Coinbase’s Ethereum staking dominance risks overcentralization: Execs

Coinbase’s emergence as the Ethereum network’s largest node operator raises concerns about network centralization that could worsen as institutional adoption accelerates, industry executives told Cointelegraph. 

On March 19, Coinbase published a report disclosing that the US cryptocurrency exchange controlled more than 11% of staked Ether (ETH), more than any other Ethereum node operator

According to Karan Sirdesai, CEO of Web3 startup Mira Network, Coinbase’s growing dominance highlights “a systemic issue in Ethereum’s staking architecture.”

“We’re creating a system where a handful of major players control an outsized portion of network security, undermining the core promise of decentralization,” Sirdesai told Cointelegraph.

According to the report, Coinbase controlled 3.84 million ETH staked to 120,000 validators, representing 11.42% of staked Ether as of March 4. 

Liquid staking protocol Lido controls a larger share of staked Ether overall — approximately 9.4 million ETH, according to Lido’s website.

However, Lido’s staked Ether is distributed across dozens of independent node operators, Anthony Sassano, host of The Daily Gwei, said in a March 19 post on the X platform.

To limit risks, Coinbase spreads staking operations across five countries and employs multiple cloud providers, Ethereum clients, and relays, according to its report. “Diversification at the network level and the overall health of the network is always a priority for us. That’s why we periodically check network distribution,” the exchange said.

Impending centralization risks

Ethereum’s network concentration could worsen if US exchange-traded funds (ETFs) are permitted to begin staking — a priority for asset managers such as BlackRock.

Coinbase is the largest custodian for US crypto ETFs and holds ETH on behalf of eight of the nine US spot Ether funds, the exchange said in January. 

“This type of network consolidation brings with it increased risk of censorship and reduced network resilience,” Temujin Louie, CEO of Wanchain, a blockchain interoperability protocol, told Cointelegraph. 

For instance, high staking concentrations “represent potential points of regulatory pressure… [and] these large staking entities will likely prioritize regulatory adherence over network censorship resistance when faced with difficult choices,” Sirdesai said.

Meanwhile, new US regulatory guidance allowing banks to act as validators for blockchain networks adds to centralization risks, several crypto executives said.

“If too much stake consolidates under regulated entities like Coinbase and US banks, Ethereum will become more like traditional financial systems,” Louie said. 

Conversely, more institutional validators could actually improve staking concentrations. Cryptocurrency exchange Robinhood is especially well positioned to check Coinbase’s staking dominance, according to Sirdesai.

Robinhood already has “the crypto infrastructure, user base, and technical capabilities to move into staking rapidly. They could realistically challenge Coinbase’s position faster than any traditional bank,” Sirdesai said.

Crypto payments coming to PlayStation as Sony plans stablecoin launch in 2026

Sony Bank, the online lending subsidiary of Sony Financial Group, is reportedly preparing to launch a stablecoin that will enable payments across the Sony ecosystem in the US.

Sony is planning to issue a US dollar-pegged stablecoin in 2026 and expects it to be used for purchases of PlayStation games, subscriptions and anime content, Nikkei reported on Monday.

Targeting US customers — who make up roughly 30% of Sony Group’s external sales — the stablecoin is expected to work alongside existing payment options such as credit cards, helping reduce fees paid to card networks, the report said.

Sony Bank applied in October for a banking license in the US to establish a stablecoin-focused subsidiary and has partnered with the US stablecoin issuer Bastion. Sony’s venture arm also joined Bastion’s $14.6 million raise, led by Coinbase Ventures.

Sony Bank has been actively venturing into Web3

Sony Bank’s stablecoin push in the US comes amid the company’s active venture into Web3, with the bank establishing a dedicated Web3 subsidiary in June.

“Digital assets utilizing blockchain technology are incorporated into a diverse range of services and business models,” Sony Bank said in a statement in May.

“Financial services, such as wallets, which store NFT (non-fungible tokens) and cryptocurrency assets, and crypto exchange providers are becoming increasingly important,” it added.

The Web3 unit, later named BlockBloom, aims to build an ecosystem that blends fans, artists, NFTs, digital and physical experiences, and both fiat and digital currencies.

Sony Bank’s stablecoin initiative follows the recent spin-off of its parent, Sony Financial Group, which was separated from Sony Group and listed on the Tokyo Stock Exchange in September.

The move was intended to decouple the financial arm’s balance sheet and operations from the broader Sony conglomerate, allowing each to sharpen its strategic focus.

Cointelegraph reached out to Sony Bank for comment regarding its potential US stablecoin launch, but had not received a response by the time of publication.
