# Technical Architecture

Vince Chain is a scalable Proof-of-Stake blockchain that is fully compatible and interoperable with the Ethereum Virtual Machine (EVM) and Cosmos ecosystem. Vince Chain is built using the [Cosmos SDK](https://github.com/cosmos/cosmos-sdk/) — a blockchain that runs on top of the [CometBFT](https://github.com/cometbft/cometbft) consensus engine—a fork of [Tendermint Core](https://docs.tendermint.com/). 

With the backing of the Cosmos SDK, Vince Chain powers decentralized applications and contracts with fast finality, high transaction throughput, and short block times (\~2 seconds). Vince Chain’s architecture allows users to perform Cosmos and EVM transactions seamlessly and interoperably. Additionally, developers can build communicable and cross-chain Ethereum dApps through the [IBC](https://cosmos.network/ibc), not minding if the network’s tokens and assets come from different independent sources.

Vince Chain enables these key features by

* Adopting and implementing Cosmos SDK [modules](https://docs.cosmos.network/main/building-modules/intro.html) and mechanisms.
* Facilitating dApp interaction with the network using institutional-grade clients and toolings like JSON-RPC, Cosmos gRPC, etc.
* Managing the blockchain on CometBFT's Application Blockchain Interface ([ABCI](https://docs.tendermint.com/master/spec/abci/)).
* Adopting the [geth](https://github.com/ethereum/go-ethereum) library to promote code reuse and maintenance.

With the above features in check, developers can work with the best tools, clients, and API on Vince Chain to build and deploy Ethereum-based applications that are compatible and interoperable with the rest of the Cosmos ecosystem.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://vincechain.gitbook.io/vince-chain-documentation/3.-vince-chain-protocols/technical-architecture.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
