Many developers' first impression of ZK is complex circuit DSL and the lengthy 'proof debugging'. SP1's route is different: using a general ISA (RISC-V) to accommodate programs, leaving proof performance issues to the underlying system team. What you care about is 'whether the function f is executed correctly', rather than 'how to translate f into gate circuits'. This represents a division of engineering labor: encapsulating the most difficult layer and returning 'proof' to those who write the business logic.

I. From Rust to Proof: Four-step Link

The official documentation breaks down the development process of SP1 into four straightforward steps: define function → compile to RISC-V ELF → generate keys → proof and verification. Each step has ready-to-use commands and examples, eliminating the need to read an entire book on algebraic geometry. For teams that prioritize 'hands-on experience before optimization', this 'entry barrier' is more important than any paper metrics.

II. Why Choose RISC-V

Mature Ecosystem: Complete compiler, debugger, and toolchain; Rust/C/C++ can all compile smoothly;

Semantic Stability: Avoid unforeseen overhead brought by 'specialized VMs';

Composable: Assemble multiple sub-programs into the same proof process, with controllable overhead during recursion.

Both the GitHub and documentation pages highlight the selling point of 'supporting any LLVM language' upfront, which is a necessary condition for 'bringing more people in'.

III. Performance is not a one-liner: consider workloads and system iterations

The open lecture notes from Stanford's course mention that 'the 2024 version of SP1 achieved a 27x speed advantage on some workloads'. This encompasses two layers of work:

Algorithm Layer: Selection and optimization of constraint systems, constant factors of commitment schemes, assembly methods of recursive building blocks;

System Layer: GPU/multi-core parallelism, pipelining, memory layout, aggregation proof strategies.

Only by continuously refining these two layers can we qualify to 'bring ZK back from a specialized project to a regular project'.

IV. SP1's 'Usability Moment' comes from concrete implementation

In July, Succinct and World Foundation jointly announced 'conducting validity proof experiments on the World Chain', aiming to compress the correctness of each transaction into a proof, providing a 'switch to validity' channel for large-scale L2. The article also mentions a key point: relying on a decentralized proof network, even large Rollups can obtain proof services at predictable costs and delays. This 'OP Succinct' idea indicates that SP1 is not only focused on single-machine performance but is also creating an 'engineering closed loop'.

V. From Tool Stack to Product Stack: Three entry points: Rollups / Coprocessors / Bridges

The official website categorizes developer entry points into three types:

Rollups: Generate validity proofs for your state transition functions, bridging to L1/other settlement layers;

Coprocessors: Use ZK to verify the results of off-chain heavy tasks on-chain, commonly used in risk control, batch settlement, machine learning inference, etc.;

Bridges: Use lightweight client proofs to replace 'optimistic waiting' or multi-signature trust.

The common point behind these three types of entry is: packaging credibility as proof objects, rather than requiring users to read logs and source code for self-verification.

VI. Developer Predictability: Interface, Pricing, SLA

Once proof is outsourced to the network, developers care about three things:

Interface Stability: Version rhythm of SDK and API, backward compatibility strategies;

Price Curve: The marginal change of document cost with respect to input scale and safety parameters; SLA: Delay quantiles, failure/retry strategies, observability.

Mainnet release commits 'scalable, verifiable computation', allowing you to track over the long term based on this commitment: call counts, average proof time, timeout rates, distribution of aggregate batch sizes, etc. These 'hard metrics' speak more convincingly to developers than slogans.

VII. Boundaries: ZK is not a silver bullet

Wrong logic can still be 'correctly executed': what is proven is 'executed according to your program', not 'your program is correct';

General zkVM ≠ Specialized Circuits: In extreme throughput scenarios, handwritten circuits can still prevail;

Call Serialization Risks: If the entire business is placed into a single proof, delays and failure retries will explode concentrically.

SP1's choice of 'generality and usability' means it must coexist with specialized circuits in the long term—bringing in 80% of the demand first, allowing the remaining 20% of extreme players to continue competing in specialized tracks.
