the key is to keep faith[ [coin an community]
coinbase transaction is a special transaction that generates bitcoin "out of thin air". Only miners can write this kind of transaction, and the number of generated bitcoin is limited by rules (new currency reced by half for every 210000 blocks + transaction fee for this block)
however, the rules do not stipulate that the miner must take away all the rewards that can be taken, and can choose not to take them
therefore, a mine pool connected with the RSK side chain has made a bug before, forgetting to take away the reward and occupying a pit in a block for nothing, which is equivalent to destroying the corresponding amount of bitcoin, making the total amount of bitcoin decrease a little bit permanently
in addition, to spend a bitcoin, you only need to specify the transaction ID and output serial number
as like as two peas in multiple blocks repeatedly write identical coinbase transactions, the transaction ID is also repeated.
therefore, this kind of situation also occupies the pit of a block in vain, and permanently destroys the corresponding amount of bitcoin
it seems to me that this is still a security vulnerability, so the new version of bitcoin software later banned the writing of repeated coinbase transactions. But until now, there has been no ban on miners not getting their e rewards
generally speaking, a coin is controlled by a private key. If a coin is transferred to an address where no one knows the private key, it will be destroyed
if the owner does a good job in security, and the private key is not disclosed and cannot be guessed, but he accidentally loses the private key, it is equivalent to destroying all the coins he owns
there are only some special circumstances that require intentional destruction of coins
one is irreversibly converted into another kind of currency, such as the contract currency XCP attached to bitcoin and wormhole cash WHC attached to BCH
the second is to save certificates and data on the chain, such as the time stamp: panbiao.com/2013/08 /
and the crowd funding of the original Ethereum founding team: zhuanlan.hu.com/p/29
the private key is essentially a big number. Whoever knows this number can control the currency on the corresponding address. So the private key must be generated with reliable random number, otherwise it may be guessed and stolen
compared with the token, the address is the hash of the public key. There is no way to judge whether an address has a corresponding public key and private key (even if the public key is known, the corresponding private key cannot be known). Therefore, even if it is explicitly the address of "burned" token, the system does not prohibit the transfer in
strictly speaking, what locks the currency is a small program (script). This program takes the input as the public key and digital signature. First, check whether the public key hash is consistent, and then check whether the digital signature is valid. If it is valid, it will be verified and transfer is allowed; Otherwise, it will be judged that the transaction is illegal and refuse to package into the chain
it is the whole node software that explains and executes this program. It can be said that the software code of the whole node specifically defines a coin
however, the current situation is very embarrassing. Most miners do not run the whole node, only a few mines are running. The vast majority of users do not run the whole node, even if they run the whole node, they can only perform verification, no computing power, no block
many people don't understand what side chain is. This concept comes from bitcoin community and was put forward in December 2013. There are some problems with the birth of bitcoin itself or the mechanism of a blockchain itself. But if you modify bitcoin protocol or chain directly, it is easy to make mistakes. Moreover, because the bitcoin block has been operating continuously, if it is wrong, the amount of funds involved will be very large, which is not allowed
in fact, sidechains do not refer to a particular blockchain, but to all blockchains that comply with the side chain protocol. This term is relative to the main chain of bitcoin
for more information, what is a side chain
RSK smart contract is a smart contract platform based on bitcoin blockchain. RSK (rootstock) has been an eye-catching development platform since its concept was proposed. In essence, RSK is to build a decentralized and Turing complete intelligent contract platform similar to Ethereum. However, RSK is based on the bitcoin ecosystem rather than an independent blockchain. The specific way is to use the side chain technology. This approach has both challenges and great advantages
smart contract platform:
smart contract is the current research hotspot. Nick Szabo came up with the idea 20 years ago. Generally speaking, it is an electronic contract that can be executed automatically based on trigger conditions. Smart contract is the next generation of procts to realize automatic execution in various business environments, which may subvert the existing business model. For example, on-demand economy, such as insurance contract customized according to each journey, reaching the set end of the journey or writing a program to determine, and then the insurance contract ends. This insurance mode can even be connected to P2P mode, which makes traditional insurance companies useless. These simple examples can be realized through RSK smart contract platform
The advantages of RSK:
RSK has many innovations. Firstly, Turing complete virtual machine is compatible with Ethereum virtual machine. Ethereum contracts can be run on RSK virtual machines. The goal of RSK is to achieve 20 seconds block time and 300 transfer transactions (TPS) per second at the first launch, which can be expanded to 1000 TPS. It has reached the level of PayPal, but it has not reached the throughput of credit card network. Compared with other platforms, the biggest advantage of RSK is the combined mining of bitcoin, and the security level is equal to that of bitcoin network. But it also needs to persuade miners to implement. RSK revealed that they will make miners profitable, and the implementation of the contract round fees will make miners profitable. It is likely that the RSK platform will be very popular and the contract execution will reach a stable level
