# 4thTech Wiki ## 4thTech Wiki - [Welcome](https://wiki.4thtech.io/welcome.md): Welcome to 4thTech, Web3's first "on-chain" communication building blocks. Technology infrastructure that enables 1000s of "on-chain" communication dApps. - [Getting started](https://wiki.4thtech.io/quickstart/index.md): Learn about immutable on-chain communication, build on top of our protocol stack or utilize the power of our dMail & dChat SDKs & white labels. - [Overview](https://wiki.4thtech.io/architecture/overview.md): Read about 4thTech architecture overview. Designed to be as lightweight and modular as possible while retaining core decentralization primitives. - [Blockchain](https://wiki.4thtech.io/architecture/blockchain.md): We strive to enable access to on-chain communication no matter to the native L1 or L2. - [Storage](https://wiki.4thtech.io/architecture/storage.md): While the SDK integrators can utilize centralized storage, decentralized storage is the key to any modern Web3 solution. - [OCC Protocol](https://wiki.4thtech.io/architecture/protocol.md): With many iterations behind there are six smart contracts forming the core protocol layer. - [Encryption](https://wiki.4thtech.io/architecture/encryption.md): Read about 4thTech encryption overview. - [SDK](https://wiki.4thtech.io/integration/sdk.md): dMail & dChat plug-and-play SDKs stand ready for security-enabled social scaling in the multi-chain universe - [White-label](https://wiki.4thtech.io/integration/white-label.md): dMail & dChat white-label UI stand ready for security-enabled social scaling in the multi-chain universe - [Ethereum](https://wiki.4thtech.io/sdk/ethereum.md): Documentation for the @4thtech-sdk/ethereum package -
