Infrastructure & Operations

  • Client upgrades (all zero-downtime via hot-swap on Singapore primary + Dallas failover):
    • jito-solana 4.2.0-jito on the voting fleet (August 10, 2026)
    • jito-solana 4.2.1-jito on the voting fleet; Agave 4.2.1 on the NCN governance RPC (Los Angeles) and the Solana RPC node (August 14, 2026) — full mainnet fleet on 4.2.1 at month end
    • NCN governance RPC (Los Angeles): stock Agave 4.1.1 → 4.1.2 (August 3) → 4.2.0 (August 11) → 4.2.1 (August 14) — stock Agave required for valid governance snapshots
    • Solana RPC node: migrated from Xandeum-Agave 4.1.0x to stock Agave (August 2, 2026) as the Xandeum docks were retired; then 4.2.0 (August 11) → 4.2.1 (August 14)
  • NCN governance stack (Los Angeles): svmgov 0.3.0-40000 → 0.4.0-40100 (August 2; on-chain program migrated to the new governance program ID) · ncn-cli → 0.4.0-40100 (August 3) · both to 0.5.0-40200 (August 21). Verifier service rebuilt to the current upstream revision.
  • DoubleZero fleet upgrades: mainnet fleet synchronized on v0.33.0 (August 6); testnet (Reston) to v0.36.0 (August 14) — testnet-first pattern maintained
  • Testnet client (Reston): Frankendancer hybrid path maintained, v0.1104.40200 → v0.1106.40201 (August 19)
  • Alpenglow community cluster: cluster reset August 8 (Agave 4.3.0, new feature set); Digital Energy rejoined and remained a voting participant through month end
  • Solana RPC node — account indexes live (August 14): program-id + spl-token-owner indexes in production; getProgramAccounts, getTokenAccountsByOwner, getTokenAccountsByDelegate enabled on the commercial endpoint
  • RPC incident and hardening (August 15): validator process self-exited and auto-restarted; ~66 minutes of degraded service during index rebuild and catch-up. Post-incident hardening applied (memory limits, reduced snapshot cadence, out-of-band restart detection in the health check).

Ecosystem Participation

  • NCN Governance (solana-foundation/solana-governance):

    • Live SGP vote round completed — round 1020 (August 21, 2026): slot 440,641,000 · 783 vote accounts / 1,186,894 stake accounts · merkle root 2Jwjfi6KWQmqMraTkCcWqdj3VvyGcVgfNGYdzTQmaUj8 · verifier proof confirmed on-chain · operator vote finalized at slot 440,695,063 · Digital Energy was operator #10 of 11 to reach consensus. Snapshot source: stock Agave NCN RPC (Los Angeles), never the Jito fork.
    • SGP votes cast — YES on all three: SGP-0001 (Solana Constitution) · SGP-0002 (Double Disinflation / SIMD-0550) · SGP-0003 (Resource and Inclusion Fee / SIMD-0553). ~296K SOL stake weight; voting window epochs 1021–1024.
    • End-to-end pipeline validation on mainnet (August 3–4): slot 437,036,500 · 792 vote accounts / 1,221,305 stake accounts · proof depth 10 · verifier upgraded 0.1.6 → 0.4.0-40100. Root-caused a misleading "Missing snapshot at slot X" failure to a discarded bank-load error and fixed it upstream (PR #125).
    • PR campaign completed — 12 PRs merged in August (14 lifetime): #125 (Aug 4, first code PR: propagate get_bank_from_ledger errors) · #15, #16, #17, #29, #30, #130 (Aug 5) · #34, #35, #36 (Aug 6) · #55 (Aug 7 UTC — snapshot-slot recovery procedure, genesis-copy and disk-budget pre-flights, and a failure quick-reference table now in the official repo docs) · #208 (Aug 31 — corrected verifier-service upload signature preimage and metrics token header). Reviews by Tim Garcia, MicaiahReid and tiago18c. Lifetime: 14 merged · 2 closed-unmerged · 0 open.
    • Issue #185 filed (August 24): dashboard Vote Accounts table UX during a live SGP vote (missing proposal/ballot columns, search, and zero-value display defects). solana-foundation/solana-governance#185
    • NCN Operator Playbook published (August 5): sanitized field notes covering the full round pipeline, disk-budget and genesis-copy pre-flights, and a failure table. https://gist.github.com/Digitalenergyllc/51560bebc9b1c3d7b07d5a645ff03b73

Live figures at publish time are in the August entry above.

Infrastructure & Operations

  • Client upgrades (all zero-downtime via hot-swap on Singapore primary + Dallas failover):
    • jito-solana 4.1.0-jito (June 29, 2026) → 4.1.1-jito (July 7) → 4.1.2-jito (July 15)
    • NCN governance RPC (Los Angeles): stock Agave 4.1.0 → 4.1.1 (July 8) — stock Agave required for valid governance snapshots
    • Xandeum RPC node (Chicago): Xandeum-Agave 4.0.3x → 4.1.0x (July 9). The node went offline in the SIMD-0387 fork event on July 8 and was recovered on 4.1.0x on July 9.

