$DNA Utility

PayForQuery Transactions

To publish data on DNA Layer developers can submit PayForQuery transactions. A PayForQuery transaction consists of the evolving request, the evolving size, the identity of the sender of the data to be made available for, the namespace, and a signature. Each PayForQuery transaction is split into two parts: the evolution which includes the data to be made available along with the namespace, and the executable payment transaction which includes a commitment to the data.

Both the evolution and executable payment transactions are put into the block within the appropriate namespace. The block data is extended using erasure coding and then Merkelized into a data root commitment included in the block header.

Fee Market Overview

DNA Layer uses a standard gas-price prioritized mempool. This means that transactions with higher fees will be prioritized by validators. Fees are comprised of a flat fee per transaction and then a variable fee based on the size of each evolve in the transaction.

Network Parameters

$DNA holders - not just stakers - can propose and vote on governance proposals to change a subset of network parameters. DNA Layer will publicly list both the changeable and non-changeable parameters and their values of the system to vote on.

queryStream flow of communication. queryStream is DNA’s method to stream verified transaction data from a query inference request to DNA Layer's Settle- ment Layer for registry on the blockchain. With DNA Layer's interoperable structure, users can elect to stream to another blockchain network such as Ethereum at their preference. The module on DNA Layer flows through attestation and orchestrators to the queryStream P2P Network, and then into a dedicated Relayer that streams the query result to DNA Layer's Settlement Layer or to Ethereum for settlement. The queryStream contract is then formalized on DNA Layer, executing the model inference end-to-end.

Community Pool

Starting at Genesis, DNA Layer's community pool receives 2% of all $DNA Layer block rewards. $DNA stakers may vote to fund ecosystem initiatives.

queryStream

queryStream interfaces with DNA Layer's crypto-economic framework backed by its Proof-of-Stake consensus protocol. By utilizing DNA Layer's Consensus Layer, computations for AI model inference are transparent and subject to scrutiny by the network of validators and their delegators through an efficient attestation mechanism.

In scenarios where dishonest activities are suspected, such as data withholding by validators, the system is designed to recognize any malfeasance if 2/3 of DNA Layer validators are implicated, prompting actions such as slashing to maintain network integrity. This modular verification layer provides strong crypto-economic security

Block production for a PayForQuery transaction. When initiated, a names- pace and query details are established, and the transaction is signed. It is then passed through the system as it is shared with the Consensus Layer for verification and DNA Core where it is prepped for settlement.

assurances, raising the standard for trust in decentralized AI model evolution.

queryStream enables developers to tap into DNA Layer's scalable name space-specific storage, which may start at a few hundred kb per inference query on the Mainnet Beta, with potential increases manageable through on-chain governance. The actual storage provision is based on the complexity and size of the query and underlying model and supports the potential for tens of thousands of model parameters to be processed per second due to the efficient use of erasure coding and Merkle tree data structures.

The communication between DNA Layer's verification layer and its settlement layer (or Ethereum’s settlement layer given that DNA Layer is interoperable) is facilitated by a peer-to-peer (P2P) network which includes a queryStream Relayer. The Relayer streams the query data from the verification layer to the settlement layer (or to the Ethereum network), where dedicated smart contracts formally encode and execute the query directives received from DNA Layer.

Every PayForQuery transaction submitted to DNA Layer is validated with a Byzantine Fault Tolerant (BFT) signature mechanism. Any AI model data included in DNA Layer can be independently verified on Ethereum using queryStream, with validation results backed by cryptographic proofs. On settlement, the AI model inference proofs and PayForQuery transaction data are published to DNA Layer.

Tokenomics relationship on DNA Layer. Miners are required to stake a portion of $DNA for a vested interest in the honest and efficient processing of AI queries on behalf of the dApp user.

For ZK rollups employing queryStream, data inclusion must be verified before considering any proof as valid. This can be done by incorporating the inclusion proof within the ZK proof itself for submission to DNA Layer's settlement layer, or another blockchain network like Ethereum.

Token Fee Mechanism

We summarize these high-level insights into the tokenomics of the platform which describes the token-based relationship between participants in the DNA ecosystem. On DNA Layer, miners are required to stake a portion of $DNA tokens. This requirement serves as a safeguard, ensuring that miners have a vested interest in the honest and efficient processing of AI queries.

This aspect of our system draws parallels to the concept of oracles in blockchain, yet with a unique focus on AI model execution.

DNA Layer's token fee mechanism introduces a flexible economic model: the more tokens committed, the larger the pool of miners, hence enhancing security with more proofs attached in the queryStream. Conversely, spending fewer tokens results in a smaller miner pool, indicating a trade-off between cost and security.
