Overview The ChaosChain Gateway is an off-chain orchestration layer that handles:
Workflow execution (work submission, scoring, epoch closure)Transaction serialization (one nonce stream per signer)Evidence archival to ArweaveDKG computation (deterministic, server-side)
Key Principle : The Gateway is economically powerless. All authoritative decisions occur on-chain.
Gateway Design Invariants Invariant Meaning Contracts are Authority On-chain state is always truth; Gateway reconciles DKG is Pure Same evidence → same DAG → same weights (no randomness) TX Serialization One signer = one nonce stream (no races) Crash Resilient Workflows resume from last committed state Protocol Isolation Gateway bridges StudioProxy ↔ RewardsDistributor
When to Use the Gateway Use Case Direct SDK Gateway Simple transactions ✅ ✅ Multi-step workflows ❌ ✅ Crash recovery ❌ ✅ Evidence archival Manual Automatic DKG computation SDK-side Server-side
Recommendation : Use the Gateway for all production workflows.Quick Start Python
TypeScript / JavaScript
from chaoschain_sdk import GatewayClient # Connect to Gateway gateway = GatewayClient( "https://gateway.chaoscha.in" ) # Check health status = gateway.health_check() print ( f "Gateway: { status[ 'status' ] } " ) # Submit work result = gateway.submit_work( studio_address = "0xF795D41267DEf795f6f870d5d5be833Eb9703E86" , data_hash = "0x1234..." , thread_root = "0x5678..." , evidence_root = "0x9abc..." , signer_address = "0xMyWallet..." ) # Wait for completion final = gateway.wait_for_workflow(result.workflow_id, timeout = 300 ) print ( f "✅ Completed: { final.tx_hash } " )
import { ChaosChainSDK , NetworkConfig , AgentRole } from "@chaoschain/sdk" ; const required = [ "PRIVATE_KEY" , "RPC_URL" , "GATEWAY_URL" ]; for ( const key of required ) { if ( ! process . env [ key ]) throw new Error ( `Missing ${ key } ` ); } const sdk = new ChaosChainSDK ({ agentName: "WorkerAgent" , agentDomain: "worker.example.com" , agentRole: AgentRole . WORKER , network: NetworkConfig . BASE_SEPOLIA , privateKey: process . env . PRIVATE_KEY ! , rpcUrl: process . env . RPC_URL ! , gatewayConfig: { gatewayUrl: process . env . GATEWAY_URL ! }, }); const health = await sdk . gateway ! . healthCheck (); console . log ( `Gateway: ${ health . status } ` );
Gateway required for orchestration : If gatewayConfig is not provided, sdk.gateway is unavailable and Gateway workflows will throw a configuration error.
The SDK emits warn-once messages when Gateway is not configured on non-local networks and when StudioClient is used in production.
Workflow Types WorkSubmission (6 Steps) The Gateway orchestrates the complete work submission lifecycle:
UPLOAD_EVIDENCE → AWAIT_ARWEAVE_CONFIRM → SUBMIT_WORK_ONCHAIN → AWAIT_TX_CONFIRM → REGISTER_WORK → AWAIT_REGISTER_CONFIRM → COMPLETED
Step Action UPLOAD_EVIDENCEUpload evidence package to Arweave AWAIT_ARWEAVE_CONFIRMWait for Arweave tx confirmation SUBMIT_WORK_ONCHAINSubmit to StudioProxy.submitWork() AWAIT_TX_CONFIRMWait for blockchain confirmation REGISTER_WORKRegister with RewardsDistributor.registerWork() AWAIT_REGISTER_CONFIRMWait for registration confirmation
Why REGISTER_WORK? StudioProxy and RewardsDistributor are isolated by design. The Gateway bridges this gap so closeEpoch() can succeed.
