Whitechain

All the data that is used to construct the system state is published on chain in the form of cheap blobsThe data that a rollup publishes to its L1/data availability (DA) layer. They consist of the L2 transactions that are rolled up, along with some metadata. Blobs are introduced as a new transaction type within Ethereum with EIP-4844, and has rollup scaling specifically in mind. Blobs persist on Ethereum’s Beacon Chain ephemerally. or calldata. This ensures that it will be available for enough time.

The operatorAn operator is the entity charged with managing a rollup and progressing its state. A rollup operator can be a centralized sequencer, proposer, prover, challenger, pauser of admin that is able to perform upgrades. is the only entity that can propose blocksAn ordered list of transactions and chain-related metadata that gets bundled together and published to the L1/DA layer. Nodes execute the transactions contained within blocks to change the rollup chain’s state. Protocol rules dictate what constitutes a valid block, and invalid blocks are skipped over.. A live and trustworthy operator is vital to the health of the system.

Because the state of the system is based on transactions submitted on the underlying host chain and anyone can submit their transactions there it allows the users to circumvent censorship by interacting with the smart contract on the host chain directly.

The user initiates the withdrawal by submitting a regular transaction on this chain. When a state rootA cryptographic hash succinctly representing a state using a Merkle tree. containing such transaction is settled, the funds become available for withdrawal on L1Layer 1 (L1) is a blockchain that is self-reliant on its validator set for its security and consensus properties.

Withdrawal inclusion can be proven before state root settlementThe mechanism with which the execution of rollup blocks and the resultant state is verified and possible disputes are resolved. In the context of rollups or other modular blockchains, it often refers to the proof system used--validity (ZK) or fraud proofs, or a combination thereof. Sometimes it will refer to this mechanism along with where the mechanism's outputs are ultimately published and verified, as in Ethereum being a settlement layer by verifying the proofs and allowing for withdrawals., but a 7d period has to pass before it becomes actionable. The respected game type carries no on-chain challenge process, so settlement waits only for the delays above. Finally the user submits an L1 transaction to claim the funds. This transaction requires a merkle proof.

This category includes solutions like rollups as well as state channels and plasma. Other solutions are able to scale further, but with the introduction of additional trust assumptions, which are therefore not trust minimized. Sometimes the term Layer 2 is used to refer to include these solutions too, like validiums and optimiums, but to distinguish between trust minimized and non trust minimized solutions they are often referred to as "light" L2s, opposed to "strong" L2s like rollups.->L1Layer 1 (L1) is a blockchain that is self-reliant on its validator set for its security and consensus properties.

The system is then obliged to service this request or halt all messages, including forced withdrawals from L1 and regular messages initiated on L2. Once the force operation is submitted and if the request is serviced, the operation follows the flow of a regular message.

OP stack chains are pursuing the EVM EquivalenceA perfect degree of compatibility; where one system or concept is indistinguishable from another in the domain being compared. In the context of rollups, it generally refers to the proximity to the EVM and to Ethereum architecture. model.

Assets move between Ethereum, Tron and Whitechain mostly through the Portal, a bridgeA message-passing protocol between two blockchains. At its most basic, a token bridge consists of a smart contract which can escrow funds on one side of the bridge, and instruct the release or minting of corresponding assets on the other side, but bridges could also support arbitrary messages. How these instructions are validated is a critical factor in assessing the trust assumptions of a bridge. operated by Whitechain in which a single relayer key authorizes every release and an operatorAn operator is the entity charged with managing a rollup and progressing its state.
