![]() You will trust that the protocol is sound, as well as the implementation of it In this context "power" refers to computational power in the case of PoW and Sybil Attacks, or access to backdoors You will trust that these random people don't have enough "power" to subvert the protocol You will trust a bunch of random people instead of a centralized authority Shifting to P2P essentially just means that: Blockchains are essentially "Paxos, but for a massive peer count, and with some mechanisms that allow it to operate in an adversarial networks", but it is fundamentally still just a consensus algorithm (in Bitcoin's case, one where people "agree" that John Doe has X amount of money). Reputation is another, so are proofs, and so is consensus (which is the most interesting one for the case at hand). There are several mechanisms of trust that exist, authorities are just one of them. It is a dishonest and misleading definition. ![]() It takes a bastardized definition of "trust" to make this statement true, and it's a definition that is most often seen in the wild when used to "sell" blockchain stuff as having technical capabilities they do not, in fact, possess. If the sender of a message did not receive an acknowledgement and wishes to rebroadcast his message, he must update the time and recompute the proof‐of‐work. ![]() I'm also not sure how long a message is kept around the network: say I enter the network and send a message to Alice how long will the message be kept alive in the network by peers so that Alice can still read it when she joins?Įdit: I guess my last concern is simply validated by the fact that the sender can just enter the network again and resend it. However the PoW requirement when I last used this was quite low hence spam was somewhat still present. You don't need complex social trusted networks (like scuttlebutt does) to just enter the network and start relaying messages around - you trust they're not spam since there's PoW behind them. This means that the network should be full of healthy messages that should be human written. Hence for spammers to flood the network would require lots of computing power. Bitmessage is a really cool project because it relies on PoW (proof-of-work) to send messages. ![]()
