The blockchain is an ever-growing list of records, called blocks, which are linked together using cryptography. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. Bitcoin nodes use the block chain to differentiate legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere.
The primary purpose of mining is to allow Bitcoin nodes to reach a secure, tamper-resistant consensus. Mining is also the mechanism used to introduce bitcoins into the system. Miners are paid transaction fees as well as a subsidy of newly created coins, called block rewards. This both serves the purpose of disseminating new coins in a decentralized manner as well as motivating people to provide security for the system.
Bitcoin miners are neither able to cheat by increasing their own reward nor process fraudulent transactions that could corrupt the Bitcoin network because all Bitcoin nodes would reject any block that contains invalid data as per the rules of the Bitcoin protocol. Consequently, the network remains secure even if not all Bitcoin miners can be trusted.
The blockchain hit capacity is a limit on the number of transactions that can be processed per second. The limit is due to the 1 megabyte block size limit of the Bitcoin protocol.
The Bitcoin network can currently process approximately seven transactions per second. The Ethereum network can currently process approximately fifteen transactions per second.
As the number of transactions on the blockchain increases, the need for faster transaction processing increases. However, the block size limit of the Bitcoin protocol means that the network can only process a limited number of transactions per second.
There are a few possible solutions to the blockchain hit capacity problem. One solution is to increase the block size limit to 2 megabytes. Another solution is to implement a second-layer solution such as the Lightning Network.
The Lightning Network is a second-layer solution that uses off-chain payment channels to process transactions. The Lightning Network can process approximately one million transactions per second.
The Lightning Network is not yet widely available. However, it is expected to be available soon.
The most likely short-term solution to the blockchain hit capacity problem is to increase the block size limit to 2 megabytes. This solution will allow the Bitcoin network to process more transactions per second.
The long-term solution to the blockchain hit capacity problem is to implement a second-layer solution such as the Lightning Network. The Lightning Network will allow the Bitcoin network to process more transactions per second.

Q: How long will it take for Bitcoin to reach max supply?
A: Bitcoin’s maximum supply is 21 million.
Q: How much can blockchain hold?
A: There is no definitive answer to this question since it depends on a number of factors, including the size of each individual block and the overall design of the blockchain. However, it is generally accepted that a blockchain can theoretically hold an unlimited amount of data.
Q: Can the Bitcoin block size be increased?
A: The Bitcoin block size is 1 MB.
Q: How big will the blockchain get?
A: There is no one answer to this question as the size of the blockchain will depend on a variety of factors, including the number of transactions being made on the network, the size of each transaction, and the frequency of blocks being added to the chain. However, it is estimated that the blockchain could eventually grow to be several terabytes in size.
