Atomic Swaps and Common-Input Heuristics

In lesson one of this module, we discuss the process of atomic swaps and Hashed Timelock Contracts. Atomic swaps are often used as an obfuscation method to enhance their privacy and conduct trustless means of trading.

This lesson also covers Common-Input Heuristics, which is the clustering (deanonymizing and grouping) of addresses and transactions.

Main Topics: Atomic Swaps, HTLC’s (Hashed Timelock Contracts), Common-Input Heuristics, and some technical basics for Bitcoin.

Coinjoin, Wasabi, Schnnor, and Dandelion

In lesson two, we discuss what coinjoin is, how it is beneficial to users of cryptocurrency, and the major service providers of coinjoin. We also examine three Bitcoin Improvement Protocols (BIPs), which will enhance privacy, accelerate transaction computation speed, and save space on the blockchain if successfully implemented.

We also cover The Dandelion Protocol which further obfuscates the tracing of IP addresses via nodes and thwarts the efforts of cryptocurrency deanonymization techniques.

Main Topics: Coinjoin, Major Coinjoin Servicers (Wasabi, Samurai Wallet), Bitcoin Improvement Protocols Taproot and Schnoor, The Dandelion Protocol

Tether, Omni Layer, and the Lightning Network

In lesson three of this module, we cover the Omni Layer and its uses in today’s world. We also look at how Tether and other token asset transactions on the Omni Blockchain Explorer can be investigated and what clues an investigator should keep in mind.

This lesson also covers the Lightning Network and the benefits and drawbacks of Sidechains and Payment Channels.

Main Topics: Omni Layer, Tether, Omni Blockchain Explorer, Lightning Network, Sidechains, and Payment channels

The five methods include First in, First Out (FIFO), Last In, First Out (LIFO), the Poison Method, the Haircut Method, and the Taint In, Highest Out (TIHO) method.
