Overview
Arbitrum: Scalable, private smart contracts | USENIX Registration Information Registration Discounts Student and Diversity Grants Venue, Hotel, and Travel Birds-of-a-Feather Sessions Poster Session and Happy Hour Submission Policies and Instructions Instructions for Presenters Arbitrum: Scalable, private smart contracts Harry Kalodner, Steven Goldfeder, Xiaoqi Chen, S. Matthew Weinberg, and Edward W. Felten, We present Arbitrum, a cryptocurrency system that supports smart contracts without the limitations of scalability and privacy of systems previous systems such as Ethereum. Arbitrum, like Ethereum, allows parties to create smart contracts by using code to specify the behavior of a virtual machine (VM) that implements the contract's functionality. Arbitrum uses mechanism design to incentivize parties to agree off-chain on what a VM would do, so that the Arbitrum miners need only verify digital signatures to confirm that parties have agreed on a VM's behavior. In the event that the parties cannot reach unanimous agreement off-chain, Arbitrum still allows honest parties to advance the VM state on-chain. If a party tries to lie about a VM's behavior, the verifier (or miners) will identify and penalize the dishonest party by using a highly-efficient challenge-based protocol that exploits features of the Arbitrum virtual machine architecture. Moving the verification of VMs' behavior off-chain in this way provides dramatic improvements in scalability and privacy. We describe Arbitrum's protocol and virtual machine architecture, and we present a working prototype implementation. USENIX is committed to Open Access to the research presented at our events.

In the event that the parties cannot reach unanimous agreement off-chain, Arbitrum still allows honest parties to advance the VM state on-chain. If a party tries to lie about a VM's behavior, the verifier (or miners) will identify and penalize the dishonest party by using a highly-efficient challenge-based protocol that exploits features of the Arbitrum virtual machine architecture. Moving the verification of VMs' behavior off-chain in this way provides dramatic improvements in scalability and privacy. We describe Arbitrum's protocol and virtual machine architecture, and we present a working prototype implementation. USENIX is committed to Open Access to the research presented at our events.

Matthew Weinberg, and Edward W.

Arbitrum, like Ethereum, allows parties to create smart contracts by using code to specify the behavior of a virtual machine (VM) that implements the contract's functionality. Arbitrum uses mechanism design to incentivize parties to agree off-chain on what a VM would do, so that the Arbitrum miners need only verify digital signatures to confirm that parties have agreed on a VM's behavior. In the event that the parties cannot reach unanimous agreement off-chain, Arbitrum still allows honest parties to advance the VM state on-chain. If a party tries to lie about a VM's behavior, the verifier (or miners) will identify and penalize the dishonest party by using a highly-efficient challenge-based protocol that exploits features of the Arbitrum virtual machine architecture.

Arbitrum: Scalable, private smart contracts | USENIX Registration Information Registration Discounts Student and Diversity Grants Venue, Hotel, and Travel Birds-of-a-Feather Sessions Poster Session and Happy Hour Submission Policies and Instructions Instructions for Presenters Arbitrum: Scalable, private smart contracts Harry Kalodner, Steven Goldfeder, Xiaoqi Chen, S. Matthew Weinberg, and Edward W. Felten, We present Arbitrum, a cryptocurrency system that supports smart contracts without the limitations of scalability and privacy of systems previous systems such as Ethereum. Arbitrum, like Ethereum, allows parties to create smart contracts by using code to specify the behavior of a virtual machine (VM) that implements the contract's functionality. Arbitrum uses mechanism design to incentivize parties to agree off-chain on what a VM would do, so that the Arbitrum miners need only verify digital signatures to confirm that parties have agreed on a VM's behavior. In the event that the parties cannot reach unanimous agreement off-chain, Arbitrum still allows honest parties to advance the VM state on-chain. If a party tries to lie about a VM's behavior, the verifier (or miners) will identify and penalize the dishonest party by using a highly-efficient challenge-based protocol that exploits features of the Arbitrum virtual machine architecture. Moving the verification of VMs' behavior off-chain in this way provides dramatic improvements in scalability and privacy. We describe Arbitrum's protocol and virtual machine architecture, and we present a working prototype implementation. USENIX is committed to Open Access to the research presented at our events.

Arbitrum: Scalable, private smart contracts | USENIX Registration Information Registration Discounts Student and Diversity Grants Venue, Hotel, and Travel Birds-of-a-Feather Sessions Poster Session and Happy Hour Submission Policies and Instructions Instructions for Presenters Arbitrum: Scalable, private smart contracts Harry Kalodner, Steven Goldfeder, Xiaoqi Chen, S. Matthew Weinberg, and Edward W. Felten, We present Arbitrum, a cryptocurrency system that supports smart contracts without the limitations of scalability and privacy of systems previous systems such as Ethereum. Arbitrum, like Ethereum, allows parties to create smart contracts by using code to specify the behavior of a virtual machine (VM) that implements the contract's functionality. Arbitrum uses mechanism design to incentivize parties to agree off-chain on what a VM would do, so that the Arbitrum miners need only verify digital signatures to confirm that parties have agreed on a VM's behavior. In the event that the parties cannot reach unanimous agreement off-chain, Arbitrum still allows honest parties to advance the VM state on-chain. If a party tries to lie about a VM's behavior, the verifier (or miners) will identify and penalize the dishonest party by using a highly-efficient challenge-based protocol that exploits features of the Arbitrum virtual machine architecture. Moving the verification of VMs' behavior off-chain in this way provides dramatic improvements in scalability and privacy. We describe Arbitrum's protocol and virtual machine architecture, and we present a working prototype implementation. USENIX is committed to Open Access to the research presented at our events.

