สรุป OP Stack และ Superchain

ภาพรวม OP Stack

OP Stack เป็นชุดซอฟต์แวร์โอเพนซอร์สที่ใช้สำหรับสร้าง Layer 2 blockchain บน Ethereum โดยใช้เทคโนโลยี Optimistic Rollups 4 OP Stack ถูกพัฒนาและดูแลโดย Optimism Collective เพื่อเป็นสาธารณูปโภคสำหรับระบบนิเวศ Ethereum และ Optimism 4

วิสัยทัศน์ของ Superchain

Superchain คือแนวคิดการปรับปรุงด้านการขยายตัวครั้งใหญ่ของ OP Stack หลังจาก Bedrock 1 โดยเป็นเครือข่ายของ chains ที่แบ่งปันระบบ bridging, การกำกับดูแลแบบกระจายอำนาจ, การอัปเกรด, และชั้นการสื่อสาร ซึ่งทั้งหมดสร้างบน OP Stack 1
