The ledger remembers what the marketing forgets.
On July 20, a Chinese A‑share company named Yangdian Technology (301012.SZ) announced a 5‑year “compute service” contract worth 860 million yuan (≈ $120M). The contract accounts for 67.22% of its 2025 revenue. The counterparty: “Customer A” – an anonymous entity. The location: Sichuan province, once the world’s largest crypto‑mining hub. The timing: three years after China’s “9·24 notice” banned virtual currency mining.
Any analyst who has traced transaction logs from the 2021 Great Mining Migration knows exactly what this means. The contract is not about AI or cloud rendering. It is a carefully worded framework to provide hosting, power, and maintenance for cryptocurrency mining rigs. The question is not whether this is mining – it’s whether the regulators will let it run.

Context: A Lighting Company Turns to “Compute”
Yangdian Technology’s main business is smart lighting and energy‑saving solutions. In 2025, its total revenue was approximately 1.28 billion yuan. The new contract, signed through its subsidiary Sichuan Hanyang Intelligent Technology, promises to deliver an average of 172 million yuan per year for five years. That single client will provide two‑thirds of the company’s top line.
The announcement is short on technical details. No mention of equipment type (GPU? ASIC?), no hash rate target, no proof of existing infrastructure. Instead, the company uses the buzzword “compute service” – a term that sounds legitimate in the age of AI, but in Sichuan with an anonymous counterparty, has one real meaning: bitcoin mining.

Core: The Systematic Teardown
Let’s apply what I learned from auditing the Imperfect Finance protocol in 2020. Back then, a 40% dilution was hidden in the token emission math. Here, the dilution is not in tokens but in risk concentration.
1. The 9·24 Notice is not a suggestion. China’s crackdown on crypto mining in September 2021 was explicit. “Virtual currency ‘mining’ activities” are illegal. Yangdian’s “compute service” is a semantic workaround. If the anonymous client uses the hashing power to mine Bitcoin, Ethereum Classic, or any proof‑of‑work coin, the entire contract operates in a legal gray zone that Sichuan authorities have previously shown a willingness to shut down. I have personally traced funds from a Sichuan‑based mining farm that was raided in 2022 – the shutdown was immediate, and all equipment was seized. The same can happen here.
2. Customer A is a black box. A 860 million yuan contract with an anonymous counterparty is a red flag that would trigger automatic flags in any institutional risk desk. No credit rating, no history, no guarantee of payment. If Customer A defaults after the first year, Yangdian loses 80% of its revenue overnight. The contract might contain early‑termination clauses – but we don’t know. What we do know is that in crypto mining, counterparty risk is usually managed through prepayments or collateral. The absence of disclosure suggests that Yangdian is taking a leap of faith, or that Customer A is an affiliate entity designed to window‑dress the balance sheet.
3. The revenue concentration is a death spiral waiting to happen. 67% of revenue from one client means that any disruption – a government notice, a power outage, a Bitcoin price crash – will cripple the company. In my 2022 FTX forensic report, I showed how a 1.2 billion USD commingled‑funds problem could destroy an entire exchange. Here, the destruction is simpler: one client, one contract, one regulatory letter. “Greed optimizes for yield, not for survival.”
4. The technical feasibility is questionable. Sichuan’s hydropower is seasonal. During the dry winter months, electricity costs spike and availability drops. A 5‑year contract with a fixed monthly fee (implied by the annualized 172M yuan) assumes stable power at a fixed price. Any miner knows that’s unrealistic. The company has no disclosed experience in running large‑scale mining farms. Its balance sheet is not large enough to absorb the capital expenditure required – setting up 50,000 ASIC miners would cost at least 2‑3 billion yuan. Where is the money coming from? Debt? Customer A’s prepayment? The announcement is silent.
Contrarian: What the Bulls Get Right
To be fair, there is a path where this works. If Customer A is a major mining pool willing to provide the equipment and pay a premium for colocation, Yangdian’s risk could be limited to operational cost. The stock market loves narratives. This announcement has already triggered a FOMO rally, and if the first quarterly report shows positive cash flow from “compute services”, the stock could double or triple. Bulls argue that the Chinese government has relaxed enforcement since 2023, and that “compute service” is clever enough to avoid scrutiny.
But this is the same reasoning that believers used before the FTX collapse: “SBF is too smart to fail.” ”Code does not lie, but developers do.” In this case, the code is the contract language – and it deliberately avoids committing to anything verifiable. There is no on‑chain evidence of any infrastructure being built. No genesis block to trace. Only marketing words.
Takeaway: The Accountability Call
Yangdian Technology’s shareholders are buying a lottery ticket with a 67% chance of total loss. The only way to evaluate this contract is to wait for on‑chain proof: a wallet address where mining rewards are deposited, a public audit of the equipment purchase, or a disclosure of Customer A’s identity. Until then, treat this as a speculative instrument, not an investment.
”Trace every byte back to the genesis block.” Without that trace, you are buying a promise – and in crypto, promises are the most expensive asset.
