The token conforms to the ERC-20 standard and inherits the underlying security of the ETH token. Since ETH is already whitelisted on Bancor and this being wrapped ETH then our security requirements should be met.
Note that most of the liquidity for WETH resides on other DeFi protocols which are using it natively.

ETH doesn't conform to the ERC-20 standard and was released before it existed. In order for DAPPs to be able to use ETH, they have to interact with a representation of ETH that is compatible with the ERC-20 token standard. Most DAPPs opt to use wETH as their base token for their pools for this specific reason. There are steps being taken to make ETH conformant to the ERC-20 token standard in the future.
Ether is used to pay gas fees on every transaction. Once migrated to Eth2, validators will stake the tokens to participate in consensus and receive block rewards.
With the Beacon Chain in production, users can deposit their ETH into the Deposit Contract to claim a validator slot on the Ethereum 2.0 network. Validators have the right to stake ETH on the Beacon Chain to participate in block production and earn staking rewards.
Ethereum operates similarly to Bitcoin through off-chain, informal governance. In this model, developers can submit protocol upgrades, dubbed Ethereum Improvement Proposals (EIPs), on Ethereum's open-source GitHub repository. Core Ethereum developers then discuss new proposals, with additional input from the extended community. If approved by a majority vote, core developers merge the changes into the base code. To avoid complications post-merge, node operators must update their clients to the latest software.
