BPoS Staking and Voting Guide
Elastos is updating to a new Elastic Consensus mechanism from which features a novel new Bonded Proof of Stake (BPoS) from the previous Delegated Proof of Stake (DPoS). In late 2021, Yipeng Su, a dedicated contributor to Elastos, proposed the concept of BPoS as a means to enhance the security and stability of both the Elastos main chain and its side chains. BPoS is made up of two groups of participants, stakers and validators. This guide provides steps on how to stake ELA and vote for validators in BPoS.
Included will be:
> Staking and Voting Guidelines
> Getting Started to Stake and Vote
> Steps to Stake and Vote
> Claim Rewards
Staking and Voting Guidelines
♦ In BPoS, users are required to pledge their ELA for at least 10 days or 7,200 block heights, up to a maximum of 1000 days or 720,000 block heights.
♦ One staked ELA can be converted into one equity token which can only be used to vote for one specific node.
♦ The amount of rewards received is determined by the amount of ELA pledged and the pledge time.
♦ Once the vote is set, the pledge time cannot be shortened, but it can be extended. The maximum pledge time for staking on a validator cannot exceed the expected expiration time of the node.
♦ Whenever the pledge time is extended, staking rights and yield rates are recalculated in real-time.
♦ ELA staking profits to the node owners and their stakers is automatically allocated via blockchain code, 25% for the nodes and 75% for their stakers.
♦ 12 CR Council nodes cannot be voted on by stakers.
♦ In DPoS, participants received rewards indefinitely after voting once for their validators. In BPoS, stakers must re-vote once the pledge time (10 to 1000 days) ends to continue earning ELA rewards. To maximize rewards, participants are recommended to set reminders to re-vote.
Download Essentials Wallet
The first step in participating in BPoS is to download the flagship Elastos wallet- Essentials. All BPoS related activities will be done via Essentials. Download the latest version of the wallet on Apple or Android here.
Get ELA on the Mainchain
In order to participate in BPoS consensus, users must have the main chain ELA to stake. Various exchanges such as Coinbase, Kucoin, Huobi, and Gate.io offer access to purchase ELA. Users can also use the Elastos DEX Glide Finance to purchase ELA on the Elastos Smart Contract Chain (ESC). Please refer to the Coingecko Markets page for Elastos for all other options to purchase ELA.
To stake and vote for the validators, the purchased ELA token should be transferred to the Essentials wallet. Once the main chain ELA is received in the wallet, the staking and voting process can begin.
It should be noted that ELA listed on Coinbase is the ERC-20 version and users need to follow this Guide to transfer ERC-20 ELA to mainchain ELA to participate in BPoS.
