The Digital Tulip Bulb Mania

A community that questions the mania behind bitcoin prices. We are skeptical that cyrptocurrencies are a safe or enduring investment. We want to invoke reason into the discussion about bitcoin and explore rational ways to evaluate any value it may have. Generally, we view bitcoin as a speculative bubble.

Komodo and Bitcoin's blockchain security question

Hi, I have just recently learned about Komodo am doing lots of research on it but I am curious as to how Komodo taps into Bitcoin's blockchain to enhance its security. Can anyone help me understand? Thanks!

Decentralized identities with Bitcoin and ION layer 2

Bitcoin blockchain is by far the most secure blockchain. The blockchain can play the role of a trustless decentralized timestamp server and combined with layer 2 networks it will help to solve a thirty years problem: decentralized identities.
Let's say you want to talk to Bob that you don't meet and probably never will (Snowden as true extreme case, or any store website). You ask him online a public key to communicate privatly with him through encryption. You received a public key, how can you be sure that this public key is really Bob's public key ? Can you trust this public key ? The answer is no because you can't trust what you see online (what if youBob's computesocial media account/private key are compromise ?).
There are two solutions: * meet Bob personnaly so that he gives you a public key * get his public key with the signature of someone you trust enough when he say he got Bob's key and check the ownership more or less physically (Certificate Authorities)
The first is implemented in the "web of trust" settings of PGP. "Web of trust" scale very badly, people must organize key signing party's to sign public keys with their master key. When surfing on the web, we need to trust the signature of Certificate Authorities to be sure to be on the good website. They are central point of censorship and they can be maliciously by signing the public key for an identity that don't own the private key.
But our good blockchain can save the day. Let say you found all the public key that pretend to be owned by Bob. There can be several public key owned by Bob but there is one you are sure is a good one: the one that was the first created. Indeed, you may assume that no one knows the existence of Bob before he was asked for a public key the first time to get an account on any website. So what we need is a trustless decentralized way for Bob to prove that he created one public key before any other public key that can associated with him. And you can already do that on Bitcoin blockchain with an OP_RETURN transaction or here for free !
Once this is done Bob can now create an identity. It is an object (a kind json file) containing the anchored public key of Bob at the root where he can add stuff by sending an operation message with a signature. Each file's operation are anchored in the blockchain for time stamping. This timestamping allows to prove that the last state of the object was made before a certain date. But Bob also add the hash of the previous operation in the message so that we keep the order of operation. This build a kind of separate blockchain stored in a decentralized broadcast network in layer 2 of Bitcoin. This is what ION network of Microsoft does as explained here.
Bob can add to the object several public key for recovery in case he loses the master private key or other stuff where he is susceptible to be asked for his approuval, he can also revoke keys. The applications are wonderfull :
It is clear that Bitcoin's blockchain security will deeply change internet !

[ Bitcoin ] Could blockchain be used to secure voting?

[ 🔴 DELETED 🔴 ] Topic originally posted in Bitcoin by foxy-agent [link]
Hi everyone, I recently started reading about Bitcoin and have become really intrigued by the concept of the blockchain to authenticate transactions as a master ledger. While this is obviously great for financial records, my brain made a connection outside the box for a use case: voting. I like participating in my democracy, and assume others do too, but standing in line at the polls, risking your health, getting time off from work or finding a ride to a voting location an demotivate you from participating. I wish it were easier, like online banking, but after so many news stories of companies getting hacked and losing user data it’s really scary to think that so much information & power could be manipulated by just one system. For the moment, a diversified node system seems to be the most secure.
But I would love to see a day come when voting is as easy as downloading an app to my phone and logging a vote. Authentication for log-in could be based on matching a SSN to some kind of 2-factor authentication info (USPS mailer card with PIN?). But even with a way to verify one real person with one vote, a centralized system is a major target for hacking.
So my question is, could blockchain be used to authenticate voter roles? I believe it could, although I see there is a limit to the number of transactions per block, which might limit the number of votes that could be recorded in a given time frame. One solution might be a very large block, since the chain would not be that long, but another solution to handle the throughput of millions of votes cast in one day could be several smaller chains that tie into a larger chain, like a reverse fork? Each state (or county) run a blockchain and then send their independent results to a larger blockchain?
For example, several cities in a county could collect votes from 12am to 11:59pm, and then the balance of their transactions (the votes) could be submitted to county or a state’s ledger, and then the state could submit their ledger to the national ledger, and it would all be verified with blockchain.
Anyway, would really appreciate any input to this idea.
