The blockchain itself keeps track of what tokens are held in by each account; the tokens aren’t “in” the wallet or account, but we often talk that way because the metaphor makes sense.In Ethereum- compatible blockchains, a Secret Recovery Phrase (SRP) can generate a number of accounts that approaches infinity. Each one of these accounts has its own keypair, but all of them can be controlled by the SRP.Just like your Reddit account has a username (public) and password (private), so does your Ethereum account; the difference being that you are the custodian of your Ethereum keys, while Reddit holds your login information for their site. For additional security, you can use a password to encrypt your private key which would result in a username (public) and password (private) and password for that password (private + more secure).

Blocks are proposed by proof-of-stake validators, at which point they are shared across the entire peer-to-peer network, where they can easily be independently verified by all other nodes. Consensus rules govern what contents of a block are considered valid, and any invalid blocks are disregarded by the network.

On a more basic level, if we’re coordinating a network running around the world on all kinds of different hardware and software, there are all kinds or problems that can occur that hinder the network’s ability to reach consensus on its current state.

Usually, encrypted private keys are kept within the extension or device they are encrypted by, and they remain out of sight from the user. This is meant to add another layer of security to keep a user’s wallet information safe.By way of example: if the world ‘Apple’ was your private key, then it was encrypted three letters down the alphabet, your new encrypted key would be ‘Dssoh’ .

The computational process involved in committing a series of transactions into a block on the network, known as ‘hashing a block’ , is technically quite simple, and therefore subject to attack. Under PoW, each miner must solve a math problem to find a set, difficult variable in order to be able to propose their block to the network as the next to be ‘mined’ . In effect, the process of hashing each block becomes a competition. This addition of solving for a target increases the difficulty of successfully hashing each block, and consequently the security of the network.For each hashed block, the overall process of hashing will have taken some time and computational effort. Thus, a hashed block is considered Proof of Work, and the miner that successfully hashes the block first receives a reward, in the form of cryptocurrency.

A public key can be derived mathematically from its corresponding private key, but the inverse is not true: it is mathematically impossible to derive a private key from its corresponding public key.

    skos:definition "Total Value Locked, or TVL, is a common expression used in many contexts across the crypto ecosystem, so it’s important to pay attention to the specifics. In general, it refers to how much value, in tokens, has been deposited into something. Most often, it refers to a protocol, which is an application on the blockchain, or a set of protocols. For example, a decentralized token trading platform might have a series of liquidity pools, which are protocols enabling swaps between tokens, and the platform may quote the “TVL” for all the pools combined. Alternatively, if a network uses proof of stake for their consensus mechanism, they may represent the TVL of all the tokens staked into that consensus protocol." ;

With public blockchain networks, data isn’t kept on some centralized server somewhere that could be hacked or changed arbitrarily; anyone can verify the transactions themselves. This is why the term ‘trustless’ was coined: there is no need for trust, although, in a way, the rules and assurances built into the blockchain provide the basis for great er trust between people, because the system is guaranteed to work the same for everyone." ;
