Avalanche and Solana are leading Ethereum competitors that provide fast, cost-efficient smart contract development environments. Each blockchain is home to a thriving ecosystem of dapps, DeFi protocols, and NFT marketplaces. But what are the differences between Avalanche vs Solana?
In this Avalanche vs Solana article, we’ll compare two of the leading Ethereum competitors. We’ll explore how each blockchain performs, their native assets, and the things to consider before interacting with them. Also, we’ll discuss the throughput, speed, efficiency, cost, smart contract compatibility, and security of each blockchain.
What is Avalanche?
Before we look at the differences between Avalanche vs Solana, let’s take a moment to explore each blockchain. Avalanche is a decentralized layer-one blockchain with smart contract functionality. It was founded in 2020 by Ava Labs and provides a highly-scalable, low-cost alternative to Ethereum, the number-one blockchain for smart contract development. The AVAX token is the native cryptocurrency of the Avalanche blockchain. It plays an essential role in protocol governance and is the primary unit of account throughout the Avalanche network.
Furthermore, the Avalanche blockchain is home to a diverse ecosystem of decentralized applications (dapps), non-fungible token (NFT) marketplaces, and decentralized finance (DeFi) protocols. The network has a transaction throughput of around 4,500 transactions per second (TPS) and a block time of around one second, making it considerably faster than Ethereum. Also, the average transaction fee on Avalanche is around $0.13, making it much cheaper than Ethereum.
Moreover, Avalanche relies on the Snow Proof-of-Stake (PoS) consensus mechanism for transaction validation, which uses a Directed Acyclic Graph (DAG) data structure to enhance speed and efficiency. The platform makes it easy for developers to build, launch, and scale dapps by providing a low-cost, efficient, and stable development environment.
Avalanche vs Solana: The AVAX Token
The AVAX token is the native asset of the Avalanche blockchain. All transaction fees on Avalanche are paid in AVAX, including those associated with smart contract and dapp interactions. Also, AVAX holders can vote on governance proposals to make changes to the underlying protocol. For example, Avalanche governance determines the rate at which new AVAX tokens are minted and the rewards for adding new blocks of transactions to the network.
At the time of writing, the AVAX token is trading at $17.98 with a market cap of 5.6 billion, a circulating supply of 314.5 million tokens, and a total supply of 720 million. The AXAX token is the 17th highest-ranking cryptocurrency by market cap, according to CoinGecko.
What is Solana?
Solana is also a decentralized, highly-scalable layer-1 blockchain with smart contract functionality. The first iteration of Solana’s technology was highlighted in a 2017 whitepaper by Anatoly Yakovenko which outlined the proof-of-history (PoH) concept developed by Solana Labs. The Solana blockchain went live in 2020 and has since become one of the leading Ethereum alternatives for smart contract developers. The project is overseen by the Solana Foundation, a non-profit organization committed to the development of the Solana ecosystem. However, the native SOL token facilitates community governance via on-chain voting.
Furthermore, the Solana blockchain uses a PoS consensus mechanism to validate transitions. However, it optimizes its consensus using the novel PoH timestamping mechanism to make a public timeline of every transaction. PoH allows every node in the network to share a standardized public clock instead of relying on local clocks. Accordingly, Solana nodes don’t have to trust each other to be in sync, and transactions can be ordered more efficiently.
Moreover, Solana is one of the fastest blockchains in existence. It can process up to 65,000 TPS with an average fee of $0.00025 per transaction and an average block time of 400-800ms.
The SOL Token
The SOL token is the native cryptocurrency of the Solana blockchain. It underpins Solana’s PoS consensus mechanism and is essential for governance, interacting with dapps, and paying transaction fees on Solana. At the time of writing, the SOL token is trading at $24.46 with a market cap of $9 billion, ranking as the cryptocurrency with the 11th highest market cap. It has a circulation supply of 371.3 million out of a total supply of 539.3 million tokens. Solana has no fixed supply. Instead, it has an annual inflation rate starting at 8% that will decrease annually until a rate of 1.5% is achieved.
Avalanche vs Solana: Which is Better?
So, Avalanche vs Solana: which is the better blockchain? Both blockchains provide smart contract functionality. As Ethereum competitors, Avalanche and Solana both aim to address the blockchain trilemma of achieving scalability without compromising on security decentralization. However, each network varies in its approach.
Both Avalanche and Solana are faster and cheaper than Ethereum. However, Solana has a higher throughput than Avalanche. Solana can process up to 65,000 TPS with an average of 3,900, whereas Avalanche can process around 4,500 with an average of 20. Solana’s block time of 400-800 ms also trumps that of Avalanche, which is around one second. Furthermore, Solana is generally cheaper than Avalanche. The average transaction fee on Solana is a fraction of a cent. On the other hand, transaction fees on Avalanche usually cost around $0.13.
Architecture and Consensus
The Avalanche network uses three separate chains for optimal performance. Firstly, the Exchange Chain (X-Chain) facilitates asset creation and trading. Secondly, the Contract Chain (C-Chain) takes care of smart contracts and dapps. Finally, the Platform Chain (P-Chain) allows for the creation of subnets and autonomous governance mechanisms. Subnets are secondary networks that operate alongside the Avalanche blockchain. They can be public or private chains with independent validators and governance. However, all subnet validators must support the main Avalanche chain.
Furthermore, Avalanche’s Snow consensus mechanism is an iteration of PoS that promotes efficiency, speed, and decentralization. It uses a leaderless mechanism that bypasses the need for virtual leaders among nodes and allows validators to reach consensus faster than traditional PoS models.
