It was an thrilling yr for crypto. Decentralized finance (DeFi) took off like a rocket ship, the non-fungible token (NFT) group accelerated ahead and nice strides have been made on blockchain interoperability. The variety of tasks expanded exponentially, groups quickly iterated to discovering product-market match and a wave of latest expertise entered the house to deal with necessary issues hindering blockchains from breaking into the mainstream.
There was one space, nonetheless, that didn’t obtain a lot consideration or enhancements in any respect: scaling. We’re not speaking about scaling the variety of transactions per second or decreasing common charges. There are many groups working throughout layer 1 and layer 2 techniques trying to resolve these issues.
This submit is a part of CoinDesk’s 2020 Yr in Evaluate – a set of op-eds, essays and interviews in regards to the yr in crypto and past. Anatoly Yakovenko is co-founder and CEO of Solana. Raj Gokal is co-founder and COO of Solana.
We’re referring to scaling decentralization or, extra particularly, censorship resistance. The shortage of focus on this space over the previous few years is puzzling provided that censorship resistance is the only most crucial property of blockchain networks.
In 2017, Balaji Srinivasan and Leland Lee revealed a seminal piece titled, “Quantifying Decentralization.” One of many key takeaways from the submit was to measure censorship resistance by the minimal variety of entities required to compromise a essential part of the system. This is named the “Nakamoto coefficient.”
Crypto influencers usually cite the entire variety of nodes, geographic range and the scale of core developer communities as key metrics in figuring out a blockchain’s decentralization. These are all necessary. Nevertheless, probably the most significant issue is the financial distribution between viable nodes in a community. Even a sufficiently decentralized community when it comes to the variety of nodes may very well be corrupted if only some keep monetary management over the decision-making course of.
The highest three Ethereum proof-of-work mining swimming pools at the moment management 51% of the hash energy. The state of affairs isn’t a lot better on proof-of-stake chains. Seven out of the 125 lively Cosmos nodes management over 33% of the entire stake (the brink to mount an assault). On Polkadot, it’s eight out of 258 nodes.
Viewing the present state of blockchains via this lens clearly exhibits the group as a complete hasn’t prioritized scaling censorship resistance.
Whereas this focus of energy could not have an effect on bitcoin for the shop of worth use case, it’s positively problematic for widespread use circumstances on sensible contract blockchains. For instance, these three Ethereum mining pool operators have full management over the ordering of all transfers going out and in of closely used contracts like Uniswap.
We have to scale censorship resistance
They is probably not abusing their energy at present, however giving a small cadre of community members the flexibility to extract worth from one market maker over one other, or one alternate over one other, utterly undermines the explanation why blockchains are helpful in decentralizing finance. The present distribution of energy is not going to work as soon as trillions of {dollars} in worth discovery are being pushed onto public blockchains within the close to future.
And, no, sharding doesn’t remedy the issue. Breaking apart a series into particular person shards doesn’t enhance the system’s general Nakamoto coefficient, and it’s very unclear if random rotation can enhance the safety of a community.
The explanation for surfacing these bleak statistics is to not disparage different blockchains. The fact is identical for Solana, the place the eight largest Solana validators management 33% of the entire stake.
The aim is to spotlight the necessity to innovate in an effort to enhance censorship resistance earlier than it’s too late. Quickly growing crypto costs and the expansion of our ecosystems are elevating the stakes and can entice the eye of skeptical governments, adversarial companies and swarms of incentivized hackers. Our chains’ censorship resistance will likely be examined to ranges not but skilled.
So as to enable DeFi merchandise to draw billions of customers and gadgets, we have to scale censorship resistance. So as to deliver blockchain-based video games to a world viewers, we have to scale censorship resistance. So as to defend our networks towards the huge spectrum of future assaults, we have to scale censorship resistance. It’s the single most necessary drawback to be fixing, and our whole motivation for constructing Solana.

As an business, we have to innovate to incentivize community members to care and contribute, as an alternative of concentrating capital into small teams of validators.
It’s time to refocus on the core subject going through blockchain adoption and sustainability. We hope this submit serves as a name to arms for all blockchain builders and researchers to hitch…
