Block builders today have full control of the content in their blocks and have the ability to remove and/or insert transactions at any position. You can find some more details on how searchers and builders interact, and a some criteria to look for in a block builder, in our [Documentation](https://docs.flashbots.net/flashbots-auction/overview) and in [Searching Post-Merge](https://collective.flashbots.net/t/searching-post-merge/891).

We are working on reducing these trust assumptions, [since March we’ve been running](https://etherscan.io/address/0xc83dad6e38bf7f2d79f2a51dd3c4be3f530965d6) a [block builder inside an SGX enclave](https://writings.flashbots.net/block-building-inside-sgx), bringing us one step closer toward transaction confidentiality and decentralization of the block-building role.

Moving forward, with [SUAVE](https://collective.flashbots.net/tag/suave), we seek to substitute these trust guarantees further with robust cryptographic and cryptoeconomic assurances for comprehensive programmable privacy.
