In testing pursuant to [https://forum.cosmos.network/t/amulet-security-advisory-for-cometbft-asa-2023-002](https://forum.cosmos.network/t/amulet-security-advisory-for-cometbft-asa-2023-002) it’s been clearly found that the current 200kb block size poses a class of risks.

These risks have been explained in the validators private discord, and any validator can reach out to me at [https://twitter.com/gadikian](https://twitter.com/gadikian) to have the issues explained in detail, if need be. Validators needing more information will be added to the Validators Working Group On Spam suggested by Amulet in [https://forum.cosmos.network/t/amulet-security-advisory-for-cometbft-asa-2023-002](https://forum.cosmos.network/t/amulet-security-advisory-for-cometbft-asa-2023-002).

Current baseapp BlockParams: 200 kilobytes

```json
{
  "subspace": "baseapp",
  "key": "BlockParams",
  "value": "{\"max_bytes\":\"200000\"}"
}

```

Future baseapp BlockParams: 2 megabytes

```json
{
  "subspace": "baseapp",
  "key": "BlockParams",
  "value": "{\"max_bytes\":\"2000000\"}"
}

```
