Solana and TON (The Open Network): A Comparative Analysis of Two Prominent Blockchains

By 2024, Solana and TON (The Open Network) have skyrocketed to prominence in the blockchain world, hitting record-high market caps since their mainnet debuts.

Solana and TON (The Open Network) have emerged as two prominent blockchains in 2024, boasting record-breaking market caps since their mainnet launches. Solana has become a breeding ground for top-tier memecoins, while TON has been the go-to platform for popular crypto “tapping” projects.

Here's a comparative analysis of these two blockchains:

Transaction per second (TPS)

Solana is known for its high transaction processing speeds, with claims of handling up to 65,000 transactions per second (TPS). However, data from Solana's explorer indicates an average TPS of around 3,000, with a total of nearly 300 billion transactions processed to date. This can be partly attributed to Solana's longevity, having been launched in 2017 and undergoing several optimizations over the years.

In contrast, TON's blockchain has a lower TPS, averaging around 100 with a total transaction count exceeding 600 million. A significant portion of these transactions occurred between March 1 and June, corresponding to the deployment of several games on the blockchain, with Notcoin leading the way.

Solana's block time is 0.4 seconds, while TON's is 5 seconds, denoting the time taken to validate a transaction.

Consensus Algorithm

Solana's consensus algorithm combines proof-of-stake (PoS) and proof-of-history (PoH) mechanisms. Validators are chosen based on their stake in the network, and the leader generates a PoH sequence, which is a chronological order of events initiated on Solana. Validators then verify the PoH sequence, create checkpoints, and reach consensus on the order of transactions.

Finally, the leader creates a block based on the consensus, which validators verify and add to the blockchain. Solana also utilizes SHA-256 in its PoH mechanism to measure the creation of blocks with the exact time.

TON employs a variant of PoS called Byzantine Fault Tolerant Proof-of-Stake (BFT-PoS), which enables high transaction speeds and finality while maintaining security and decentralization. Validators are selected based on their staked cryptocurrency, and the consensus process is divided into rounds, with each round having a leader who proposes the next block.

The leader broadcasts the proposed block to other validators, who validate it and vote on its validity. If at least two-thirds of the validators accept the block, it is finalized and added to the blockchain. Otherwise, a new leader is selected and the process repeats. BFT-PoS can tolerate Byzantine faults, where some validators may behave maliciously.

The TON blockchain uses the KECCAK-256 hash function, which is a variant of the SHA-3 hash algorithm. This choice of hash function is a significant design decision for the TON platform, as the hash function plays a crucial role in various security-critical operations within the blockchain.

The choice of KECCAK-256 provides a level, not complete, of compatibility with the Ethereum ecosystem, as Ethereum also uses a KECCAK-based hash function (KECCAK-259) for many of its core operations. This compatibility can be beneficial for developers and users who are familiar with the Ethereum ecosystem and may want to interact with or build applications on the TON platform.

Programming language

Rust and C/C++ are the primary programming languages for developing on the Solana blockchain. Rust is the native and most widely used language for on-chain programs, including smart contracts. Solana was built using Rust, and its team has created a robust set of libraries and tools specifically for building blockchain applications in Rust.

However, Solana also supports Python for client-side development, but not for on-chain program development. Developers can use Python SDKs and APIs to interact with the Solana blockchain from their client applications.

Solana also has community-contributed SDKs that allow developers to use other programming languages, such as Java, Go, and JavaScript/TypeScript, for client-side development and interaction with the Solana blockchain.

FunC is the primary smart contract programming language for TON. Fift is another language that was designed specifically for TON Blockchain. Tact is a high-level language for TON smart contracts similar to TypeScript and Rust. It is developed by the community.

Sharding

Solana does not currently support sharding, which is a technique used to improve the scalability of blockchain networks by dividing the network into smaller, more manageable pieces called shards.

In 2019, Solana CEO Anatoly Yakovenko expressed concerns that sharding could introduce new security risks, such as the potential for a single shard to be taken over by hackers, which could trigger a domino effect and impact the overall security of the network.

However, Firedancer, an independent validator client for Solana, is designing its infrastructure to introduce sharding support on Solana. The goal is to allow the network
