Reading through the PR material provided by projects developing DAG technology, it might appear as if the second coming of our lord and savior Nakamoto is upon us. While DAG technology is indeed a highly promising development in the realm of decentralized ledgers, the reality is, as always, slightly more complicated.
This means that they represent a record of events in a network such as transactionswhich is shared and agreed upon by all network participants. Blockchains achieve this universal record by grouping transactions into so-called blocks, which are then verified in relatively slow intervals, while cryptographically linked to the previous and following block.
This means that a node wishing to perform a transaction is required to verify the transactions of at least two other nodes, creating an ordered sequence of linked events. In this example, transaction number 6 is required to validate transactions 3 and 5, further validating 1 and 0 while doing so.
Transaction 6 will now sit there quietly and wait for 9 to return the favor. Sharp-eyed readers might at this stage already recognize the enormous potential and failure capacity of this approach.

Scalability Traditional blockchains have two attributes that make the network less efficient as it grows. The first has to do with how blocks are mined, or validated. The second concerns the way in which the record of validated blocks is stored.
In a blockchain network, miners, or validating nodes, compete to sign the next block.
No matter how many nodes participate in this process, it is always only one of them which eventually seizes the opportunity to do so.
With transaction density increasing in growing networks, this method becomes very slow, very quickly. Secondly, the record of all past transactions e. The Bitcoin blockchain, for example, is currently about GB large. Multiply this by the myriads of nodes in the respective networks, and you get the picture.
DAGs present a potential solution for both of these problems. Eventually, all shards overlap to some extent and connect like some sort of puzzle, which, reconstructed, constitutes the ledger in its entirety.
The lack of blocks and the mining thereof bear the potential of allowing zero, or close to zero transaction costs. This alone would be a killer feature and immensely useful for microtransactions and IoT use-cases.
To mitigate this situation, most leading DAG projects sort of cheat.
Overall, the mesmerizing beauty of the tangle structure comes at the price of a serious dependability problem. DAGs perform outstandingly in certain cases, but become unstable, stagnant, or unreliable in others.
A situation most DAG projects deal with by introducing centralized elements. And then this happened. Alternatives are of course worked upon. However, they are still considerably cheaper than Bitcoin or Ethereum transactions. Given all this information, what is your take? Are DAGs the ledger of the future, or just another weird animal in the blockchain zoo with limited use-cases?

NANO for example tends to have a transaction speed of 10 seconds instead of 3 seconds at Binance and all that for major compromises on security and transparency.
DAGs are commonly used to model data in a wide variety of practical applications, ranging from XML documents and data provenance models, to web taxonomies and scientific workflows.

Sep 19, · is the play at 1k/2k really bad enough to justify playing it (with an implied edge) despite being unsure of the answer to this question!? My analysis considered the worst case as well, where villain will rarely bluff on the end so hero can't figure on winning a big bet on 7th -- only losing one when he is beat.
