In Ethereum with [PBS](https://ethresear.ch/t/proposer-block-builder-separation-friendly-fee-market-designs/9725), the block builders are the ones fixing the ordering of transactions. They try to maximize MEV in orders to gain advantage over other builders. And in a rollup world the sequencer is the one responsible for ordering and can therefore extract all MEV.(Epecially after decentralized sequemcers are introduced) > But what if all transactions are encrypted/hidden until it gets added or the ordering is fixed? - A user proposes a encrypted transaction with fees visible. - The sequencer builds a block, bundling the transactions with highest fees and adds it to the chain. without executing any transactions. Now the ordering of transaction is fixed and no one can change it. - After a specified amount of time the transaction data is revealed and executed. The execution can **succeed** or it can **fail**. ## Encrypted sequencing unlocks New Usecases when should be the transactions get revealed? If this parameter is configurable buy the user, for example set to 1 block, or 1 day. A dex will probably use few blocks to prevent frontrunning or sandwich attacks. New applications like Sealed bid auction are now easy to implement. By configuring the transaction to get revealed after the auction ends. ### Possible problems - **One can spam with invalid transactions:** If the gas fees for the transactions is not returned to user(even in-case of reverts), the spammer will lose money and needs to waste gas to censor the chain, similar to eth. - ....

Trustless Sealed Bid Auctions

Auctions are ubiquitous in crypto. From Maker collateral auctions, to Flashbots’ sealed-bid blockspace auctions and NFT auctions on OpenSea, auctions are suitable for a wide array of situations where price discovery, liquidity, or allocation of scarce resources is needed, both on and off-chain –a16zcrypto

Project GameNet

The internet has transformed the way we communicate, allowing us to connect with people from all over the world in real time. With the help of RSA, we can even communicate privately, enabling us to engage in activities that were once impossible.Like playing chess with anyone in the world However, for some applications, participants need to maintain private data and perform computations on it(for example maintaining bank balances, playing poker, sealed bid auctions, etc). Unfortunately, trusting anyone on the internet can be challenging, this led to the rise of trusted Centralized entities, such as governments or corporations with brand value, which everybody has to trust with their data.
