Evmos

Evmos is an interoperable Ethereum blockchain, built on Proof-of-Stakeproof-of-stake (PoS). It leverages the Cosmos SDK amdand serves as an IBC-compatible EVM-based chain.

The Proof-of-Stake blockchain is compatible and interoperable with Ethereum. It was developed using the Cosmos SDK, which operates atop Tendermint Core consensus engine. Evmos enables the running of vanilla Ethereum as a Cosmos application-specific blockchain. It allows developers to have features of Ethereum, and Tendermint’s PoS implementation. Since it is built atop the Cosmos SDK, it will be able to make exchanges with the Cosmos Ecosystem via the Inter Blockchain Communication Protocol (IBC).

Since it is built atop the Cosmos SDK, it will be able to make exchanges with the Cosmos Ecosystem via the Inter Blockchain Communication Protocol (IBC).

The Evmos blockchain allows Ethereum developers to deploy their smart contracts to the Evmos EVM and use the Proof-of-Stake (PoS) chain. Developers also benefit from clients from testnets that can be used to test and deploy their contracts. It provides built-in interoperability functionalities with other Cosmos and BFT chains by utilizing IBC. Developers can also utilize a bridge network to enable interoperability between the mainnet Ethereum and Evmos.

Evmos''s features enablesenable developers to use existing Ethereum ecosystem tooling and software to deploy smart contracts that interact with the rest of the Cosmos ecosystem. Some mainMain features of Evmos include the following:

• High throughput via Tendermint Core(opens new window)
• Transaction finality

Evmos enables these features by the following actions:

• Implementing Tendermint Core's Application Blockchain Interface (ABCI) to manage the blockchain
• Using modules and other mechanisms implemented by the Cosmos SDK.
• Exposing a compatible Web3 JSON-RPC layer for interacting with existing Ethereum clients and tooling, like Metamask, Remix, Truffle, etc.

Evmos enables compatibility between the Ethereum and Cosmos ecosystems. Each feature is tested and internally audited by the team and then brought to the users.

Validator candidates are able to bond their own staking tokens and have the tokens "delegated,", or staked, to them by token holders. The Evmos is the platform's native token. Evmos plans to launch with 150 validators. The validators are determined by those who have the most stake delegated to them, and the top 150 validator candidates with the most stake become Evmos validators.

Validators and their delegators will get Evmos as block provisions and tokens as transaction fees via the implementation of the Tendermint consensus protocol. Transaction fees will be paid in EVMOS, but later, any token in the Cosmos ecosystem will be valid as fee tender when whitelisted by governance. Validators can set their commission on the fees their delegators get as an extra incentive.

For Validatorsvalidators that double sign, are habitually offline, or do not partake in governance, their staked Evmos, as well as the Evmos of users that delegated to them, can be slashed. The penalty is dependent on the gravity of the violation.

Delegators are required to perform due-diligencedue diligence on validators before delegating, including diversifying by spreading their stake over different validators. Delegators are responsible for choosing validators, and are mandated to remain vigilant and monitor the actions of their validators, in order to switch should they fail to behave responsibly.

The EVMOS is the denomination utilized for staking, governance, and gas consumption on the EVM. It offers the utility of securing the Proof-of-StakePoS chain, it is the token used for governance proposals, distribution of fees to validatorvalidators and users, and also used as gas for operating smart contracts on the EVM. Evmos is compatible with ERC20 tokens and other non-fungible token standards (EIP721, EIP1155) that are natively supported by the EVM.EVMOSEVM. EVMOS asis the base denomination to maintain parity with Ethereum. 1 evmos = 1018 aevmos. This matches the Ethereum denomination of: 1 ETH = 1018 wei.

Voting power is dependent upon stake weight at the conclusion of the 5-dayfive-day voting period, and is proportional to the number of EVMOS participating in the vote. Just bonded EVMOS count towardstoward the voting power for a governance proposal, and liquid EVMOS does not count toward a vote or quorum.

• A minimum deposit of 192 EVMOS is needed for the proposal to enter the voting period, anyone can contribute to the deposit, and it must be reached within 3three days.
• A minimum of 33.4% of the network's voting power is needed to make the proposal valid.
• A majority (more than 50%) of the participating voting power is required to back the Yes vote during the 5-dayfive-day voting period.
• Less than 33.4% of participating voting power votes NoWithVeto.

Inactive validators can cast a vote, but their voting power (including the backing of their delegators) will not count toward the vote if they are not in the active set when the voting period ends. The voting period is currently a fixed 5-day period. During the voting period, participants may select a vote of either Yes, No, Abstain, or NoWithVeto. Voters may change their vote at any time before the voting period ends.

What determines whether or not a governance proposal passes?Currently, the criteria for submitting and passing/failing all proposal types is the same.

There are four criteria:

The denomination used for staking, governance and gas consumption on the EVM is the EVMOS. The EVMOS provides the utility of: securing the Proof-of-Stake chain, token used for governance proposals, distribution of fees to validator and users, and as a mean of gas for running smart contracts on the EVM.Cosmos Coins

Accounts can own Cosmos coins in their balance, which are used for operations with other Cosmos and transactions. Examples of these are using the coins for staking, IBC transfers, governance deposits and EVM.

EVM Tokens, Evmos is compatible with ERC20 tokens and other non-fungible token standards (EIP721, EIP1155) that are natively supported by the EVM.

Evmos uses Atto (opens new window)EVMOS as the base denomination to maintain parity with Ethereum.

Evmos is based on Tendermint Core (opens new window), which relies on a set of validators that are responsible for committing new blocks in the blockchain. These validators participate in the consensus protocol by broadcasting votes which contain cryptographic signatures signed by each validator's private key.

The penalty depends on the severity of the violation.

Delegators are EVMOS holders who cannot, or do not want to run validator operations themselves. Users can delegate EVMOS to a validator and obtain a part of its revenue in exchange (for more detail on how revenue is distributed, see What is the incentive to stake? and What is a validator's commission? sections below).

For Validators that double sign, are habitually offline or do not partake in governance, their staked Evmos, as well as the Evmos of users that delegated to them can be slashed. The penalty is dependent on the gravity of the violation.

Because they share revenue with their validators, delegators also share responsibility. Should a validator misbehave, each of its delegators will be partially slashed in proportion to their stake. This is why delegators should perform due-diligence on validators before delegating, as well as diversifying by spreading their stake over multiple validators.

Delegators include EVMOS holders who cannot, or have no desire to operate validator operations by themselves. Users are able to delegate EVMOS to a validator and get a part of its revenue in exchange. Since they share revenue with validators, delegators share responsibility as well. If a validator misbehaves, each of its delegators will be partially slashed according to their stake.

Delegators play a critical role in the system, as they are responsible for choosing validators. Be aware that being a delegator is not a passive role. Delegators are obligated to remain vigilant and actively monitor the actions of their validators, switching should they fail to act responsibly.

Since it is developed atop the Cosmos SDK, it can exchange value with other aspects of the Cosmos Ecosystem via the Inter Blockchain Communication Protocol (IBC).

Following a botched launch in March 2022, Evmos relaunched in April. The Ethereum Virtual Machine (EVM)-compatible, IBC-enabled blockchain launched in March following a short delay. The blockchain was then inundated by bugs and reports of users struggling to get their airdropped tokens. Following an attempted update, a security vulnerability arose and the blockchain's issues became significant enough for validators to halt the whole chain.

Evmos's founder, Federico Kunze Küllmer, said in an interview:

“We decided as a community of validators and on the core team to just take a step back and try it again once we have everything sorted out.”
