Proof of stake (PoS) is a type of consensus mechanisms by which a cryptocurrency blockchain network achieves distributed consensus. In PoS-based cryptocurrencies the creator of the next block is chosen via various combinations of random selection and wealth or age (i.e., the stake).

PoS vs PoW
A consensus mechanism can be structured in a number of ways. PoS and PoW (proof-of-work) are the two best known and in the context of cryptocurrencies also most commonly used. Incentives differ between the two systems of block generation. The algorithm of PoW-based cryptocurrencies such as bitcoin uses mining; that is, the solving of computationally intensive puzzles to validate transactions and create new blocks. The reward of solving the puzzles in the form of that cryptocurrency is the incentive to participate in the network. The PoW mechanism requires a vast amount of computing resources, which consume a significant amount of electricity. With PoS there is no need for 'hard Work'. Relative to the stake, the owner can participate in validating the next block and earn the incentive.
Block selection variants
Proof of stake must have a way of defining the next valid block in any blockchain. Selection by account balance would result in (undesirable) centralization, as the single richest member would have a permanent advantage. Instead, several different methods of selection have been devised.
Coin age-based selection
Peercoin's proof-of-stake system combines randomization with the concept of "coin age", a number derived from the product of the number of coins multiplied by the number of days the coins have been held.
Coins that have been unspent for at least 30 days begin competing for the next block. Older and larger sets of coins have a greater probability of signing the next block. However, once a stake of coins has been used to sign a block, it must start over with zero "coin age" and thus wait at least 30 more days before signing another block. Also, the probability of finding the next block reaches a maximum after 90 days in order to prevent very old or very large collections of stakes from dominating the blockchain.[non-primary source needed]
This process secures the network and gradually produces new coins over time without consuming significant computational power.[unreliable source?]
Criticism
Some authors[non-primary source needed][non-primary source needed] argue that proof of stake is not an ideal option for a distributed consensus protocol. One issue that can arise is the "nothing-at-stake" problem, wherein block generators have nothing to lose by voting for multiple blockchain histories, thereby preventing consensus from being achieved. Because unlike in proof-of-work systems, there is little cost to working on several chains. Some cryptocurrencies are vulnerable to Fake Stake attacks, where an attacker uses no or very little stake to crash an affected node.
Notable attempts to solve these problems include:
Peercoin is the first cryptocurrency that applied the concept of PoS.[citation needed] In its early stages, it used centrally broadcast checkpoints signed under the developer's private key. No blockchain reorganization was allowed deeper than the last known checkpoints. Checkpoints are opt-in as of v0.6 and are not enforced now that the network has reached a suitable level of distribution.[citation needed]
Ethereum's suggested Slasher protocol allows users to "punish" the cheater who forges on top of more than one blockchain branch.[non-primary source needed] This proposal assumes that one must double-sign to create a fork and that one can be punished for creating a fork while not having stake. However, Slasher was never adopted; Ethereum developers concluded proof of stake is "non-trivial", opting instead to adopt a proof-of-work algorithm named Ethash.[non-primary source needed]
Nxt's protocol only allows reorganization of the last 720 blocks.[non-primary source needed] However, this merely rescales the problem: a client may follow a fork of 721 blocks, regardless of whether it is the tallest blockchain, thereby preventing consensus.

Because of exceptional security mechanisms like this, Monero has developed something of an unsavory reputation—it has been linked to criminal operations around the world. While this is a prime candidate for making criminal transactions anonymously, the privacy inherent in Monero is also helpful to dissidents of oppressive regimes around the world. As of January 2021, Monero had a market cap of $2.8 billion and a per-token value of $158.37.What is Bitcoin Mining?почему bitcoin 999 bitcoin monero биржи top cryptocurrency bitcoin ico курс ethereum ethereum torrent конвектор bitcoin

новости ethereum bitcoin etf bitcoin инвестиции расчет bitcoin ethereum github bitcoin цена алгоритм bitcoin 'The nature of Bitcoin is such that once version 0.1 was released, the core design was set in stone for the rest of its lifetime. Because of that, I wanted to design it to support every possible transaction type I could think of. The problem was, each thing required special support code and data fields whether it was used or not, and only covered one special case at a time. It would have been an explosion of special cases. The solution was script, which generalizes the problem so transacting parties can describe their transaction as a predicate that the node network evaluates. The nodes only need to understand the transaction to the extent of evaluating whether the sender's conditions are met... Future versions can add templates for more transaction types and nodes running that version or higher will be able to receive them... The design supports a tremendous variety of possible transaction types that I designed years ago. Escrow transactions, bonded contracts, third party arbitration, multi-party signature, etc. If Bitcoin catches on in a big way, these are things we'll want to explore in the future, but they all had to be designed at the beginning to make sure they would be possible later.'bitcoin escrow bitcoin download bitcoin node

captcha bitcoin обменники bitcoin bitcoin 99 bitcoin addnode There are various ways to secure a bitcoin wallet, the popular ones being encryption, backup, multisig and cold storage; none is infallible though. The first way is to encrypt your wallet by using a strong password. The second way is to make a backup of the wallet. Even a computer malfunction can result in a loss of bitcoins, let alone hacking. Multisig is another method is to protect bitcoins. It involves creating a multi-signature transaction system under which more people (usually at least 2 or 3) need to approve the funds being released.uk bitcoin bitcoin иконка rx580 monero How does Bitcoin compare to gold? After all, some people still consider gold to be the real money. It is certainly the gold standard to which other currencies must be compared. We begin with the World Gold Council's figures. They estimated that about 190,000 tonnes of gold had been mined throughout history as of the end of 2017.3 An average of around 2,500 tonnes are mined per year, so we can safely estimate around 195,000 tonnes of gold in existence at the end of 2019. There are 32,150.7 troy ounces of gold in one tonne, and the price of gold per ounce was $1,615.50.4 So, we can estimate the total value of all gold as:goldsday bitcoin bag bitcoin nicehash bitcoin

Note that the state is not encoded in the block in any way; it is purely an abstraction to be remembered by the validating node and can only be (securely) computed for any block by starting from the genesis state and sequentially applying every transaction in every block. Additionally, note that the order in which the miner includes transactions into the block matters; if there are two transactions A and B in a block such that B spends a UTXO created by A, then the block will be valid if A comes before B but not otherwise.bitcoin блок
