Non-Staked nodes are in Neighborhood 0x00000000000...

[ldeffenb]

The latest Redistribution Contract in the Sepolia Testnet causes non-staked nodes to believe they are participating in neighborhood 0. This is due to the isParticipatingInUpcomingRound method using lastUpdatedBlockNumberOfAddress and overlayOfAddress from the Staking contract, both of which return 0 for non-staked nodes.

Consider the following contract query captures for my sepolia testnet node address 0x0e8a050ae87932b00a1acb01718654ac9fbb4c1e and overlay 0xa006d6ef64db7cb9a43681c69f06044851cc8b4a15f82da6d9194184b2347b53 with no stake in the current staking contracts.

{
  "overlay": "a006d6ef64db7cb9a43681c69f06044851cc8b4a15f82da6d9194184b2347b53",

}

From the Redistribution contract:

From the Staking contract:

This cause all non-staked nodes to calculate a hash and I have no idea what happens if they actually commit, reveal, and possibly try to claim a win in the round where their actual neighborhood wasn't actually selected.

Here's a sample commit transaction that failed because the node was not staked. https://sepolia.etherscan.io/tx/0xb68b97044cbe7d892bb784479bac14f86059a9d8d8ecc4d427732361b28c8f65 I suspect all of these failed transactions are caused by this same bug.

Here are the relevant lines from the commit transaction that causes the inappropriately generated hash to finally fail for non-staked nodes. A similar check is needed in isParticipatingInUpcomingRound instead of just running with the zeros. https://github.com/ethersphere/storage-incentives/blob/e70c3cd6e67325d666cec757d05a14bbb4fd05c3/src/Redistribution.sol#L283 https://github.com/ethersphere/storage-incentives/blob/e70c3cd6e67325d666cec757d05a14bbb4fd05c3/src/Redistribution.sol#L300-L302 But isParticipatingInUpcomingRound should simply return false instead of an error, IMHO.

yes, you are right, we should be including this kind of check in "isParticipatingInUpcomingRound". Adding this to release, thank you