Python
TypeScript / JavaScript
result = gateway.submit_work( studio_address = "0x..." , data_hash = "0x..." , thread_root = "0x..." , evidence_root = "0x..." , signer_address = "0x..." , # Optional multi-agent participants = [ "0xAlice..." , "0xBob..." ], contribution_weights = [ 6000 , 4000 ], # basis points evidence_cid = "Qm..." )
const result = await gateway . submitWork ( "0xStudio..." , 0 , "0xAgent..." , "0xDataHash..." , "0xThreadRoot..." , "0xEvidenceRoot..." , Buffer . from ( "evidence" ), "0xSigner..." );
ScoreSubmission (6 Steps) SUBMIT_SCORE → AWAIT_SCORE_CONFIRM → REGISTER_VALIDATOR → AWAIT_REGISTER_VALIDATOR_CONFIRM → COMPLETED
Supports two modes:
Direct Mode (Default)
Commit-Reveal Mode
Python
TypeScript / JavaScript
from chaoschain_sdk.gateway_client import ScoreSubmissionMode result = gateway.submit_score( studio_address = "0x..." , data_hash = "0x..." , worker_address = "0xWorker..." , scores = [ 8500 , 9000 , 8800 , 9200 , 8700 ], signer_address = "0xVerifier..." , mode = ScoreSubmissionMode. DIRECT # Default )
import { ScoreSubmissionMode } from "@chaoschain/sdk" ; const result = await gateway . submitScore ( "0xStudio..." , 0 , "0xVerifier..." , "0xDataHash..." , [ 8500 , 9000 , 8800 , 9200 , 8700 ], "0xSigner..." , { workerAddress: "0xWorker..." , mode: ScoreSubmissionMode . DIRECT } );
Direct mode calls StudioProxy.submitScoreVectorForWorker() directly. Python
TypeScript / JavaScript
result = gateway.submit_score( studio_address = "0x..." , data_hash = "0x..." , scores = [ 8500 , 9000 , 8800 , 9200 , 8700 ], score_hash = "0x..." , score_salt = "0x..." , signer_address = "0xVerifier..." , mode = ScoreSubmissionMode. COMMIT_REVEAL )
import { ScoreSubmissionMode } from "@chaoschain/sdk" ; const result = await gateway . submitScore ( "0xStudio..." , 0 , "0xVerifier..." , "0xDataHash..." , [ 8500 , 9000 , 8800 , 9200 , 8700 ], "0xSigner..." , { mode: ScoreSubmissionMode . COMMIT_REVEAL , salt: "0x..." } );
Commit-reveal prevents last-mover bias (two-phase: commit hash, then reveal). CloseEpoch (4 Steps) CHECK_PRECONDITIONS → SUBMIT_CLOSE_EPOCH → AWAIT_TX_CONFIRM → COMPLETED
Python
TypeScript / JavaScript
result = gateway.close_epoch( studio_address = "0x..." , epoch = 0 , signer_address = "0xOwner..." # Must be Studio owner ) final = gateway.wait_for_workflow(result.workflow_id) print ( f "✅ Epoch closed, rewards distributed" )
const result = await gateway . closeEpoch ( "0xStudio..." , 0 , "0xOwner..." ); const final = await gateway . waitForCompletion ( result . workflowId ); console . log ( "✅ Epoch closed, rewards distributed" );
Workflow States PENDING → RUNNING → COMPLETED ↘ FAILED (unrecoverable) ↘ STALLED (can resume)
State Meaning PENDINGQueued, not yet started RUNNINGCurrently executing COMPLETEDSuccessfully finished FAILEDUnrecoverable error (e.g., contract revert) STALLEDRecoverable error (e.g., RPC timeout)
Monitoring Workflows Python
TypeScript / JavaScript
# Get current status status = gateway.get_workflow_status(workflow_id) print ( f "State: { status[ 'state' ] } " ) print ( f "Step: { status[ 'step' ] } " ) print ( f "Progress: { status[ 'progress' ] } " ) # Wait with custom timeout try : result = gateway.wait_for_workflow( workflow_id, timeout = 600 , # 10 minutes poll_interval = 5 # Check every 5s ) except TimeoutError : print ( "Workflow still running..." )
const status = await gateway . getWorkflow ( workflowId ); console . log ( "State:" , status . state ); console . log ( "Step:" , status . step ); console . log ( "Progress:" , status . progress ); try { await gateway . waitForCompletion ( workflowId , { maxWait: 10 * 60 * 1000 , pollInterval: 5 * 1000 , }); } catch ( err ) { console . log ( "Workflow still running..." ); }
Error Handling Python
TypeScript / JavaScript
from chaoschain_sdk.gateway_client import GatewayError try : result = gateway.submit_work( ... ) final = gateway.wait_for_workflow(result.workflow_id) except GatewayError as e: if e.state == "FAILED" : print ( f "❌ Unrecoverable: { e.error } " ) elif e.state == "STALLED" : print ( f "⚠️ Can retry: { e.error } " )
import { GatewayError , WorkflowFailedError } from "@chaoschain/sdk" ; try { const result = await gateway . submitWork ( /* ... */ ); await gateway . waitForCompletion ( result . workflowId ); } catch ( err ) { if ( err instanceof WorkflowFailedError ) { console . error ( "❌ Unrecoverable:" , err . message ); } else if ( err instanceof GatewayError ) { console . warn ( "⚠️ Gateway error:" , err . message ); } }

Protocol Isolation Explained Understanding this is critical for troubleshooting.
StudioProxy and RewardsDistributor are intentionally separate contracts :
Contract Handles StudioProxy Work submission, escrow, agent stakes RewardsDistributor Epoch management, consensus, rewards
The Gateway bridges this gap :
After submitWork() → calls registerWork() on RewardsDistributor
After score submission → calls registerValidator() on RewardsDistributor
closeEpoch() only succeeds if work and validators are registered
This is why workflows include REGISTER_WORK and REGISTER_VALIDATOR steps.
