But since we don’t trust that the plasma chain will be around in year (even if it’s the exact same consensus mechanism!), crypto we need to think a little bit outside of the box. Luckily that’s not so difficult, but it’s more complex than it would be on the sidechain. Take, for example, a very long (let’s say 1 year) timelock contract. You could definitely put that contract on a sidechain if you trust that the sidechain will be around in a year. We basically need to make sure that if the consensus mechanism fails, we have a way to move the entire timelock contract back onto Ethereum.
These two blockchains could then talk to each other in a special way that made it possible for assets to move between the two chains. First applied mainly to Bitcoin, the sidechain concept was basically to run another blockchain alongside some other "main" blockchain. The idea of the "sidechain" was first popularized by this paper published in 2014.

This factor would allow them to block new transactions from occurring, as well as changing the order of transactions. To hack Bitcoin
, a group would have to control 51% of the verification power on the network. This method of theft is called a 51% attack. However, a theoretical way exists for Bitcoin to be "hacked," although it is extremely unlikely. They could also send money and then reverse the transaction, otherwise known as double-spending.
Hard forks split the blockchain in 2 parts, the first fork adhering to the old rules and the other using the intended modifications. Neither of these was incredibly successful, and most of the community has remained on the main Bitcoin blockchain. Soft forks generally cause less turbulence in the community and have fewer downsides, but they can’t be used for everything. Soft forks don’t create a new blockchain; they just add a new rule to the old one. Examples of Bitcoin forking include Bitcoin
Cash and Bitcoin SV, both of which massively increased the block size, allowing for faster and cheaper transactions.
If you think about what we just described, there’s really no reason why the person who originally deposited some asset also has to be the same person to withdraw the asset. Even though we might’ve made dozens of transactions on the sidechain, only two transactions (the deposit and the withdrawal) ever occur on Ethereum. This is what makes sidechains so cool – assets can be moved around a lot before they’re withdrawn. Since transactions on the sidechain are almost always cheaper than transactions on Ethereum, we get scalability!
This convenient property also means that the plasma chain can use really simple consensus mechanisms (like just a single authority!) and still be safe. Simply stated, a plasma chain is as secure as the main chain consensus mechanism, whereas as sidechain is only as secure as its own consensus mechanism. Effectively, this means that plasma chains are safer than sidechains by design. Your funds are only ever at risk if Ethereum fails, but you probably have bigger problems.

During the last 24 hours we are experiencing a +0.64% rise. We categorize them based on their daily trend. Bitcoin
dominance is at 39.5%. We use our technical indicators to see the Market Status and analyze our favorite Cryptocurrencies. The Coinrise Trading Report 12 September 2022, the Crypto Market Cap is at 1.062T USD with a 24 Trading Volume of 75B USD. More specifically we monitor 15 Cryptocurrencies.
While the global crypto market cap has crashed in the last few days to just $1.24 trillion and prices of many altcoins have dropped drastically, the dominance of Bitcoin (BTC), the most popular cryptocurrency, seems to be rising.
The irony is that as investments in Bitcoin and other assets become more widespread, they will attract more regulatory scrutiny. Many virtual currency adherents are deeply skeptical of the role governments and central banks play in the financial system.
