The ArbOS V11 proposal has received more than 99% of votes, and Arbitrum's fundamentals will usher in a major change?

Recently, two proposals from Arbitrum have stood out.

On November 28th, the Arbitrum community began voting on the “ArbOS V11” AIP proposal, which stated: "At a high level, the ArbOS upgrade can be considered a hard fork of Arbitrum. 」

ArbOS V11 will pass with over 99% support, what upgrades will Arbitrum usher in?

According to BlockBeats, the proposal currently stands at 99% support, and voting will close at 6 a.m. on December 5. This also means that in the absence of major unforeseen circumstances, the proposal will pass with more than 99% support.

According to the details of the proposal, Arbitrum will receive a number of improvements, including support for the EVM Shanghai upgrade and PUSH0 opcode, as well as various bug fixes. These improvements have now been reviewed for adoption by the Arbitrum Orbit chain, Arbitrum One, and Arbitrum Nova, among others, with the latter two being addressed in the proposal.

In fact, this upgrade to the Arbitrum chain rules is also known as the “ArbOS upgrade”. With the ArbOS upgrade, developers will limit their focus to changes that may alter the validity of Arbitrum blocks (“RBlocks”). This is important to ensure the smooth and secure operation of Arbitrum.

Arbitrum points out that, as with L1’s blockchain ETH, if nodes on a given Arbitrum chain run different versions of ArbOS, this could result in them having two different versions: "Unlike ETH, however, there is an ‘objective’ way to determine which of the two competing chains is the canonical chain: the Arbitrum Bridge. 」

Arbitrum’s bridge is a series of smart contracts residing on its parent chain, and the bridge is responsible for maintaining information about the state of the Arbitrum chain on L1. In addition to that, this enables users to transfer assets between L1 and L2.

The bridge ensures that its perception of the Arbitrum chain is accurate through an assertion and fraud proof system. Arbitrum validators can make claims about the state of the chain, and other validators can question them.

But crucially, this means that L1’s bridge contract needs to understand the execution rules of the Arbitrum chain. Therefore, in the case of Arbitrium One, the updates to these contracts require the Arbitrum DAO to adapt to the changes through a governance proposal that changes the execution rules of the Arbitrum chain.

Therefore, in this proposal, the upgrade of ArbOS is considered an Arbitrum hard fork. Specifically, since the latest version of Geth already includes support for the changes made to the EVM in the Shanghai L1 upgrade, Arbitrum also needs to be supported in sync to ensure that there is no disagreement with the previous version of the node software.

The areas that need to be fixed include retryable fixes, fixing the list of chain owners returned by the precompilation, fixing the issue where some precompiled methods take up all the gas when recovering, creating missing precompiled methods to see some L1 pricing parameters, etc.

Arbitrum’s latest grant proposal: 55 projects share more than $70 million

BlockBeats observed that the Arbitrum community also recently passed a proposal for the allocation of funds.

On December 3rd, the Arbitrum community voted to approve the community proposal to “provide back-up funding for successful STIP proposals”, outlining a one-time rebate for all of Arbitrum STIP’s “approved but not funded proposals”, proposing to increase the total budget by 21.4 million to 71.4 million ARB, while increasing the total number of participating protocols by 26, for a total of 56 funded projects.

On December 4th, the Arbitrum DAO voted on a 21.1 million token ($23.5 million) grant proposal for projects that missed out on the initial 50 million token short-term incentive program (STIP) funding.

In addition to the 29 projects funded in the first round, 26 more projects will be funded, the largest of which is Gains Network, which received 4.5 million tokens ($5 million). Stargate Finance and Synapse will also receive 2 million ARB tokens each ($2.2 million), while Wormhole will receive 1.8 million tokens ($2 million).

With the approval of the new proposal, STIP’s total planned budget has increased to 71.1 million ARB tokens. Under the proposal, additional funds would be allocated after a three-day waiting period.

It is worth mentioning that Wormhole, one of the funded projects, raised $225 million at a valuation of $2.5 billion on November 29, which attracted the attention of the crypto community.