Sık Sorulan Sorular
- Arbitrum teknik dokümanı nedir?
- "Arbitrum: Ölçeklenebilir, Özel Akıllı Sözleşmeler" başlıklı Arbitrum teknik dokümanı, Ethereum ölçeklendirme için bir iyimser rollup protokolünü açıklar. 2018'de USENIX Security makalesi olarak yayımlanan bu belge, zincir dışı hesaplama doğrulaması için etkileşimli sahtekârlık kanıtlarını tanıtır.
- Arbitrum teknik dokümanını kim yazdı ve ne zaman?
- Arbitrum teknik dokümanı, Princeton Üniversitesi'nden Harry Kalodner, Steven Goldfeder ve diğerleri tarafından yazıldı. 2018'de yayımlanan bu teknoloji, eski Beyaz Saray Başkan Yardımcısı CTO'su Ed Felten'in kurucu ortaklığını yaptığı Offchain Labs tarafından ticarileştirildi.
- Arbitrum'un temel teknik yeniliği nedir?
- Arbitrum'un temel yeniliği, etkileşimli sahtekârlık kanıtı sistemidir. Anlaşmazlıklar, tek bir talimata kadar daraltılan çok turlu ikiye bölme protokolüyle çözülür; bu yöntem, Ethereum L1 üzerinde doğrulamayı son derece az gas kullanır hale getirir.
- Arbitrum'un rollup mekanizması nasıl çalışır?
- Arbitrum, işlemleri zincir dışında toplu hale getirir ve sıkıştırılmış verileri Ethereum L1'e gönderir. Bir sıralayıcı (sequencer), işlemleri sıralar ve durum taahhütlerini yayımlar. Yaklaşık 7 günlük itiraz süresi boyunca herhangi biri, yanlış durum köklerine sahtekârlık kanıtı başlatarak itiraz edebilir.
- Arbitrum, Optimism'den nasıl farklıdır?
- Arbitrum çok turlu ikiye bölme ile etkileşimli sahtekârlık kanıtları kullanırken Optimism tek adımlı yeniden yürütmeyle etkileşimsiz sahtekârlık kanıtları kullanır. Arbitrum'un kendi AVM/WASM yürütme ortamı varken Optimism değiştirilmiş bir EVM (OP Stack) kullanır.
- ARB'nin arz modeli nedir?
- ARB'nin toplam arzı 10 milyar token olup DAO yönetişimi için yıllık %2 enflasyon tavanı uygulanır. Dağılım şöyle planlanmıştır: %42,78 DAO hazinesi, %26,94 yatırımcılar, %17,53 ekip ve %12,75 ilk airdrop aracılığıyla.
- Arbitrum'un birincil kullanım alanları nelerdir?
- Arbitrum, TVL açısından en büyük Ethereum L2'sidir ve büyük DeFi protokollerine (GMX, Camelot, Radiant), NFT projelerine ve oyun uygulamalarına ev sahipliği yapar. Arbitrum Orbit, projelerin Arbitrum'un teknoloji altyapısını kullanarak L3 zincirleri başlatmasına olanak tanır.
- Arbitrum hangi sorunu çözüyor?
- Arbitrum, Ethereum'un yüksek gas ücretleri ve sınırlı verim sorununu, işlemleri zincir dışında yürütürken Ethereum'un güvenliğini miras alarak çözüyor. Kullanıcılar, aynı akıllı sözleşme uyumluluğuyla 10-100 kat daha düşük ücretler elde ediyor.
- Arbitrum'un güvenlik modeli nasıl çalışır?
- Arbitrum'un güvenliği Ethereum L1'den miras alınır. İşlem verileri Ethereum'a gönderilir ve tek bir dürüst doğrulayıcı, yanlış durum köklerine itiraz edebilir. 7 günlük itiraz süresi, sahtekârlığın tespiti için yeterli zaman sağlar.
- Arbitrum ekosisteminin güncel durumu nedir?
- Arbitrum, toplam kilitli değer açısından önde gelen Ethereum L2'sidir. Arbitrum One (rollup), Arbitrum Nova (oyun/sosyal için AnyTrust), Stylus (WASM akıllı sözleşmeleri) ve Orbit (L3 çerçevesi) kapsamlı bir ölçeklendirme yığını oluşturuyor. ArbitrumDAO, protokol geliştirmeyi yönetiyor.
