How to broadcast bitcoin Wallet

1. bitcoin wallets are not very useful. You can download an okex with various wallets in it.

2. How to choose BTC wallet and how to store your bitcoin? This is an important problem that every bitcoin user must face. Bitcoin gives you more freedom and power to control your money. But if you are not careful, it may bring disastrous losses. If you choose to remain in complete control of your bitcoin on your own, then there is no one who can stop you from doing something stupid and pay for your mistakes. There is no bitcoin company to call and try to convince your legitimate owner of your address so they can give you the key back. However, there are friendly and secure services based on bitcoin, or intermediate solutions, which can let users avoid the risk of operating wallets. The purpose of this article is to explain what different options you have for storing BTC, so that each user can make the right choice between security and control. Wallets fall into two main categories: Online wallets online wallets are by far the easiest way to access your bitcoin from any computer. But there needs to be enough trust in wallet service providers. Currently, there are four main choices for online Wallet:

3. At present, there are a lot of digital currency wallets on the market. It is recommended to choose a well-known and official wallet, which is relatively safe. For example: bitpie wallet, fire coin, coin security, etc., but at present these apps can't be downloaded, you need to use a foreign account login app store to search.

4. The development is OK. I think it is more stable than other platforms.

5. no I just read about him.

6. Bitcoin receives payments almost instantaneously. However, there is an average delay of 10 minutes before the network starts adding your transaction to a block to confirm the transaction and that you can use the received bitcoin. Confirmation means that there is a consensus on the Internet that the bitcoin you receive is not used to pay others, so it is recognized as your property. Once your transaction is included in one block, all subsequent blocks will include it, which will greatly consolidate this consensus and rece the risk of transaction cancellation. Each user can determine the time when the transaction is confirmed, but generally speaking, receiving six confirmations is as safe as waiting six months after a credit card transaction
only full node clients like bitcoin core need longer synchronization time. Technically, synchronization is a process of downloading and verifying all previous bitcoin transactions on the network. Some bitcoin clients need to know all previous transactions to calculate the available balance of your bitcoin wallet and complete new transactions. This step consumes a lot of resources and needs enough bandwidth and space to store the whole block chain. In order to maintain the security of bitcoin, enough users need to use the full node client, because they play the role of confirmation and relay transactions.

Two statements for reference are found from Babbitt:

1. bitcoin adopts a mathematical contest to determine the time when a transaction arrives at a node, and at the same time to protect this order. In bitcoin system, transactions are sorted by group allocation, Such groups are called blocks (transactions occurring at the same time will be divided into the same block), and then these blocks are linked together, which is called blockchain. Blockchain is used to sort transactions, while the transaction chain tracks and records the change of bitcoin ownership. These blocks are arranged according to time, which is a link. Transactions not in the block are called unconfirmed or unsorted transactions, and any node is about to put a group of unconfirmed transactions into the block, Then broadcast their suggestions about what the next block should be to other nodes in the network
   If multiple people generate blocks at the same time (the probability is very small), there will be multiple choices for the next block of the current block. In order to ensure the sequence of block links, the bitcoin system requires each effective block to include the answer to a special mathematical problem, and the computer calculates the text of the whole block, In addition, random guessing based on encrypted hash can be done until an output lower than a certain value is obtained. Hash function can create a short summary from any length of text. This fixed output value is very complex. The only way to find it is random guessing, which is called mining

2. when King released PPC last year, it introced checkpoint mechanism to protect against attacks in its early development. This mechanism enables it to resist 51% attacks. " Developers can control a parent node and broadcast "checkpoints" to the whole network, which allows other nodes to agree on certain blocks“ This is actually a [blockchain] continuity warning message, "he said< br />
