Ethernet developers to hold EIP-1559 Gas API call meeting on June 4 at 22:00

The agenda includes a presentation by Gas API providers; JSON RPC endpoints for Gas prices; and an open discussion. Tim Beiko, an Ether developer, commented that one thing to discuss is how to update eth_gasPrice. According to the EIP-1559 wallet call, one would like eth_gasPrice to be backward compatible, so the initial idea is to add a new optional parameter indicating that the caller wants to receive an estimate according to EIP-1599. Another option is that we can add new terminals eth_maxPriorityFeePerGas and eth_maxFeePerGas, which the client can call to get new information.

The Polygon SDK is said to be in two iterations, with the first version allowing developers to create standalone chains that are fully interoperable with the Ether network. In the second Polygon SDK iteration, development teams will be able to create actual Layer 2 protocols that connect directly to the main Ethernet network.

Polygon has a synchronization problem on some nodes Hotfixes have been issued

Officially, Anurag Arjun, co-founder and chief product officer of Polygon, an ethereum scaling solution, issued an update stating that on May 26, a small number of verified nodes on the Polygon PoS network were inconsistent with full node synchronization, and that the chain itself remained resilient and fully operational with no state or other inconsistencies detected. At altitude 5237861, the Heimdall block submitter was down before collecting the prevotes, came back online and started collecting the prevotes from the previous round of voting again, but other verifying nodes had already propagated their prevotes, leading to “incorrectly signed prevotes” for other verifying nodes. ” issue. However, waiting for the commit timeout fixed the issue. The impact of these operations can be seen on the Bor nodes of the affected nodes, where block production and synchronization lag on these nodes. An official temporary hotfix was developed to allow these nodes to synchronize with the network. A more robust fix will be released soon to mitigate this situation. The chain itself is still running and deposits from Ether are working as expected, albeit with a slight delay in some cases.

Polkadot nodes with errors on May 24 resolved

According to official sources, the Polkadot node failed on May 24 due to an out-of-memory (OOM) error in block 5202216. The block contains the on-chain solution for the verifier election, which is usually calculated off-chain and only on-chain if no off-chain solution is submitted. Due to the large number of nominators, the election overflows the memory allocated in the Wasm environment. In preparing an update to address this issue, the validator was asked to temporarily downgrade its node software to a previous version containing the runtime native (non-Wasm) version. The native version is not subject to the Wasm memory allocator. After a downtime of one hour and ten minutes, the network was restored. Later, in block 5203204, several nodes failed due to a “memory root mismatch” error. After investigation, this was due to a different compiler version between the native runtime and the on-chain Wasm runtime. The issue has been resolved and precautions have been taken to prevent future recurrence.

Dfinity Founder: Dfinity to Integrate with Ether

Dfinity founder Dominic Williams announced that Dfinity will begin integrating with Ether, according to a blog post detailing the two phases required to integrate the two networks. By using “proxy” contracts, Internet computer smart contracts will be able to “call” Ethernet smart contracts and return results, and vice versa. But the second phase will take longer, in part because while the Internet Computer is designed to scale as more dapps are built on it, its smart contracts can currently only hold up to 4GB of stored pages, so Ether will have to slice and dice between multiple contracts. “some progress has been made on the code side.”
