With MLB team prop bets you are betting on one team or another, rather than the performance of both teams, such as the spread, points total or money line. As a game gets deeper, teams throw in fire-spitting throwers. Baseball still had plenty of fans, but quickly became marginalized as a betting sport. MLB Betting Today The MLB action comes thick and fast throughout the regular season with each team playing games, totalling 2, total regular-season games. Some things never change.

Utah-based colocation provider C7 Data Centers and Cyxtera were among the providers hit by unpaid bills from cryptocurrency miners. Colocation providers risk being undercut by cryptocurrency miners who seek low cost, and will downsize their operations should bitcoin prices fall. Datacenter suppliers such as Verne Global and Advania, as well as key colocation players including Equinix and Digital Realty, have focused on building a diverse customer base to reduce their exposure to cryptocurrency risk.

Banking and automotive, both sectors that require high-density options similar to cryptocurrency mining, are typically the more stable clientele. Pivot to services As customer needs shift, a few colocation operators are expanding into managed services.

This strategic approach offers new revenue streams, especially for providers that are purely catering to the cryptocurrency niche. CloudHashing, a provider of cloud-based mining services from its facility in Iceland, merged with mining hardware manufacturer HighBitCoin to launch PeerNova in Whether pivoting into IaaS or diversifying their customer base, datacenters are learning sometimes the hard way not to put all their eggs in the bitcoin basket.

Besides, cryptocurrencies such as bitcoin are not actually anonymous, given that individuals and organisations using crypto-wallets still leave a digital footprint. And authorities that legitimately want to track criminals and terrorists will soon crack down on attempts to create cryptocurrencies with complete privacy.

Insofar as CBDCs would crowd out worthless cryptocurrencies, they should be welcomed. Moreover, by transferring payments from private to central banks, a CBDC-based system would be a boon for financial inclusion. Millions of unbanked people would have access to a near-free, efficient payment system through their cell phones. The main problem with CBDCs is that they would disrupt the current fractional-reserve system through which commercial banks create money by lending out more than they hold in liquid deposits.

Banks need deposits in order to make loans and investment decisions. In other words, the fractional-reserve banking system would be replaced by a narrow-banking system administered mostly by the central bank. That would amount to a financial revolution — and one that would yield many benefits. So far, no country has decided to go this route, perhaps because it would entail a radical disintermediation of the private banking sector.

One alternative would be for central banks to lend back to private banks the deposits that moved into CBDCs. Lagarde, for her part, has advocated a third solution: private-public partnerships between central banks and private banks. This is a clever compromise, but some purists will argue that it would not solve the problems of the current fractional-reserve banking system. There would still be a risk of bank runs, maturity mismatches and credit bubbles fuelled by private-bank-created money.

And there would still be a need for deposit insurance and lender-of-last-resort support, which itself creates a moral hazard. In due time, CBDC-based narrow banking and loanable-funds intermediaries could ensure a better and more stable financial system. If the alternatives are a crisis-prone fractional-reserve system and a crypto-dystopia, then we should remain open to the idea.

At a very high level, Bitcoin mining is a system in which all Bitcoin transactions are sent to Bitcoin miners. Miners select one megabyte worth of transactions, bundle them as an input into the SHA function, and attempt to find a specific output the network accepts.

The first miner to find this output and publish the block to the network receives a reward in the form of transaction fees and the creation of new Bitcoin. Bitcoin Mining: A Technical Introduction Mining was introduced as the solution to the double-spend problem. If I have 1 Bitcoin and I send it to Bob, and then try sending that same Bitcoin to Alice, the network ensures that only one transaction will be accepted. It does this through the well-known process called mining.

Before diving into the technical details, its important to understand why mining is necessary to secure the network. As fiat currency exists now, the currency we hold is created and validated by a federal reserve. Because Bitcoin operates under the rigid assumption of decentralization and consensus, no central authority can exist that validates and time-stamps the issuance of that currency and validation of any transactions that occur with that currency.

Satoshi Nakamoto proposed the only known solution at the time to solving this validation problem in a consensus-oriented system. Titled in the Bitcoin whitepaper as proof-of-work, this scheme elegantly justifies that transactions are validated by those who are willing to expend enough physical computational energy and time to do so, while simultaneously introducing an incentive to induce market competition.

This competition enables the property of decentralization to emerge and thrive organically within the ecosystem. Transactions, in the form of a merkle tree Mining computers collect enough transactions to fill a block and bundle them into a merkle tree. A merkle tree is a relatively simple concept: transactions lie at the bottom of the tree as leaves and are hashed using the SHA function. The combination of two leaf transactions are hashed again using the SHA function to form a parent of the leaves.

This parent is continuously hashed upwards in combination with other parents of hashed transactions, until a single root is created. The hash of this root is effectively a unique representation of the transactions that are underneath it. A visualization of how a merkle tree is built — the leaves at the very bottom of the tree are transactions The root of the merkle tree is a combination of the hashes of every transaction in the tree.

Recall that for any any input to a hash function, the output is entirely unique. Therefore, once most nodes on the network receive a mined block, the root of the merkle tree hash acts as an unchangeable summary of all the transactions in that given block. If a malicious actor were to try and change the contents of a transaction in a block, its hash would be changed. The block header The block header is a summary of the contents of the block itself.

It contains the following six components: The version of software the Bitcoin client is running The timestamp of the block The root of its containing transactions' merkle tree The hash of the block before it A nonce The target Remember that the root of the transaction merkle tree acts as an effective summary of every transaction in the block without having to look at each transaction. The hash of the previous block before it allows the network to properly place the block in chronological order.

This is where the term blockchain is derived from — each block is chained to a previous block. The nonce and target are what make mining tick. They are the basis for solving the SHA puzzle that miners need to solve. Please note that all of this data in the block header is compressed into 80 bytes using a notation called little-endian , making the transfer of block headers between nodes a trivially efficient process.

Explaining the Mining Problem The target stored in the block header is simply a numeric value stored in bits. Recall that the output of SHA is just a number. For years the square-set method was the most effective means available for pillar recovery. However, in areas where bad ground was encountered, square setting was a costly and sometimes hazardous method.

As the tonnage mined from pillars increased, it was apparent that a safer and less expensive approach was required. Past experience indicated that the best way to deal with broken ground was to mine from the top down. However, ideas generated from studying top slicing finally developed into the present method of undercut-and-fill. The result is more accurate scheduling of pillar production. Undercut-and-fill is a method of extracting a block of ore by mining successive cuts, working from the top down.

Round logs covered by a wire screen are laid across the stringers to form a mat. The cut is then tightly filled with hydraulically placed cemented sand fill. Mining is then resumed on the cut immediately below the mat. As the cut advances, the timber stringers are supported by round timber posts seated on the solid bottom of the cut. Drilling, blasting, muck removal, and timbering operations are repeated until all the ore in the cut has been removed.

At this time, another log mat is laid and the cut is filled. This sequence is continued until the block has been mined from level to level.
