Ethereum projects spend millions securing their own protocols, and almost nothing on shared security. The coordination costs to build shared security infrastructure are tiny compared to the benefits and cost savings that could be had. Griff Green (TheDAO Security Fund) and Josselin Feist (Aave) explore how ecosystem-wide coordination can help overcome this Tragedy of the Ethereum Security Commons.
We spend a fortune on security, yet users still lose money to hacks every day. Security scales beautifully, but its like Ethereum is an apartment building and every project secures it's own apartment but almost nobody is contributing to the building's security. If 20 apartments each install cameras, collectively they pay 10x more for worse coverage than one building-wide system with someone watching it 24/7.
Elinor Ostrom won a Nobel prize for showing how we can use coordination to overcome tragedy of the commons issues almost 20 years ago.
Josselin Feist (Aave) and I think it's time we put this knowledge to work in as an ecosystem and coordinate to secure the Ethereum commons.
