Blockchain Technology Update for March: Rare BTC Block Reorganization, Ethereum Upgrade …
April 1, 2026
The latest developments in blockchain technology in March highlighted significant advancements and upgrades in both Bitcoin and Ethereum.
Bitcoin Core, the main branch of the Bitcoin client, recently merged the Cluster Mempool update, expected to be a part of the upcoming Bitcoin Core 31.0 version. This upgrade aims to enhance how nodes handle pending transactions by processing related transactions in groups, improving block packaging efficiency and optimizing fee calculations for various transaction types.
Additionally, BTQ Technologies announced the successful deployment of the first functional implementation of Bitcoin Improvement Proposal BIP-360 on its Bitcoin Quantum testnet. BIP-360 aims to address potential quantum computing threats to Bitcoin by introducing a new output type called “Pay-to-Merkle-Root” (P2MR) to minimize exposure risks.
The Bitcoin network encountered a rare two-block reorganization recently, near block height 941,880, where mining pools Foundry USA, AntPool, and ViaBTC experienced a brief fork competition. Despite this event, researchers clarified that such reorganizations are a regular part of Bitcoin’s consensus mechanism and do not indicate any system failure or attack.
In the Ethereum space, significant progress has been made on two key upgrades: the Glamsterdam Upgrade focusing on L1 scaling and MEV fairness and the Hegota Upgrade aiming for censorship resistance, privacy enhancement, and node slimming. Vitalik Buterin emphasized the importance of state tree reconstruction and virtual machine adjustments to improve proof efficiency in Ethereum.
EIP-7864 proposed switching from a hexary Merkle Patricia Tree to a binary tree structure to enhance efficiency and reduce costs in storage access structures. Additionally, EIP-8141 will introduce the Account Abstraction upgrade and the “Frame Transactions” mechanism to enable features like Gas sponsorship and private payments. Virtuals Protocol also introduced ERC-8183 (Agentic Commerce) to establish a standard for AI Agents.
Furthermore, Ethereum introduced a new fast confirmation rule mechanism that allows for quick transaction guarantees with one slot. The Ethereum Foundation outlined future plans for L1 and L2, focusing on maintaining L1 as a global settlement hub and advancing L2 towards different services and security standards.
In terms of Ethereum L2s, Gnosis and Zisk proposed the “Ethereum Economic Zone” framework to encourage collaboration between the mainnet and various Layer 2 networks. Polygon also unveiled the AI tool Agent CLI to support AI agents in wallet creation and fund management on the Polygon chain, offering a range of functions like token sending and swapping.
Overall, the developments in March showcased the continuous evolution and innovation in blockchain technology, particularly in Bitcoin and Ethereum, as they strive to enhance scalability, security, and user experience in the ever-growing digital landscape.
