nour v1.0.3 — Transpiled to Zeta + Full Test Suite

🥜 nour v1.0.3 — Pure Zeta

What Changed

Everything. The entire Bitcoin SV toolkit has been transpiled from Rust to pure Zeta.

Before	After
55 Rust files, 11,018 lines	52 Zeta files, 7,348 lines
Cargo.toml	zorb.toml
Rust on main	Zeta on main, Rust on rust branch
crates.io package	zorbs.io package

What You Get

Module	Size	What it does
address	92 lines	Base58 encode/decode (P2PKH, P2SH)
messages	1,847 lines	24 P2P message types (version, tx, block, inv, merkle...)
network	256 lines	Network configs + DNS seed iteration
peer	549 lines	TCP peer connections with message framing
script	2,491 lines	Full BSV script evaluator — opcodes, stack, BIP-62, CHECKMULTISIG
transaction	533 lines	P2PKH building, BIP-143 + legacy sighash
util	971 lines	Bloom filters, varint, bits, SHA256d, Hash160, reactive
wallet	550 lines	BIP-32 extended keys, BIP-39 mnemonics

Test Suite

3,185 lines of tests across 6 files covering all modules. Compiles to valid LLVM IR.

SIMD Note

Performance-critical paths leverage Zetans native SIMD via the dependency chain: @crypto/bsv58 (SIMD Base58), @crypto/bitcoin-hashes (SHA256/Hash160), @crypto/secp256k1 (ECDSA).

nour v1.0.2 — Padding fix, perf, bsv58 cleanup

v1.0.2

🐛 Bug Fix

• Little-endian padding bug in encode_num() and encode_bigint() — padding byte was inserted at the wrong position (beginning of LE array instead of end). Fixed in b9c3895.

⚡ Performance

• Rc-based interpreter stack — OP_DUP/OVER/PICK/TUCK now clone via atomic refcount increment instead of deep-copying up to 520B per operation. ~40 clone sites optimized.
• Bloom filter: reuse Cursor — reduces allocs from O(num_hash_funcs) to O(1).
• linked-hash-map → indexmap — actively maintained, faster hash map with predictable iteration order.

🔧 Maintenance

• Removed unused base58 dependency (fully migrated to bsv58)
• Full rustfmt + clippy pass — zero new warnings

nour v1.0.1 — Dependency audit, bsv58 replacement

Dependency Updates

• bitcoin_hashes 0.17.0 → 0.20.0
• rand 0.9.2 → 0.9.4
• ripemd 0.1.3 → 0.2.0
• criterion 0.7.0 → 0.8.2 (dev)

Changes

• Replaced base58 with bsv58 (optimized BSV codec — SIMD x86/ARM)
• Removed cargo-fuzz dev dependency (broken, no lib target)

Perf Audit (see prior analysis)

High-impact: VecDeque+Cow clone reduction in interpreter, BigInt→bytewise for bit ops, murmur3 reuse, pre-sized Vec allocations. Medium: linked-hash-map→indexmap, redundant SHA256d allocs.
