Optimism is a blockchain solution (now called OP Mainnet) that belongs to the layer 2 category.
A layer 2 is grafted onto a layer 1 (such as Ethereum or Bitcoin ).
In the case of layer 2 Optimism, this is Ethereum.
Its aim is toimprove the performance of layer 1.
Layer 2 solutions are highly sought-after on the market, as they improve the scalability of the main blockchains.
The latter are often too slow to handle the large number of transactions involved in decentralized finance (DeFi), NFT applications and other areas.
This slowness is also reflected in soaring transaction fees.
According to its official website, Optimism has saved the equivalent of $3 billion in gas fees.
In addition to Optimism, the best-known layers 2 on the market today are Polygon, Immutable, Arbitrum and Liquid Network.
In terms of technology, Layer 2 uses rollups.
In the case of Optimism, these areOptimistic Rollups.
The principle behind Optimistic rollups is to group transactions into batches.
These batches are processed off-chain, i.e. outside the main network (in this case, Ethereum).
Once the transactions have been executed, they are verified and registered on layer 1.
To verify transactions, Optimistic rollups use a proof-of-fault protocol.
Before transactions are finally registered on Ethereum, a “contestation” period is opened.
Users can then issue a proof of fraud if any problems are identified.
If fraud is proven, transactions are rejected and the person responsible for the batch is penalized.
The OP token was launched via an ICO on May 31, 2022.
It is used to pay transaction fees and ensure the governance of the DAO. Optimism live share price.

Optimism isone of the largest layer 2s on the market, with over 150 DeFi protocols, including popular ones such as Synthetix, AAVE, Velodrome, Stargate and Uniswap.
The list of projects joining Optimism continues to grow.
Recently, the USDC stablecoin, developed by Circle, landed in its native version on the Optimism chain.
Optimism’s TVL has exceeded $700 million for several months now.
OP’s market capitalization is in excess of 3.2 billion euros, or 30% more than that of Arbitrum, for example.
This capitalization places the OP token in the world’s top 30.
Optimism’s developers are working hard to bring you new solutions.
In 2023, they unveiled the “Superchain” project, as well as a new concept, “the law of chains”.
Plans are also underway to adopt zk rollups on Optimism.

In February 2023, the Coinbase exchange announced the launch of its layer 2 called Base.
This layer 2 is built within Optimism’s Superchain architecture. The Bedrock update.
