Gravity Bridge (GRAV)

Gravity Bridge is a purpose-built, decentralized, trustless blockchain that bridges assets between the Ethereum and Cosmos ecosystems. Ethereum and EVM compatible tokens can be transferred across the Gravity Bridge to a Cosmos wallet and then onto other Cosmos wallets or DEXs (such as Osmosis or Gravity DEX). Cosmos SDK-based blockchains can similarly send tokens across Gravity Bridge to the Ethereum ecosystem, making them available for transfer or potentially trading on Uniswap or other ETH DEXs.

History

• From their blog (26-8-2021):

"It all started with a Cosmos whitepaper written in 2016, which envisioned an Ethereum Peg-zone as a stand-alone bridge blockchain. The Cosmos ecosystem values many sovereign chains, interconnected through Inter Blockchain Communication. Based on this whitepaper, what would become the Sifchain team, began work on “Peggy” — an Ethereum to Cosmos bridge.

In 2020, a distributed bandwidth platform called Althea started looking into how they could build a bridge between Ethereum and Cosmos chains. They needed stablecoins for their distributed bandwidth network, and they needed them on a sovereign chain to ensure telecom level reliability. Althea created its own design called the Gravity bridge — an Ethereum to Cosmos bridge that focused on simplicity and decentralization. This design had clear value beyond just Althea’s bandwidth network and soon garnered interest from other teams looking for access to Ethereum.

In 2020, Althea and the Iqlusion team partnered to form Peggy JV and together brought funding and development resources to the project. Peggy JV has now evolved to use the bridge software on the Sommelier blockchain, a Cosmos DeFi project.

1. Firstly, Althea that brought the bridge into existence with 70,000+ lines of code, rigorous testing and supporting the bridge across the projects working on it.
2. Next, the Sommelier team, with code improvements, feedback, ergonomic improvements, and testing.
3. The Injective team has also been working on the bridge for their blockchain and has contributed code improvements and bug fixes to the ecosystem."

Token

Token Allocation

• From Citadel (1-4-2022):

"Gravity Bridge launched with a decentralized validator set and roughly half of the tokens allocated to community DAO discretion for airdrops, future ecosystem support, and liquidity mining. It is supported by a community of token holders and validators who will make guiding decisions like the implementation of interchain staking, LM and airdrops."

Utility

• From Citadel (1-4-2022):

"Graviton ($GRAV) is the Gravity Bridge blockchain’s native token. The validators employ $GRAV to secure the bridge."

How it works

• From Citadel (1-4-2022):

"Gravity lets people transfer tokens from Ethereum to Cosmos and back again by locking up tokens on the Ethereum side and minting equivalent tokens on the Cosmos side. Unlike many bridges, Gravity is completely non-custodial — you only need to trust in the security of the Cosmos chain, not some third-party bridge administrators who could run off with your funds."
