Anatoly Yakovenko: A Deep Dive Into Solana 2.0
In this information-packed episode of Lightspeed, Anatoly Yakovenko, co-founder of Solana, joins us to explore Solana's architecture and roadmap. The discussion covers a wide range of topics, including the Saga Chapter 2, fee market optimizations, Jito and MEV, validator profitability, Solana's end game, Firedancer and client diversity, token extensions, and more. This article provides an in-depth analysis of the key points discussed in the podcast.
Saga Chapter 2: Solana's Mobile Revolution
The Saga smartphone, Solana's foray into the mobile space, has seen a remarkable turnaround in recent weeks. Initially facing slow sales, the project experienced a surge in demand following the rise of the Solana ecosystem and various airdrops. Yakovenko explains the thesis behind the Saga:
"We kind of have this belief that crypto is like new user-generated content. It's digital content that you can transfer and own. So it kind of inherits more rights from the creator because you can force a limited supply and transfer rights and stuff like that into the contracts and make it kind of more interesting for creators."
This approach, however, clashes with traditional app store models, where developers own all the content and are price insensitive to app store fees. The Saga aims to create a new distribution channel for crypto-native content, potentially disrupting the mobile gaming industry, which is currently dominated by Apple and Google's 30% fees.
Yakovenko acknowledges the challenges in building a successful mobile ecosystem but remains optimistic about the potential:
"If we build this phone and we get ecosystem devs to go build experiences, airdrops, whatever, that could get the flywheel going. We'll see though. There's like a lot of ways it could fail."
Solana Fee Market Optimizations
One of the key focuses for Solana's development team is optimizing the fee market. Yakovenko explains the current state of the network and the challenges it faces:
"There's like a bunch of stuff that happens in the lifetime of a transaction before it hits a block producer. And the way that this is solved in like other networks is using a mempool."
Solana's approach differs from traditional mempools, allowing users to submit transactions directly to the leader or a staked node. This design aims to reduce latency but introduces new challenges, such as spam during high-demand periods like NFT mints.
To address these issues, Solana is implementing a Quality of Service (QoS) system that caps the amount of traffic received by leaders:
"With QOS, the leader actually caps the amount of traffic they receive. And I think right now it's at about 100,000 packets per second, which seems crazy, right? Like why do you need to receive 100,000 transactions per second if you only see like 800 actual user transactions land?"
This approach allows for better prioritization of transactions and helps manage network congestion. However, it also introduces new challenges in terms of transaction processing and prioritization.
Jito's Role in Solana's Ecosystem
Jito, a project focused on MEV (Miner Extractable Value) in the Solana ecosystem, has gained significant attention. Yakovenko acknowledges the importance of Jito's work:
"I'm a huge fan of what they're doing. And I think it's like really important that they like continue working on the MEV problem because it's, I think, kind of like both the feature and the bug of all of these systems."
While Jito's approach introduces a mempool-like system to Solana, Yakovenko notes that it's primarily optimized for creating bundles and searchers in DeFi. The challenge lies in scaling this approach to handle high transaction throughput across various use cases.
Scheduler Upgrades: 1.17 and 1.18
Solana is implementing significant upgrades to its scheduler in versions 1.17 and 1.18. These changes aim to improve transaction ordering and reduce jitter in the network. Yakovenko explains:
"Andrew's done a bunch of work to reduce that and make that jitter a lot less kind of, I guess the worst case is to be a lot less bad."
These upgrades are part of Solana's ongoing efforts to improve network performance and reliability.
Dynamic Write Lock Fees
To address network congestion and improve prioritization, Solana is considering implementing dynamic write lock fees. Yakovenko explains the rationale behind this approach:
"If that thing is constantly being saturated, start increasing the write lock fee. And at some point the fee is going to be so high that users are just not willing to pay that fee to sign it."
This mechanism aims to create economic back pressure on saturated accounts, potentially reducing spam and improving overall network efficiency.
Solana Consensus and Formal Verification
When asked about the lack of formal documentation for Solana's consensus mechanism, Yakovenko offers a pragmatic perspective:
"The basically, I think culturally, the engineering team from Solana was like 15 to 20 years out of college. So we just don't even know how to write those papers anymore. We know how to build those systems, but it's just not like I live in my career, I've had one event where I had to rip out a formally verified kernel and put in like a custom system because of performance."
