TL;DR

• Seismic is an EVM-compatible, privacy-focused blockchain for fintech, characterized by its ability to conceal transaction details by default through TEE and encryption.

• Featuring sub-second finality via its proprietary “Quartz” consensus and native confidential computation capabilities through Seismic Reth, enabling secure on-chain implementation of a wide range of financial products (accounts, lending, payments, etc.).

• Development is accelerating on the back of large-scale funding from firms like a16z, with Brookwell and Cred already adopting the solution. It has earned recognition for its advantages over competitors in ease of development, compliance readiness, and EVM compatibility.

What is Seismic?

Seismic is a privacy-enabled blockchain designed for fintech.

While some additional infrastructure development is required for privacy controls, the core remains EVM-compatible, enabling developers to build smart contracts using Solidity. This achieves confidentiality while minimizing the learning curve for developers.

On the Seismic Chain, transactions and data are encrypted by default to ensure privacy, protecting the contents of all transactions (such as transfers, loans, and swaps).

◼️Technical Composition

We’ll briefly touch on the technical architecture that enables privacy.

As a core technology, it combines data encryption at the protocol level with hardware-based protection. Specifically, it utilizes a Trusted Execution Environment (TEE), ensuring data confidentiality by having all nodes operate within the TEE.

This approach achieves both high privacy and scalability without relying on traditional privacy methods using zero-knowledge proofs (ZK), eliminating the need to develop complex ZK circuits or specialized languages.

Additionally, Seismic natively implements privacy features through its proprietary execution client, “Seismic Reth.” Seismic Reth is a fork of the Rust-based Ethereum client “Reth,” enabling private storage areas, processing of encrypted transactions, and integration with Trusted Execution Environments (TEEs). This allows applications to interact while keeping their state encrypted and enables the execution of smart contract business logic itself in secret.

The chain’s own consensus algorithm is called “Quartz,” a BFT-type consensus that achieves ultra-fast block generation in sub-second intervals.
