The concept of programmable money
What is the first thing that comes to mind when you think of Bitcoin? Most of the responses would concern bitcoin being a decentralized approach to send money from one person to another electronics without any intermediaries. You should know that Bitcoin’s main objective was to create an electronic cash system that allowed Bitcoin owners. The answers to “What are scripts in Bitcoin?” Provide a new perspective with Bitcoin transactions. The bitcoin script is almost similar to the introduction of smart contract features in the Bitcoin blockchain.
Bitcoin script is a programming language based on the battery that helps create more complex transactions that involve specific conditions. Bitcoin scripts are small programs that define the conditions under which a specific quantity of bitcoin chips can be spent. You can send Bitcoin to someone with a locking script that describes how bitcoin can be exchanged in the future. The recipient must use a unlocking script corresponding to the locking script to spend the Bitcoin chips received.
Bitcoin script work mechanism
The best way to understand how the Bitcoin script works is learning the concept of batteries in programming. Have you heard of the LIFO data structure? It represents the last first output structure in a database. Think of a pile of plates to which you can add a plate only at the top and remove a plate only from the top.
The work mechanism of the Bitcoin script is almost similar to the structure of LIFO data. The validation of a Bitcoin script transaction consists in combining the locking script and unlocking the script and running them on a virtual machine. It is important to remember that the locking script comes from the release of the previous transaction and that the unlocking script comes from the entry of the current transaction.

Technical details on the operation of the Bitcoin script
The overview of the work mechanism of Bitcoin scripts only offers a simple way to understand technology. You should also know more about the technical aspects of the Bitcoin script execution process to familiarize its operation. The following steps in the Bitcoin script process will bring more light to its importance in cryptographic space.
The main essence of Bitcoin script language in the blockchain concerns the two scripts that define the Bitcoin script. The locking script or the scriptpubkey is one of the information from the previous transaction. It provides the conditions which must be followed to spend the bitcoins sent in the transaction.
The unlocking script or the scriptsigs includes part of the information in the entry of the existing transaction. The scriptsig offers descriptions of the operations and data necessary to meet the scriptpubkey requirements. You can notice that the locking script serves as locking on the Bitcoin tokens sent to a transaction while the unlocking script is the key to unlocking the tokens.

Combine and execute the scripts
The next crucial step in the Bitcoin operating scenario is the concatenation process. The Bitcoin node checking a transaction will take the scriptsig of the entry and will combine it with the scriptpubkey of the exit it wishes to spend. The execution of the script combined in an important step on the battery defines an aspect crucial in the functioning of the Bitcoin script.

Data and opcodes
The most important highest point in any Bitcoin script guide concerns the usefulness of opcodes and data elements. Since the Bitcoin script is a programming language based on the battery, it relies on predefined commands, called OPCODES codes or operating codes. Operating codes help carry out various actions on the data pushed on a battery. It is also important to recognize the use of data elements such as signatures, atmosphere and public keys in Bitcoin scripts.
The validity of a transaction depends on the successful execution of the Bitcoin script. You can confirm a successful execution when the upper element of the battery at the end of the execution is a non -zero value. On the other hand, an error or a “false” result at the end of the execution means that the transaction is not valid.

Example of Bitcoin script transaction
After learning the technical aspects of Bitcoin scripts, you might be curious to experience an example. The example of the most popular Bitcoin script is the Pay-to-Public-Key-Hash or P2PKH transaction script. P2PKH implies the simplest Bitcoin transaction in which you send Bitcoin to another Bitcoin address. This sequence of Bitcoin scripts guarantees that only the person with the private key for the hash public key can unlock the transaction to spend Bitcoin tokens.
Various ways to use Bitcoin scripts
Bitcoin scripts do not provide a single option to send Bitcoin from one address to another. You can explore many other use cases or variations in Bitcoin scripts which have the usefulness of programmable money. Bitcoin Script offers the possibility of adopting the following cases of large -scale Bitcoin.
The list of different cases of using Bitcoin scripts also draws attention to the possibility of using Bitcoin in transactions locked over time. You will find two types of Bitcoin scripts for transactions locked over time, such as ChecklockTimeVIFY and Checkssencecen. The two scripts help lock the bitcoin tokens or the funds for a specific period or until a specific block height is obtained.
The CLTV Bitcoin script follows the BIP65 standard and locks the funds for a time of time or a specific block number. He uses a horodat or a block number as a unlocking the script. The CLTV script is the best choice to create special testaments and payment channels or locking funds to allow them to mature over time.
The CSV script created with the BIP68 standard is almost the same as CLTV. CSV finds applications in advanced layer 2 protocols such as the Lightning network to guarantee the equity of contracts and the application of expiration.
Even if the work mechanism of the Bitcoin script shows no sign of exhaustiveness of Turing, it can manage conditional logic. Therefore, Bitcoin scripts can be the best choices for conditional payments where a key or secret can unlock funds.
Remuneration or P2SH is a standard BIP15 Bitcoin script which is ideal for complex payments. It helps relieve the burden of the full shoulders of the sender. The sender can only send tokens to the hash script and the recipient can reveal the real script during expenses. The P2SH script represents complex transactions as standard address payments, thus reducing the size of transactions and improving confidentiality.

Why is the bitcoin script complete?
Discussions on the Bitcoin script also draw attention to the possibilities of similarity with solidity, the programming language of Ethereum. Depending on no one, the bitcoin script is largely different from solidity because it is not complete. Why did the Bitcoin script omit a common trait of expressive programming languages? The use of the Bitcoin script language in the blockchain does not imply the execution of complex conditional instructions and arbitrary loops. Although many of you may think that this is a limitation of the Bitcoin script, it is extremely important for the safety of Bitcoin.
Malventy actors can use scripts that run endless loops to create transactions that take a huge share of the IT resources of the network. The predictable and finished execution path of each Bitcoin script guarantees that nodes can easily check different transactions. As a programming language with fewer complexities, the Bitcoin script will guarantee a reduced number of potential vulnerabilities and bugs.
Benefits and limitations of the Bitcoin script
The Bitcoin script introduces the possibilities of using intelligent contracts on the Bitcoin blockchain. Despite its simplicity, the Bitcoin script process offers various advantages. The first advantage of the Bitcoin script is the assurance of better security and better flexibility to execute sophisticated transactions. The most important thing of all, the Bitcoin scripts will widen the room to innovation with the Bitcoin blockchain. However, it is also important to remedy the notable limits of the Bitcoin script such as debugging challenges and the largest size of transactions.
Final reflections
Bitcoin script is a perfect example of the use of innovation to improve Bitcoin blockchain. Bitcoin script is not only a programming language, but also a way to introduce the concept of programmable money with Bitcoin. One of the notable things you can learn from this Bitcoin script guide is the fact that the Bitcoin script is not complete and which guarantees many advantages. The most important thing to know about Bitcoin scripts is that it will transform Bitcoin from a reserve of value to an electronic cash system with various public services.
