A common criticism of various blockchains is their poor scalability. Well-known, well-established, and often older blockchains like Bitcoin and Ethereum can be expensive and slow to use. This article explains what blockchain block time is and how it affects the scalability of a blockchain.
What is the blockchain?
A blockchain is a distributed database shared between nodes on a computer network. This database records all the transactions that occur on this network. An important distinction between a typical centralized database and a blockchain is how the data is structured.
Some of the most popular databases in the world today are relational databases. A relational database is a collection of data elements with predefined relationships between them. These data elements are organized into tables that consist of columns and rows. On the other hand, a blockchain collects information in chunks called blocks.
Blocks are a collection of data that has been grouped together. Often on a blockchain, this data will be a list of transactions. These blocks also contain the hash of the data from the previous block, as well as the data these blocks contain. Thus, the structure of a blockchain is similar to a single-link list, with a block containing the hash of the previous block rather than a pointer to the previous block. The hash function ensures that the blockchain remains immutable because any changes made to previous blocks will be evident by a change in the block’s hash.
Another key difference between blockchains and other types of databases is decentralization. In a blockchain database, no centralized authority has the power to make changes to the database or add data to the database. Instead, consensus protocols are used to get different nodes on a blockchain to agree on the correct state of the blockchain on a peer-to-peer basis.
What is the blocking time?
Blocks in a blockchain have certain storage capacities in terms of the amount of data a single block can store. As mentioned above, the data stored in blockchain blocks is usually a list of transactions. When a block reaches its capacity, it is closed and linked to the previous block. All data that arrives after adding this block is compiled into a new block. This block will also be added and linked to the blockchain once it reaches capacity.
Block time refers to the time it takes for a blockchain to create a new block. It is the time interval between the creation of each new block in a chain of blocks. The block time of a blockchain is determined by several different factors.
These factors for proof-of-work blockchains can include the complexity of the hash being resolved and the available computing power or hash rate. Bitcoin’s lock time is currently around 10 minutes, while Ethereum’s lock time is currently 10-15 seconds. The protocols behind these blockchains will periodically adjust the mining difficulty to ensure that the average block time of the blockchain remains the same.
The block size dilemma
The block size is what determines the amount of data that can be stored in each block. Therefore, if a blockchain were to increase its block size, the blockchain would be able to increase the number of transactions per second that it can process.
However, there are many drawbacks to increasing the block size. Larger blocks will grow the blockchain faster and make full nodes more expensive to operate. Full nodes are nodes that store all of the blockchain data on a hard drive instead of a shorter, stripped-down version. As the blockchain grows faster, so does the amount of data that full nodes must store.
This change will increase the data storage costs of full nodes. Rising costs may lead to further centralization as it could deter users from operating full nodes or induce users who operate full nodes to stop doing so. Any decrease in the number of users operating full nodes leads to an increase in network centralization.
Workarounds to increase block size
There are various alternatives to increase the block size when it comes to improving the scalability of a blockchain. An alternative is the use of Layer 2 solutions. Layer 2 is a term used to describe a secondary protocol built on top of an existing blockchain.
In this second layer, blockchain transactions and processes can take place independently of the original blockchain while benefiting from the decentralization and security of the original blockchain.
Examples of Layer 2 solutions include the Bitcoin Lightning Network and the Polygon Network. Another alternative to improve scalability is to reduce the lock time. However, decreasing the block time has many drawbacks, including limited ability to scale due to retransmission time. The retransmission time is the time it takes to transmit a new block to each node on the blockchain. If the block time falls below the retransmission time, a new block will be generated before all nodes in the network can receive the old block.
How is the block time different for Bitcoin, Dogecoin and Ethereum?
Depending on the blockchain network used to secure a cryptocurrency, the block time will be different. Dogecoin’s lock time, which is a fork of Litecoin, is every 1 minute, compared to Bitcoin’s lock time of 10 minutes and Ethereum’s lock time of less than 15 seconds.
Get started in cryptocurrencies
A good place to buy your first cryptocurrency is from a centralized exchange. These centralized exchanges allow customers to buy cryptocurrencies with US dollars. Some of the most popular centralized exchanges are Coinbase Global Inc. (NASDAQ: COIN), Gemini, and Voyager. These exchanges provide easy-to-understand user interfaces that can be helpful for investors new to the crypto space. Centralized exchanges are also regulated by the US government and follow Know-Your-Customer (KYC) laws. To comply with these regulations, you provide the Centralized Exchange with personally identifiable information. Then, you connect your bank account to your exchange. Once your account is funded, you can buy cryptocurrencies available on the exchange.
Gemini is a cryptocurrency exchange and custodian that offers investors access to 26 coins and tokens. Founded in the United States, Gemini is expanding globally, particularly in Europe and Asia. The offerings include major cryptocurrency projects like Bitcoin and Ethereum, and smaller altcoins like Orchid and 0x.
Gemini is one of the only brokers to offer multiple platform options based on skill level. New traders will love the streamlined interface of the Gemini mobile and web app, while advanced traders will appreciate all the tools ActiveTrader includes.
In addition to a plethora of platform options, Gemini users also have access to secured hot wallets to store tokens without worrying about digital asset theft. Learn more about what Gemini can do for you in our review.

Why is block time important in crypto?
Blockchain time is important because it affects network performance. However, smaller block times are not always better due to network lag time. Additionally, block times have limited ability to help blockchains scale, and alternate updates to other parts of the blockchain protocol, such as its consensus mechanism, will have a much greater impact on a blockchain’s scalability. net.
