Questions tagged [alternatives]

Questions about alternative blockchains are off topic unless they are applicable to Bitcoin.

This is the tag for all questions concerning alternatives to Bitcoin (altcoins). This includes forks of the Bitcoin Core software with possible modifications and / or a new genesis block (such as litecoin) and also blockchain-based cryptocurrencies which were created using an entirely new codebase. It also covers cryptocurrencies which were created by hard-forking the bitcoin blockchain (eg a deliberate, non-backwards-compatible change to the consensus rules).

Note: questions related to a project that has its own SE site should be moved there eg:

Is there a way to set up proof-of-work systems so they would be even more useful?

One of the arguments made against Bitcoin's design choices is that it wastes resources authenticating transactions. In particular, finding small hashes is completely useless for the world. Are there approaches (or other crypto-currencies) that use…

Does flattr complement or compete with bitcoin?

Will forks and alternative block chains cause hyper-inflation of decentralized digital money?

Great effort has been put into Bitcoin's concept of money supply and that there will never be more than 21 million units. However, it's relatively easy to fork it and create alternate block chains. SolidCoin, IXCoin, IOCoin etc are much less worth,…

Has anyone attempted to make a working voting system using a bitcoin based system?

It occurred to me the other day that the difficult problem of electronic voting could possibly be solved quite nicely using a bitcoin system. I believe it's transparent enough to be trusted. I found a few threads discussing this already. Has any…

Why do we need alternatives to Bitcoin?

I don't understand why people need to create alternatives to Bitcoin such as litecoin. Why were these created? What's the point? You can't answer those questions using the same arguments for why Bitcoin was created.

What is the "zeitgeist attack"? Does it affect all blockchain technologies?

What exactly is this attack? It would be nice to have a good explanation of how it works and which chains can be effected by this. Does it apply to the bitcoin main chain, or only the newer and smaller alternative chains?

What keeps a dominant Bitcoin client vendor with the majority of the market share from unilaterally changing the protocol?

I've been asking this in the comments, but I'll be more direct. If a third-party Bitcoin client, say "iBitcoin" (for example), becomes the dominant client by acquiring most of the market share, what would keep the vendor from unilaterally changing…

For me, scripts are one of the most interesting features of Bitcoin. They provide possibilities which have no equivalent in classical currencies. However, the wiki states It is purposefully not Turing-complete, with no loops. What's the rationale…
