Learning a bit about how Bitcoin works on a technical level makes it easier to keep your funds safe for the long term. By running a full node or a miner, you also play a role in protecting the network itself from bad actors and making decisions like whether or not to implement the latest fork. Forks are not inherently bad or good. Although forks can improve the network, they can also lead to devastating consequences like coin loss if rushed or badly implemented.
You may have already heard about Taproot or SegWit , the two latest soft forks that stirred up the community before eventually resolving to a consensus. In software development, the term fork is used when software is cloned in order to change the direction of a project. It can be modified to serve a different purpose or compete with the original project. A fork which stays compatible with the old version is called a soft fork, and one that breaks compatibility is a hard fork.
Bitcoin forks happen in order to change the rules of the network. To successfully fork, hundreds of thousands of computers must switch to a new version with the new rules enabled. This takes coordination and there are several Bitcoin Improvement Proposals BIPs related to the process, such as BIP9 which outlines a soft fork signaling process where miners can show they support a proposed fork before activating it. Forks depend on people accepting and using them, otherwise they are considered contentious forks, as not everyone is following the same rules, weakening the network.
In general, the fork with the greatest support wins. In the case of hard forks, they force those on the wrong chain to switch or continue mining an abandoned and mostly worthless chain.
Hard forks are to be avoided wherever possible, and approached with extreme caution when necessary. Bitcoin transactions form an unchanging history stretching all the way back to the genesis block , and confirmed transactions can not be changed without messing up every transaction that came after it. Through a hard fork, those transactions could be reordered to steal funds. Bitcoin has been hard-forked several times in the past, resulting in various spin-off cryptocurrencies, but only once was it forked in order to reverse transactions.
Forks are defined as hard or soft, depending on whether they continue to work with the existing network. Successful hard forks result in a chain split and a new currency being created. When a hard fork happens, users node operators and miners need to decide which chain they will support going forward. If a majority of users choose to support one chain, it is generally considered to be the winning fork, but both chains may continue to coexist indefinitely.
Examples of hard forks include Bitcoin Gold, Bitcoin Cash, and dozens of other attempts at changing how bitcoin works. In every case, these hard forks resulted in a new currency being created by cloning the Bitcoin blockchain and issuing new coinbase rewards to miners that supported the forked chain.
The new coins created through this process are not compatible with the original chain. A soft fork is backwards-compatible and does not create a new currency. Nodes running the new version of the software can still communicate with nodes on older versions.
New blocks are seen as valid by both new and old nodes, but older clients must abide the new rules for a transaction to be valid. Soft forks are the preferred method for implementing upgrades as they allow the network to continue running smoothly even if some nodes do not upgrade. For a decentralized system, it should be taken for granted that some participants will either choose not to upgrade, or simply not learn about the upgrade until much later. In , Bitcoin hard-forked in order to fix an exploit which created over 90 billion bitcoin.
This roll-back fork was a matter of patching the issue and then using a forked version of the blockchain from before the exploit happened, also reversing any transactions that came after it.
This would have been a big problem for anyone who sent or received a transaction at the time, or mined any blocks, but ultimately avoided the complete collapse of the network.
In , an accidental hard fork was caused when many miners upgraded to a new, incompatible version, and started mining a forked blockchain. This was fixed by reverting to the older version and abandoning the forked one.
Read the full post-mortem in BIP Both these hard forks happened for different reasons. While the resolution was quick, they would both have resulted in failed transactions and potentially coin loss for users on the wrong side of the fork. In these cases, hard forks reduced the damage that could have been caused by bugs and exploits. In that capacity, they are a very effective tool, but they can cause a lot of collateral damage to users in the process. Forks are a necessary way to upgrade Bitcoin.
Without them, there would be no lightning network, for example, which was dependent on the segregated witness SegWit soft fork. This facilitates more transactions to occur on the Bitcoin network. Interestingly, LN users don't have to connect directly with everyone they want to send BTC payments to.
Let's say you want to open a Bitcoin LN payment channel with your favorite pizzeria. You can deposit 0. Every time you pay for a pizza with BTC, a portion of your 0. So, if you bought one pizza for 0. However, you may not need to directly connect with your favorite restaurant. For instance, if your friend already has a connection with this pizzeria, you can connect to your friend's LN account and send your 0.
Here are a few main critiques experts have raised about its viability and security:. While the Bitcoin Lightning Network has a long way to go, it has already captured the crypto community's attention. As more wallets, exchanges, and businesses open up to the LN, it may become one of the most-used layer-2 solutions in crypto. We aim to put a share of our crypto in the hands of every individual on the planet for free. Subscribe to our blog to learn more about the cryptocurrency market.

Are there any downsides to the Lightning Network? Also, it's unknown whether businesses will tack on extra fees for using BTC as a payment option. Competition from other cryptocurrencies: Bitcoin may be the largest cryptocurrency, but many competing altcoins or non-Bitcoin cryptos can already process microtransactions faster and cheaper than Bitcoin's main chain.
Coins like Litecoin, Bitcoin Cash, and Dash have already made in-roads in the peer-to-peer payment space. Concerns of federal regulation: Since payments on the LN can theoretically pass through hundreds of users to reach their target, it can make transactions virtually impossible to track. Plus, remember that all transactions in the LN are off-chain. While these features may be a positive for users who value anonymity, they increase the likelihood that federal regulators will take issue with the LN.
Critics argue Bitcoin's reputation as a long-term investment might make users less prone to spend it as a daily currency. This is because the value per coin changes. Potential for hacks: Hackers can manipulate the LN to their advantage. Indeed, many LN developers have raised concerns over an attack called "flood and loot.
Theoretically, a hacker can take advantage of this confusion to siphon off funds before others realize what's happening. Unless the LN team develops cold storage solutions, this can compromise any bitcoins stored in payment channels. Other fintech apps like PayPal and Apple Pay already have around million users each.
There been quite a debate and discussion over the POW mechanism which is said to be a major cause of network congestion due to mining centralization. Daniel Larimer, author of Delegated Proof-of-Stake Whitepaper has long argued that the miner community controls the block time in order to maximize their interests.
This will ultimately result in all POW systems being controlled by the fiat systems. With the DPOS mechanism in place, all the token holders get a voting right which prevents any one particular group to get control of the system. However, on its official website, one can see that the team has collaborated and received support from many exchanges like BTCC, Huobi, OKex, gate.
This trend started from the generation of the first Bitcoin derivative ï¿½ Bitcoin Cash ï¿½ resulted from the first hardfork in the Bitcoin blockchain. Bitcoin Cash is ranked within the top 3 cryptocurrencies by market cap as per the data available from CoinMarketCap. The arrival of Forkgen has made it further easy for anyone to create their own fork coin just with a click of few buttons.
Forkgen has created a very user-friendly website on which users just need to enter parameters and some other parameters to create their own Bitcoin offshoot. One of the pseudonymous developers behind the creation of Forkgen said that they aim to democratize the process of creating of Bitcoin forks. Forkgen creates a level playing field where anyone can easily create working forks. Then it reduces to a much simpler problem of marketing your new altcoin.
