Echo is a blockchain application development platform and network powered by the integration of Bitcoin and smart contracts. The platform enables efficient decentralized applications for Bitcoin and Ethereum with advanced functionality, flexibility, and usability.

Bitcoin + Smart Contracts

Echo enables FinTech apps, decentralized exchange solutions, derivatives, coins, and more that can all use BTC as native currency.

Develop with Any Language

Echo supports a wide range of tools and languages: Solidity, C++, Go, Python, Rust, and more.


A scalable and efficient mechanism maintains decentralization across every transaction.

Smart Contracts

Unified Development Environment via x64 VM and EVM

Echo provides a convenient environment for smart contracts development with both the x64 Virtual Machine and Ethereum Virtual Machine integrated, enabling complex data structures, algorithms and calculations using any programming language and 3rd party library required for implementation.

Technology Stack

X64 VM

The X64 Virtual Machine supports smart contracts built with major programming languages, frameworks, libraries, compilers, IDEs, and a variety of other tools.


The Ethereum Virtual Machine enables the development of smart contracts in Solidity, providing a unified environment and the ability to easily migrate apps to Echo.

Bitcoin and Ethereum Sidechains

Use Native Currency to Build Powerful DApps

The Echo blockchain is a layer-2 protocol that includes an Ethereum sidechain and a Bitcoin sidechain to enable network interoperability. This unique blockchain protocol enables other blockchain assets, including ERC20 tokens, to be represented on the Echo chain through a bi-directional peg, allowing Echo DApps (e.g., a decentralized exchange) to natively support the assets.

Transfer Process

Transfer of Coins to Echo

A deposit address is created using Echo's create_address operation, and the funds are transferred to that address. These funds are frozen in the source chain, and the corresponding amount of assets is deposited to the Echo chain after voting.

Validation by Voting

Echo's committee members must vote to validate the deposit. The deposit is approved and settled only after the required amount of votes have been casted.

Withdrawal of Coins from Echo

Assets on the Echo chain that are linked to an external chain's coins can be transferred back to its source at any time using the withdrawal operation. This transfer involves the same process of freezing funds, voting, and approval.

PoWR Consensus

Blazing-Fast Proof of Weighted Randomness Consensus

Echo uses a new Algorand-style Proof of Weighted Randomness (PoWR) consensus mechanism. Verifiable random functions (VRFs) are leveraged to select block producers and block validators, enabling consensus to be achieved quickly without a requirement for every node to independently execute all computation, lowering the resources required for each validating node.

Echo's Self-Decentralizing Mechanism

Similar to Bitcoin's difficulty mechanics, Echo sustains decentralization through an efficient mechanism that tracks participation rate and adjusts block creation reward, ultimately attracting more users to the network. This way, Echo always remains decentralized.

Technology Stack

Building DeFi with Bitcoin

Echo allows developers to build decentralized finance (DeFi) apps that integrate with Bitcoin's blockchain and benefit from the performance and flexibility of Echo's advanced smart contract protocol.
