Grin will usher in its first hard fork in July. Are you aware of algorithm adjustments, protocol upgrades, and deprecated versions?

Grin’s first hard fork (mid-July)

Block height and date

Summarize

Grin stated from the beginning that there would be four forks in the first two years of launch. Each time 6024726=262,080 blocks (last 6 months interval). The block heights set in the code are 262,080, 524,160, 786,240 and 1,048,320. The first network upgrade is expected in mid-July, grin
node, grin-wallet, and grin-miner will be upgraded to 2.0.0 or higher, and the first batch of versions is expected to be released in June.

This article will outline the major changes, timing, and communication matters in the new upgrade to ensure a smooth upgrade and give ecosystem participants sufficient time to prepare.

Key points:

Grin v2.2.0 is a major network upgrade. Users only need to update the binary file for subsequent transactions. Stored Grin is not affected, beware of fake news encouraging you to transfer tokens.

Big changes

node:

·
Algorithm adjustments. Grin will adjust the PoW algorithm every 6 months to prevent ASICs from building proprietary hardware to control mining. Therefore, the previous Cuckaroo29 was updated to Cuckarood29, and the mining software must upgrade the solver program.

· Cuckarood29 definition: Hard fork in mid-July, Cuckaroo29 was upgraded to Cuckarood29.

· Cuckarood resource library: 

· Corresponding Grin HF PoW performance: 

· Grin miner improvement request: 

wallet:

· Changes in bulletproof rewind plan: 
wallet/issues/105. The rewind program adds flexibility to the wallet and the ability to bulletproof hidden information. In order to conduct transactions on the post-fork chain, the wallet is forced to upgrade to version v2.2.0 or higher.

· API upgrade to V2: V1 REST API is upgraded to V2 JSON-RPC API. The upgrade file is as follows:

· ForeignAPI

· OwnerAPI

· Slate V0 (created by Grin 1.0.2 or below) will be deprecated and will not be compatible with the new version of Grin.

Therefore, mining pools, mining machines, exchanges, and various participants in the grin protocol must upgrade to v2.2.0 or higher. Nodes that have not been upgraded will not be able to package new blocks after the fork, and wallets that have not been upgraded will not be able to create and publish transactions after the fork.

Operational requirements

schedule

To ensure a smooth upgrade for everyone, Grin developers have set the following schedule:

Note: The actual date may vary slightly depending on circumstances, but the hard fork block height remains unchanged.

Before the hard fork, the Grin team and community will communicate through the following media:
