (such as Schnorr signature expansion), its technical path will increasingly converge with TBC: the former continues Satoshi Nakamoto's vision with "phased expansion," while the latter validates technical possibilities with "all-at-once reconstruction," and both will ultimately converge on the consensus of "security first."

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

TBC reconstructs the UTXO model through hard forks, proving that the Bitcoin ecosystem can achieve performance leaps through radical innovation while maintaining security. Its "large blocks + UTXO smart contracts + cross-chain interconnectivity" trinity design provides technological feasibility validation for the OP_RETURN expansion of Bitcoin v30. In the future, Bitcoin's Layer 1 upgrades (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; the 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 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 "data shackles" to "on-chain canvas", and when large blocks transform from "flood beasts" to "performance cornerstones", a new era belonging to Bitcoin is approaching—where the main chain and forked chain are no longer in competition, but rather a symbiotic and prosperous ecological community.

4. Inheritance Integration: TBC - The Genetic Blueprint of Bitcoin Evolution

The OP_RETURN expansion in Bitcoin v30 appears to be a limited improvement on Layer 1, but it is actually the prelude to the entire ecosystem aligning with the TBC route. TBC achieves large blocks through hard forks, +UTXO smart contracts, and cross-chain interconnections, which essentially represents the "maximum extraction" of the Bitcoin main chain within a secure framework. The relationship between the two is not competitive, but rather a collaborative evolution of "the main chain adhering to principles while the forks innovate."

Bitcoin main chain: Continue to safeguard the cornerstone of value by meeting basic needs through Layer 1/2 combinations;

TBC Public Chain: As a concrete carrier of the "Bitcoin Smart Contract Layer", it bears the banner of high-frequency trading, complex contracts, and cross-chain interoperability, becoming the underlying engine of liquidity for digital gold.

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