Korea Blockchain Week, Aug. 8: First-day takeaways from the Cointelegraph team

The first day of the main stage event included a keynote presentation from Ethereum's Vitalik Buterin, 1inch Network's Sergej Kunz, and Klaytn Foundation's Sam Seo.

The fifth annual Korea Blockchain Week kicked off on Aug. 8, with more than 7,000 people attending Asia's largest blockchain event of 2022. 

The Seoul-based event is set to run its main-stage sessions on Aug. 8 and 9, while side events such as music festivals and nonfungible token (NFT) art galleries will go through until Friday, Aug. 12.

This year Korea Blockchain Week features presentations from more than 120 figures in the blockchain space, including prominent names such as Ethereum co-founder Vitalik Buterin, Binance CEO Changpeng Zhao, Animoca Brands chair Yat Siu and Polygon co-founder Sandeep Nailwal.

The event is hosted by FactBlock and Hashed (co-host) and is sponsored by Solana, Klaytn, and Wemade. Key focus topics will include decentralized finance, NFTs, gaming, the Metaverse, Web3 technology and crypto.

If you missed the action, here’s a literary highlight reel of all the most important moments from the first day of the event, brought to you by the Cointelegraph team currently on the ground in Seoul.

Vitalik: Layer-2 scaling will make crypto payments 'make sense' again

Ethereum (ETH) co-founder Vitalik Buterin has argued that crypto payments will once again “make sense” as transaction costs will soon fall to fractions of a cent due to layer-2 rollups.

He pointed to “solid work happening” with roll-ups at the moment, such as Optimism’s layer-2 scaling solution for Ethereum, which has worked to get the size and cost of data in blockchain transactions down by introducing zero byte compression.

“So today with roll-ups, transaction fees are generally somewhere between $0.25, sometimes $0.10, and in the future with roll-ups with all of the improvements to efficiency that I talked about. The transaction costs could go down to $0.05, or even maybe as low as $0.02. So much cheaper, much more affordable, and a complete game changer.”

Web2 adoption key to Metaverse success, says Klaytn Foundation direct

Sam Seo, the director of the metaverse and blockchain ecosystem Klaytn Foundation, thinks that the widespread adoption of the Metaverse will be “easier” if Web2 companies integrate the tech with their products and services.

Speaking with Cointelegraph during the Korea Blockchain Week (KBW), Seo suggested that Web3 Metaverse projects generally have issues attracting a mainstream audience, as people often have a hesitancy to use new technology from companies that they have never heard of.

“If new ideas are combined with Web2 platforms like [local social media app] Kakao, especially in South Korea, I mean, there's accessibility to these new ideas for new services that couldn't be easier than just starting from scratch.”

DeFi market has room for growth in Korea: 1inch co-founder

Decentralized finance (DeFi) aggregator 1inch Network has revealed plans to expand within the Asian market, according to its co-founder Sergej Kunz.

Speaking to Cointelegraph, Kunz said that despite the DeFi market being relatively small in Korea and Asia, there are a number of Asia-based Web3 companies that 1inch is looking to partner with.

However, Kunz also added that the biggest barrier to entry appears to be a lack of understanding about DeFi and how to use crypto wallets:

“As soon as people understand that they can [yield] farm, they can swap, they can exchange and get easy access to cryptocurrencies on Ethereum with a few simple EVM-compatible networks, the market will grow a lot.”

Crypto.com hits key regulatory milestone in South Korea

Crypto exchange Crypto.com has announced a key regulatory milestone in South Korea after acquiring two local companies, giving it access to crypto and payments registration in the country.

The announcement came during Korea Blockchain Week 2022 after the company acquired  payment service provider 'PnLink Co. Ltd.' and virtual asset service provider 'OK-BIT Co. Ltd.'

The move means they have now secured Electronic Financial Transaction Act and Virtual Asset Service Provider Registration in South Korea. However, the company did not disclose whether this means it can offer its full-suite of crypto trading services in the country.

Optimism announces upgrades enabling ‘one-click’ roll-up deployment

As competition between layer-two scaling solutions heats up, Optimism has announced one-click roll-up deployments.

According to a blog post published by Optimism on Sept. 18, the team anticipates Ethereum-native protocols will be able to launch on its network in a single click by the end of October.

“Any tooling that can run on Ethereum will run identically on Optimistic Ethereum,” the post highlighted, adding:

Optimism, the Ethereum Foundation-backed team building developing a layer-two roll-up network, has announced upgrades to its protocol that will enable developers to deploy on its network in just “one-click.”

“Anyone who has written code targeting Geth can now deploy without change — even for advanced features like traces and gas.”

The post asserts that Optimism overhauled its code in a bid to extend beyond Ethereum Virtual Machine (EVM) compatibility to achieve “EVM equivalence” through shrinking the protocol down to its most lightweight and efficient form possible. 

To realize their minimalist philosophy, Optimism’s custom compiler was deleted alongside more than “25,000 lines” of other code as part of the upgrades.

“Building an EVM-compliant rollup poses an even greater challenge: supporting the entire Ethereum stack within the new science,” the post asserts. “Re-implementing security-critical EVM features is costly; every additional line of code introduces the risk of vulnerabilities.”

While the team says it has achieved full EVM equivalence with the Geth Ethereum client, they now hope to facilitate compatibility with alternative node implementations such as OpenEthereum and Erigon with “under 1,000 lines of code.”

Optimism added that no changes have been made to its current security model through the latest release.

Optimism’s progress comes as capital migrates from the Ethereum mainnet to EVM compatible chains and layer-two scaling solutions in a bid to mitigate the high fees associated with transactions executed on Ethereum’s base layer.

According to Dune Analytics, rival rollup network Arbitrum currently boasts the largest Ethereum bridge by total value locked (TVL) with $2.62 billion despite having launched roughly three weeks ago.

Arbitrum is followed by the Polygon ERC-20 Bridge with nearly $2.35 billion, the Avalanche Bridge with $1.86 billion, and the Fantom Anyswap Bridge with $476 million.
