The off-chain solutions could be exploited by the developers to have more scalability without losing key aspects of Bitcoin, that is, security and decentralization. Perhaps off-chain execution of complex agreements and transactions on the main Bitcoin blockchain represents a very promising avenue by ensuring better efficiency and versatility.<\/p>\n<h3><strong>Overview of Bitcoin Smart Contract Platforms<\/strong><\/h3>\n<p><span style=\"font-weight: 400;\">Even though the base layer of Bitcoin was not designed for use in complex <a href=\"https:\/\/www.antiersolutions.com\/smart-contract-development\/\" target=\"_blank\" rel=\"noopener\"><strong>smart contracts<\/strong><\/a>, such a gap has been bridged by Layer 2 solutions. These kinds of layers rest on the large security model of Bitcoin and enable further programmable transactions than usual.
