Project Updates
In October 2025, the Bitcoin Core v30.0 beta was released, quietly lifting the 80-byte limit on the OP_RETURN (Bitcoin scripting 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 v30 transformation of Bitcoin confirms TBC's foresight as the "vanguard of Bitcoin innovation."

1. Technological Convergence: Bitcoin v30's Implicit Replication of TBC's Core Design
At the beginning of TBC's launch, it 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 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 on-chain data potential. TBC's radical innovation has 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, the 4GB block capacity easily accommodates high-frequency trading, and the BVM architecture realizes smart contract execution with near-zero Gas fees. 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 is how to balance them. Although the expansion of Bitcoin v30 did not reach the block limit, its relaxation on OP_RETURN has laid the groundwork for future Layer 1 functionality enhancements. 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 the Technological Boundaries of Bitcoin
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 been oscillating between "conservatism" and "innovation": the Taproot (mainnet) upgrade introduced smart contract logic, and Schnorr (Schnorr signature algorithm) optimized transaction efficiency, but these patchwork solutions have always been unable to break through the shackles of Layer 2. The emergence of TBC is like a mirror reflecting the real needs of the Bitcoin ecosystem—developers desire a development experience comparable to Ethereum within a secure framework, and users need trustless on-chain services. This expansion of OP_RETURN is less a compromise of Bitcoin towards TBC than it is a signal of its active embrace of change. In the future, as Bitcoin Layer 1 functions gradually enhance (such as Schnorr signature expansion), its technological route will increasingly converge with TBC: the former continues Satoshi's vision through "phased expansion," while the latter validates technological possibilities with "one-step reconstruction," and both will ultimately converge on the consensus of "security first."

3. Future Outlook: TBC - The "Ideal State" of the Bitcoin Ecosystem and the Beacon of the Route
TBC reconstructs the UTXO model through hard forks, proving that the Bitcoin ecosystem can still achieve performance leaps 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, 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 establishes the paradigm of "performance priority under security" for future hard fork projects. When OP_RETURN transforms from a "data shackle" to a "canvas on the chain," and when large blocks change from "a flood beast" to "a cornerstone of performance," a new era belonging to Bitcoin is coming—where the main chain and fork chain are no longer in competition but are a symbiotic and prosperous ecological community.

IV. Inheritance Integration: TBC - The Genetic Map of Bitcoin Evolution
The OP_RETURN expansion of Bitcoin v30 appears to be a limited improvement at Layer 1, but in reality, it is the prelude to the entire ecosystem aligning with the TBC route. TBC achieves large blocks through hard forks, +UTXO smart contracts, and cross-chain interconnectivity, which is essentially the "extreme squeezing" of the Bitcoin main chain within a secure framework. The relationship between the two is not competitive, but rather a collaborative evolution of "maintaining the integrity of the main chain while branching out creatively."

Bitcoin main chain: continue to safeguard the cornerstone of value, meeting basic needs through Layer 1/2 combinations;
TBC public chain: as a concrete 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 has not only verified the expansion potential of the Bitcoin ecosystem but has also quietly become 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 by practicing "forking is upgrading"—TBC is not a traitor to Bitcoin; on the contrary, it is an inevitable product of Bitcoin's evolutionary path.