  • Testnet client (Reston): migrated from Frankendancer hybrid to full Firedancer v1.1.1 (July 17; Agave sidecar removed, identity/vote keys preserved). Rolled back to Frankendancer v0.1102.40201 on July 21 per Anza testnet incident guidance (superminority delinquency across a majority of testnet validators). Rollback is the standard protocol response.
  • Solana commercial RPC portal launched (July 27): rpc.digital-energy.io live alongside xandeum-rpc.digital-energy.io; index-method gate in production (non-indexed methods return -32601).

Ecosystem Participation

  • NCN Governance (solana-foundation/solana-governance):

    • Contribution footprint unchanged through July at 24 total (13 PRs, 11 issues). The 10-PR documentation stack was rebased and prepared for review; commit signing was enabled at the maintainers' request on August 4, after which the stack merged (see August entry).

  • Digital Energy X content — 2 posts/week cadence + QRT lane (posts #31–#58, July 2026). Selected posts:

  • JagPool:

    • Direct Stake captured (July 29): holder-directed matching layer — Digital Energy directive active at epoch 1009; +1,000 SOL of directed matching to the Singapore primary. Posted publicly with a link to the JagPool direct-stake page; the APAC regional budget went from ~2,000 SOL remaining to under 100 within days.
    • Shred Publisher tier sunset: the bloXroute shred-stream partnership behind JagPool's Shred Publisher tier wound down in July (bloXroute was acquired by FalconX on July 15); shred publishing to bloXroute endpoints was removed from the Singapore primary on July 31. DoubleZero Edge multicast publishing is a separate path and continues.

    • Diagnosed and recovered from an await-snapshot coverage-gap edge case using a manual snapshot-slot replay path; hardened the node's snapshot-retention config to prevent recurrence.
    • Filed PR #55 to solana-foundation/solana-governance (open) — documents the snapshot-slot recovery procedure and clarifies the generate-meta-merkle full-snapshot path flag. Complements PR #52 (tomjohn1028, merged 5/28), which clarifies the await-snapshot message; #55 covers the recovery procedure the message points toward.
    • Reported two operator gotchas to the NCN cohort: (1) generate-meta-merkle ignores --full-snapshots-path (uses --backup-snapshots-dir); (2) all-in-one await-snapshot flow panics on a jito-solana accounts-db shrink assertion when validator runs during snapshot capture — split workflow is the working pattern.
    • Standing rule confirmed: stock Agave (not Jito fork) is required for valid governance snapshots.
    • GitHub-verified cumulative footprint: 24 total contributions — 13 PRs (11 open, 2 merged: #14 + #31) + 11 issues (10 open, 1 closed: #19, resolved by merged PR #31).

  • DoubleZero Ambassador (Tier 1 Technical Writer + Day-1 Edge Publisher since 3/26/2026):

  • Alpenglow Community Cluster (early participation):

    • Generated fresh isolated identity + vote keys (5/15); pubkeys submitted to Tim Garcia (Solana Foundation, SFDP lead) to correct original Google Form.
    • Identity yTZrP6niRU1YqxrU4i1dc1PRxRA9poYA4ZexkqPbTCa / Vote 9zETKewk74Qz1w1b5cVjpsqdcupQW2MXJdpeYgsArmMU.
    • Validator stood up on OVH Vint Hill (5/29); voting on community cluster; validator-info published as "Digital Energy (Alpenglow)" — ValidBlocks indexed.
    • Not a mainnet stake delegation — testnet participation only.

  • Xandeum: 6 pNodes maintained (4.70 TB mainnet + 161 GB devnet). xandeum-rpc.digital-energy.io continued production operation on Xandeum-Agave 3.1.13x.

  • BAM Operations: BAM Boost active across 11 May epochs (lifetime claimed 49.89 JitoSOL since epoch 912 across 69 epochs; May 11-epoch rolling avg 0.68 JitoSOL/epoch; last 3 epochs 0.64 JitoSOL avg).

Development & Tooling

  • digital-energy.io landing page refreshed (5/28) — new hero with live validator stats, "Why Stake With Us," ecosystem-participation section, digitalSOL token panel, operator bio. Funded entirely by validator rewards (Digisol M3 + landing-page milestones paid in SOL 5/29; M4 RPC Portal Core scope kicked off).
  • app.digital-energy.io/validator-performance live (5/28) — single consolidated public + institutional metrics surface: live performance gauges, per-epoch Rewards model (leader / commission / Jito / voting fee / net, sourced from svt.one), curated stake delegation breakdown, identity & vote-account balances, TrueAPY, live-computed epoch count, corrected leader-slot skip count. "Active Across the Solana Ecosystem" panel surfaces DoubleZero (Ambassador & Edge), Jito BAM, NCN Governance, Xandeum RPC, SFDP — transparency surface for institutional delegators.
  • NCN Operator Reference gist refreshed (5/28) — gist/622602ec... updated with sanitized snapshot + MetaMerkle generation runbook reflecting the v4 await-snapshot / split-workflow patterns discovered during the end-to-end mainnet round.

