among other stuff, GHO allows position-based minting instead of collateral vault specific minting allowing a smoother and more balanced position management with very heavy gas optimization.
Aave specific features such as emode and portals allows for more use-case and makes GHO easier to integrate outside of L1 or to maintain peg than alternatives.
But i personally be crystal clear on this, the idea is to grow the decentralized stablecoin market not to compete.
The power of DeFi is that GHO allows more liquidity for decentralized stablecoin in the market, more fees for Aave, more volume and fees for Curve, more stability for other stablecoins more attractiveness of DeFi in general compared to CeFi.
With GHO Aave wins, but also curve, balancer, convex, makerdao, qidao, frax and so on…
Synergies define our ecosystem.
