v0.20.0 — wPoA Testnet Launch

Shell-Chain v0.20.0 — wPoA Testnet Launch

This release activates the Weighted Proof of Authority (wPoA) consensus engine and launches the public testnet (chain_id=10).

Highlights

• wPoA consensus engine (W.1–W.7): Full production activation with weighted quorum ⌈2/3 × total_weight⌉, view-change protocol, 8 e2e tests
• shell_consensusInfo RPC (W.6): Live validator set + weights via JSON-RPC
• Two-layer peer scoring bridge (PS.1+PS.2): wPoA vote quality → network-level ban list (3 violations → 5-min ban)
• wPoA testnet genesis (T.1): chain_id=10, 3 validators, example file at examples/genesis-testnet-wpoa.json
• Testnet infra (T.2+T.7): infra/testnet/ docker-compose, Prometheus + Grafana dashboards
• RPC doc autogen (R.1–R.3): 75 methods, 7 namespaces, CI drift check

Network Parameters

v0.17.0

shell-chain v0.17.0

This release keeps the chain on v0.17.0 while closing the post-release sdk and wallet integration gaps.

Highlights:

• reject ambiguous SignedTransaction JSON payloads that mix sender_pubkey with pubkey_mode
• accept shell-sdk's current ML-DSA-65-produced Dilithium3 signatures as a compatibility fallback
• align shell_getNodeInfo and shell_getWitness with sdk/wallet typed contracts
• fix shell_getTransactionsByAddress.total to report the full match count
• add crypto, RPC, and receipt-visible e2e regressions for the sdk compatibility path

v0.16.0 — M14: Storage Profile Node Classification

What's New

Added

• --storage-profile <archive|full|light> — single flag replaces --body-retention / --witness-retention as the primary storage UX.

  Profile	TX bodies	PQ witnesses	State roots	~Daily write
  archive	forever	forever	forever	~12.8 GB/day
  full (default)	forever	128 blocks	forever	~1.5 GB/day
  light	4096 blocks (~2.3 h)	64 blocks	4096 blocks	~1 GB fixed

• StorageProfile enum with to_pruning_config() / from_pruning_config() / impl FromStr.

• StorageCapability P2P message — nodes advertise data-retention level on connect and startup.

• BodyRequest / BodyResponse P2P messages for historical body back-fill (128-block batches).

• HistoricalBodySync — automatic body back-fill on profile upgrade (e.g. light → full).

• NetworkTopic enum + NetworkMessage::topic() for safe libp2p message routing.

• ChainStore::has_body() and ChainStore::put_body_only() for selective body restore.

• Node::oldest_available_body_block() binary-search helper.

• Docker compose updated: node1=archive, node2/node3=full.

• New docs: BLOCK_PRUNING_AND_COMPRESSION.md storage profiles section.

Changed

• --body-retention / --witness-retention are now Option<u64> overrides; profile defaults apply when omitted.
• proof_replacement_grace is now profile-driven (0 for full/light, u64::MAX for archive).
• Node startup banner now shows active profile name and actual retention values.
• --pruning 0 (default) defers keep_recent to the profile default (light auto-sets 4096).

Bug Fixes (post-review)

• Fixed BodyResponse hash validation before storage (prevent malicious peer disk writes).
• Fixed sync stall when all batch hashes mismatch — first_gap tracking re-requests from first missing block.
• Fixed from_pruning_config() Full detection (was incorrectly matching some Light configs).
• Fixed banner profile classification to use from_pruning_config() consistently.
• BodyRequest handler warns about broadcast amplification (unicast API tracked as TODO).
