Ethereum’s centralized dApps may overshadow the decentralization of proof-of-stake

A lively statement connected Reddit Friday resurfaced the treatment of whether the computing infrastructure built connected apical of Ethereum is excessively centralized. According to on-chain data, astir 32% of each Ethereum nodes run connected Amazon AWS servers. However, Amazon claims the fig to beryllium person to 25%.

Morgan Creek co-founder Anthony Pompliano accrued consciousness of the contented successful 2020 erstwhile helium tweeted, “Jeff Bezos could unopen down most… Ethereum-based DeFi apps by simply shutting disconnected AWS.”

Jeff Bezos could unopen down astir of these Ethereum-based “DeFi” apps by simply shutting disconnected AWS.

You’re not decentralized if you conscionable rotation up servers with Uncle Jeff!

— Pomp (@APompliano) October 7, 2020

Since 2020 small has changed regarding the betterment of node decentralization wrong Ethereum. However, Pomp’s tweet is not wholly accurate.

Centralization of Ethereum

The beneath representation shows the percent of hosted Ethereum nodes moving connected AWS. At archetypal glance, this looks highly concerning arsenic it goes against the decentralization communicative successful Ethereum.

Yet, the illustration ignores nodes moving connected backstage machines alternatively of cloud-hosted servers. Hosting work providers facilitate astir 67% of each nodes, and 29% are located successful residential settings.

Interestingly, a stat that is not commonly analyzed is that implicit 50% of the residential nodes tally done a fistful of US-based net providers. Therefore, Verizon, Comcast, Spectrum, and AT&T marque up 51% of the unhosted Ethereum nodes.

Therefore, Amazon, Verizon, AT&T, Spectrum, and Comcast facilitate astir 47% of each nodes connected the Ethereum network. This percent tallies with the full organisation of Ethereum crossed the United States. The US runs astir 5 times the fig of nodes compared to different countries; the adjacent highest successful Germany with 11%.

At 47%, this is precariously adjacent to the often cited magic fig of 51% required to instrumentality down a network. Should a malicious histrion summation entree to the nodes done nefarious successful an onslaught spanning these 5 US companies, they would beryllium susceptible of causing harm to the network.

However, arsenic Dankrad Fried, a researcher astatine the Ethereum Foundation, a 51% onslaught does not springiness an attacker implicit control. They tin inactive origin superior issues;

“They tin halt you from utilizing the chain…[and] revert the chain, i.e. undo a definite fig of blocks and alteration the bid of the transactions successful them.”

A 51% onslaught cannot instrumentality coins from wallets oregon mint caller coins, but reverting transactions tin pb to treble spending, which is simply a important concern.

Will proof-of-stake lick the problem?

The merging of the Ethereum Beacon Chain is the past measurement successful the determination to proof-of-stake for the network. According to the documentation, the lawsuit should pb to a much decentralized ecosystem. There are implicit 400K validators already moving connected Ethereum, each staking astir 32 Ethereum.

Three pools signifier implicit 50% of each staked ETH connected the Beacon Chain; Coinbase, Lido, and Kraken. A akin hazard tin beryllium attributed to these pools arsenic stakers delegate ETH to pools to region the 32 ETH minimum to “unlock a acceptable of validator keys.” Pooling is not disposable natively on-chain, which has led to staking-as-a-service protocols to assistance facilitate a request from smaller investors.

Amazon AWS successful Ethereum

In 2021 Amazon launched Ethereum connected its Amazon Managed Blockchain work to let users to activate an Ethereum node wrong minutes. The familiarity of AWS and its existing integration into galore net processes made this a semi-frictionless acquisition for developers.

A node is integral to immoderate dApp, and the tendency for it to beryllium reliable, secure, and robust is simply a apical precedence for immoderate project. Amazon AWS has garnered the spot and respect of the world’s biggest companies successful web 2, and present it is looking to found akin existent property successful web 3.

The percent of hosted nodes moving connected Amazon AWS has declined astir 3% since 2020, yet it inactive retains a important information with small competition. Upcoming web3 companies specified arsenic Alchemy, Ankr, and others connection a node-as-a-service offering that could theoretically vie with Amazon.

However, galore of these services besides usage Amazon AWS, which lessens their interaction connected decentralization. Companies specified arsenic Gateway.fm are looking to connection a bare metallic server infrastructure to get astir the AWS occupation but are successful the aboriginal stages of development.

The usage of AWS does not connection an inherent hazard to the viability of the Ethereum blockchain. However, it creates a menace should the centralized entities travel nether onslaught to administer the web and origin terrible disruption.
