Companies and organizations typically have databases that hold user information like emails, names and addresses. The computers that hold databases usually exist in one singular location and are operated by one person or a small group, known as administrators. A blockchain is a type of database, but instead of its information being in one central location and under the supervision and control of a few, it is dispersed among many individuals and locations.
This way, if one computer goes down there are plenty of others keeping the data and network alive. These individuals must find a way to agree on the correct set of data so that all of their versions of data match. To form this consensus some sort of mechanism is necessary. There are various types of consensus mechanisms that blockchains employ to ensure that the data in the case of a cryptocurrency this data is transactions stays consistent across all the nodes individual computers in the system.
Moving to Proof-of-Stake The original mechanism used by blockchains is proof-of-work. PoW requires computers to compete against each other to process transactions and get rewards. This process is highly energy-intensive and also time-consuming. For this reason, some newer cryptocurrencies have opted to go another route — proof-of-stake. Ethereum's upgrade to version 2. With PoS, consensus is reached by using an algorithm that chooses a node to win a block of transactions, rather than the nodes competing to win the block by using large amounts of power.
When a node is chosen it forges the next block of transactions in the chain. With PoS, these nodes are generally referred to as "stake pools. In other words, the more coins a stake pool holds the more likely it is to be chosen to forge a block and get rewards. To ensure that the wealthiest pools do not always win, other criteria, like the amount of time coins have been staked, can factor into the selection process.
Holders of the coin can "stake" their holdings to a stake pool and when a pool node is selected to forge a block the reward it receives is distributed among the individual stakers. Some PoS blockchains have added a degree of randomization into the process so that older and larger stakes do not always win. So, in PoS, miners are replaced with stake pools where people stake their coins. Individuals can "stake," or place their coins with various stake pools, just the same as miners joining a mining pool to earn more rewards.
It's important to first understand that staking your ETH will lock them in place until the full release of Ethereum 2. Your Ether will of course earn staking rewards while it is locked, but stakers can not remove their ETH from the stake pool. Staking to Ethereum's testnet through a stake pool is a bit tricky and comes with a good deal of risk. For that reason, it's best left for the more technically advanced.
For those that wish to take an easier more hands-off approach, staking on an exchange is probably best. Some of the exchanges that allow Ethereum holders to stake right now include Kraken, Coinbase, Binance and more. How It Scales Ethereum 2.
This is a common technique among a number of newer PoS cryptocurrencies as it allows them to scale without major sacrifices to security and decentralization. Sharding is a way to partition a database into smaller pieces that are more manageable.
With a PoW blockchain, most nodes, or computers in the network, have an entire copy of the history of transactions. This entire history can take up a lot of space, especially for older cryptocurrencies with a long history of transactions. With sharding, the blockchain is cut up into parallel sections, and nodes are assigned to one section instead of having to hold the entirety of the chain's data.
This allows more transactions to be processed simultaneously, greatly increasing throughput and transaction speed. Should ETH 2. Ethereum has a massive decentralized financial ecosystem, but most of it is nearly unusable as it is too slow and congested. This congestion can cause transaction fees to be larger than the amount of money the user is trying to move in the first place.
In Ethereum's current state, only those with larger holdings can make use of the benefits of its ecosystem. This makes sending a few dollars or trading small amounts of money impossible. The fees to make transactions are so high because they are controlled by miners, creating a rather large conflict of interest. Check out the consensus clients previously known as 'Eth2' clients If you're more technical, you can help catch bugs in the new clients.
View the bug bounty program You can also weigh in on the technical discussions with Ethereum researchers at ethresear. Visit ethresear. More The term 'Eth2' itself is being phased out, as it does not represent a single upgrade or new network. It is more accurately a set of multiple upgrades that all do their part to make Ethereum more scalable, secure, and sustainable. The network you know and love will simply be referred to as Ethereum.
We're reluctant to talk too much in terms of a technical roadmap because this is software: things can change. We think it's easier to understand what's happening when you read about the outcomes. View the upgrades But if you've followed the discussions, here's how the upgrades fit into technical roadmaps, and a bit on how they're changing.
