DON-Blockchain-Skalierung
Context
This figure appears in the Introduction during the discussion of scaling as one of the seven key design goals. It contrasts a conventional oracle architecture with a DON-enhanced architecture to demonstrate how DONs shift the main locus of transaction processing off-chain, reducing latency and fees while increasing throughput. The figure accompanies the whitepaper's assertion that DONs may effectively function as layer-2 technologies.
What This Figure Shows
Figure A shows a conventional oracle architecture where transactions and oracle reports are sent directly to the blockchain, making the blockchain (highlighted in yellow) the primary site of transaction processing. Figure B shows how a DON executable processes transactions together with data from external systems, forwarding only results—such as bundled transactions or state changes—to the blockchain. In this model, the DON (highlighted in yellow) becomes the main locus for transaction processing, dramatically reducing the volume and frequency of on-chain operations. This shift mirrors the approach taken by layer-2 systems such as rollups.
Significance
This figure visually demonstrates the core scaling argument for DONs: by moving the computational burden off-chain while retaining the blockchain as a settlement and security layer, DONs can dramatically improve throughput and reduce costs. It establishes the DON-as-layer-2 concept that is later formalized through the Transaction Execution Framework.
