Bitcoin Razvojni programer predstavlja Ark, protokol razine 2 za brza i učinkovita plaćanja
A Bitcoin developer by the name of repa recently unveiled Ark, a Layer 2 protocol designed to enable fast and secure transactions. According to a post on the Bitcoin dev mailing list, Ark offers an alternative scaling approach that allows users to send and receive funds without liquidity constraints, making it easier for recipients to get paid without an onboarding setup. Unlike other Layer 2 solutions like Lightning, Ark does not require the opening and closing of channels, reducing the on-chain footprint significantly.

Anonimnost vlasništva novčića poboljšana je ograničavanjem vTXO vrijednosti na raspon sats vrijednosti. Korisnici mogu nabaviti vTXO-ove od drugih ili koristiti proces koji se naziva podizanje, koji im omogućuje da svoje UTXO-ove u lancu podignu s lanca za virtualne UTXO-ove.
Protokol uvodi posrednika koji se zove Ark Service Provider (ASP), koji služi kao pružatelj likvidnosti, CoinJoin koordinator i pružatelj Lightning usluge. ASP-ovi stvaraju brze, slijepe CoinJoin sesije svakih pet sekundi, poznate kao skupovi, koji osiguravaju atomičnost rasporeda plaćanja. Primatelji mogu zatražiti svoja sredstva putem uvjeta txlock koji zahtijeva da izlazna točka konektora ostane nepromijenjena.
Ark's integration with the Lightning Network allows users to attach HTLCs (or PTLCs) to a pool transaction, enabling interoperability between the two protocols. Multiple ASPs can be used to pay Lightning invoices from different vTXO sources using multi-part payments. Payments on Ark are credited every five seconds, allowing users to spend their zero-conf vTXOs immediately without waiting for on-chain confirmations.
The developer behind Ark highlighted the protocol's potential for future extensions and improvements. A hypothetical data manipulation opcode could disincentivize double-spending, and users could forge an ASP's signature to reclaim their vTXOs in case of a double-spend. Overall, Ark offers a promising solution for efficient and secure off-chain transactions on the Bitcoin mreža.
