Synapseia is a peer-to-peer network of independent operator nodes that collaboratively run scientific research workflows. Each node is an autonomous AI agent — running on someone's laptop, workstation, or datacenter GPU — that participates in one or more research training tracks (ALS, oncology, cardiology, neurology, rare disease, plus operator-proposed tracks). The network does five things on a continuous cycle: - Searches for the analysis configuration that wins on quality and latency. - Opens research rounds against curated corpora (PubMed, ClinicalTrials.gov, preprints). - Analyses papers in parallel — every node works a different paper. - Peer-reviews each other's outputs with signed scores. - Promotes high-scoring analyses to *discoveries* and writes them into a shared knowledge graph distributed across the peer mesh. There is no central server holding the data path. A coordinator (a small NestJS service) signs grants, opens rounds, and arbitrates the economy — but it is NOT in the critical hot path for queries, snapshots, or peer-to-peer messaging. --- ## Core principles - **P2P first.** libp2p gossipsub for fan-out, direct streams for shard data, signed envelopes for every authority claim. - **Coord-light.** The coordinator stays out of the data path so adding operators scales the network horizontally instead of bottlenecking a single node. - **Verifiable.** Every analysis, every review score, every shard ownership grant is signed (Ed25519) and replayable. - **Open.** Node agent, desktop UI, protocol specs, and Solana contracts are public. Any operator can audit, extend, or fork. The coordinator service stays closed source — its role is signing grants and opening rounds, not holding user data. --- ## Research tracks A research track is a self-contained scientific domain. Each one carries: - Its own corpus slice (e.g. ALS sub-corpus from PubMed + ClinicalTrials.gov). - Its own configuration leaderboard (the winning prompt template / temperature / chunk size for that domain). - Its own active research rounds. - Its own peer-review pool. - Its own discovery feed in the shared knowledge graph. Active tracks today: `als`, `cardiology`, `oncology`, `neurology`, `rare-disease`, plus operator-proposed tracks ratified by stake. > [!NOTE] > Tracks are independent. A node can opt into one track or all of them — there is no global ordering or central scheduler. Multiple rounds (one per track) run side-by-side at any moment. --- ## Work types Within every track, the coordinator opens eight different kinds of work order — four of them training variants tuned for different hardware tiers and update cadences. A node picks which ones it accepts based on hardware capability — a laptop can chew on research analysis, CPU training, and CPU inference; a workstation with a GPU can additionally run GPU training rounds, DiLoCo federated training, LoRA adapter training, and GPU inference. Pool sizes below are coord defaults and can be tuned by operator vote. ### Research analysis The flagship work type. `33,900 SYN` daily pool, one round per day. Nodes read papers, score methodology, propose hypotheses, and link findings into the shared knowledge graph. Top-3 analyses split `60 / 25 / 15`; an extra 10 % goes to peer reviewers. Hardware: any node. ### GPU training (rounds) Regular GPU fine-tuning rounds: `4,000 SYN` per round, `4 rounds / day` (6h each), `16,000 SYN` daily. Each round splits `2,400 / 1,000 / 600` across the top-3 (60 / 25 / 15). Standalone single-node GPU training jobs queued via `WorkOrderType.TRAINING` with the `gpu-medical` domain. Hardware: GPU required. ### DiLoCo (federated GPU) `3,500 SYN` per round, irregular cadence — the coordinator triggers DiLoCo (Distributed Low-Communication) rounds on demand when a model checkpoint needs collaborative updates. Operator GPUs sync gradients infrequently enough that consumer uplinks suffice — no datacenter fabric required. Top-3 split `2,100 / 875 / 525` per round. Hardware: GPU required, multi-node coordination. ### CPU training `3,000 SYN` per round, `4 rounds / day` (6h each), `12,000 SYN` daily. Fine-tunes biomedical micro-transformers on the corpus for tasks where a small specialised model beats the giant generalist (entity extraction, BIO tagging, citation parsing). Any node with Python + PyTorch can run a round. Top-3 split `1,800 / 750 / 450`. ### LoRA training Per-WO reward, `5,000 SYN` on validation pass — not a pool. Mission admins queue adapter requests; the coordinator mints a `LORA_TRAINING` work order and the trainer node uploads the resulting adapter for automated verification. Two subtypes: `LORA_CLASSIFICATION` (PubMedBERT encoder, for relation extraction and paper classification) and `LORA_GENERATION` (BioGPT-Large decoder, for hypothesis generation and summarisation). Reward only fires if `LoraVerificationService` confirms the adapter beats the prior verified baseline on held-out validation metrics — failed adapters earn nothing, but there is no monetary penalty (stake untouched). Each new VERIFIED adapter SUPERSEDES the