Artifacts Updated

Next (planned — June 2026)

  • JitoSOL StakeNet pivot at epoch 980 — monitor delegation activation under JIP-28 gates.
  • Phase Delegation Q2 contribution report (due 7/31/2026) — first quarterly submission.
  • DynoSOL Q2 quarterly CG submission (due ~6/30/2026).
  • Sustain DoubleZero Ambassador weekly cadence; carryover ideas include DZ v0.24.0 fleet-rollout-complete, NCN v4 first-in-cohort feature, 528+ epoch milestone.
  • JagPool CG + Performance + Snapshot Provider tier maintenance + delta delegation toward 5,431 SOL portal target.

2026-05-01 (April Update)

Validator status (live, epoch 965): Rank #364 · 258,185.90 SOL stake · 100% uptime (30d) · 0% skip · credit ratio 94.1% · Solana 3.1.14-jito · Singapore · 514 consecutive epochs since epoch 451 (March 2023). Verified StakeWiz API at publish time.

Infrastructure & Operations

  • Solana client upgrades, all zero-downtime via hot-swap protocol on Singapore primary + Dallas failover: 3.1.10-jito → 3.1.12-jito (April 6) → 3.1.13-jito (April 10) → 3.1.14-jito (April 28). Total perceived downtime across all 3 upgrades: 0 slots, 0 missed votes.
  • DoubleZero agent fleet alignment: v0.16.0 → v0.17.0 → v0.18.0 → v0.19.0 progressive rollout completed April 29 across all 4 mainnet servers (Singapore primary, Dallas failover, Chicago RPC, LA NCN RPC).
  • Testnet-first DZ rollout pattern continued on Reston testnet: v0.18.0 → v0.19.0 (April 24) → v0.20.0 (April 30). Mainnet upgrade to v0.20.0 follows after standard validation period.
  • Testnet client diversity: Reston testnet upgraded to Frankendancer v0.906.40000 (April 27).
  • Implemented 5% inflation commission (epoch 949, 3/30/2026). MEV commission remains 0%. Rank rebalancing and pool reconfiguration tracked separately.

Chicago Xandeum RPC — major hardening sprint (April 29-30)

  • Recovered Chicago RPC from an operational incident via snapshot restore (root-cause forensic deferred).
  • Built and deployed xandeum-agave 3.1.13x from source, working around an upstream private-submodule blocker. Verified agave-validator 3.1.13 (client:Xandeum). Caught up. getHealth=ok.
  • Identified and fixed a systemd Dock dependency bug affecting Xandeum operators. Altair/Vega Dock units had Requires=xandeum-rpc.service but no PartOf=/Wants= reverse dependency, so they tore down with validator restart but never came back up automatically. Fixed locally (BindsTo + PartOf + Wants), verified, and flagged to Brad/Solana Foundation engineering for fleet-wide remediation. Workaround documented in the rpc-operations Discord for other operators.
  • Deployed per-IP rate limiting and concurrent-connection floor on the public RPC endpoint. Verified under load.
  • Xandeum metrics integration live — required for Xandeum RPC Grant Program participation; readiness summary submitted to Brad.
  • Public RPC endpoint security architecture documented and hardened — TLS, rate limiting, network isolation, and a pre-launch CDN cutover runbook prepared for the M5 deploy window.
  • Endpoint live: https://xandeum-rpc.digital-energy.io

Stakeholder Reporting & Program Engagement

  • DynoSOL + JagPool CG Monthly Report submitted April 22, 2026.

Stake Delegation & Pipeline

  • Phase Delegation: APPLIED April 6 → ACCEPTED April 22. 25 SOL refundable bond minted, IPS 183/1000. Phase ceiling raised 250K → 300K SOL during April. Expected delegation 5-14K SOL post-onboarding; quarterly contribution review required.
  • JagPool jag-snap Snapshot Provider live (April 6) — Snapshot Provider service deployed and verified, 2nd APAC snapshot provider on the JagPool network. Auto-detected by JagPool. Snapshot Provider tier added: +1,603 SOL. Total JagPool stake now 5,591 SOL across three tiers — Community Goods 1,642 SOL (29%), Performance 2,346 SOL (42%), Snapshot Provider 1,603 SOL (29%).
  • JitoSOL pipeline ON HOLD — per Jito (April 4), JIP-28 requires 0% inflation commission, which our 5% disqualifies until BAM reaches 30% network stake weight. Pipeline target paused.
  • StarPool removed from active pipeline (no engagement after 20 days).
  • Solana Foundation SFDP: 65,850 SOL current → 66,319 SOL planned. New SFDP requirements effective May 1, 2026 — vote subsidy expired.
