Bitcoin’s blockchain, while revolutionary, faces significant scalability challenges that could hinder its long-term adoption. The primary issue stems from Bitcoin’s limited transaction throughput. Currently, the Bitcoin network processes only around 7 transactions per second (TPS), far fewer than centralized payment systems like Visa, which can handle thousands. This limitation results in slower transaction times and higher fees, particularly during periods of high demand, making Bitcoin less practical for everyday use.

Several proposed solutions aim to address these scalability concerns. One of the most notable is the Lightning Network, a second-layer protocol built on top of Bitcoin’s blockchain . The Lightning Network enables faster transactions by creating off-chain channels between users, allowing them to transact instantly and at a lower cost. These transactions are later settled on the main blockchain, improving scalability without compromising security.

Another proposed solution is Segregated Witness (SegWit), which increases the block size limit by separating the transaction signature data from the rest of the transaction. This allows more transactions to be stored within each block, boosting throughput.

Lastly, Sharding, a technique used in other blockchain networks, is being explored as a future solution. It involves splitting the blockchain into smaller, more manageable parts (shards), each processing its transactions concurrently, thus enhancing overall capacity.

These solutions, though still evolving, hold the potential to overcome Bitcoin’s scalability challenges and pave the way for broader adoption.
