Industry sources fear there may be as few as 10 energy suppliers left by the end of the year, down from 70 in January.crypto-js aes 加解密Opposition politicians have expressed concern, with Labour's shadow economic secretary to the Treasury, Pat McFadden, describing the problems as a crisis that "should have been foreseen".
Liberal Democrat leader Ed Davey, a former energy secretary, has said it is proof that the UK government's energy policy has been "lamentable".And speaking on BBC Two's Newsnight programme on Monday, the former Brexit Secretary, David Davis, warned there was a risk of a "cost of living crisis" for new Tory voters such as "the plumber, the bricklayer, the lorry driver".He said his advice to Chancellor Rishi Sunak would be: "You think hard about the ordinary family's take-home pay and what they have to buy with it, because that will be a dictator of how people feel going in to the new year."Stacey Stothard followed all the advice. Aware that energy prices were rising, she shopped around to find a decent fixed deal for her gas and electricity.She saved £300 - or so she thought.
Her new energy supplier went bust and now she will be switched automatically to another one, and she is facing much higher bills, potentially amounting to hundreds of pounds more a year."It is just like watching the meter go up and up," she says. "I did the right thing - not going for the cheapest deal, but choosing a company with a decent customer service record."The SHA-256 algorithm takes inputs from users and encrypts them to produce a unique output that is difficult to predict. Solana takes the output of a transaction and uses it as the input for the next hash. The order of the transactions is now inbuilt into the incoming hashed output. This is different from how the Bitcoin blockchain operates.
The Solana PoH hashing process creates a long, unbroken chain of hashed transactions. This is designed to create a clear and verifiable order of transactions so that when a validator adds to a block, they don’t need to use a conventional timestamp.Blocks on the Bitcoin blockchain are large and unorganized. Each BTC miner adds the time and date to the block they mine based on their local time. Other nodes in the network then have to verify that the timestamp provided by the miner is valid because it may be false or differ from the time reported by other miners. This is time-consuming.By ordering transactions into a chain of hashes, however, Solana validators are able to process and transmit less information per block. Having that hashed version of the latest state of transactions constantly recorded greatly reduces the time to confirm each block on the Solana chain. Transactions on Solana are verifiably ordered without all nodes needing to agree simultaneously. This is a key reason why it is so quick.Proof-of-History combines with other features of Solana to optimize and speed up throughput. For example, TowerBFT is Solana’s version of a Byzantine fault-tolerant Proof-of-Stake consensus model that uses the cryptographic clock enabled by PoH to speed up blockchain consensus by reducing messaging overhead and transaction latency. Selecting the next Proof-of-Stake node to validate a block of transactions becomes faster because nodes need less time to verify the order of transactions.
In a blog post from July 2019, Anatoly Yakovenko describes eight key innovations that make Solana “the First Web-Scale Blockchain”. Aside from Proof-of-History and Tower BFT (more on those later), the six other key innovations are:Turbine — a block propagation protocol
Gulf Stream — a mempool-less transaction forwarding protocolSealevel — parallel smart contracts run-timePipelining — a transaction processing unit for validation optimizationCloudbreak — a horizontally-scaled accounts database
Archivers — distributed ledger storageWhen combined, these features allow Solana to offer transactions and fees at a speed and cost much lower than other smart contract platforms.SOL staking for yield farmingAs mentioned, Solana is a proof-of-stake blockchain with a focus on delegations. This means that anyone who holds SOL tokens can choose to delegate some of their SOL to one or more validators, who process transactions and run the network. SOL users need to stake or lock up their tokens with a validator.
In mid-June Staking Rewards.com listed Solana as the fourth-largest blockchain by value of assets staked - with US$13,475,960,413 staked. The Cardano, Polkadot, and Ethereum blockchains were all ahead of it at the time. Today, Solana is the largest staked network with US$67,075,392,728 staked on it. This is an almost 400% rise in value staked.The current estimated interest rate for SOL holders who delegate their tokens to a validator is 6.4%. Adjusted for the inflation rate of network supply, however, this interest rate drops to 0.95%. According to Staking Rewards, validators running a Solana Node will earn an interest rate of 7.05% but once adjusted for network supply inflation this drops to 1.95%.
