The bull run has picked up pace, with $BTC / $ETH taking turns on stage, presenting countless opportunities. The reality, however, is that there are not many projects that can truly turn time into returns. Over the past month, I have been closely watching Nubit / Bitcoin Thunderbolt for a simple reason—it is not just creating another "BTC-like" sidechain, nor is it playing with cross-chain wrapping, but rather it directly incorporates speed and Programmability into the Bitcoin ecosystem, positioning itself as "native upgrade + Soft Fork route." The official upgrade is called Bitcoin Thunderbolt, and the core technology is UTXO Bundling: rather than moving UTXOs on-chain, it instantaneously reallocates the spending rights of a group of UTXOs off-chain through "key tweak," effectively transforming the "single-lane that can only transfer 1 UTXO at a time" into a multi-lane express lane. This approach maintains the trust model of BTC while maximizing speed and throughput—reports from foreign media indicate that the Mainnet has achieved an experience level of ~2.897 seconds per transaction.

Who is doing it and who is endorsing it?

Thunderbolt was initiated by miners, whales, and early contributors from the Satoshi Nakamoto era, with the Nubit team being one of the co-initiators; the project's official channels have also repeatedly emphasized support from Polychain. This combination of "old miners + top funds" is quite sensitive to the consensus of "do not touch the BTC L1 security boundary", so they are taking a cautious route of "soft fork upgrade + gradually relaxing permissions."

Not everyone can enter directly: Boosting Code & Boostpad

The Mainnet is live, but access permissions rely on the "Boosting Code": there are opportunities for a lottery every hour through Boostpad, and actively participating in X/Discord activities and community tasks will also provide batch distributions. The official design goal is very clear: to counter witchcraft and reward genuine active participants. Additionally, when bridging from Thunderbolt to the BTC Mainnet, the official channel clearly states that KYC is required (only for this bridging step). If you are only experiencing and interacting within Thunderbolt, the key is to obtain the Code and stay active. ( Medium)

The real "Yield Panel": Thunderbolt Station (Three Stages)

If the Boosting Code is the ticket to entry, then the Thunderbolt Station is the engine that turns "participation" into "cash flow." The officials break it down into three steps:
Stage 1 Infrastructure: Mint $tsUSD for quota reservation. The amount of $tsUSD you hold determines how much assets can be deposited in the next stage.

Stage 2 Construction: Use the $tsUSD limit in hand to actually deposit assets and start generating site income.

Stage 3 Completion: Daily Settlement, Progress Review, and Earnings Collection.

Income comes from two parts: network transaction fee sharing (you help maintain and expand the network) + the daily output of Boosting Codes (the more you deposit, the more codes the site generates).
As of July 1, 2025, the official data shows: Mainnet 4 million+ transactions, daily active users 5,000+, Boostpad 379,000+ lottery draws, 17,926 verified users - these are not PPT metrics, but concrete evidence of usage on sidechains.

About $tsUSD: Don't treat it as a stablecoin, $tsUSD is your "deposit limit" certificate. Within the Thunderbolt network, $1 of $USD1 or $1 of BTC = 1000 $tsUSD; if you participate on the BTC/BNB chain side, $1 can only be exchanged for 900 $tsUSD (cross-domain participation discount); and the funds used to exchange for $tsUSD are non-refundable, this is a process of "holding space/locking limit." This detail is crucial, don't go All in without understanding it.

How can I participate (subjective approach, for reference only)
I regard Thunderbolt as an "early high-signal native BTC infrastructure," aiming to both seize the experience dividends and create a larger narrative later (Soft Fork, native stablecoin $USD1, on-chain financial primitives). My actions are very restrained, but strong in continuity:
First, get the Code and frequently participate in the Boostpad lottery: without a code, nothing can be discussed. If you can't get it, go to community events to find batch releases.

Make interactions "human-like": transferring, signing, participating in events, answering questions/ranking, with diversified actions + stable frequency, which is more recognizable than mechanically repeating a single action. The threshold design of this project itself focuses on "continuity + quality". (The official documentation clearly explains the "participation methods" and "limited code issuance.")

Understand the "quota logic" of Station as soon as possible: confirm the position you can bear, then mint $tsUSD, occupy the position = obtain the right to store subsequently, do not sacrifice your principal liquidity for a little speed. (Medium)

Use Station as a "cash flow tool": consider two sources: network fee sharing + production code (the code itself is useful in the ecosystem and can bring incremental visits). This is closer to real business than "pure points". (Medium)

Confirm KYC boundaries before bridging: Experience within Thunderbolt does not trigger KYC; to bridge back to the BTC Mainnet, the official Medium states it clearly: KYC is required. Knowing about compliance early means peace of mind. (Medium)

Why do I watch it and not others?

Differentiation on the route: it's neither sidechains/cross-chain bridges, nor wrapping BTC to play elsewhere, but rather the "delegation/reallocation" of UTXO spending rights — which is narratively more "BTC native."
The speed indicator has been disclosed: 2.897s at this level, which at least proves that there is a significant improvement in user experience (media reports + official reiteration). (The Defiant, Medium)
Dual-layer design of issuing codes + site: one hand grabs real activity, and the other hand converts activity into network income/code generation, not just a single "task points".

Risks and Boundaries (Must Read)

Technical and consensus risks: Soft Fork and "UTXO Bundling" belong to a new paradigm, which require time for implementation, auditing, and compatibility verification. (

KYC and Compliance: KYC is only required when you bridge back to the BTC Mainnet from Thunderbolt; regional differences and compliance requirements may affect availability and experience.

The non-refundable nature of $tsUSD: Funds in Stage 1 are non-refundable; this is not a "deposit", but a change in quota. Be sure to weigh liquidity against opportunity cost. (Medium)
Data is a snapshot, not a commitment: figures such as "4 million+ transactions / 5k DAU" are the official figures as of 2025-07-01, only proving temporary popularity, not representing future sustainability. (Medium)
Conclusion (for you who is also looking for the "bull run second curve")

If you're looking for an "early, native, clean rules" BTC opportunity, Thunderbolt is worth keeping an eye on: first take Code, then make small test runs on Station, understand the mechanism before deciding on the depth of your position. Don't be swayed by "get-rich-quick schemes"—treat future experiences and stable activity as part of your strategy; often it is more reliable than "blindly guessing TGE". The above is my subjective approach and does not constitute investment advice; links should only recognize official channels to guard against "customer service/airdrop" phishing.