Phase 0 described the work to get the Beacon Chain live. Phase 1 originally focused on implementing the shard chains, but prioritization shifted to The Merge, which shipped on September 15, Phase 1. However, as rollup technology progressed, the Ethereum community expedited the transition away from proof-of-work instead. More on proof of stake The plans around Phase 2 have been a point of intense research and discussion. With The Merge behind us, and the advancements in layer 2 solutions, goals have shifted to provide a more simplified form of data sharding to maximize rollup efficiency.
Current layer 2s enable the ability to scale transaction execution, and sharding will allow for storage of proofs for this data on layer 1 in a cheap and scalable manner.

There are no middlemen involved or country-specific servers, so silencing a particular user is also impossible. Such contracts are invaluable for industries such as supply chain management, where payments need to be made immediately. These days, smart contracts have also made their way into the collectibles ecosystem. NFTs—or non-fungible tokens—allow anyone to auction real-world or digital assets in exchange for a traceable record of ownership on the Ethereum blockchain.
Since the network is decentralized, transactions on the blockchain need to be validated by the public at large. ETH is simply used to pay for transactions and incentivize these validators. When the network was first released in , there was no real alternative to proof of work—at least not one that was sufficiently tested at scale.
Transactions were occasionally slow to finalize due to the nature of the consensus algorithm, but not overwhelmingly so. However, all of that changed in , when the cryptocurrency market first attained critical mass among mainstream users and investors. As a result, Ethereum went through extended periods of slowdowns —which was only aggravated by the surging popularity of dApp platforms such as CryptoKitties.
Enter ETH 2. Related: Proof of Work vs. Proof of Stake: Cryptocurrency Algorithms Explained Instead of relying on miners to produce new blocks, PoS offers Ethereum holders the opportunity to validate new blocks in exchange for a reward. In this system, users need to stake a minimum of 32 ETH in a deposit contract for the right to verify new transactions.
If the vote is valid as it should always be , the validator is awarded a reward for their honesty. However, if a validator is voted against, a portion of their initial staked ETH will be deducted as a penalty. Since PoS does not involve solving complex cryptographic puzzles, it boasts superior energy efficiency and improved transaction speeds. Besides the move to PoS, Ethereum 2. To ensure compatibility and coordination between shards, Ethereum uses an overarching beacon chain.
This way, users in two separate shards will still be able to transact with each other. When Will ETH 2. As mentioned previously, ETH 2. However, the good news is that its release is already in progress as of mid More specifically, ETH 2. Interested validators may deposit a minimum of 32 ETH to begin staking on the network.
Ethereum has been revolutionary from Day One, and during the ICO craze of it helped expand the crypto ecosystem with entrepreneurs and developers working together to launch the newest, most innovative applications of blockchain technology. Now Binance Smart Chain has taken some market share away from Ethereum thanks to its highly scalable blockchain platform and rapidly growing ecosystem.
The network faces a number of systemic issues around scalability, security and the cost of transactions. That is why the decentralized community that carries Ethereum embarked on a development roadmap to take care of these issues through a series of carefully planned upgrades across four different stages. We are now entering the Serenity stage, the final stretch of a rigorous development plan.
The Ethereum development phases Each stage in the Ethereum development plan introduced more features and fixes to existing problems. Some steps included hard forks that changed functionality in a way that was not backward compatible. March — Homestead block 1,, Removed Canary Contracts which previously gave Ethereum core developers the ability to stop network activities.
It caused a split in the network and the creation of the Ethereum and Ethereum Classic chains. February — Constantinople Improved state channels which provide better support for off-chain transactions. Block rewards were further reduced down to 2 ETH. Smart contracts were allowed to verify each other using just the hash of another contract. This hard fork also included other changes that fixed security issues codenamed Petersburg.
October — Istanbul The next hard fork for Ethereum and the final upgrade before implementing it included more security fixes and incentives to move away from the Proof of Work to Proof of Stake algorithm.
Now, we arrive to the final stretch, Eth 2. The launch for Eth 2. The aim here is to make Ethereum more scalable, faster, and reliable. According to researcher Danny Ryan the main goals under Serenity are: Security: increase participation of validators in total and per unit time.
