Scroll và EIP-4844: Ethereum Nâng Cấp Lớp Dữ Liệu Cho Rollups
Tại Sao Rollups Cần Lớp Dữ Liệu
Hãy đối mặt với điều này - câu chuyện mở rộng của Ethereum giống như phiên bản ‘Câu Chuyện Bất Tận’ của các nhà mật mã. Sau nhiều năm tranh luận, cộng đồng đã chọn rollups là giải pháp cho bài toán blockchain trilemma. Nhưng có một vấn đề: hầu hết rollups chỉ cần Ethereum làm một việc thật tốt - hoạt động như một lớp dữ liệu (DA) đáng tin cậy.
Ảo Tưởng Về Tính Toàn Vẹn Thực Thi
Cả ZK và optimistic rollups đều hứa hẹn tính toàn vẹn thực thi (tức là hợp đồng thông minh của bạn sẽ không gian lận). Nhưng có một bí mật nhỏ: bằng chứng thực thi không đảm bảo bạn có thể rút tiền nếu các nhà vận hành gian lận. Điều đó yêu cầu toàn bộ lịch sử trạng thái phải có sẵn - do đó cần DA.
EIP-4844: Nâng Cấp DA Của Ethereum
Hiện tại, rollups sử dụng calldata đắt đỏ cho DA. EIP-4844 giới thiệu ‘giao dịch mang blob’ - các đơn vị lưu trữ rẻ được thiết kế riêng cho DA. Đây là lý do:
- Tiết Kiệm Chi Phí: Dữ liệu blob rẻ hơn khoảng 80% so với calldata.
- Thị Trường Gas Riêng: Blob có thị trường phí riêng, giúp L2 không bị ảnh hưởng bởi tắc nghẽn L1.
- Tương Lai: Chuẩn bị cho Danksharding trong tương lai.

โอ้โห! อีเธอเรียมไม่หยุดอัพเกรด
จากบทความที่ว่า “Scroll and EIP-4844: How Ethereum is Leveling Up” เหมือนดูซีรี่ย์ต่อเนื่องไม่มีจบจริงๆ! ตอนนี้มาถึงซีซั่น “Data Availability” ที่ทั้ง ZK และ Optimistic rollups ต่างก็ร้องขอเหมือนเด็กอยากได้ขนม
ปัญหาคือไง?
- Optimistic rollups นี่เหมือนเพื่อนที่บอกว่า “เชื่อฉันดิ” แล้วเหงื่อแตก (ต้องคอยตามเช็คตลอด)
- ZK rollups ก็เหมือนอาจารย์เลขที่พิสูจน์ได้แต่…ก็ยังต้องการข้อมูลอยู่ดี!
EIP-4844 มาแก้ปัญหา ด้วย “blob-carrying transactions” ที่ช่วยลดค่าใช้จ่ายลง 80% - เหมือนไปตลาดแล้วได้ส่วนลดแบบจัดเต็ม!
สำหรับ Scroll ที่ใช้ zkEVM นี่เขาทำให้ระบบตรวจสอบ blob ได้ในวงจร…แม้จะกินทรัพยากรเครื่องไป 28M cells ก็ตาม (คอมผมคงร้องไห้แน่ๆ)
สรุปแล้วนี่คืออัพเดทที่ทั้งประหยัด ทั้งปลอดภัยกว่า - เหมาะกับคนขี้กังวลแบบผมที่ตรวจสอบสัญญาอยู่ดึกดื่น!
คิดยังไงบ้างครับ? คอมเมนต์ด้านล่างได้เลย!
Ethereum Finally Gets Its Act Together
After years of being the blockchain equivalent of that one friend who says ‘I’ll pay you back tomorrow’ (looking at you, optimistic rollups), Ethereum is finally stepping up its data availability game with EIP-4844.
Blobs to the Rescue
These magical ‘blob-carrying transactions’ are like switching from mailing bricks via UPS to sending holograms - 80% cheaper and way more efficient. Now if only dating apps had this kind of upgrade…
Pro Tip for Devs
If your zkEVM takes 139 seconds to verify a blob commitment, that’s exactly how long you should microwave popcorn for optimal kernel distribution. You’re welcome.
