Bitcoin Razvijalec predstavlja Ark, protokol plasti 2 za hitra in učinkovita plačila
A Bitcoin developer by the name of pesa recently unveiled Ark, a Layer 2 protocol designed to enable fast and secure transactions. According to objava na 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 lastništva kovancev je izboljšana z omejitvijo vrednosti vTXO na razpon vrednosti sats. Uporabniki lahko pridobijo vTXO-je od drugih ali uporabijo postopek, imenovan lifting, ki jim omogoča, da svoje UTXO-je v verigi dvignejo iz verige za virtualne UTXO-je.
Protokol uvaja posrednika, imenovanega ponudnik storitev Ark (ASP), ki služi kot ponudnik likvidnosti, koordinator CoinJoin in ponudnik storitev Lightning. ASP-ji vsakih pet sekund ustvarijo hitre, slepe seje CoinJoin, znane kot bazeni, ki zagotavljajo atomičnost razporedov plačil. Prejemniki lahko zahtevajo svoja sredstva prek pogoja txlock, ki zahteva, da konektorska točka ostane nespremenjena.
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 omrežje.
