Echo is a network for building smart contracts and decentralized applications that work with Bitcoin and Ethereum.

Introducing Echo

Welcome to the Echo docs! While Echo has been in development for 24+ months, please be aware that it is still early-stage, experimental technology. As such, please note that the current documentation is still being expanded and may change rapidly as new software versions are released. If you see anything you think should be changed, you're welcome to submit a pull request.

What is Echo?

Echo is a network for creating sovereign, decentralized applications that work with Bitcoin. Echo is advancing the usability, flexibility and functionality for smart contracts. Echo includes several main features:

EVM Support

Echo implements the Ethereum Virtual Machine (EVM), allowing you to build smart contracts using Solidity and the tools, libraries and IDEs that support Solidity. You can even port an existing Ethereum decentralized application to Echo with few or no changes required - deploy the exact same bytecode. Read more:

{% page-ref page="technologies/evm-support/README.md" %}

PoWR Consensus

A fast, final and scalable BFT consensus mechanism using Proof of Weighted Randomness (PoWR) also known as EchoRand. EchoRand uses a Verifiable Random Function (VRF) to randomly select a pool of block producers and block verifiers proportionally to their stake to validate each new set of transactions.

x86-64 Virtual Machine

{% hint style="warning" %} Is now in the development stage. {% endhint %}

Echo implements a new, blockchain-specific x86-64 virtual machine allowing developers to write and deploy smart contract in higher level languages. With Echo, smart contracts can be written both in Solidity and in more familiar and convenient languages, such as C, C++, Rust, Go and many more.

Bitcoin and Ethereum Sidechain

Echo implements a Bitcoin and Ethereum sidechains, allowing you to use deposit and withdraw BTC and ETH from the Echo network. Through the sidechain, you can build smart contract and applications that can use BTC and ETH as asset in ECHO, such as decentralized finance (DeFi) applications including stablecoins that are collateralized with Bitcoin and Ethereum.

Current Status

The project is currently under heavy development and testing as early-stage experimental software. Currently, the Echo testnet supports the following actions:

  • Register an account.
  • Participate in the EchoRand consensus.
  • Create and issue new assets.
  • Transfer assets.
  • Deploy and access smart contracts written in Solidity with the EVM.
  • Create and use account addresses.
  • Launch your node and access its API to communicate with the blockchain.

Using Echo

You can start using Echo right now by downloading a wallet to create an account and manage assets using the wallet. The following wallets are currently available:

Use the Echo block explorer to keep track of the blocks and transactions:

To interact with the blockchain as a developer, you have the following libraries and SDKs at your disposal:
