Arbitrum: Kontrak Cerdas Pribadi yang Skalabel
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.

Pertanyaan yang Sering Diajukan
- Apa itu whitepaper Arbitrum?
- Whitepaper Arbitrum, berjudul 'Arbitrum: Scalable, Private Smart Contracts,' mendeskripsikan protokol optimistic rollup untuk skalabilitas Ethereum. Diterbitkan sebagai makalah USENIX Security pada tahun 2018, memperkenalkan interactive fraud proof untuk verifikasi komputasi off-chain.
- Siapa yang menulis whitepaper Arbitrum dan kapan?
- Whitepaper Arbitrum ditulis oleh Harry Kalodner, Steven Goldfeder, dan lainnya di Universitas Princeton. Diterbitkan pada tahun 2018, teknologi ini dikomersilkan oleh Offchain Labs, yang didirikan bersama oleh Ed Felten (mantan Deputy CTO Gedung Putih).
- Apa inovasi teknis utama Arbitrum?
- Inovasi utama Arbitrum adalah sistem interactive fraud proof — perselisihan diselesaikan melalui protokol biseksi multi-putaran yang mempersempit hingga satu instruksi tunggal, menjadikannya sangat efisien dalam hal gas untuk diverifikasi di Ethereum L1.
- Bagaimana mekanisme rollup Arbitrum bekerja?
- Arbitrum mengelompokkan transaksi off-chain dan memposting data terkompresi ke Ethereum L1. Sequencer mengurutkan transaksi dan mempublikasikan komitmen state. Siapa pun dapat menantang state root yang salah dengan memulai fraud proof selama periode tantangan ~7 hari.
- Apa perbedaan Arbitrum dengan Optimism?
- Arbitrum menggunakan interactive fraud proof (biseksi multi-putaran), sementara Optimism menggunakan non-interactive fraud proof (re-eksekusi langkah tunggal). Arbitrum memiliki lingkungan eksekusi AVM/WASM sendiri, sementara Optimism menggunakan EVM yang dimodifikasi (OP Stack).
- Bagaimana model pasokan ARB?
- ARB memiliki total pasokan 10 miliar token, dengan batas inflasi tahunan 2% untuk tata kelola DAO. Distribusi mencakup 42,78% untuk DAO treasury, 26,94% untuk investor, 17,53% untuk tim, dan 12,75% melalui airdrop awal.
- Apa saja kasus penggunaan utama Arbitrum?
- Arbitrum adalah Ethereum L2 terbesar berdasarkan TVL, menampung protokol DeFi utama (GMX, Camelot, Radiant), proyek NFT, dan gaming. Arbitrum Orbit memungkinkan proyek untuk meluncurkan chain L3 menggunakan tumpukan teknologi Arbitrum.
- Masalah apa yang diselesaikan Arbitrum?
- Arbitrum menyelesaikan biaya gas Ethereum yang tinggi dan throughput yang terbatas dengan mengeksekusi transaksi off-chain sambil mewarisi keamanan Ethereum. Pengguna mendapatkan biaya 10-100x lebih rendah dengan kompatibilitas smart contract yang sama.
- Bagaimana model keamanan Arbitrum bekerja?
- Keamanan Arbitrum mewarisi dari Ethereum L1 — data transaksi diposting ke Ethereum, dan satu validator jujur mana pun dapat menantang state root yang salah. Periode tantangan 7 hari memastikan waktu yang cukup untuk deteksi kecurangan.
- Bagaimana kondisi ekosistem Arbitrum saat ini?
- Arbitrum adalah Ethereum L2 terkemuka berdasarkan total value locked. Arbitrum One (rollup), Arbitrum Nova (AnyTrust untuk gaming/sosial), Stylus (smart contract WASM), dan Orbit (framework L3) membentuk tumpukan skalabilitas yang komprehensif. ArbitrumDAO mengatur pengembangan protokol.
