attributes "resistance" does not working

[luoxingzlx]

I set a block's "resistance" value to 6000, but it can't resist TNT explosion. Then I tried the values of lava and iron blocks, but it didn't achieve the same effect as them.

This is my code.

    {
    "type": "block:simple",
    "entries": [
        {
            "id": "kuronekosgift:hairy_ball_block",
            "hardness": 50,
            "resistance:": 6000,
            "soundType": "metal",
            "light": 0,
            "flammability": 0,
            "fireSpreadSpeed": 0,
            "isFireSource": false,
            "isWood": false,
            "isOpaqueCube": true,
            "renderLayer": "solid",
            "harvestTool": "pickaxe",
            "harvestLevel": 3,
            "pathNodeType": "blocked",
            "creativeTab": "kuronekosgift_tab"
        }
      ]
    },
