payments chainsI am not an expert on payments, but I have worked in 3/5 of the big banks in Canada, as well as several fintechs building payments rails and moving a lot of money with code — and most recently on high-perf chainswhich is to say I have some opinions on the concept of a high-perf chain for paymentsthis will be a long post so I suggest clicking the grok button on the top rightfirst, how can a blockchain have a payments focus in the first place?in the past, there have been several approachesone i ...

RT Matt Huang (@matthuang)On Tempo, permissionlessness, L1 vs L2Tempo will be a permissionless chain. On day 1, anyone will be able to deploy a token, and anyone will be able to transact on the chain. Some projects think that attracting real-world usage and serious institutions requires giving up on base layer neutrality. We do not think that, and that's not how we're building Tempo.The plan for Tempo is to have permissionless validation and permissionless smart contract deployment as well as permissionless ...

Tempo's Core Principles - Tempo aims to be a permissionless chain, allowing anyone to deploy tokens and transact from day one [1] - The network plans for permissionless validation, smart contract deployment, and usage, similar to Bitcoin, Ethereum, and Solana, starting with a permissioned validator set for initial operation and gradual decentralization [2] - Tempo will incorporate features to facilitate compliance for entities interacting with the blockchain while maintaining base layer neutrality [3] Rationale for L1 - A decentralized validator set is deemed necessary for global payments to ensure neutrality and foster trust among numerous partners [5] - Building on L1 provides more independence and reduces dependencies on Ethereum L1's progress [6] - Prioritizes fast finality, multiple validators, and custom transaction lanes and gas pricing, which might be complex or slow to implement on an L2 [7] Vision and Goals - The goal is to onboard mainstream entities onto permissionless crypto rails for specific payments needs [4] - The project focuses on building the right product for crypto payments, avoiding crypto tribalism [6] - The company supports permissionless crypto, including Ethereum L1 scaling, L2s, and Bitcoin as a monetary asset, aiming to facilitate real-world payment flows on crypto rails [8]
