Oracles are the source of truth in DeFi world. They bring the data from the outside world to the blockchain world. Data such as the price of oil barrels or the price of stocks can enable building decentralized applications which leverage such data.
The ERC20 is a standard on which most of the tokens are built and distributed on the Ethereum blockchain. There are new and more advanced standards that are still ERC-20 compatible. Umbrella Network's native token: UMB is ERC20 compatible token.
Staking is the process via which Umbrella holders can delegate their tokens to Validators to earn rewards. Tokens can be staked anytime or unstaked anytime.
Validators bring outside world data and submit it to the Consensus algorithm of Umbrella to earn fees. The financial rewards are aligned such that Validators earn UMB tokens by providing correct data. i.e. the data which is in consensus with other validators and finally accepted.
Slashing is the process via which the Validators who are behaving incorrectly may get penalized to ensure that they are acting correctly. Behaving correctly implies that their data is in sync with other validators.
rUMB1 refers to reward Umbrella tokens which are convertible to Umbrella tokens in a 1:1 ratio after the business goal is achieved or completed of 1 year, whichever is earlier.
