From caf13a193747ea0e9e4aeabbd705c2af9742e728 Mon Sep 17 00:00:00 2001 From: Claude Date: Thu, 2 Apr 2026 00:10:42 +0100 Subject: [PATCH] feat(blockchain): full testnet sync, RPC daemon, wallet CLI, alias extraction MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - wire: add readExtraAliasEntry (tag 33) + readExtraAliasEntryOld (tag 20) Unblocks HF4+ Zarcanum transaction deserialization - chain: alias extraction from transaction extra fields (14/14 on testnet) - chain: alias storage and retrieval via go-store - daemon: JSON-RPC server (getinfo, getheight, getblockheaderbyheight, getlastblockheader, get_all_alias_details, get_alias_details) - cmd: `chain serve` — sync from seed + serve RPC simultaneously - cmd: `wallet create` — generate keys, iTHN address, 24-word seed - cmd: `wallet address` — show base58-encoded iTHN address - cmd: `wallet seed` — show mnemonic seed phrase - cmd: `wallet scan` — scan chain for owned outputs via ECDH derivation Tested: 11,263 blocks synced in 3m11s from live testnet. All HF0-HF4 validated. 14 aliases extracted. RPC serves correct heights, difficulties, block headers, and alias data. Wallet generates valid iTHN addresses.
