A Whole Block purchased in the primary market reserves the entire block, \~ 36mm gas units (remark: gas limit can be dynamically adjusted by validators), for the buyer. Buyers may decide to **strip apart** and sell a mix of Inclusion Preconfirmations or Execution Guarantees. At such point, the Whole Block instrument now comprises a mix of other commitments whereupon subsequent secondary market sales of the Whole Block will be defined to be contingent upon including those other commitments.&#x20;

**Sequencing Rights** are also conferred to the Block Buyer making a whole block buyer a synthetic Block Builder as articulated in [The Design Process](https://docs.ethgas.com/overview/our-technology/the-design-process). Should a block buyer looking to retain key positions/guarantees in a block be unable to [Sequence a block accordingly](https://docs.ethgas.com/get-started/builders-and-sequencers), they may include their own Execution Guarantees or Inclusion Preconfirmations, and either:

* Not sequence the Block, following which ETHGas will be the fallback Builder,
* Sell the Block, or
* Delegate the Sequencing to a specific Builder

Market Details:

* Transaction Fees: \[ 5% ] on Primary sale, \[ 30 ]bps on secondary market trading TBC
