The Central Dogma01:20

The Central Dogma

19.9K
The central dogma explains the flow of genetic information from DNA nucleotides to the amino acid sequence of proteins.
RNA is the Missing Link Between DNA and Proteins
In the early 1900s, scientists discovered that DNA stores all the information needed for cellular functions and that proteins perform most of these functions. However, the mechanisms of converting genetic information into functional proteins remained unknown for many years. Initially, it was believed that a single gene is...

科学领域:

  • 农业科学 农业科学
  • 计算机科学 计算机科学
  • 供应链管理 供应链管理

背景情况:

  • 农业食品安全是全球关注的问题,区块链技术 (BCT) 提高了对农业食品供应链可追溯系统 (AFSCTS) 的信任.
  • 基于BCT的AFSCTS的线性数据增长造成了存储瓶,并增加了设备需求.

研究的目的:

  • 提出一种新的AFSCTS架构,可以降低存储压力,同时保持可追溯性.
  • 解决传统区块链可追溯系统中持续数据增长的局限性.

主要方法:

  • 开发了一种轻量级可负责任的并行区块链架构 (LAP-chain),集成可编辑的区块链和星际文件系统 (IPFS).
  • 分析了基于数据及时性的关键农业食品可追溯性链接和建议的要求.
  • 将过期的农业食品可追溯性数据卸载到IPFS以减少区块链存储压力.

主要成果:

  • 拟议的架构在36个月后,与传统系统相比,只能达到52.38%的存储容量.
  • 当根据规定删除过期数据时,存储容量从线性降低到恒定水平.
  • 在以太坊私有链上评估正确性,抗碰撞性和存储性能.

结论:

  • 这种LAP链架构有效地降低了基于BCT的AFSCTS的存储压力.
  • 这种方法确保了数据的问责制,并有可能提高农业食品的安全性和质量.
  • 该系统为现代农业食品可追溯性挑战提供了可扩展和高效的解决方案.
