Old Meets New: How Backward Compatibility works!
Imagine a Video Game Console 🎮
Let’s say you have an old PlayStation 4 (PS4), and you love playing your favorite games on it. Now, a new PlayStation 5 (PS5) comes out with better graphics and new features, but guess what? You can still play your old PS4 games on the PS5!
That means the new system works with the old games. This is exactly what backward compatibility means onchain!
How This Works onchain
When a blockchain gets an upgrade, it still allows older versions to work without any problems. People who haven’t upgraded can still use the blockchain, and their transactions, apps, and digital assets remain safe.
Example: Bitcoin’s SegWit Upgrade
Bitcoin received an upgrade called Segregated Witness (SegWit), which improved transaction speed and reduced fees. However, even if some users or nodes didn’t upgrade, they could still validate and process transactions, as SegWit was a soft fork and remained backward compatible. 1 reply