Solana
Solana’s infrastructure comprises eight core components. One of the most innovative features is the Proof-of-History (PoH) “clock before consensus” protocol. PoH provides validators with cryptographic proofs about the ordering of transactions which contributes to Solana’s high throughput. Also, PoH works alongside Solana’s practical byzantine fault tolerance (PBFT) protocol, Tower Consensus. Tower Consensus forms part of Solana’s PoS mechanism and helps to reduce network latency.
Unlike many EVM chains, Solana uses the world’s first parallel smart contracts runtime, Sealevel. Sealevel uses a multi-threaded system that can process smart contract data thousands of times faster than single-threaded alternatives and works in conjunction with the Pipeline transaction processing module for hardware optimization. Also, instead of using mempools, Solana uses the Gulf Stream transaction forwarding protocol.
Additionally, Solana boasts a novel database scaling mechanism called Cloudbreak, a block propagation protocol called Turbine, and a ledger storage mechanism called Archivers. All of these components work together to help the Solana blockchain scale without friction.
Smart Contracts
When it comes to smart contract development, Avalanche is fully EMV-compatible. Ethereum developers can build and deploy smart contracts on Avalanche using standard Ethereum tooling. Solana’s smart contract framework is not natively EVM-compatible. However, the Neon EVM allows developers to run Ethereum smart contracts on Solana.
Building smart contracts on Avalanche is a similar experience to building them on Ethereum. Avalanche dapps are written in the Solidity programming language, making them fully compatible with Ethereum. Ethereum developers can easily migrate smart contracts onto Avalanche and vice versa. However, Solana takes a different approach to smart contract design.
Smart contracts on Solana are called programs. Developers can write Solana programs in Rust, C, and C++. Although this framework is not fully compatible with Ethereum, Rust is a highly-accessible programming language that makes it easy for non-developers to build smart contracts (programs). Also, Solana is becoming increasingly compatible with EVM smart contracts, so there are options available for migrating Ethereum smart contracts to Solana.

Wallets
Avalanche is compatible with MetaMask, the number-one Web3 wallet. MetaMask is the go-to choice for millions of Web3 users. One of the key benefits of MetaMask is that users can use the same wallet to interact with dozens of EVM-compatible chains. When switching between DeFi protocols in different networks, MetaMask enables users to stay within the same wallet application.
Solana isn’t compatible with MetaMask. Several reputable Solana wallets exist. However, you can’t select the Solana network using MetaMask. Switching wallets may not be a significant inconvenience for developers and seasoned investors. Nonetheless, it could pose a barrier to entry for some users.

Decentralization
Both blockchains are managed in part by non-profit organizations. However, each network aims to become community-governed in time. Currently, there are 1,233 validators on Avalanche and 1,874 on Solana. The minimum stake for participating in Avalanche’s Snow PoS consensus is 2,000 AVAX, which equates to around $35,740 at the time of writing. Solana has a significantly lower barrier to entry for participating in PoS consensus with a minimum stake of 0.01 SOL, which is around $0.24.
AVAX vs Solana Fee Structure
Half of all transaction fees on Solana are burned, whereas all fees are burned on Avalanche. Transaction fee burning permanently removes tokens from circulation. Reducing the supply of tokens increases scarcity, often contributing to the perception of increased value among investors. Moreover, Avalanche’s fee-burning model could help the AVAX token become scarce more quickly than SOL. However, token holders who participate in community governance determine the fee structure for each network in the long term.
Investor Confidence
In November 2022, the crypto world was rocked by the collapse of FTX, one of the leading cryptocurrency exchanges. Alameda Research, the venture capital arm of FTX, was heavily invested in SOL. The connection between FTX and Solana caused investor confidence to plummet in anticipation of the bankruptcy that would soon cause FTX to cease trading and pause withdrawals.
This incident resulted in a mass sell-off of SOL. The SOL token lost more than 70% of its market cap in around two weeks. During this period, the SOL token fell sharply from around $38.50 to less than $11. However, investor confidence in the broader crypto market hit a year-long low during this time. Despite this, the AVAX token price only fell by around 44%, indicating stronger investor confidence.
It should be noted that the SOL token has since made somewhat of a recovery. SOL was firmly in the top five cryptocurrencies by market cap ranking before November 2022. However, SOL now trades at around $24.21 and ranks 10th. On the other hand, AVAX is trading at $17.91 and ranks in 18th place.
Network Downtime and Security
The Avalanche network has experienced periods of network congestion since launching. However, the network has never had to pause for any reason. However, the Solana network has been plagued by outages as a result of network congestion and spamming. According to reports, the Solana network has had at least seven partial outages that rendered the blockchain unusable. Although no funds or wallet addresses were compromised, these spamming attacks halted block production on several occasions for multiple hours.
AVAX vs Solana: Summary
Avalanche and Solana are both leading alternatives to Ethereum, the number-one smart contract blockchain. Avalanche and Solana both aim to solve the blockchain trilemma of being scalable without compromising on security or decentralization. Both of these networks offer lower transaction fees and higher throughput than Ethereum. However, Solana has experienced network downtime and a drop in investor confidence.
Solana is one of the fastest blockchains in the world. It has lower transaction fees than Avalanche and also has a lower barrier to entry for participation in consensus. However, both blockchains provide a cost-efficient alternative to Ethereum. With that in mind, Avalanche boasts full-EVM compatibility, whereas Solana uses a unique smart contract programming framework with limited EVM compatibility.
Moreover, both Solana and Avalanche address some of the shortfalls of the Ethereum blockchain. Gas fees on Ethereum often soar during periods of network congestion. Although the Ethereum 2.0 update addresses this, several Ethereum competitors are attracting smart contract developers by offering lower fees and a stable platform for scaling dapps.
