The future of interaction:
personal, certain, and private.  

Seneca is the first blockchain designed to bridge data-heavy apps with privacy, agency, and transactional confidence of Web3. All of SENECA’s code is being built on a foundation, open and transparent.


How can developers use private data in their smart contracts on Seneca, without revealing the user’s data publicly?

Smart contracts on Seneca can interact directly with zero knowledge proofs of private data from private data sources or from the public blockchain state. Users can submit private data in pre-defined credential and zero-knowledge data structures to smart contracts to enable easy processing of private data.

We are also working on truly private, confidential and privacy-preserving on-chain smart contracts through confidential computing integrations with hardware encryption like, for example, Intel SGX.

How can Seneca be faster than other next-generation Layer1 blockchains?

Seneca is written in Rust, by default a very fast programming language, and in the Substrate framework, which is also built for speed and high transaction throughput.On top of that Seneca implements adaptive state and network sharding and on-chain ZSTARK rollups to achieve even higher TPS numbers.

How does Seneca bring private, trusted data to on-chain transactions?

There are multiple components that allow Seneca to include private, trusted data in blockchain transactions:Verifiable credentials allow you to prove your ownership of structured private data.Zero knowledge proofs enable you share certain details about your identity without revealing the underlying data.Private computing let you interact with others (peers, businesses, applications…) and use your private data without ever revealing the data to them.

How can identity data stored on Seneca be accessed and used or integrated into existing dApps or legacy systems?

All user data is privately stored as verifiable credentials in user-owned private ledgers. This data is easily accessible within the SENECA ecosystem through wallets, dApps and smart contracts.To exchange data with Web2 legacy systems (like HTTP APIs) and other Web3 ecosystems (EVM, Polkadot, Cosmos etc…) we are building specialized adapters that let you pull SENECA-issued data into e.g. EVM smart contracts or push data from external sources e.g. HTTP POST requests into the SENECA blockchain and the users’ private ledgers.
