Along with @rjdrost, @NamikMuduroglu, we spent the past two months writing this position paper megaeth.systems/revisitworldco… with comments and feedbacks from @VitalikButerin, @sreeramkannan, @post_polar_, @Austin_Federa, and @megamafia. Personal computers empower individuals to

This week’s upgrade to the MegaETH testnet fixed an elusive performance bug that had caused miniblock time to continuously increase between sequencer reboots. Here’s the story. It’s a story about our philosophy – measure, then build. If one visited MegaETH’s performance

These are some interesting results. It's always nice to see MegaETH comes on top : ) To put the data in some context, the end-to-end latency of an RPC request consists of three components: (1) speed-of-light propagation latency from/to the observer to/from the server, (2) time

MegaETH Official RPC vs Thirdweb RPC – Testnet Latency I wanted to pull direct data from the MegaEth without having to run any infra and was looking for the fastest way to do this. I used "comparenodes.com" to run a simple benchmark to see how MegaETH’s official RPC

And this is how 10ms block time looks like (bottom), even when the user is 100ms away from the server. code for the simulation: github.com/yangl1996/bloc…

Replying to @FigoETH and @Mega_Ecosystem
We aim to provide sub 10ms block times (preconf latency) at launch and plan to reduce to <1ms eventually. Note that e2e latency = block time + network propagation delay. For regular users, the perception of e2e latency will be dominated by their network propagation delay to the

Yesterday’s RPC downtime exposed an interesting edge case. A debug RPC method was invoked in a way that caused the server to allocate a ton of memory for super long strings; the server then went out of memory. It’s been a long time since I last hopped on a call to live-debug

MegaETH’s testnet is now 5 weeks old! With the team focused on cooking the next batch of upgrades, this week’s recap is on the shorter side. This week, the network did not experience any planned or unplanned downtime. The team performed upgrades to the API proxies and the RPC

This week's upgrade of the MegaETH testnet includes an interesting new feature: realtime_sendRawTransaction. This new RPC method sets the foundation for realtime dapp frontends on MegaETH. It solves a simple yet important problem: how to retrieve the receipt of a transaction

No weekly reports for the MegaETH testnet were necessary for the past few weeks because they were pretty uneventful. This week, however, we do have a weekly report, because we had an unplanned maintenance. Here’s a breakdown. On Friday morning ET, our monitor system reported a

MegaETH will soon support paginated reads on the JSON-RPC, starting with logs. It provides a robust API for processing large batches of chain data, which leads to better DevEx and more efficient applications. Here is a quick overview. Objective: Robust Queries over Large Amounts

MegaETH’s public testnet is 1 week old. Here’s what we found and fixed during the first week. The server hosting our public RPC ran out of memory after a curious user sent crafted requests that took large amounts of memory to process. The RPC was down as a result while the

Updating the state root is crazily slow and is responsible for an up to 10x slowdown when building EVM blocks. SALT is MegaETH's solution to this problem. SALT is a brand new authenticated key-value store that replaces (instead of being a mere reimplementation of) EVM's Merkle

MegaETH’s sequencer will soon have hot backups that can be rotated to within tens of milliseconds should the primary sequencer go down. It will boost system reliability and enable downtime-free upgrades. Implementing hot backups for the sequencer is actually quite similar to

Ethereum (the tech and the asset securing the tech) is the ultimate dependency of so much stuff in crypto. MegaETH is a prime example: we have the freedom to push for extreme performance because we settle on Ethereum, the most secure and decentralized L1.
