CL​

• Prysm: No updates.
• Lighthouse No updates.

Mainnet

Audit still ongoing All the clients have created releases Working on Dappnode packages now

Sedge Can we add Erigon? Can we add Nimbus? Probably not

Can we update all the client versions for shapella?

Deposit Contract

We added a executeSystemWithdrawals with the first argument removed. This can be used instead of the one with the deprecated argument if we deprecate Chiado at some point. Alternatively, we can also implement branching logic for Chiado specifically and use that new function for Gnosis mainnet. Needs to be 4 for Chiado for now.

Chain Infra

Gateway: No updates

Chiado

8 withdrawals consume ~45k gas Slot cleanup script done Next step: upgrade to the latest contract version

Hivetest

We solved the warm coinbase issue. Some contracts were missing. Start to look into claim events Building a dashboard, similar to what the EF has To show the test results for different clients https://hivetests.ethdevops.io/ Running the entire suit takes a few hours, so it can sometimes time out on CI GitHub Actions only allows for up to 6 hours This might have been fixed?

Chain Infra

Gateway : Issues with Erigon archival nodes caused by snapshots.Erigon team knows, there’s an issue on GitHub. There is a workaround.

To-do

Shadowfork? There are two observations for Chiado. The state seems to be increasing way faster than before. It might just be related to the withdrawals in blocks, as previously Chiado blocks were mostly empty. Block processing is ~20ms slower. Might also just be linked to withdrawals in blocks. The gas usage is around the same, but system transactions don’t count towards that limit. Might be worth checking this on mainnet with a shadowfork Chiado upgrade Add debug logs to system level transactions to see how much gas they consume. It should be the same for mainnet and chiado Deposit UI: Staking providers, Rocket pool, Stakewise, Etc

Chiado

Storage layout issue? https://github.com/gnosischain/deposit-contract/pull/46 Attach storage layout maps comparison to the PR for clarity

Can Ruben independently check the slot and times so we don’t have the same issue as on Chiado? Test to check if timestamp valid were added on Nethermind

Hive

Coinbase issue There are two checks for the account access cost. Hardcoded value that is failing on pre-shanghai Will check with Mario. On post-shanghai we have warm coinbase due to EIP-3651. So it’s not a blocker for the hard fork at all

Issue with Erigon Marcos is already checking with Andrew

Gateway : Fixed the launchpad.

Withdrawals

GNew contract: https://github.com/gnosischain/deposit-contract/pull/45 Audit in progress Very basic

To-do

• New devnet

  • 50/50 Nethermind + Erigon

• Shadowfork Be careful with the contract upgrades because we can get replayed. What are we trying to achieve with this fork? What are the questions we want to answer? We can also disregard this but spam the devnet with a lot of transactions instead so we have more accurate blocks instead of empty ones. The way it worked for Ethereum. Sync mainnet and stop ELs on some block. Take that hash in the beacon chain genesis. Spin up a new beacon chain with shapella scheduled. We also need to upgrade the contract. We can get replayed. We can also deploy the contracts now. (before the shadow fork) As long as we coordinate around deposit UI changes.

• Upgrade contract on Chiado Deposit UIs

• Mainnet Make sure that enough core devs are available because the holiday season is going to start

Hive

Added more tests to the previous suites. Everything is working. Started to add Erigon, Marcos is in touch with Andrew to fix remaining issues

GNO transfer events issue. Impacted services / tools https://www.notion.so/gnosischain/Scope-3fc9a72e49ab469092403cc931b4aa46

It should definitely be addressed. Solutions - There are a cost for staying ERC20 compliant - Need more research - System lvl Tx that may be added at the end of the block . It should be synced properly. No matter if it will contain all withdrawals or we will create transaction per every withdrawal. It will have its own hash.

OPTION F https://hackmd.io/@dapplion/BJoPtyI82#Option-F-withdraw-contract-pull-distribution Use Aura ‘prioritized’ Tx for withdrawals call This approach considered good and clear

Research

Need to research if Rocket pool might brake by withdrawals issue fix (approach ‘F’) Contact StakeWise

Mainnet

Hardfork is delayed.

Testnet

Don’t need hardfork to for withdrawals issue fix (approach ‘F’)

Research

GNO Transfer events in withdrawals. Needs to be very clearly documented. Has the potential to break things. Explorers and Indexers (how are they extracting withdrawal information right now?)

