Q3 2022: Five stories that shaped cryptocurrency

Quarterly retrospective covering July 1–September 30, 2022. Dated September 30, 2022. Stories selected for market impact, policy significance, and consequences for cryptocurrency infrastructure.

1. Ethereum completes the Merge

Ethereum completed the Merge on September 15, replacing proof-of-work block production with the Beacon Chain’s proof-of-stake consensus. The transition ended mining on the main Ethereum network while preserving its transaction history and application state. It was a major engineering milestone and substantially changed how the network was secured and how participants earned protocol rewards. For users and infrastructure operators, the event demonstrated that a widely used blockchain could replace its consensus mechanism; further work on transaction capacity and staking withdrawals remained separate parts of the roadmap.

2. U.S. Treasury sanctions Tornado Cash

The U.S. Treasury announced sanctions against cryptocurrency mixer Tornado Cash on August 8, alleging that it had been used to launder proceeds from major thefts, including activity linked to North Korean actors. The designation immediately sharpened debate over the relationship between financial sanctions, privacy software, and decentralised smart contracts. Infrastructure providers and services had to examine their exposure to listed addresses, while privacy advocates questioned the reach of sanctions against software. The quarter’s development was the designation itself; later litigation and policy changes were still in the future. Source: U.S. Treasury, August 8.

3. Celsius files for Chapter 11 bankruptcy

Celsius filed for Chapter 11 protection on July 13, following its June suspension of customer withdrawals. The filing moved the crisis from an indefinite operational freeze into a court-supervised restructuring, with customers facing questions about asset ownership, creditor priority, and eventual recovery. It was an important next stage in the failure of a business that had offered cryptocurrency-based yields to retail users. Repaying or recovering individual positions did not by itself establish that the company’s overall liabilities could be met or that customers could regain immediate access to funds.

4. Voyager enters bankruptcy as lending contagion spreads

Voyager Digital filed for Chapter 11 on July 5 and announced the move on July 6, becoming another major casualty of the cryptocurrency lending crisis. Its exposure to Three Arrows Capital illustrated how the failure of a trading counterparty could affect a platform used by individual customers. The proceedings made recovery dependent on restructuring and legal processes rather than normal withdrawals. For the wider market, the event underscored that platform balances could represent claims on an interconnected lending business, carrying risks beyond fluctuations in the price of the coins shown in an account.

5. BlackRock connects Aladdin clients to Coinbase Prime

Coinbase announced on August 4 that it was partnering with BlackRock to give eligible institutional clients of Aladdin access to cryptocurrency services through Coinbase Prime, initially focused on bitcoin. The integration covered trading, custody, prime brokerage, and reporting for clients using both platforms. The announcement stood out during a difficult market because a major asset manager was expanding the infrastructure available to professional investors. It represented a service connection for a defined institutional customer group, with practical access depending on the relevant client relationships and platform arrangements.
