Ethereum (79)

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.

Blockchains are usually self-contained systems and lack the ability to communicate with other chains, creating difficulties for users when transferring money. The purpose of building what the crypto space call ‘bridges’ is to address this issue. Through , individuals can efficiently transfer their funds between different chains. Cryptocurrency bridges promote blockchain interoperability and enhance the ease of digital asset transfer. 

Optimism is a popular Ethereum Layer 2 (L2) blockchain designed to increase scalability. As a result, bridging is an essential part of using the technology. Optimism increases efficiency by processing transactions off Ethereum and periodically syncing them. This results in transaction fees and processing speed being significantly lower than Ethereum, making one of the most popular Ethereum L2 solutions. 

Bitcoin and Ethereum stand as the top two cryptocurrencies by market cap today, and have held these leading positions for some time. However, each asset represents a different form of innovation, blockchain philosophy, and use case. 

Solana is a popular competitor to Ethereum, offering high performance and fast transaction speeds. Users can bridge to Solana from Ethereum and other chains to explore its ecosystem. Solana uses a combination of Proof of History (PoH) consensus mechanism alongside Proof of Stake (PoS), to get to a theoretical capacity of 710,000 transactions per second (TPS). Solana’s smart contracts have created a thriving ecosystem of DeFi and NFT marketplaces. 

Arbitrum is a popular Ethereum Layer 2 (L2) solution, making bridging in and out of it essential. Arbitrum uses a method called “optimistic rollup,” where smart contracts are executed off-chain and only the final output is posted to the Ethereum blockchain. It has a significantly larger transaction throughput, making it faster and cheaper than Ethereum. Arbitrum is also an Ethereum equivalent blockchain, making it easy for developers to move their applications from the Ethereum chain.

Blockchains are typically isolated systems and can't interact with other chains, making it inconvenient for users to move funds. Blockchain bridges are built to solve this. Blockchain bridging allows users to move their funds from one chain to another quickly. Cryptocurrency bridges enable blockchain interoperability and make digital asset transfer even more convenient. 

Blockchains are independent networks that cannot communicate with each other. To address this issue, developers have created blockchain bridges . These bridges enable users to seamlessly transfer their funds between different chains. By facilitating blockchain interoperability, cryptocurrency bridges make the transfer of digital assets even simpler. 

Getting familiar with cryptocurrency bridging is essential to your crypto journey. If you’re looking for a detailed guide on how to bridge to Polygon, you’ve come to the right place. Let's explore how to bridge ETH to Polygon using Polygon’s portal and OKX Swap. Additionally, we’ll walk through a centralized bridging process using OKX to bridge USDT from Ethereum to Polygon.

In 2023, thanks to developers like Casey Rodarmor from the Bitcoin dev community, inscriptions became a buzzword in the crypto space. But what are they? Similar to NFTs, you can view them as digital artifacts. Inscriptions are, in short, metadata within the blockchain. For example, if we were to examine , the metadata is encoded on a satoshi, the smallest unit of . For total clarity, ordinals are a means of tracking individual satoshis, which you can attach data to via inscriptions.

Bitcoin ordinals took the Web3 world by storm following their introduction in January 2023. The adoption of ordinals has been massive, with millions of inscriptions being created in the few months since launch.

EigenLayer is an Ethereum-built protocol that supports the restaking of ETH on the blockchain's consensus layer. Through EigenLayer smart contracts, those who stake ETH can provide cryptoeconomic security to other applications across the network.

Authored by Kiwi Yao, researcher @OKX Ventures The simplicity account abstraction (AA) brings to Web3 onboarding has seen the number of registered accounts soar during 2023. That could signal a bright future for Web3's mainstream adoption, as fresh use cases bring others into the latest iteration of the web. But what does the growth of account abstraction look like exactly, and what's caused it's recent emergence?

Chainlink is a blockchain abstraction layer that allows smart contracts to securely communicate with real-world data and services located outside of blockchain networks. It achieves this through a decentralized oracle network. Crucial to the network is , Chainlink's token.

Cross-chain bridges are a powerful force in crypto, allowing for the seamless transfer of your digital assets from one blockchain to another. The tool aims to improve the compatibility of different blockchains, simplifying the transfer of assets between various networks.

Layer-2 (L2) solutions help to enhance Ethereum's scalability, making it more accessible to a larger audience. Two notable L2 options are Optimistic Rollups (OP) and Plasma (POL). OP allows fast off-chain transactions by assuming their validity unless challenged.

As one of the leading platforms for smart contracts and decentralized applications (DApps), Ethereum faces a crucial hurdle that's been hindering it from mass adoption since day one: scalability. As user numbers and network activity rise, transaction speeds slow down and gas fees skyrocket, making widespread use of it difficult during peak transaction periods. However, the upcoming Ethereum Dencun upgrade sparks hope with the introduction of numerous Ethereum Improvement Proposals (EIPs). One such groundbreaking proposal is EIP-4844.

Mantle Network is a pioneering modular Layer-2 solution designed to help scale the Ethereum network efficiently, handling more transactions faster than before. The tool achieves this by bundling transactions together using technology, reducing gas fees and speeding up transaction times.

To many, Decentralized Physical Infrastructure Networks (DePIN) could be a significant catalyst for reshaping how our interconnected world functions. An alternative to traditional centralized systems, DePIN works towards a future where physical infrastructure — from communication networks to energy grids — operates on principles of decentralization. This paradigm shift has the potential to bring about increased robustness, security, and novel possibilities in artificial intelligence (AI), blockchain, and the broader cryptocurrency ecosystem.

Many believe that Polygon 2.0 could significantly change the landscape for decentralized application (DApp) development, opening up DApps to a wider global audience. The latest iteration of the technology is faster, cheaper, and more scalable than ever.

What are inscriptions? Inscriptions are a powerful new method of storing images, videos, audio, text, and code directly on a blockchain. Similar to NFTs, you can view inscriptions as digital artifacts. For example, if we were to examine ordinals, the metadata is encoded on a satoshi, the smallest unit of . Ordinals are a means of tracking individual satoshis, which you can attach data to the blockchain by inscribing them directly on chain.