Users can delegate their tokens to a staking pool that will, for a fee, participate in the network’s Proof-of-Stake consensus on behalf of the delegator. Or run a node themselves and directly participate in consensus. Staking rewards.com describes the complexity of Delegating SOL to a staking pool as ‘easy’. Wallets like SOLflare.com allow for allocation to a pool within minutes and rewards are automatically compounded. It describes the complexity of running your own Solana validator node as ‘professional’. There are very high hardware requirements, validators also need to put up to 1.1 SOL per day to pay for vote transactions.The percentage of available SOL being staked is 76.6%. There has been a sharp increase in new stakers to the network in the last 30 days. Indicating a shift in sentiment of SOL holders with deeper commitment to lock in held assets to the network. Staking to the Solana network requires locking up assets for at least 5 days.
Brave New Coin lead analyst Josh Olszewicz analyzed the Solana network and the price of the SOL token on September 8th. Josh backs the blockchain’s staking mechanism and burgeoning smart contract as value lockers and funnels to drive new entrants into Solana and SOL. On the technical side, Josh describes current volumes on Solana as “insane.” He says that while bullish continuation is possible it is more based on hope than it was a month ago. It would require more spikes in volume and euphoria from bulls to support further price all time highs.Solana is a new blockchain platform network that has found product market fit in 2021. Solana has attracted headlines after news that Solana Labs, the development team that manages the Solana chain technology, had raised US$314 million of new funding. The money will be used to develop technology in the Decentralized Finance (DeFi) space. The funding round was led by prominent Silicon Valley VC firm Andreessen Horowitz, and crypto-specific hedge fund Polychain Capital.Discussing the project after the raise, Alameda Research CEO and long term Solana backer Sam Bankman-Fried said the project has “the most ambitious tech road map of any blockchain, and they’ve been making impressive progress on it. It’s a blockchain that has the potential to support a DeFi ecosystem with world-scale activity.”Despite being attached to the 6th largest asset in crypto, Solana is a new project that has only shown glimpses of what it is really capable of. Its Dapp ecosystem is nascent and most of what has been built is closely based on an Ethereum blueprint.These somewhat unoriginal Dapps, however, are fast, cheap, and easy to use. They offer some of the best UX in crypto. Solana also has one of the best experiences for stakers in the space. This is indicated by the increasing commitment of SOL holders to stake in the network.The network remains relatively decentralized, it has big-name VC backers and influencers endorsing it as the future and it continues to attract developers to build on it. It ticks all the boxes and the only question now is if this ongoing momentum can be maintained.
A curated weekly summary of forward-focused crypto news that matters. This week, Ethereum hovers around US$4000 after its first deflationary day, Bitcoin's appeal as a macro asset grows, and Solana continues its epic surge, climbing up the top 10 digital asset chart.
It was a bullish week of trading in the digital asset markets with a surging Ethereum leading to strong gains throughout the week. Ethereum (ETH) ended the week up an impressive 22% and is poised to challenge the key US$4000 price level. Bitcoin (BTC) ended the week up ~6% having broken the key US$50,000 price level. Alpha performers amongst large cap assets included Solana (SOL), and Filecoin (FIL), which rose ~46% and ~60% respectively.Ethereum had its first ever deflationary day on September 3rd. This means that more Ethereum was burnt from transaction fees than was earned by miners. On September 3rd over 13,814 ETH worth ~US$55 million was burnt, a new record, compared to the 12932 ETH that was minted.
