Ethereum watchers got three signals in one day: Vitalik Buterin pushed for a simpler protocol, a whale moved roughly $1.8 billion in ETH, and exchange-held supply slid to 2016 levels. Together, the updates put Ethereum’s transparency, liquidity, and wallet behavior back in focus.
Vitalik Buterin calls protocol simplicity an overlooked pillar of Ethereum trustlessness
Ethereum co-founder Vitalik Buterin said the network’s long-term trustlessness depends not only on cryptography and decentralization, but also on how many people can fully understand the protocol. In a post on X on Dec. 17, Buterin wrote that increasing the number of developers and researchers who can follow Ethereum “from top to bottom” remains an important but underrated goal.
He added that Ethereum needs to improve on this front by simplifying its protocol. According to Buterin, complexity limits who can independently verify how the system works, which in turn concentrates understanding among a smaller group of experts.
The comments came in response to a post by developer dogecahedron, who referenced a discussion about following the approach of the tinygrad project by setting a maximum line count for the Ethereum specification. While Buterin did not propose a specific limit, his response signaled support for efforts that reduce unnecessary complexity and make the protocol easier to audit, study, and maintain.
Buterin’s remarks frame protocol clarity as a core component of decentralization, rather than a secondary technical preference.
Whale Moves $1.8B in ETH After Unstaking
Meanwhile, a whale that previously sold billions of dollars in Bitcoin to buy Ether unstaked its Ethereum and moved funds onchain, according to X user TedPillows and a transfers dashboard screenshot he shared.

The post said the wallet moved about $1.8 billion worth of ETH into seven newly created wallets. The screenshot showed several large ETH transfers recorded minutes apart, each flagged as a whale deposit, with values ranging from tens of thousands to more than 160,000 ETH per transaction.
The wallets’ owner remains unconfirmed from public data alone. Still, the sequence suggests active repositioning, since the transfers followed an unstaking claim and then split into fresh addresses within a short window.
Ethereum Exchange Supply Drops to 2016 Lows
Ethereum’s supply held on exchanges has fallen to its lowest level since 2016, according to data shared by X user NekoZ and charted by CryptoQuant. The metric tracks the share of ETH stored on centralized trading platforms compared with total circulating supply.

The chart shows a steady decline in the exchange supply ratio through 2025, while Ether’s price moved with sharp swings over the same period. As exchange balances fell, fewer coins remained readily available for spot trading, which reflects continued withdrawals from centralized venues.
At the same time, the drop suggests more ETH moved into self custody, staking contracts, or long term holding wallets. The data does not explain intent, but it confirms a structural shift in where Ethereum supply sits onchain rather than on exchanges.
