Chia Major Update Chia Releases 1.1.5 Update Chia coins with negative values ​​are added to transactions

According to official news, Chia released the 1.1.5 update version, which solved the problem of negative value transactions on the chain affecting slow node synchronization.

Officials said that there was no check for negative values ​​in the uint64 constructor. As a result, Chia coins with negative values ​​were added to the transaction memory pool.

These blocks passed validation, but since negative values ​​are not serialized in uint64, they were not added to the blockchain.

The farmers who create these blocks will produce a block that does not enter the main chain (forked chain).

As a result, Chia’s main chain began to slowly slow down from block height 255518 at around 6:35PM PDT.

This fix adds a check in the transaction mempool and block validation, and does not disconnect other nodes that send these invalid blocks (any 1.1.4 or earlier nodes), making the update not mandatory.

However, it is officially recommended to update. Users who do not update may see their blocks rejected by other nodes.

Chiafarm Fan Q&A Session

After yesterday’s article was published, some friends left messages in the background asking whether the old plots will be invalid after the new mining pool agreement goes online on the 17th. It is still unclear whether the pictures will be re-edited.

Let me start with the conclusion: old fields will not become invalid.

The mining pool protocol was launched this time, which upgraded the farms, but it mainly clarified the mechanism for farms to join the mining pool, rather than adjusting the mining algorithm, such as limiting multi-mining behavior, making the fee rate more transparent, and no longer requiring private keys, etc. (These are also the areas where mining pools are criticized now, some cannot do it, and some do not want to do it. But after the agreement is in place, future mining pools must strictly follow the agreement. So for mining, there is no impact, and the previous farms and solo mining can still be solo.

It is worth noting that: Jiutian can only join the mining pool in a "less safe" way, while Xintian can join the mining pool according to the mining pool agreement and can switch freely between legal mining pools.
