The DeFi workshop is on and it kickstarts with @danrobinson giving a keynote about Uniswap V3 :)
Uniswap is a decentralised exchange built using smart contracts. Sort of like the functionality of exchange like a coinbase to allow counter parties to trade assets.
You can trade it directly with the counterparty and everyone maintains custody.
There are plenty of benefits.
You can keep custody of funds - no need to trust someone else to protect them.
Itβs censorship resistance via the base layer. Anyone can transact.
Itβs permissionless - you donβt need a business relationship to use it.
Rollups have empirically demonstrated how to bring down the cost of transacting by 10x-100x.
This is because computation is now local to the rollup and only the data is publicly posted to world.
EIP-4844 can bring down the cost of data, saving us all more on fees.

Data is the single most important resource for any blockchain system including rollups.
The sole purpose of data is to allow anyone to compute a copy of the database that contains:
- Account balances,
- Smart contract code,
- Smart contract state.
Why is that important?
It allows anyone to:
- Review the code of an application (make sure itβs not a scam),
- Check balances and position (in real time),
- Confirm the off-chain system is fully collateralised (assets cover liabilities),
- Be convinced the databaseβs integrity is intact.
