Digital Asset Solution Coin is a proof-of-stake cryptocurrency. Digital Asset Solution Coin has its unique proof-of-stake algorithm different way of design comparing with any implementation of the coin age concept used by other proof-of-stake cryptocurrencies and is resistant to so-called nothing at stake attacks. A total quantity of 1 billion available tokens were distributed in the genesis block. Curve25519 cryptography is used to provide a balance of security and required processing power, along with the used of SHA256 hashing algorithms.
Generating Blocks in every 60 seconds, on average, by independent accounts on network nodes. Since the full token supply already exists, Digital Asset Solution Coin is redistributed with the inclusion of transaction fees which are awarded to an account when it successfully creates a block. This process is known as forging and is like the mining concept that are used by other cryptocurrencies. Transactions are deemed safe after 30 block confirmations, and with the Digital Asset Coins current architecture and block size cap allows for the processing of up to 300.000 transactions per day.
Digital Asset Solution Coin transactions are based on a series of core transaction types that are not require any of script processing or transaction input/output processing at the network nodes side. These transactions allow core support for: asset exchange, alias registration, encrypted messages, digital goods store, monetary system, voting system, phased transactions, account control, shuffling, account properties, cloud data
Digital Asset Solution Coins core can be recognized as an agile, base-layer protocol upon which a limitless range of services, applications, and other currencies can be built.
The value of Bitcoins is constantly fluctuating according to demand. This constant fluctuation will cause Bitcoin accepting sites to continually change prices. It will also cause a lot of confusion if a refund for a product is being made. For example, if a t-shirt was initially bought for 1.5 BTC, and returned a week later, should 1.5 BTC be returned, even though the valuation has gone up, or should the new amount (calculated according to current valuation) be sent? Which currency should BTC tied to when comparing valuation? These are still important questions that the Bitcoin community still has no consensus over.
Digital Asset Solution Coin purpose is to develop more stable coin environment. In which every coin of Digital Asset Solution Coin will be backed up by real asset that are offered in the marketplace. One which is trade at the marketplace is the tokens not the coin itself. Every transaction related to token trading will be subject for a fee in the form of Digital Asset Solution Coin coins.
Existing blockchain contracts can only perform simple smart contract computations, the blockchain addresses the transmission and accounting of decentralized value networks. Bitcoin uses a SHA256 Proof of Work (PoW) for consensus on the computational contribution, with each block divided into three parts, namely:
- The hash value of the last block serves as the block header of the current block.
- Pending transactions (t1, t2,_ _ _,tn) within the time window T will be hashed into block Coinbase; and
- Including miner’s address, which is normally the address of mining pool, the X, as the input of hash functions, will be dispatched by pool server to each miner, who will complete certain computations. The goal is to find H (X; nonce) < Target Difficulty, where nonce is an appended randomized guessing number. The computation result will be verified by the whole network nodes so as to get the reward out of the block to the exact miner’s address, and then the whole network enters the computation of the next block, thus forming a chain eventually. In addition, there are some other information, such as version number, Merkle tree, timestamp, etc.
The whole mining process can be summarized as:
SHA256(SHA256(version+prev_hash+merkle_root+ntime+nbits+nonce)) < TARGET Ethereum makes use of uncle blocks  to improve network concurrency. In particular, both the Ethereum network and the Rootstock  network is designed for smart contracts on the chain. The consensus and tamper-proof of make blockchain automatically ensures the enforcement of the contract, contract execution, and funds allocation, thus eliminating the trust and dependence on people or other third parties.
In the process of optimizing the objective function, various numerical methods are often used to iteratively gradient descent to find the global optimal solution. Large-scale distributed learning often adopts ASGD (asynchronous stochastic gradient descent) to optimize the results. Sometimes, for particular problems, the training can only obtain a sub-optimal solution at a certain distance from the global optimum according to a distribution.
Instead of PoW (proof-of-work), Digital Asset Solution Coin relies (PoS) Proof-of-Stake algorithm to reach consensus. But what is the difference?
Cryptocurrencies such as Bitcoin which use PoW, require mining. To mine, expensive computer hardware is required and utilized to solve very complex mathematical problems to earn the rewards. It’s considered very expensive.
On the other hand, under PoS creators of new blocks are selected deterministically- based on their wealth. This is far much more cost-effective. The other implication here is that since Digital Asset Solution Coin does not require mining, there is a static supply of money.
In addition, the network is less susceptible to hacks. To hack a PoS network, hackers would need to invest massive amounts of the currency, and this is likely to devalue their holdings.
The Digital Asset Solution Coin ecosystem is fueled by Digital Asset Solution Coin as its virtual currency. Digital Asset Solution Coin tokens can be used for the following:
- To cover transaction fees when transferring Digital Asset Solution Coin between users.
- Creating assets representing bonds or ownership of projects.
- Deploy decentralized polls within a Blockchain.
- As a digital currency for exchange during ordinary purchases
