Features
Optimistic rollup 
ZK-rollup 
Proof
Uses fraud proofs to prove transaction validity. 
Uses validity (zero-knowledge) proofs to prove transaction validity. 
Capital efficiency
Requires waiting through a 1-week delay (dispute period) before withdrawing funds. 
Users can withdraw funds immediately because validity proofs provide incontrovertible evidence of the authenticity of off-chain transactions. 
Data compression
Publishes full transaction data as calldata to Ethereum Mainnet, which increases rollup costs. 
Doesn't need to publish transaction data on Ethereum because ZK-SNARKs and ZK-STARKs already guarantee the accuracy of the rollup state. 
EVM compatibility
Uses a simulation of the Ethereum Virtual Machine (EVM), which allows it to run arbitrary logic and support smart contracts. 
Doesn't widely support EVM computation, although a few EVM-compatible ZK-rollups have appeared. 
Rollup costs
Reduces costs since it publishes minimal data on Ethereum and doesn't have to post proofs for transactions, except in special circumstances. 
Faces higher overhead from costs involved in generating and verifying proofs for every transaction block. ZK proofs require specialized, expensive hardware to create and have high on-chain verification costs. 
Trust assumptions
Doesn't require a trusted setup. 
Requires a trusted setup to work. 
Liveness requirements
Verifiers are needed to keep tabs on the actual rollup state and the one referenced in the state root to detect fraud. 
Users don't need someone to watch the L2 chain to detect fraud. 
Security properties 
Relies on cryptoeconomic incentives to assure users of rollup security. 
Relies on cryptographic guarantees for security.

Coinbase is a centralized cryptocurrency exchange platform that allows users to buy, sell, convert and store cryptocurrency. Coinbase has features that let you check for prices and trends in the cryptocurrency market through a beginner-friendly user interface.

With over 73 million users across 100+ countries, Coinbase is known to be one of the biggest and most popular crypto exchanges in the world. This article will explain the step-by-step process for how to make your first trade on coinbase.

1. Create a Crypto Exchange Account

Users can trade cryptocurrencies on the Coinbase website and on the Coinbase app, and the process is pretty similar for both methods.

  1. Go to the Coinbase website on your desktop computer (or download the mobile app for Android or iOS)
  2. Click on the Get Started button if you don’t have an account already
  3. Sign in to Coinbase if you have an account
  4. If you don't have an account, create a new account, and go through the different identification process
  5. Add a preferred payment method to enable you to fund your account

Note: common KYC/AML processes for creating new crypto exchange accounts include submitting your contact information and forms of identification such as a photo of your driver's license and a current picture of your face.

2. Click on the Buy or Sell Button

The whole verification process takes about 15 to 20 minutes. After your bank account and identity have been successfully verified you can buy cryptocurrency.

  1. Click on the buy button
  2. Specify the amount of money you want to spend by clicking on the number area
  3. Select the cryptocurrency you want to buy (e.g. Bitcoin)
  4. Double-check the cryptocurrency and the payment method

3. Preview Your Trade

  1. Click on the preview button to check the details of your transaction
  2. If the details are correct, click on the buy now button
  3. Your transaction should go through instantly

The details you want to confirm before clicking "buy now" include:

  • Pay with - the designated payment method
  • Price - the price of the asset
  • Coinbase fee - the fee paid to Coinbase for the transaction, (they charge 1% on all cryptocurrency transactions)

4. Move Your Tokens to a Self-Custody Wallet

Once you have made your trade, it is best practice to move your tokens to a self-custody wallet like Coinbase Wallet and MetaMask. Self-custody wallets are wallets that you own completely, unlike exchange wallets which are custodied by the exchange itself.

The easiest method of transferring tokens on Coinbase to a self-custody wallet is to download the Coinbase Wallet and migrate tokens using the withdraw functionality.