While acknowledging the importance of formal verification for certain contexts, Yakovenko emphasizes the practical approach taken by Solana's team, focusing on real-world testing and performance optimization.
The Value of Client Diversity: Liveness vs Safety
In light of recent events in the Ethereum ecosystem, where a bug in one client implementation caused issues, Yakovenko discusses the importance of client diversity in blockchain networks:
"If you have multiple clients, you have improvements there. But there's also risks simply because four teams spec, a single spec for teams is gonna be four different interpretations."
He emphasizes the trade-offs between liveness and safety, noting that Solana's approach prioritizes safety:
"This is kind of like the trade-offs that you make, I think with liveness leaks and things like that. I don't think Solana would ever have a liveness leak."
Are Solana Vote Transactions Just for Pumping TPS?
Addressing a common misconception about Solana's vote transactions, Yakovenko explains:
"Solana's runtime is so fast that it can handle consensus messages as transactions. That's, it's the opposite."
He argues that the ability to process vote transactions efficiently is a testament to Solana's performance capabilities rather than an attempt to artificially inflate transaction counts.
Solana's End Game
Yakovenko outlines his vision for Solana's future, aiming for a network with over 10,000 nodes and 200-millisecond block times:
"Bitcoin has like about 12,000 nodes and it hit like multi-trillion valuation. So to me that shows that like that node count is sufficient to handle very large value, very large amount of value, right?"
This ambitious goal reflects Solana's commitment to scalability and decentralization while maintaining high performance.
Is Economic Security a Meme?
Challenging the notion of economic security in blockchain networks, Yakovenko argues:
"Economic security is a hangover from like proof of work. Like I think people look at proof of work and the costs to create a heaviest fork. And that does make sense in Bitcoin, but even there, all the operators would reject a rollback deeper than six blocks at this point."
He emphasizes the importance of individual node security and the role of operators in maintaining network integrity, rather than relying solely on economic incentives.
Validator Profitability and Inflation
Addressing concerns about validator profitability and inflation in the Solana ecosystem, Yakovenko offers a nuanced perspective:
"Mathematically, like if you look at the network, inflation is moving value between unstaked users and staked users. And that is a cost to unstaked users, but you can't like, if everyone is equally staked, like I think the staking percentage are now 70%. If everyone is exactly 70% staked and 70% unstaked, no individual person is being diluted because it's literally just moving from one bucket to the other one that they own."
He argues that the focus should be on the overall sustainability of the network, considering both inflation and real-world inputs like transaction fees.
Commoditized Data Layers and L2s
Discussing the potential for layer 2 solutions and data availability layers, Yakovenko expresses skepticism about their long-term value proposition:
"So I think all execution environments are competing, because I think the only way that these systems make money is through selling block space, and that's an execution thing. Like if you're selling data, you're selling a commodity resource, and the pricing and that data is going to approach the cost of the hardware."
He argues that the real value lies in providing specific content and execution environments rather than commoditized data storage.
Firedancer Update
Firedancer, an alternative client implementation for Solana, is making significant progress. Yakovenko shares his expectations for the project:
"A working implementation that is compatible with what's running on mainnet. So we can then start pushing for 50/50 split of stake, running Firedancer and Labs."
He emphasizes the potential for Firedancer to drive improvements in the Solana codebase and potentially increase network capacity:
"What that tells me is not that we should lower the hardware requirements, is that we should figure out if there's bugs in the Labs client that we haven't fixed yet performance bugs and double the capacity of the network."
Solana's New Token Extensions
Formerly known as Token 22, Solana's new token extensions aim to provide enhanced functionality for developers and businesses. Yakovenko explains the advantages of this approach:
"What's really nice about that is that you have a single well-known implementation that everyone has verified and has gotten stressed, tested, and gets robust behaviors that you can plug into a whole bunch of other things that you can build on top."
These extensions offer features like confidential transfers, new metadata options, and increased programmability, potentially opening up new use cases for tokens on the Solana network.
Advice for Solana Founders
When asked about advice for Solana startup founders, Yakovenko emphasizes the importance of focus and perseverance:
"It's just all about focus, like having vision and focus, and surviving long enough until like the market kind of reflects that. And obviously, luck that it reflects it at all."
He recommends reading Paul Graham's essays and Peter Thiel's books for insights on building successful startups in the tech industry.
