How are transaction hashes structured in the new format?

[devendran-m]

How are transaction hashes structured in the new format and how can I identify it, for instance in the JSON RPC response of chain_get_block?

[devendran-m]

Transactions are grouped by keys/categories under .result.block_with_signatures.block.Version2.body.transactions path of the response.

• For example, all transactions are stored under a particular key/category. For instance, 0 is for Mint.
• Available categories include Mint (0), Auction, Wasm categories, etc.
• The categories can be found in the transaction_v1_category.rs file.
• The transactions are detailed, as shown in the example response below.

P.S. - Answer / Explanation based on the details shared by @rafal-ch in a Slack conversation.

Response format: body.transactions
Note: 0 is a key/category

{
    "transactions": {
        "0": [
            { "Deploy": "hash1" },
            { "Deploy": "hash2" }
        ]
    }
}
