What You Should Know About Bitcoin Smart Contracts?


Decentralization is one of the advantages of cryptocurrency and blockchain. This implies that no central authority will oversee or officiate any transactions you conduct with Bitcoin and other altcoins. That’s where Bitcoin smart contracts come into play, which we will discuss shortly.

First, you must understand that smart contracts are the foundation of the decentralized world. However, we are aware of how important crypto and its underlying concept of smart contracts are, particularly when it comes to financial matters and the requirement for two parties to agree to several conditions before concluding or signing a deal.

Because the crypto space continues to process millions of transactions without any middlemen, how do crypto companies manage this aspect of the space? The solution is smart contracts. 

Let’s shed some light on Bitcoin smart contracts and understand what smart contracts are, in general? Read on to find out.

What are Bitcoin Smart Contracts?

Bitcoin smart contracts are a wide range of codes based on its scripting language, called Script, that establish criteria for a bitcoin to be spent, transferred, or utilized in any form. As such, bitcoin transactions can only be carried out successfully as predefined in Script codes. Thus, bitcoin smart contracts are automatically executed when predetermined terms and conditions locked to the Script are met.

Smart contracts in general, are software programs stored in a blockchain network node that runs under designated conditions. With a clear analysis of some financial protocols, they enable safe value exchange and carry out the agreement automatically, without an intermediary.

Investors also use these contracts to build buyer-seller confidence and facilitate easy transactions. However, a Bitcoin smart contract is not an exception to these contracts.

Like every other smart contract, a bitcoin smart contract analyzes the rules that the two parties to the transaction will agree upon and is a digital agreement that spans all blockchain nodes. By eliminating mediators, these digital money contracts enable the exchange of priceless digital assets.

As bitcoin uses a blockchain as a ledger to record all transactions, once it copies bitcoin smart contracts the data, in any case, could not be altered. This is because codes that run on the blockchain can not be changed or tampered with. Like other smart contracts, blockchain smart contracts make forehand rules and fulfill their obligations with the least amount of human interference.

Types of Bitcoin Smart Contracts

Different smart contracts handle diverse tasks and business needs in the crypto space. Hence, there are different types of Bitcoin smart contracts. Here are some of them.

1. Pay-to-Public-Key-Hash (P2PKH)

The P2PKH scripts smart contract ensures that only the person with the corresponding private key spends a specific amount of Bitcoin assigned to that address. Positively, to spend Bitcoin, P2PKH scripts require you to provide a specific ECDSA signature that is the same as the public key whose hash is provided by the script.

Because no one else can generate a valid signature whose hash matches the hash of the public key, the holder of the private key is the one who is legally entitled to the bitcoin. It is the most well-known contract because of its utility and simplicity.

2. Multi-Signature Scripts

The M-of-N mutisign type of Bitcoin smart contract requires multiple signatures from any number of users, which can be chosen at random. It follows an outline of public keys and several signatures M which can be less than or equal to the number of owners  N. Only if multiple signatures are provided with corresponding owners can the Bitcoin in this script be spent.

Below is a typical example of a multi-signature script  2-of-3, which accepts two signatures from a group of three public keys. While ensuring that no one party is capable of theft, it enables three parties to hold money cooperatively. Decentralized p2p services benefit from 2-of-3 multisign for trust-minimized escrow.

3. Time-Locked Bitcoin Transactions

Transactions made with bitcoin can be time-locked, making them only valid after a specific period. As a part of the locking scripts, time locks can also be used to alter a bitcoin’s spending requirements. 

For example, a script might require three signatures before a certain time but only one signature after that to spend the bitcoin. This opens up alternative strategies, hopefully preventing a financial loss.

4. Pay-to-Script-Hash (P2SH)

As part of the segWit upgrade, the P2SH protocol was enhanced to a P2WSH-specific standard.  P2SH was developed with a specific objective in mind. Using P2SH and P2WSH smart contracts, Bitcoin can be sent to the hash of any script involving any of the previous examples. This design lowers the cost of sending bitcoin by utilizing a sophisticated smart contract and strong privacy protection before the bitcoins are spent.

Applications of Bitcoin Smart Contracts

Let’s say you own a home and use a smart contract to manage payments. In the future, your tenants may pay your rent without your intervention. These agreements will go a long way toward informing your tenant when and how to pay their rent and handling the settlement procedures simultaneously.

If the protocol outlined in the policy is to turn off the water to the apartments when they don’t pay, this automatically automates when the time is due. Everything returns to normal after payment. The smart contract also verifies receiving the payment, issues receipts, and records the transaction per the agreement on the Bitcoin (BSV) ledger.

As strange as it may seem, smart contracts will only permit deposits to the tenant’s account when the lease expires.

This holds for situations where there are two participants in fantasy sports betting or pools. The smart contract will automatically pay the winner after the competition is decided, reducing the likelihood of fraud. There is no requirement for outside assistance, and costs are decreased.

Bitcoin smart contracts guarantee security tradeoffs in the same way that cryptocurrency trading bots like bitcoin-revival automate crypto trading strategies and boost profits.

Smart contracts eliminate the need for brokers or other intermediaries to confirm the agreement. This way, there is no risk of manipulation by third parties, making the bitcoin network secure and reliable. 

Hence, they enhance business process effectiveness and ensure data security while serving as a digital replacement for paper-based contracts. Additionally, smart contracts save money because there are no intermediaries involved.
