Web3 (345)

Crypto phones  first appeared in 2018. They're smartphones equipped with Web3 connectivity, simplifying access to the decentralized web. Despite recent improvements, mobile Web3 apps can still be less user-friendly than desktop versions, challenging blockchain interactions on smartphones.

On the Solana blockchain, each token or non-fungible token (NFT) resides in its own account, necessitating a deposit of SOL tokens as "rent" to keep these accounts active. This rent mechanism ensures efficient use of network resources and prevents inactive accounts from consuming storage space. However, users can recover the SOL deposited as rent by closing accounts that are no longer needed.

Sometimes, crypto projects with a meme-like concept can evolve to take on a new life with greater utility. One example is Berachain , which began life as the Bong Bears NFT project. At the 2024 edition of Token2049 in Singapore, Berachain’s anonymous co-founder, Smokey the Bera, explained that the team had noticed problems with how a number of blockchain networks worked today. Specifically, they realized that in many cases, liquidity and security weren’t aligned at the chain level. That led to Bong Bears taking on a new life as a Layer-1 blockchain that integrates with the Ethereum virtual machine (EVM). Berachain runs on a Proof of Liquidity (PoL) consensus, which provides security for the chain and rewards participants who provide liquidity.

2023 has already shown itself to be a big year for regulation in crypto, and we’ve not even reached the halfway point. As more nations roll out a regulatory framework for crypto assets, our industry c

Have you hopped on the SocialFi train yet? New Bitcoin City and Friend.tech are two major SocialFi projects that each have a particular focus. New Bitcoin City, with its foundations in the Bitcoin blockchain, is a framework for game players and NFT collectors looking to use beyond just trading on exchanges. Meanwhile, Friend.tech, based on the Ethereum blockchain, is a decentralized social network that allows users to tokenize and monetize their interactions, creating an economic market for social interaction.

What role do decentralized exchanges (DEX) play in today's crypto environment? DEXs allow you to trade digital assets without third-party involvement. Among DEXs, we're witnessing an increase in the usage of crypto perpetual contracts. These contracts are essentially agreements that let traders benefit from asset price movements without the obligation to own or settle the asset. Meanwhile, zero-knowledge proofs (ZK proofs) have been a game-changer in the DeFi space, introducing solutions to privacy and scalability issues.

The crypto industry saw major expansion to all kinds of sectors over the years. Its goal to solve problems doesn't limit it to the problems of the financial industry. One of the industries that the crypto world has expanded into is the video streaming industry. Platforms aiming to offer a decentralized version of YouTube, Twitch, Netflix, and more, are now available.

Authored by Kiwi Yao, researcher @OKX Ventures 2023 was a big year for account abstraction (AA), as the arrival of the ERC-4337 Ethereum standard brought new opportunities for users of the network. ERC-4337 gave access to smart wallet contracts, and its progress since launch has brought new capabilities.

Authored by Kiwi Yao, researcher @OKX Ventures When combined, smart accounts and intent create a powerful tool that allows you to manage your digital assets more efficiently. The ERC-4337 standard enables third parties to process order flows for you. This makes it simpler to carry out tasks while also improving scalability. The alliance between smart accounts and intent paves the way for more advanced interactions in the future.

Authored by Kiwi Yao, researcher @OKX Ventures Multi-chain account abstraction (AA) solutions are a new and innovative way to interact with multiple blockchains. They allow users to create and manage accounts on multiple blockchains without having to worry about the underlying technical details, like having enough of the native tokens for gas payments. This makes it much easier for users to get started with blockchain technology and to use multiple blockchains simultaneously. There are two main types of multi-chain AA solutions: native support and ERC-4337 compatibility.
