Problem
[object Object]
Ethereum experiences some troubles too. Despite being the mainstay of decentralized liquidity and DeFi, it poses issues such as throughput jams and high gas costs.
All these problems stem from the fact that the majority of existing operability projects focus on generalized interoperability. Thereby, it’s next to impossible to establish their totally smooth functioning within the DeFi ecosystem.

Solution
Echo in focus
[object Object]
Echo welcomes honest partnerships in the blockchain industry and aims to complement parent chains. It is compatible with multiple programming languages, including Solidity, C/C++, Go, Haskell, Python, and Rust.
Key utilities of the Echo network
Parallel architecture
Echo makes use of the Ethereum Virtual Machine (EVM) and supports Solidity-powered smart contracts. This contributes to Bitcoin’s and other asset migrators’ compatibility with the majority of utilities developed on Ethereum. The EVM has been successfully integrated into the Echo ecosystem, which in the long run allowed for complete Web3 support, meaning that smart contracts don’t have to be modified when transferred from the Ethereum network.
Meanwhile, the zero-knowledge rollup (or ZK-rollup) functionality facilitates the scaling of Ethereum-powered apps while recording the history of all actions on the Echo chain and submitting validity proof to the main chain.
Upgraded asset performance
Echo provides network sidechains and token migrators with higher throughput and reduced transaction fees, thereby fostering a better environment for product feasibility. Notably, executing transactions via the Echo sidechain is considerably cheaper than in other protocols, such as renBTC and wBTC.
Modular interoperability
Echo enables Bitcoin, Ethereum, and ERC-20 tokens to securely integrate into the network and leverage prebuilt apps, decentralized exchanges, and other innovative solutions.
Sophisticated permissioning
Echo’s flexible smart contract permission model makes it possible for developers to smoothly deploy custom frameworks within the ecosystem.
Procedural decentralization
Echo sustains decentralization via an efficient mechanism that tracks participation rates and dynamically adjusts block creation rewards to incentivize node diversity.
Supersonic consensus
The network consensus takes just three seconds to perform an operation. The mechanism uses an Algorand-inspired verifiable random function (VRF) to randomly select a pool of block producers and verifiers, prioritizing the highest stakers.
Echo’s mission is to contribute to the integrity of the DeFi ecosystem, provide smooth interoperability between apps launched on different blockchains, such as Ethereum, Polkadot, or Binance, and serve as an advanced instrumental layer between the most significant bridges and Bitcoin.
Outstanding smart contract functionality
Unified development environment via x64 VM and EVM
Echo provides a convenient environment for smart contract development, integrating both the x64 and Ethereum Virtual Machines. The two functionalities together enable complex data structures, algorithms, and calculations, utilizing any programming language and 3rd party library required for implementation. Moreover, Echo permits users to pay fees for the execution of smart contracts deployed in the Echo network in both ECHO and in the protocol’s native tokens, thereby lowering the entry barriers and allowing for general convenience.
Technology stack
EVM
Thanks to the seamless integration of the EVM with the Echo protocol, the transfer of existing Ethereum-based dApps occurs with minimal code changes, which is impossible in other protocols of a similar type.
The Ethereum Virtual Machine also facilitates the development of smart contracts in Solidity, providing a unified environment and tools to easily migrate apps to Echo.
X64 VM
The X64 Virtual Machine supports smart contracts built with major programming languages, frameworks, libraries, compilers, IDEs, and a variety of other tools.
It can also be represented as a layer that can conduct data analysis at a low level, connect trading bots, and even serve as a foundation for building those bots. In addition, this logic can be used for creating new interfaces that would correspond to the requirements of an exchange.
Sophisticated Bitcoin and Ethereum sidechains
The Echo blockchain comes with Ethereum and Bitcoin sidechains that grant better network interoperability. This innovative functionality allows developers to create top-performing DeFi solutions on the high-liquidity protocol and introduce customary contracts into the Bitcoin chain.
Echo's sidechains work through a bi-directional peg. They allow Echo account owners to securely exchange their BTC, ETH, and ERC-20 tokens with the corresponding assets in the Echo network, namely eBTC and eETH. The eBTC/eETH can be used to interact with a smart contract, traded on an exchange, and transferred to another user.

How does the sidechain mechanism function?
Top-performing ZK-rollup functionality
The zero-knowledge rollup is an efficient Layer 2 scaling solution that executes transactions on the Echo chain, yet creates and posts a cryptographic proof (also known as a validity proof) on Layer 1. This functionality helps scale the network and allows for the processing of more transactions.
The ZK-rollup smart contract keeps the data about all transfers on the Echo chain, and it’s only possible to update this data with a special validity proof, rather than any transaction data.
With zero-knowledge rollup, users can validate blocks much faster and more cheaply, since this approach requires less data. Furthermore, there are no delays when moving funds from Layer 2 to Layer 1, since a validity proof accepted by the ZK-rollup contract has already verified the funds.

Blazing-fast proof-of-weighted-randomness consensus
Echo is predicated on the custom EchoRand consensus mechanism.
The primary goal of EchoRand is to reduce the amount of explicit synchronization needed for reaching consensus in a distributed ledger. EchoRand allows for a greater degree of decentralization through the involvement of all users in the consensus process. It produces trust through verifiable randomness and, crucially, delivers top performance by limiting the proportion of users required for consensus in each round.
Echo’s proof-of-weighted-randomness (PoWR) consensus is a Byzantine agreement protocol, where a small committee of block producers (a.k.a. block validators) are chosen randomly from the entire set of network actors. The likelihood of being randomly selected for the committee is proportional to a user’s balance of tokens. Noteworthy is that the committee exists only for a single block, and a new one is randomly chosen for each new block of transactions. The network remains secure as long as at least 33% of tokens are held by honest actors.
Technology stack
Native ECHO token
Echo supports a wide range of assets and tokens, including native assets, sidechain assets, and contract-controlled tokens.
As well as this, Echo possesses its own core asset — the ECHO token — which grants its holders the right to take part in the protocol governance and is used as a type of gas fee currency.
