Solana, Sei & Manta use Parallelism.

Solana, Sei Network, and Manta Network are all blockchain protocols that aim to address the scalability limitations of traditional blockchains. They achieve this by utilizing different techniques, including parallelism, to process transactions more efficiently.

Solana utilizes a combination of Proof-of-History (PoH) and a unique consensus mechanism called Tower BFT to achieve high transaction throughput and low latency. PoH is a verifiable cryptographic clock that allows nodes to agree on the order of transactions without the need for expensive mining. Tower BFT is a Byzantine Fault Tolerance (BFT) protocol that ensures the network remains secure and fault-tolerant even if a small number of nodes are offline.

Sei Network focuses on optimizing transaction execution by batching multiple transactions together and executing them in parallel. This approach reduces the overall transaction processing time and increases the overall network throughput. Sei Network also utilizes a technique called stateless execution, which allows nodes to only store the current state of the blockchain, rather than storing the entire history of transactions. This further reduces the network's resource requirements.

Manta Network utilizes sharding to divide the blockchain into smaller, more manageable shards. Each shard processes transactions independently, which allows for parallel processing and increased transaction throughput. Manta Network also employs a technique called confidential transactions, which encrypts transaction data, protecting user privacy.

All three protocols offer distinct advantages and trade-offs.

Solana's high throughput and low latency make it well-suited for applications that require fast transaction processing, such as decentralized exchanges (DEXs) and real-time gaming.

Sei Network's focus on transaction execution optimization and stateless execution makes it a good choice for applications that require efficient resource utilization.

Manta Network's sharding and confidential transactions make it a good choice for applications that require both scalability and privacy.
