Ethereum scaling startup Optimism has launched a restricted testnet model of its Layer-2 answer.
Aside from ZK-rollups, optimistic is the opposite main answer for sensible contract scalability on Ethereum.
Synthetix Community was the primary DeFi mission to hitch the testnet. Others like Chainlink and Uniswap are following shut behind.

Optimism PBC has launched the primary part of its Layer-2 scaling answer for Ethereum. Main DeFi platforms starting with Synthetix Community, Chainlink, and Uniswap are already lining as much as get pleasure from cheaper and quicker community speeds.
DeFi Tasks Select Optimism
As many DeFi tasks depend on composability with each other, fixed sensible contract calls have been the first purpose for Ethereum’s congestion as of late.
This has led to a rise within the transaction price and lengthy wait instances for a lot of standard functions, even inflicting some to shut down. A rollup provides one answer to this downside.
A rollup executes sensible contracts outdoors of Ethereum and solely makes use of the Layer-1 community to retailer the outcome. The answer reportedly provides a 100x enchancment in transactions per second (TPS) on the Ethereum community.
On Sept. 25, Optimism introduced the primary part of the Optimistic rollup testnet by partnering with the decentralized derivatives trade platform Synthetix.
Synthetix will incentivize individuals with 200,000 SNX (value $990,000 at press time) to make use of the testnet.
Optimistic might be launched in 4 phases, because the Optimistic Digital Machine (OVM) is lastly linked to Ethereum’s mainnet. For now, it should solely cater to minting and burning Synthetix’s stablecoin, sUSD, and claiming the SNX rewards.
Upgrading the DeFi Ecosystem
ZK-rollups and Optimistic rollups are the 2 main options for scaling Ethereum sensible contracts and dApps.
ZK-rollups guarantees to scale Ethereum to 500 tx/sec and leverages non-interactive zero-knowledge proofs (ZK-SNARKs).
Whereas Tether selected ZK-rollups for scaling USDT transactions on Ethereum, the DeFi ecosystem appears to have opted for Optimistic rollups.
In response to Ethereum co-founder Vitalik Buterin, Optimistic rollups are the middleman answer for scaling Ethereum earlier than the launch of ETH 2.0. However, it’s the simpler one to implement with quite a few particular person calls on DeFi sensible contracts.
Kain Warwick, the founding father of the Synthetix, famous in his plans for L2 Synthetix that:
“I strongly consider that the transition of a lot of DeFi to the OVM might be an inflection level the place DeFi is now not a whale recreation, however is accessible to anybody to each construct on and use.”
The opposite main incumbent for Optimism integration is Uniswap. At the moment, the charges for a easy swap on the DEX between Ether and DAI costs greater than $15.
Integrating OVM might carry these charges down and could also be included in Uniswap’s third iteration, Uniswap V3.
