quicken bookkeeping

accounting systems can freely transmit money to each other through a third-party "connector" or "authenticator" machine. The bookkeeping system does not need to trust the "connector" because the protocol uses a cryptographic algorithm to create funds for these two accounting systems and connectors, and when all participants agree on the amount of money, they can trade with each other. ILP removes the trust required by the trading participants, the co

individual or group in the world can send a transaction, and a transaction can obtain an effective confirmation of that blockchain, and anyone can participate in its consensus process. Private chain: Only use the Blockchain's general ledger technology for accounting, can be a company, can also be a person, exclusive access to the blockchain write permissions, this chain and other distributed storage scheme is not much different. Union chain: By a group of designated multiple pre-selected nodes

node in the network to participate in the recording and verify the correctness of other nodes ' record results. Only when most nodes (or even all nodes) of the whole network think this record is correct, or if all the nodes participating in the record are passed unanimously, the authenticity of the records can be recognized by the whole network, and the record data is allowed to be written into chunks. 2. With regard to how to store the "blockchain" rigorous database, the blockchain approach is

When accounting staff use manual bookkeeping, there will be a balance after "borrow" and "loan", which is the accumulated balance, that is, after each account is recorded. If you use computer bookkeeping, you can complete the calculation of the accumulated balance by querying. First, the establishment of the table (assuming the save name is "financial balance"), the table in addition to the date, borrow, c

parallel OID collector.Concurrent-mark-sweep (CMS) is an alternative that allows the application thread to continue running in most garbage collection cycles, but this is a cost, and there are some caveats.Allowing the application thread to run with the garbage collection thread inevitably poses a problem: The application thread modifies the object graph, which can affect the survivability of the object. This situation must be cleaned up afterwards, so the CMS actually has two STW phases (usual

protected method is called when this task transitions to the state isDone (whether normal or canceled). The default implementation does not perform any action. Subclasses can override this method to invoke completion callbacks or to perform bookkeeping. Note that you can query the state within the implementation of this method to determine whether the task has been canceled.The subclass Queueingfuture overrides the Done () method, and when the task i

. Partitioning is another way to achieve scalability, by contrast, it needs to know the structure of the input data, such as the scope of the primary key, or the name of the file to process. The advantage of this pattern is that the processor for each element in the partition can be considered a single step in the normal spring batch work. They do not implement any particular pattern and are therefore easy to configure and test. Partitioning is more scalable than remote segmentation because the

The block chain can be understood as a distributed database, read data, and store data. Features are: durability, robustness, transparency, not destructive. At this time there are alumni asked: "Teacher, other people said that the block chain is a distributed ledger, there is an incentive mechanism, can be dug to get rewards, how different." ", the question is very good schoolmate, said also to, but has the limitation, is consistent for the bitcoin, but the bit currency that is the block chain 1
