Analysis Reveals Concentration of Bitcoin Control
Recent analysis uncovers that a single unidentified custodian, suspected to be Cobo Custody, holds a significant position in the Bitcoin network. An analyst disclosed that this custodian manages the Coinbase addresses for at least nine mining pools, collectively contributing roughly 47% of the total hash rate. This indicates that out of every 100 newly mined BTC, 47 BTC are directed towards this custodian. Such a concentration of control prompts concerns regarding potential risks and emphasizes the necessity for transparency and decentralization among mining pools regarding custodial arrangements.
Bitcoin Mining Pool Dependence on Singular Custodian
The report highlighted that well-known Bitcoin mining pools such as AntPool, F2Pool, Binance Pool, Braiins, btccom, SECPOOL, and Poolin direct their Coinbase rewards to the same custodian. Additionally, ULTIMUSPOOL and 1THash’s Coinbase addresses are reportedly under the control of this entity as well. Luxor was previously associated with this custodian but altered its setup upon recognizing the reliance.
A Coinbase address serves as an explicit address linked to a mining pool, where the pool’s block rewards are sent upon validating a block of transactions every 10 minutes, resulting in the receipt of 6.25 BTC in the ongoing epoch.
Concerns Regarding Security and Centralization
Recent findings indicate that nearly half of the newly minted BTC is controlled by a single entity, giving rise to potential security vulnerabilities. Should this custodian face a compromise, these mining pools could suffer significant losses, impacting the overall security and sentiment of the network.
In addition to utilizing the same custodian for Coinbase management, the research discovered that these nine mining pools contribute to AntPool’s transaction accelerator service, with the custodian frequently engaging AntPool and ViaBTC’s transaction acceleration services for substantial batch withdrawals. Transaction accelerators aim to expedite the confirmation process of specific transactions, potentially centralizing control over transaction processing, despite offering convenience during network congestion.
Hot Take: Addressing Consolidation in Bitcoin Control
Looking at the analysis of Bitcoin mining pool activities reveals a concerning concentration of control with a singular custodian, raising alarms about security, decentralization, and transparency within the network. This revelation underscores the importance of diverse and distributed custodial arrangements among mining pools to enhance resilience and mitigate risks associated with centralization. As the crypto space continues to evolve, promoting decentralization and fostering transparency will be pivotal in ensuring the robustness and integrity of the Bitcoin network.
