If you do that, crypto it means that for the miner to hide any piece of the block, they have to hide half of the block. It's no longer 100% availability problem, now it's a 50% availability problem. A client can randomly sample different pieces of the block. Using this, you can build a sampling based availability scheme. Clients would then gossip pieces to full nodes for recovery of the data. You might require a miner to commit with the merkle root of the erasure coded version of the block data. Because if they hide just one piece here, then that piece can be recovered from the rest of the pieces. If you assume the miner has hidden 50% of the block or slightly more because they don't want the block data to be recovered, then there's a chance that the client will land on an unavailable piece, then the block is rejected. However, if they hide a bit more than half of the data, then the block cannot be recovered.
60% after 3 samplings; 99% after 15 samplings. What is the probability of a client landing on at least one of the available piece if the miner has hidden 25% of the square (if sampling without replacement)? But you could also have a high probability if you do more samplings. On average, miners would have to do 100x more PoW in order to generate that invalid block. After 15 samplings, there's only a 1% chance that the miner can fool a user into thinking that a block is available when it's unavailable.
Bloomberg News reported that the Biden administration is preparing to release an initial government-wide strategy for digital assets as soon as next month and will ask federal agencies to assessing the risks and opportunities they pose. And the case for further caution was reinforced on Friday.
"Margin positions being liquidated caused a wave of additional sell pressure, as assets that had been held as collateral were forcibly sold to pay for margin loans," said Hayden Hughes, chief executive officer at Alpha Impact in Singapore.
With the Federal Reserve’s intentions on reining in inflation rocking both cryptocurrencies and stocks, a dominant theme has emerged in the digital-asset space: cryptos have moved in the same way as equities and many other risk assets.
While there have been much larger percentage drawdowns for both Bitcoin and the aggregate market, this marks the second-largest ever decline in dollar terms for both, according to Bespoke Investment Group. Bitcoin
’s decline from its peak has wiped out more than $600 billion in market value, and over $1 trillion has been lost from the aggregate crypto market.
В настоящее время в криптовалютном сообществе наиболее оптимальным решением видят Optimistic Rollups. пока не будет запущен Ethereum 2.0. Так считает и сам Виталик Бутерин, но похоже в контексте «перебиться», т.е.
To solve the scalability issues the developers are working on several solutions. But the Ethereum 2.0 that is said to solve the scalability issues is in experimental stage and it will likely take years to get fully implemented.

Also we’ve explained how to easily connect your Metamask or web3 wallet to any EVM network. Here in this post we’ve made a list of EVM blockchains. That is the list of all Ethereum based blockchains or Ethereum like networks. Discover Ethereum’s most promising competitors and popular alternatives with EVM compatibility. Looking for Ethereum alternatives that are compatible with the EVM (Ethereum Virtual Machine)?
Other digital assets also slid, with Ethereum down 12%. Bitcoin
fell as low as $34,042.78 Saturday, a drop of 7.2%, before paring most of those losses. Solana and Cardano each fell at least 17%, according to Coinbase.
Before adding the network; verify the chain details and make sure you are connected to the correct chain. Since it is an open source tool anybody can add any EVM network to the list. You’ll find more new EVM networks getting added to the list.
Our computations are also efficient, taking a few milliseconds. It's quite efficient in the space, a state fraud proof would be quite small. I'll take questions now, thank you. The link to the full paper is here.
#SilverSqueeze may be out of the headlines, but investors are still stacking. The actual number of bars underpinning the enormous volume of paper silver trading has been in steep decline since early 2021.
The problem with this is what if the miner only sends the blockheaders to the SPV client but doesn't actually publish the transaction data? In that case, it would be impossible for the full node to generate a fraud proof that the transactions are invalid because they don't know what the transactions are. With a fraud proof system, if a full node downloads a block and detects an invalid transaction, they could in theory send a proof to that SPV node that the block has an invalid transaction and then the SPV node could verify the proof and reject that block permanently. You can end up in a situation where SPV nodes are accepting invalid blocks because nobody can generate a fraud proof for them.