previous one for that mission + base model. Hardware: GPU required, tier `T2+` stake gate. ### CPU inference Reactive jobs the research analysis spins up mid-round. First-come-first-served — fast nodes win. Per-task payouts: `2 SYN` tokenize, `10 SYN` embed, `15 SYN` classify. Daily volume floats with research demand; expect dozens of tasks per day per active node. Hardware: any modern laptop. ### GPU inference Same FCFS reactive pattern, but for jobs the CPU variant cannot serve in time: large-model embeddings, long-context summarisation, generation. Per-task payouts by complexity: `30 / 40 / 50 SYN`. Hardware: GPU required. ### Molecular docking Drug-discovery cross-verification. Two operator nodes independently score the same ligand-target pair. If their scores agree (within tolerance), both get paid: `1,000 SYN` per agreed pair, split `600 / 400` between the two agreeing nodes. Disagreements escalate to a third tie-breaker. Hardware: GPU recommended; CPU works but slower. > [!NOTE] > Peer review is not a separate work type — it's baked into the research-analysis economy via the 10 % reviewer pool. Reviewer payouts scale with the *quality* of the review, not just the count, so rubber-stamping earns nothing. --- ## Configuration search (Stage 1) Before a research round opens, the network searches for the analysis configuration that produces the highest-quality outputs at acceptable latency. Every node runs its own experiment locally — different prompt templates, temperatures, chunk sizes, analysis depths — and reports back to a CRDT (conflict-free replicated data type) leaderboard. CRDT means no central server: every node eventually converges on the same ordering without a quorum round trip. > [!NOTE] > The leaderboard is per-track. The best ALS config is not automatically the best oncology config — domains have different evidence thresholds, terminology, and structural expectations. --- ## Research rounds (Stage 2) A round is a unit of work: a corpus slice + a winning config + a fan-out of work orders. The coordinator opens rounds; the swarm executes them. Work orders are broadcast on libp2p gossipsub (`WORK_ORDER_AVAILABLE`). Every node maintains a local push queue and drains it without polling — the legacy HTTP `GET /work-orders/available` endpoint stays as a 5-minute safety net only. --- ## Paper analysis (Stage 3) Each node runs the round's winning config against its assigned papers. Output is a structured analysis: methodology score, key findings, cross-references to existing knowledge graph nodes, and any hypotheses generated. Cross-references are computed against the local shard slice of the knowledge graph (no round-trip to coord). See [distributed knowledge graph](#distributed-knowledge-graph) below. --- ## Peer review (Stage 4) Every analysis lands in front of N other nodes for review. Reviewers score on rigour, novelty, evidence quality, and reproducibility — each score signed with the reviewer's Ed25519 identity and gossipped over libp2p. Reviews are CRDT-merged on the leaderboard so no central authority decides what is good; the swarm does. > [!WARNING] > Reviewing is not free. Lazy or sybil reviewers (e.g. rubber-stamping) lose presence points and tier multiplier over time. Quality of review is itself peer-scored. --- ## Discoveries (Stage 5) Analyses that average `≥ 8/10` across peer reviews are promoted to discoveries. A discovery is a permanent entry in the shared knowledge graph with: - The structured analysis output. - The peer-review score breakdown. - Cross-links to every related knowledge-graph node touched during analysis. - An on-chain commit (Solana) so the timestamp + author cannot be rewritten. --- ## Distributed knowledge graph The knowledge graph is the network's shared brain. Every embedding, every cross-reference, every discovery lives here. The coordinator does NOT host it. The peer mesh does. - **32 shards × 3 replicas.** Each embedding is deterministically hashed into one of 32 shards, and each shard is hosted by 3 different operator nodes. - **~95 MB raw / shard at 1M corpus.** A peer hosting 3 shards needs ~285 MB raw + HNSW index — Tier 1-2 operators (laptops) can host without strain. - **HNSW (usearch) per shard.** Top-K semantic search returns in ~0.3 ms locally on the host node. No round-trip to coord on the read path. --- ## Shard routing The shard for a given embedding is computed deterministically: ``` shardId = sha256(embeddingId).readUInt32BE(0) % 32 ``` Both the coordinator (publisher / snapshot server) and every node (delta handler / snapshot client / HNSW searcher) compute the same shard for the same embedding — the helpers are byte-identical mirrors and a regression vector locks the expected output for 5 known IDs at counts 32 and 4 to catch any drift. Cold-boot peers pull shard snapshots from *other peers* first (chained sync), and only fall back to coord when no peer-to-peer source is available. Once a peer announces readiness on `KG_SHARD_SNAPSHOT_READY`, every subsequent cold boot inherits that source — coord uplink stays at zero