Hyperliquid Testnet Validator Infos

Intro

Hello, I'm Jeongseup from Cosmostation.

This document is for sharing some information to prepare hyperliquid network joining as one of validators like us.

As you know, there is an offical docs link: https://github.com/hyperliquid-dex/node , But I wanted to share some personal experiences and insights to newbies like us :)

kmalloc

区块链是分布式的共识账本, 网络中节点众多, 各节点达成共识需要复杂的协议交互(POW 算哈希/POS 投票), 导致系统整体并发能力低下, 无法支持大规模大范围应用(TPS极其低), 拥挤的结果是区块空间异常昂贵, 解决的方法是减少底层 transaction 数量, 把部分计算和存储移到线下.

state channel

bitcoin 上的闪电网络采取的方案, 基本思路是交互双方很多的中间交易是不必全部放到区块链中的, 此时可以通过把钱放到一个合约里面, 线下双方双签维护金额的变化即可, 无需其它无关人士来参与并协调达成共识, 具体例子参考[5].

Understanding the Memory Layout of Linux Executables

Required tools for playing around with memory:

• hexdump
• objdump
• readelf
• xxd
• gcore

kmalloc
