EIP-155 Replay Attack Protection Now Available on the Callisto Network for use with Ledger Nano S

Written by Michael Ira Krufky

As described in Wikipedia, a replay attack (also known as a playback attack) is a "form of network attack in which a valid data transmission is maliciously or fraudulently repeated or delayed. This is carried out either by the originator or by an adversary who intercepts the data and re-transmits it, possibly as part of a masquerade attack by IP packet substitution. This is one of the lower tier versions of a 'man in the middle attack.'"

Storing and Staking Akroma Safely using the Ledger Nano S Hardware Wallet

You've been mining and / or trading AKA for some time, and you've finally saved up enough to stake a masternode. It's time to get your wallet ready to send yourself a verification transaction.

After enough searching, you've finally found that JSON wallet on your computer. Time to send that transaction... WHAT?!? A PASSWORD?!? You don't recall setting a password for this wallet! Isn't the whole public / private key thing enough? No. You also have a password, and you just can't remember it.

Does this sound like you? It sounds like me. That's what happened to my first masternode. Oh well. I eventually remembered that password, but I don't want to find myself in that situation ever again.

I don't like the idea of storing cryptocurrency in JSON wallets on my dev boxes. They could get hacked. Even if they don't get hacked, they have passwords that could be forgotten. Instead, I use a hardware wallet to store and stake al

Staking a Pirl Masternode from a Hardware Wallet using Pirl's Web Wallet

Overview

This guide uses the one-click-masternode setup feature. This is an optional feature for those that wish to have a more hands-off experience with the setup of their masternode. This Poseidon feature automatically configures your CentOS7 linux server to be a Pirl Masternode. Updates will be applied automatically. All you have to do is monitor your server to ensure it stays operational. This is as simple as rebooting the server, should it go offline. Manual installation instructions are also provided for those that want a bit more control of the system.

Prerequisites

• a VPS with minimum 4GB RAM and enough storage to run the masternode (minimum 20GB, recommended 60GB)
• a JSON wallet address or a hardware wallet compatible with https://wallet.pirl.io. You may import your JSON wallet from Nautilus if you so choose.
