How ZK-rollups Are Changing the Game for Ethereum

Validated Individual Expert

Blockchain technology is designed to provide decentralized and secure transactions, but as more users and transactions are added to the network, the computational burden increases, making transactions slower and more expensive.

ZK-rollups are needed to address the scalability challenges that blockchain networks face.

They are a type of scaling solution for blockchain networks that help to increase the number of transactions that can be processed without compromising the security of the network.

This is achieved by bundling many transactions together into a single batch, or “roll-up,” which is then verified by a smaller set of nodes on the network. The nodes use a technique called zero-knowledge proofs to ensure that the transactions are valid without needing to know the details of each individual transaction. This reduces the amount of computational work needed to process each transaction, making it faster and cheaper to use the blockchain network.

ZK-rollups offer several benefits, including:

  1. Improved scalability: ZK-rollups can process a large number of transactions off-chain and submit them as a single proof to the main chain, significantly increasing the throughput of the network.
  2. Reduced transaction costs: By aggregating multiple transactions into a single proof, ZK-rollups reduce the amount of data that needs to be processed on-chain, leading to lower transaction fees for users.
  3. Increased privacy: ZK-rollups use zero-knowledge proofs to bundle transactions, ensuring that the transaction data remains private and confidential.
  4. Enhanced security: ZK-rollups maintain the security and decentralization of the main chain by ensuring that all transactions are validated by the main chain, preventing fraudulent transactions from occurring within the rollup.
  5. Developer-friendly: ZK-rollups are easy to integrate into existing decentralized applications, allowing developers to scale their applications without requiring significant changes to the underlying code.

  • The Bank of Japan is reportedly planning further interest rate hikes; some officials believe the neutral interest rate will be higher than 1%.

    according to insiders, Bank of Japan officials believe that before the current rate hike cycle ends, interest rates are likely to rise above 0.75%, indicating that there may be more rate hikes after next week's increase. These insiders said that officials believe that even if rates rise to 0.75%, the Bank of Japan has not yet reached the neutral interest rate level. Some officials already consider 1% to still be below the neutral interest rate level. Insiders stated that even if the Bank of Japan updates its neutral rate estimates based on the latest data, it currently does not believe that this range will significantly narrow. Currently, the Bank of Japan's estimate for the nominal neutral interest rate range is about 1% to 2.5%. Insiders said that Bank of Japan officials also believe there may be errors in the upper and lower limits of this range itself. (Golden Ten)

  • HSBC expects the Federal Reserve to refrain from cutting interest rates for the next two years.

    HSBC Securities predicts the Federal Reserve will maintain interest rates stable at the 3.5%-3.75% range set on Wednesday for the next two years. Previously, Federal Reserve policymakers lowered rates by 25 basis points with a split vote. The institution's U.S. economist Ryan Wang pointed out in a report on December 10 that Federal Reserve Chairman Jerome Powell was "open to the question of whether and when to further cut rates at next year's FOMC press conference." "We believe the FOMC will keep the federal funds rate target range unchanged at 3.50%-3.75% throughout 2026 and 2027, but as the economy evolves, as in the past, it is always necessary to pay close attention to the significant two-way risks facing this outlook."
