I remember i checked this node client from different discussion. But just like last time, it seems they haven't released the code or share any progress.
UTXO Engine
Hornet includes a custom, high-performance UTXO database designed for concurrent, high-throughput, out-of-order validation.
It provides lock-free concurrency for multiple readers and a single writer. It features native support for efficient reorg handling and out-of-order operations. Disk contention is minimized with efficient batching and high queue-depth async I/O requests. The index uses age-stratified, LSM-style tiers, compacted by concurrent background threads.
The engine integrates cleanly with the validation pipeline without the consensus library taking any dependency on the UTXO database layer.
This part is rather interesting, since UTXO growth makes initial sync on older/slower feels much longer. If/when it comes out, someone should compare how well it perform compared with Bitcoin on SSD with low RAM and HDD with high RAM.
Where libbitcoinkernel exposes Core’s consensus behavior for reuse, Hornet aims to specify consensus in an implementation-neutral form.
I wonder how would the the author compare their implementation with
https://github.com/libbitcoin/libbitcoin-consensus. AFAIK it's only dedicated library/module for Bitcoin consensus out there, since other full node software doesn't seem to provide such thing.
