🕹 Technology Blockchain Developers Rollups Crypto
  1. Layer 2 blockchains help scale Ethereum by processing transactions outside of Layer 1.
  2. The OP Stack by Optimism simplifies the deployment of optimistic rollups and is gaining popularity due to Ethereum compatibility, developer-friendliness, partnerships, and the vision for a superchain.
  3. Concerns with the OP Stack include slow transaction finality, potential spikes in transaction fees, lack of sequencer decentralization, and competition from other solutions like Arbitrum.

What's a blockchain?

0 implied HN points • 06 Feb 23
  1. A blockchain is a digital ledger that stores data through transactions, not states.
  2. Blockchains record asset transfers between parties and are decentralized, meaning no single entity controls them.
  3. Different blockchains can be compared based on their technical implementation and financial performance.
