We're excited to share our experimental solution on Paying Onchain Gas Fees with a Visa Card

At @Visa, we've been exploring ways to simplify blockchain transactions

Imagine paying for gas fees as easily as buying coffee with your card!

But how did we get here?

🧵👇 We delved into concepts like paymasters, Account Abstraction and the ERC-4337 standard. The result?

A solution that lets users pay onchain gas fees with a Visa card without needing native tokens

Let's dive into the problem we're solving

As blockchain evolves, we're seeing the rise of #appchains & #rollups to address scalability. But there's a catch-they come with tradeoffs

Sharing our research at @Visa, as we delve into the complex world of blockchain, exploring the monolithic and modular designs 🧵👇 Blockchain's promise: Decentralization, transparency, and an open-source nature, influencing industries worldwide

But the quest for perfect scalability, security, and decentralization presents a challenge known as the blockchain trilemma

At @Visa, our goal is to always stay ahead of the curve. We're currently exploring the untapped potential of smart contracts, the future of programmable money and payments. We've recently delved into #AA , enabled by #ERC4337 and the exciting possibilities it opens up 🧵👇 Our experiments with ERC 4337 have focused on two unique use cases, deploying Paymaster contracts to evaluate their utility. We're looking at how these can address real world problems and enhance customer experiences with on-chain interactions

Cryptoeconomics blends cryptography & economics to create new communication, cooperation & organization methods, bringing the "invisible hand" to computation. Its role in blockchain success, particularly in understanding rewards & punishment mechanisms is crucial. Lets dive in!👇 Ethereum's multiple monetary policy adaptations over the years ensure stability & security. The beacon chain launch in 2020, EIP 1559, fee burning mechanism & PoS consensus significantly altered its fee model, changing how network participants are incentivized

Have you ever wondered how blockchains reach consensus and prevent double spending? Our new report at @Visa delves into the world of consensus mechanisms and their implications for blockchain payments. 🧵 We examine the PoW algorithm, the original consensus mechanism used by #Bitcoin. How does it function? Is it the most efficient and sustainable solution for the future of blockchain payments? Does PoW provide more decentralization?

At @Visa, we are excited to share our latest research piece, where we delve into the specifics of "The Merge", its potential ramifications for the blockchain trilemma, and the upcoming blockchain upgrades that we are closely monitoring. PoW -> PoS

The blockchain industry is constantly evolving, and Ethereum has once again proven to be a trailblazer with its recent transition from PoW to a PoS consensus mechanism. This event marked a significant step towards a more scalable and efficient future!
