Problem

Decentralized finance has spread its influence on several blockchain networks, including Ethereum, Polkadot, Binance, and many others. Yet, Bitcoin has found it difficult to make headway with DeFi because of its inability to provide the required level of interoperability.

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

Taking into account the challenges outlined above, Echo seeks to ensure top-level interoperability by relying on zero-knowledge proofs which guarantee better efficiency in direct integrations with targeted Layer 1 protocols.

Echo has been developed with the purpose of delivering top performance and more sophisticated use cases. It sets to accomplish these objectives with the help of the following components:

  • 1SVP bridges that provide for liquidity transfers and bring assets from other chains
  • 2Rollup bridges with incentivized state uploads that assist in scaling non-monetary transactions for future Ethereum dApps

Echo in focus

Echo is an advanced Layer 2 network that easily integrates with existing blockchains to provide interoperability and advanced scripting features for crypto assets. It offers a new level of peer communication, enables high-speed asset transfers, and empowers developers to orchestrate high-performing and user-friendly dApps with the ZK rollup bridge connecting to the leading protocols.

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.

  • Solidity logo
  • The icon of x86-64 instruction set

  • 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?

The deposit phase

  • 1

    The user sends a request to receive a deposit address, indicating the sum they’d like to use to top up the balance (e.g. 1 BTC)

  • 2

    The committee locks up the corresponding amount of BTC in ECHO tokens and issues eBTC to the contract address

  • 3

    The user gets the deposit address and makes sure that their locked assets are safe and sound

  • 4

    The user transfers BTC to the received address

  • 5

    The user sends the transaction confirmation to the Echo network

  • 6

    Once the transaction has been confirmed, the user gets the previously locked-up 1eBTC

The withdrawal phase

  • 1

    The user initiates the withdrawal of their funds and locks up the desired sum in the contract

  • 2

    The committee of validators sends the transaction to Bitcoin

  • 3

    The committee directs the transaction confirmation to the Echo network and gets back its locked-up ECHO tokens

  • 4

    If the committee fails to withdraw the funds at a particular time, the user has the ability to unblock the ECHO themselves

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.

Echo FAQs

What is Layer 2 and how is Echo different from other solutions of this type?

  • Layer 2 is used to describe projects and protocols that are created on the basis of existing blockchains. Their primary goal is to provide novel and advanced functionalities and transaction logic mechanisms that will guarantee enhanced efficiency. Examples of Layer 2 solutions include the Lightning Network for Bitcoin and Plasma for Ethereum.

    While many popular Layer 2 solutions focus mainly on off-chain transactions or transfers using a singular asset, Echo links multiple parentchains and enables all functions to interoperate harmoniously on one execution layer. It effortlessly integrates with existing blockchains and provides top scripting features for crypto assets.

Why launch stablecoins on Echo?

  • 1

    The stablecoin will be pegged to Bitcoin

    The collateral obligation resource is provided by eBTC which is a representation of the BTC stablecoin in the Echo network.
    In the Ethereum network, for example, the collateral obligation resource is provided only by its native token ETH.

  • 2

    Absence of intermediate tokens

    When launching a stablecoin on the Echo network, you’ll be exempted from any token conversions, since Echo empowers users to smoothly conduct operations with the existing assets.

  • 3

    The contract system of the stablecoin will be governed by a set of trusted accounts

    The role of an oracle in the Echo network is performed by a special committee which is a set of trusted accounts selected by ECHO holders. These accounts will be responsible for informing the contract system of the current market rate of different coins, such as MKR, DAI, or BTC.

How can Echo assist in building a robust DEX?

  • One of the major benefits of Echo is that it provides for the development of novel and avant-garde decentralized exchanges. Having elaborate sidechains at its core, Echo possesses an infrastructure where all interactions between users and exchanges are totally decentralized and uncompromisingly secure.

    In addition to this, Echo makes use of the decentralized identity functionality which supplies both traders and exchanges with due safety assurances, reduces data vulnerability, and generates unprecedented levels of trust among participants.

How does Echo guarantee the safety of funds?

  • Echo takes advantage of Compound which is one of the largest protocols for loanable funds (PLFs) in terms of locked funds.

    Echo Compound facilitates the creation of liquidation mechanisms via decentralized exchanges and uses the most favorable exchange rates at the time instead of relying on preset ones. Notably, the liquidation calculation mechanism can be smoothly executed on the exchange itself without involving other participants.
