Key points
- Variant PoW blockchains constitute over 90% of the cryptocurrency market capitalization.
- Existing security analyses primarily focus on Bitcoin's PoW.
- Variant PoW blockchains often use different consensus and network parameters.
- The applicability of Bitcoin's security guarantees to variant PoW blockchains is not well-established.

Abstract
Proof of Work (PoW) powered blockchains currently account for more than 90% of the total market capitalization of existing digital cryptocurrencies. Although the security provisions of Bitcoin have been thoroughly analysed, the security guarantees of variant (forked) PoW blockchains (which were instantiated with different parameters) have not received much attention in the literature. This opens the question whether existing security analysis of Bitcoin's PoW applies to other implementations which have been instantiated with different consensus and/or network parameters.
