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.

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.

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.

자주 묻는 질문
- Arbitrum 백서란 무엇인가요?
- Arbitrum 백서는 '확장 가능하고 프라이빗한 스마트 컨트랙트, Arbitrum'이라는 제목으로, 이더리움 확장을 위한 옵티미스틱 롤업 프로토콜을 설명합니다. 2018년 USENIX Security 논문으로 발표되었으며, 오프체인 계산 검증을 위한 인터랙티브 사기 증명을 소개합니다.
- Arbitrum 백서는 누가, 언제 작성했나요?
- Arbitrum 백서는 프린스턴 대학의 Harry Kalodner, Steven Goldfeder 등이 저술했습니다. 2018년에 발표되었으며, 이 기술은 전 백악관 부 CTO인 Ed Felten이 공동 창업한 Offchain Labs에 의해 상업화되었습니다.
- Arbitrum의 핵심 기술 혁신은 무엇인가요?
- Arbitrum의 핵심 혁신은 인터랙티브 사기 증명 시스템입니다. 분쟁은 다중 라운드 이분법 프로토콜을 통해 단일 명령어로 좁혀지며, 이더리움 L1에서 검증하는 데 매우 가스 효율적입니다.
- Arbitrum의 롤업 메커니즘은 어떻게 작동하나요?
- Arbitrum은 오프체인에서 트랜잭션을 묶어 압축된 데이터를 이더리움 L1에 게시합니다. 시퀀서가 트랜잭션 순서를 정하고 상태 커밋을 공개합니다. 누구든지 약 7일의 챌린지 기간 동안 사기 증명을 시작하여 잘못된 상태 루트에 이의를 제기할 수 있습니다.
- Arbitrum은 Optimism과 어떻게 다른가요?
- Arbitrum은 인터랙티브 사기 증명(다중 라운드 이분법)을 사용하고, Optimism은 비인터랙티브 사기 증명(단일 단계 재실행)을 사용합니다. Arbitrum은 자체 AVM/WASM 실행 환경을 갖추고 있으며, Optimism은 수정된 EVM(OP Stack)을 사용합니다.
- ARB의 공급 모델은 어떻게 되나요?
- ARB의 총 공급량은 100억 개이며, DAO 거버넌스에 연 2%의 인플레이션 상한이 있습니다. 분배 내역은 DAO 재무에 42.78%, 투자자에 26.94%, 팀에 17.53%, 초기 에어드랍으로 12.75%입니다.
- Arbitrum의 주요 사용 사례는 무엇인가요?
- Arbitrum은 TVL 기준 최대 이더리움 L2로, 주요 DeFi 프로토콜(GMX, Camelot, Radiant), NFT 프로젝트, 게임을 호스팅합니다. Arbitrum Orbit은 프로젝트들이 Arbitrum의 기술 스택을 사용하여 L3 체인을 출시할 수 있게 합니다.
- Arbitrum은 어떤 문제를 해결하나요?
- Arbitrum은 트랜잭션을 오프체인에서 실행하면서도 이더리움의 보안을 상속함으로써 이더리움의 높은 가스 비용과 제한된 처리량 문제를 해결합니다. 사용자는 동일한 스마트 컨트랙트 호환성을 유지하면서 10~100배 낮은 수수료를 누릴 수 있습니다.
- Arbitrum의 보안 모델은 어떻게 작동하나요?
- Arbitrum의 보안은 이더리움 L1에서 상속됩니다. 트랜잭션 데이터가 이더리움에 게시되며, 단 한 명의 정직한 검증자만 있어도 잘못된 상태 루트에 이의를 제기할 수 있습니다. 7일의 챌린지 기간은 사기 감지에 충분한 시간을 보장합니다.
- 현재 Arbitrum 생태계의 상태는 어떤가요?
- Arbitrum은 총 예치 가치 기준 선도적인 이더리움 L2입니다. Arbitrum One(롤업), Arbitrum Nova(게임/소셜용 AnyTrust), Stylus(WASM 스마트 컨트랙트), Orbit(L3 프레임워크)이 포괄적인 확장 스택을 형성합니다. ArbitrumDAO가 프로토콜 개발을 관장합니다.