The burning or removal of ETH out of circulation is a new feature of the network. It was introduced on August 5th, as part of EIP1559, which was implemented during the non-backward compatible London hard fork. ETH has been on a sustained rally ever since, rising by ~58%. EIP1559 also introduced a base transaction fee burn mechanism. The base fee required for all Ethereum network transactions is now burnt, a design choice to prevent miner collusion.The burn feature means that ETH now has a Bitcoin halving-esque supply constriction mechanism. The yearly inflation (money supply) growth rate is set to reduce significantly and gives ETH more appeal as a buy and hold asset.
The design of the burn mechanism means that as the transaction demand of Ethereum increases, more ETH is taken out of circulation. So if demand increases, the new supply decreases, and these two tailwinds should push the price of ETH higher. The biggest driver of demand to use Ethereum in the last week has been the booming Non-Fungible-Token (NFT) market. OpenSea, the biggest marketplace for Ethereum-based NFTs, is the largest user of gas on the network. Other NFT projects driving gas usage include Trash Pandas and the Lucky Buddha Club.Bitcoin had a strong Sunday on the back of global stagflation concerns. The market is bullish on macro hedge investments and with large outflows of US government debt now occurring, money is flowing into risk assets. Tech stocks and Bitcoin have both surged as a result.Stagflation occurs when growth is slow but inflation is high. In this environment, even aggressive monetary policy can be ineffective in stimulating economic activity. Last month saw the U.S. create the fewest new jobs in seven months. Job creation in the United States is drying up due to a new rise in COVID19 infections. Sectors that have been especially hard hit include leisure and hospitality.This macro-environment appears ideal for Bitcoin, and the wider crypto-asset space, to achieve further gains as more investors search for yield and hedging opportunities.

Crypto news for the week aheadSeptember 7th - Basic Attention Token Community call
A community call will be held this week for the ever-popular BAT token and Brave browser communities. The number of Brave users has just crossed the 36 million mark and the platform now has over 1.2 million users. The price of BAT is up ~18% in the last 7 days.September 12th - Alonzo hard fork
The third-largest asset in crypto is set to implement smart contracts to its mainnet as part of the upcoming Alonzo hard fork. After a four-year wait, developers will finally be able to build dapps and programs on the chain. There are, however, concerns around the efficacy of Cardano’s UTXO model. A testnet AMM designed for high throughput dapps struggled to handle transaction demand. Cardano (ADA) is up ~2% and is up ~107% in the last 30 days.Top 10 Crypto SummaryIt was a bumper week for large-cap assets on the Brave New Coin market cap table with many assets enjoying double-digit gains. Solana rose another spot on the table, from 7th to 8th, and is up ~46% in the last seven days. Pyth went live on Solana a week ago. Pyth Network is a decentralized, cross-chain data oracle that is set to make dapp building easier by creating a funnel for real-time market data to DeFi applications.Bitcoin surged past the US$51,000 price level this week and looks primed to rise higher. Glassnode reports that long term holders continue to accumulate BTC. At present, the majority of on-chain volume represents coins that have moved in the last month. That means older coins are staying put with the hands of long-term investors. Glassnode suggests that this is a bullish indicator.
What's a CryptoPunk and why are CryptoPunks so valuable? We look at the trends driving the booming NFT market - and ask what happens next?Non-Fungible-Tokens are crypto’s hottest investment space so far in 2021, with millions in trades and rare works like Beeple’s EVERYDAYS: THE FIRST 5000 DAYS, selling at a Christie’s auction in March for $69,346,250 - setting the record for the most expensive NFT ever sold.
As the NFT market continues to explode, the nascent sector was given further legitimacy this week with an announcement that CryptoPunks are going Hollywood.The Hollywood Reporter reports that the CryptoPunks NFT project has signed with United Talent Agency for representation across film, TV, video games, publishing, and licensing. The UTA will also represent Meebits and Autoglyphs, two other NFT projects created by Larva Labs.
It means that CryptoPunks will be the first example of blockchain-based IP to make the jump to more traditional forms of content.The news follows last week's announcement that Visa had purchased a CryptoPunk NFT.
