PART 2
Last time we talked about Layer 2 as Arbitrum, this time its competitor is Optimism. Optimism had been developed by Optimism Foundation, the unlucrative association formed to build Optimism chain especially, and support the ecosystem of Ethereum to the fullest safety net capacity.
.
Optimism uses the Optimistic Roll Up technology as Arbitrum but Optimism uses only main computer called “The Sequencer” to process the heavy data; it doesn’t like the thousands of computers as on the Layer-1. The Sequencer will process the transactions off-chain before sending the successfully processed data back to the Ethereum chain.
.
Optimism has the token called OP, launched on 31 May2022. $OP can be founded on general exchanges such as Binance, Kucoin, Gate.io, Huobi or Bybit.
.
Apart from the fact that Arbitrum and Optimism are developed to support Ethereum chain, both chains can share the co-working space on the DApps among two chains without the difference of building on Ethereum.
