Phase 1 Execution Brief – Consensus Network Foundation¶
This living brief documents the concrete deliverables completed during Phase 1 so engineering, governance, and mobilization teams remain synchronized while the DATU validator network comes online.
Validator Configuration Snapshot¶
| Validator | Tier | Public Key | History Archive | Role Notes |
|---|---|---|---|---|
datu-tier0-foundation |
Tier 0 (foundation steward) | GBVHRGLHPCZHHP47DY7WKOAFLKJEIF67O7L7O42OGWIJDITCSOXWEINY |
s3://history.datu.foundation/core-foundation/ |
Custodian for the passphrase, anchors quorum intersection, and funds emergency recovery. |
datu-tier1-east |
Tier 1 (government agency) | GBHV6GP2UPHIQ27T5ANAU6ZQ23L7JFQLWZTIXEV4VXJT32J7Z6X7QR7E |
s3://history.datu.foundation/core-east/ |
Primary operator responsible for day-to-day ledger management and release coordination. |
datu-tier1-west |
Tier 1 (government agency) | GDUMHIOUG57CUX3BNBTWTNL5C7TBZO3N5LA4H4S67YHKYBNO22RKWPQ7 |
s3://history.datu.foundation/core-west/ |
Provides geographic redundancy and hosts the first production-grade Horizon endpoint. |
datu-tier1-south |
Tier 1 (civil society) | GD7KIZSLIA6Z5GXJW3I64DWTN7PX7TYVMY4PDLVXS53ANN253SXVJJCK |
s3://history.datu.foundation/core-south/ |
Operated by the civic-oversight coalition to guarantee public transparency. |
datu-tier2-audit |
Tier 2 (independent auditor) | GDPCADHCULMM34TAB54G2CUC7K26ID7DNKSCK76DQY2QBTY2E7BUMJGL |
s3://history.datu.foundation/core-audit/ |
Mirrors ledgers for compliance review and crisis recovery without voting weight during normal operations. |
The validator roster is encoded in infrastructure/stellar-fork/config/quorumsets.toml
and infrastructure/stellar-fork/config/stellar-core.cfg. Failure safety has been raised to 1
and UNSAFE_QUORUM disabled so consensus now requires supermajority agreement across independent operators.
Soroban Enablement¶
- Execution budgets now reflect production needs: the Soroban config raises CPU instructions to
240,000,000, memory to12 MB, and ledger read/write limits accordingly. These values match theMAX_SOROBAN_INVOKE_HOST_FUNCTIONSoverride instellar-core.cfgto avoid runtime mismatches. Seeinfrastructure/stellar-fork/config/soroban.toml. - Diagnostics are fully enabled with JSON and Prometheus export, plus 14-day event retention and 30-day metric retention to support the observability program tracked in Phase 6.
- Cost multipliers (
compute=1.0,io=1.2) are documented so CI can reproduce production execution caps during contract testing.
Initial Testnet Deployment Plan¶
| Milestone | Target Date | Owner | Key Outputs |
|---|---|---|---|
| Local quorum rehearsal | 2025-10-15 | Consensus engineering | Launch additional compose profiles to simulate Tier 1/2 validators and validate quorum behaviour. |
| Remote archive dry run | 2025-10-17 | DevOps + validator operators | Stand up S3 buckets per operator and test catchup from archival history. |
| Public RPC preview | 2025-10-21 | Horizon team | Publish Horizon + Soroban RPC endpoint backed by datu-tier1-west, integrate Friendbot funding from integration account. |
| DATU Testnet v1 announcement | 2025-10-24 | Steering committee | Release validator onboarding packet, publish public documentation, and open civic-feedback channels. |
Pre-funded accounts supporting the rollout (Friendbot, QA scenarios, validator bonds, compliance reserve) are listed in
config/accounts.json with their controlling signers. The deployment remains in the
local-only phase until the history archives and onboarding packet tasks in the checklist are marked complete.
Mobilization Backlog Alignment¶
| Technical Deliverable | Mobilization Owner | Dependency Description |
|---|---|---|
| Validator roster & quorum policy | Governance working group chair | Requires steering committee ratification and publication to fulfill Phase 0 charter commitments. |
| Soroban execution budget | Compliance liaison | Needs privacy impact and procurement review to confirm resource usage stays within approved envelopes. |
| Pre-funded account catalogue | Treasury controller | Supports financial oversight and anti-corruption reporting obligations captured in the mobilization backlog. |
| Testnet deployment milestones | Project coordinator | Drives cross-team updates in weekly status reports until Phase 0 exit criteria close. |
Owners have acknowledged these dependencies in the shared backlog, and twice-weekly syncs are scheduled every Tuesday/Friday to clear any regulatory or tooling blockers before the public testnet announcement.
Risk Register Touchpoints¶
- History archive readiness – Remote S3 buckets are not yet provisioned. Mitigation: DevOps to prototype archive automation by 2025-10-17 and document retention policies before remote validators join.
- Validator onboarding packet – Drafting in progress. Mitigation: steering committee communications lead owns the packet and will circulate a review draft alongside the DATU Testnet v1 announcement prep on 2025-10-21.
- Soroban cost drift – Changes to execution budgets require compliance sign-off. Mitigation: compliance liaison participates in Phase 1 syncs and tracks approvals in the mobilization backlog tracker.
Progress updates will continue to be captured in this brief and the running Project Progress changelog as additional checklist items close.
