BNY plans to route institutional crypto staking through Galaxy's infrastructure once regulators approve it, adding to an existing overlap: Galaxy already stakes Ether for BlackRock's ETHB fund. Ethereum and Solana data show how close a single provider can already sit to the thresholds that control network finality.
BNY's Digital Asset Custody platform will offer institutional crypto staking through Galaxy's infrastructure once regulators approve it, the two firms said Aug. 4. Galaxy already stakes Ether for BlackRock's iShares Staked Ethereum Trust (ETHB) as one of three approved validators, and the fund's prospectus allows it to stake 70% to 95% of its holdings under normal conditions.
The custodian touches roughly 20% of the world's investable assets, with $62.6 trillion in assets under custody and administration as of June 30. Two of Wall Street's largest names now route institutional crypto staking through the same infrastructure provider, and Galaxy also runs staking for Solana and other proof-of-stake networks.
Ownership and control split apart
ETHB's economics and its mechanics sit with different parties: the trust owns the Ether and receives the rewards, but the custodian alone keeps the keys that control withdrawals. Galaxy and the other approved validators run the validation and hold separate validator keys, yet none of them can move the trust's staked ETH on their own.
Why the 33% threshold matters
Ethereum's documentation says validators controlling more than 33% of staked ETH can prevent the chain from finalizing blocks if they go offline or attest incorrectly. A share above 66% can finalize a preferred version of the chain outright. About 33% of ETH's total supply is currently staked, so routing roughly 11% of all ETH through a single provider would already put that provider near the one-third threshold for staked ETH.
Solana's thinner margin
Solana's staking ratio runs much higher, at around 68% of supply, so reaching that same one-third share of active stake there would take about 22.7% of total SOL supply. The network labels the smallest group that can control roughly 33% of delegated stake a superminority. Nakaflow reporting put the Nakamoto coefficient at 10 as of Aug. 5 — the minimum number of validators needed to reach that share.
The Invesco Galaxy Solana ETF filing lists Coinbase Custody as the staking provider and node operator for the fund's SOL, with BNY Mellon acting as administrator.
Shared setups, shared failure points
ETHB's prospectus warns that slashing, inactivity penalties, and correlated penalties across many validators sharing one staking provider could cause losses the trust may never recover from. It cites Ethereum's May 2023 finality disruption as an example. Many institutional validators may run the same client software, cloud region, or key-management vendor, so a single bug can spread across every validator sharing that setup.
An investor holding five institutional crypto brands might assume five separate risks, yet end up backed by the same two or three staking operators throughout.
