Changelog OmbraChain

Istoricul versiunilor protocol + apps (Wallet, Extension, miner-node).

Protocol​

v2.0 — Hard fork @ block #7500 (2026-04-12)​

Major upgrade — backward incompatible după FORK_HEIGHT.

Adăugat​

  • Proof of Token Used (PoTU) — fiecare bloc burns MAX(0.00001, totalTokens/10M) OMBRA
  • Validator Attestation — minimum 1 semnătură validator per bloc (Ed25519)
  • Reputation-weighted VRF — selecție validatori cu reputation^1.5
  • Stateless attestation target — hash(index|prevHash|proposer|txRoot|tokensBurned|tokensConsumed) (exclude stateRoot)
  • Proposer always eligible — proposer-ul e mereu primul în lista de validatori (liveness guarantee)
  • Fee split v2 — 70% miner / 25% burn / 5% validator (înlocuiește 70/20/5/5 v1)
  • BURN tx type — tx explicit pentru burn proposer
  • ATTESTATION_REWARD tx type — rezervat pentru rare cazuri payout explicit
  • block.attestations[] — array de semnături validatori
  • block.tokensBurned + block.tokensConsumed — câmpuri noi pentru audit

Modificat​

  • Reward miner acum (outputTokens + thinkingTokens) / 1,000,000 OMBRA (era coinbase 50 OMBRA fix)
  • Coinbase 50 OMBRA ELIMINAT — emisiune complet scalată cu munca AI realizată
  • Treasury 5% ELIMINAT din fee split (treasury rămâne ca address dar nu primește fee-uri noi)
  • Proposer 20% ELIMINAT din fee split (proposer-ul câștigă acum din attestation reward dacă self-atestă)

Hard fork​

  • Activ la FORK_HEIGHT = 7500
  • Sub 7500 — toate regulile v1 (PoAW Strict, coinbase 50)
  • ≥ 7500 — toate regulile v2 (PoATU + PoTU + Attestation)
  • Backward compat preserved — vechi nodes pot citi blocurile v2 ca read-only (dar nu produc/validează v2)

Bug fixes​

  • Self-attest pe mainnet (proposer nu era în VRF selected) — fixed prin proposerAddress parameter în selectValidators()
  • Attestation hash mismatch (stateRoot computed post-apply) — fixed prin computeAttestationTarget() stateless

v1.0 — Genesis → fork (2025-12 → 2026-04-12)​

Initial mainnet release.

Features​

  • Proof of AI Work Strict (PoAW) — task validation prin AI judges
  • Coinbase 50 OMBRA per bloc (cu halving la fiecare 210K blocks — never reached)
  • TASK_SUBMIT / TASK_REWARD flow
  • Fee split — 70% miner / 20% proposer / 5% validator / 5% treasury
  • Validator selection — reputation-based dar fără VRF
  • Reputation per miner — scor 0-1000

Ombra Wallet (Electron desktop)​

v0.3.0 — 2026-05-10​

  • Splash sync blocant — la prima deschidere, fereastră de progress în timp ce wallet-ul sincronizează cu mainnet
  • Bulk REST sync — descarcă blocuri prin REST (5-10 min) în loc de P2P slow
  • Fork local detection — verifică dacă chain local divergă de mainnet (genesis hash + sample blocks)
  • Hard reset chain dacă fork detectat (forțează re-sync clean)
  • Tab Mining — UI selector backend (Claude Code, Codex, Ollama, API key)
  • Tab Tasks — vezi task-urile tale (submitate + procesate)

v0.2.0 — 2026-04-20​

  • Transformare IDE → Wallet — eliminat Monaco editor + chat UI
  • Păstrate funcționalități: wallet, miner, validator, sync P2P
  • Eliminat MinerLoop local — wallet e PURE CLIENT (nu produce blocuri local — previne fork)
  • Sync exclusiv din mainnet — folosește seed peer + REST API

v0.1.0 — 2026-03-15​

  • Inițial fork din @ombrachain/ide — Electron app cu Monaco + AI chat

SDK (@ombrachain/sdk + ombrachain)​

v0.1.0 — 2026-05-18 (NOU)​

  • ombrachain lansat pe PyPI — Python ≥3.10 (REST + async WS/SSE + TxBuilder + Wallet + EncryptedStorage)
  • Cross-language compatibility — tx-uri semnate într-un SDK sunt bit-exact identice cu celălalt (vector tests OBLIGATORII)
  • 11 tx builders complete în ambele limbaje (TRANSFER, TASK_SUBMIT, TASK_RESPONSE, TASK_PROGRESS, TASK_VALIDATE, TASK_REWARD, MINER_REGISTER, NFT_SETNAME, NFT_TRANSFER, BURN, ATTESTATION_REWARD)
  • EncryptedStorage — AES-256-GCM + PBKDF2 100k iter, format blob identic TS/Python (export/import cross-tool)
  • CLI refactor — @ombrachain/cli (ombra binary) folosește acum SDK în loc de imports directe @ombrachain/core

Roadmap​

v2.1 (planificat Q3 2026)​

  • TASK_BATCH — submit multiple task-uri într-un singur tx

v2.2 (planificat Q4 2026)​

  • State pruning — full nodes pot șterge blocks vechi (light client mode)
  • Snapshot sync — boot rapid din snapshot oficial (fără re-sync genesis)
  • WASM smart contracts — execuție on-chain limited (read-only / view functions inițial)

v3.0 (long-term, 2027)​

  • Cross-chain bridge — OMBRA ↔ ETH/SOL pentru DeFi integration
  • Light client mobile — wallet iOS/Android cu light sync
  • Decentralized model marketplace — minerii publică modele Ollama custom