• The Graph
• Dune

Brainstorming Withdrawals are system transactions Potential solutions: It’s still technically possible to emit receipts, but they wouldn’t be linked to a transaction. It’s fine, but it could break some things. When syncing, we expect the number of receipts to be equal to the number of transactions, but in this case there would be transactions + 1 receipts. Could break JSON-RPC because of existing assumptions. Probably not the best way, but Lukasz doesn’t see any other way.

Inside the node, when someone calls eth_getLogs we could add some artificial logs to GNO based on withdrawals. Would be very hacky. Only on the JSON-RPC level. Might be complicated because of some specific optimizations. Might not be related only to eth_getLogs, because with those logs you should be sure that the withdrawal was applied, which we can’t necessarily do with Gnosis withdrawals. Could work fine without failing withdrawals. We could add a custom transaction that has a receipt for all the GNO transfer events. This would make blocks a bit more specific. Could make it more difficult for block builders. Some more specific code for Gnosis that is different from mainnet.

Testnet

Timestamp The shapella hard fork caused the network to no longer accept contract deployments because of a bug in Nethermind related to EIP-3860 and EIP-170 We fixed the network on May 26, 2023 by updating all Nethermind nodes It didn’t require a hard fork, as it’s the majority client on Chiado and technically didn’t do anything “wrong”, i.e. didn’t produce blocks that are invalid according to our spec

Hive

Tests for withdrawals Testing that the balance is applied correctly to the address. Sending transactions and checking that they are performing ok. Checking the storage after withdrawals are applied.

Testing sync Created blocks and transactions and connected other clients to test if they can sync.

Tested hard forks Next step is to add Erigon to the tests

Hive: Good progress pre and post-shanghai. Implement tests for post-shanghai scenarios. Syncing status: Producing blocks and sending transactions. Verified that withdrawals work like expected. Not getting the expected results. But the root is built correctly and the withdrawals are indeed being executed. Later (timeline: 2-3 weeks) Block reorgs and syncing issues. Edge cases: Integrate Erigon. Making sure that everything integrated with Nethermind also works with Erigon.

Can we try for May 24, 2023? Consensus chain variables. We’ll keep the same ones as Ethereum mainnet. How many withdrawal blocks should we accept?. On Ethereum it’s 16. Worst case it’s around 1.3 million gas per block. This would iterate over all partial withdrawals in ~8 hours, which is very fast. We could do 8 withdrawals per block. In any case we’ll add 550k gas per block. We have to define a list of KPI we want to reach on Chiado to consider it a success.

Research

Shutterized Beacon Chain No updates.

Withdrawals: Right now it’s fairly complicated to track information regarding withdrawals. We might need to change the signature of the withdrawal function. Should not be too complicated for Nethermind and Erigon. The contract would also require an update to track these changes

Tests

Hive:Added the integration with the withdrawal contract. Adding the way to test the balance of the contract and the amount on the accounts that have done withdrawals. Should be done by end of this week No ETA for the rest yet.

Confirming EIPs

• EIP-3651: Warm COINBASE

• EIP-3855: PUSH0 instruction

• EIP-3860: Limit and meter initcode

• EIP-170 is added as well because it was still missing https://eips.ethereum.org/EIPS/eip-170

• Regarding max code size

• EIP-6049: Deprecate SELFDESTRUCT

• EIP-4895: Beacon chain push withdrawals as operations** Gnosis modified. These need to be added to our specs repo https://github.com/gnosischain/specs/issues/5

• Nethermind: Started work on the shutter chain. Nothing specific to show yet. Running 50% Erigon nodes

• Erigon: No updates

• Geth: I got fullsync to kickstart after the database reconstruction: code was missing. I fixed this and now I am debugging the "system call" at the end of the block, where the block reward is distributed. Once this is fixed, and since it's the last thing that gets executed in the block, fullsync should work.

CL​

• Prysm: No updates.
• Nimbus: No updates.

Chain Infra

Gateway : Nothing specific. Igor is participating in a hackathon today

Devnet

No updates from Nethermind, Erigon or Gateway. Nethermind, ran a tool that generates bad blocks to test if the network handles them well. Everything is working well. Tests on Gnosis’ side; we haven’t tested a lot on our side yet. Defined a todo list of what we are going to test this week. https://github.com/gnosischain/consensus-deployment-ansible/issues/67

Research

Shutterized Beacon Chain Being implemented as a Nethermind plugin

Tests

Hive Last week’s issue was solved. Related to geth being hardcoded. Trying to make this more universal. It was recalculating a hash instead of just taking one received by the API. Ensure that we reach the TTD. Generating some post-shanghai blocks. During each step, we check if the chain is working correctly. Should have some withdrawal tests for end of next week.Focused on integrating the withdrawal contract this week