in steady state. --- ## Envelope security Every cross-peer authority claim is double-signed: - **Row-level signature** — the coord signs the raw bytes `||` at grant time. Any node can verify this signature against the `kg_shard_authorizations` row. - **Envelope signature** — gossipsub messages are signed over canonical JSON of `{body, publishedAt}` with a freshness window of `−60s past / +5s future` so a stolen signature cannot be replayed. > [!NOTE] > Anti-spoof: `KG_SHARD_SNAPSHOT_READY` envelopes carry the announcer's full 32-byte pubkey. The verifier asserts `pubkeyHex.startsWith(peerId)` BEFORE the Ed25519 check, so a peer cannot claim shard ownership under a different identity. --- ## SYN token SYN is the network's native Solana SPL token. It is: - Earned by operators for every contribution (research, training, peer review, inference). - Staked to unlock higher tiers and compounding multipliers. - Locked into the staking pool to earn from the daily reward distribution. - Used to propose new training tracks (stake-gated governance). --- ## Staking and tiers Operators stake SYN to climb tiers. The tier multiplier scales every reward pool an operator participates in: - `T0 = 1.0×` — unstaked baseline. - `T1 = 1.2×` - `T2 = 1.5×` - `T3 = 2.0×` - `T4 = 2.5×` - `T5 = 3.0×` — top tier. Beyond the work multiplier, staked SYN earns a proportional share of the daily reward pool — even when the node is offline. --- ## Rewards Every contribution to the network earns SYN. Daily pools and per-task payouts come straight from `RewardsConfigService` on the coordinator — operators can tune them via on-chain vote, but the defaults are: - **Research analysis** — `33,900 SYN` daily pool, 1 round / day. Top-3 analyses split 60 / 25 / 15 (`20,340 / 8,475 / 5,085`); an additional 10 % of the pool routes to peer reviewers proportional to review quality. - **GPU training (rounds)** — `4,000 SYN` per round, 4 rounds / day (`16,000 SYN` daily). Each round splits `2,400 / 1,000 / 600` top-3. Standalone single-node GPU fine-tuning jobs. - **DiLoCo (federated GPU)** — `3,500 SYN` per round, irregular cadence triggered by checkpoint demand. Top-3 split `2,100 / 875 / 525`. Multi-node low-communication gradient sync. - **CPU training** — `3,000 SYN` per round, 4 rounds / day (`12,000 SYN` daily). Each round splits `1,800 / 750 / 450` top-3. Fine-tunes biomedical micro-transformers on the corpus. - **LoRA training** — `5,000 SYN` per work order, paid only on automated validation pass. Two subtypes: PubMedBERT (classification) and BioGPT-Large (generation). GPU required, T2+ stake gate. - **CPU inference** — `2 / 10 / 15 SYN` per task (tokenize / embed / classify). Reactive jobs the research analysis spins up; first-come-first-served. - **GPU inference** — `30 / 40 / 50 SYN` per task by complexity. Same FCFS pattern as CPU inference but for heavy generation, summarisation, and large-model embeddings. - **Molecular docking** — `1,000 SYN` per agreed ligand-target pair, split `600 / 400` between the two independently-scoring nodes. No daily pool — payment fires the moment two agents agree. > [!NOTE] > Tier multiplier (`T0 = 1.0×` through `T5 = 3.0×`) applies on top of every payout above. Stake more SYN, climb tiers, amplify earnings. > [!NOTE] > Presence points (legacy uptime metric) are a secondary signal — they break ties at the bottom of the leaderboard but do NOT meaningfully shape rewards. Quality of work and tier multiplier do the heavy lifting. --- ## Running a node The desktop app for macOS, Windows, and Linux ships at mainnet launch — one-click install, automatic updates, wallet baked in. Until then, the source repository on GitHub is the canonical reference. Hardware tiers map roughly to: - Tier 1 — laptop (CPU only). - Tier 2 — workstation with consumer GPU. - Tier 3 — single datacenter GPU (e.g. A100 partition). - Tier 4-5 — multi-GPU rigs. The agent loop is autonomous — once configured, the node participates in rounds, hosts knowledge-graph shards (if granted), and earns rewards without operator intervention. --- ## Security model - **Ed25519 identity per node.** Every signed envelope, every review, every shard ownership claim is attributable to a specific operator pubkey. - **Coord pubkey hardcoded** in every node binary. There is no env var to swap it — operators get the same trust anchor by virtue of running an official release. - **Replay windows are asymmetric** (−60s past / +5s future) so a stolen signature has at most a 5-second future-skew window to land. - **Sybil resistance via stake.** Tier 0 nodes can participate but earn at the baseline; meaningful influence requires staked SYN. --- ## Governance Network governance is stake-weighted: - Operators stake SYN to propose new training tracks. The proposal is ratified once a quorum of staked operators signals support. - Coordinator releases are signed; nodes verify the signature before accepting an upgrade. - Protocol changes that touch on-chain contracts go through a longer ratification window — the codebase is open, the contracts are auditable.
