Yesterday, we cracked open the tech behind blockchain – the digital pocket book that by no means forgets.
However not all blockchains are constructed the identical. Some are open books, some are locked diaries, and a few are… one thing in between.
Let’s pour them out and see what every one tastes like 👇
1/ Public blockchains – the open ones
These are blockchains anybody can be a part of, use, or confirm.
Each transaction is seen to everybody, and anybody can assist verify it.
That is what makes these chains absolutely decentralized and transparent- no single particular person or firm is in management.
Nonetheless, that openness comes with trade-offs. As a result of each participant should agree on every transaction by way of a consensus course of, confirming transactions takes time. And the extra folks concerned, the longer it could actually take.
On prime of that, customers compete to get their transactions processed first by providing charges to validators or miners. When demand is excessive, these charges improve.
Examples:Bitcoin, Ethereum, Solana.
✅ Execs: Open, safe, censorship-resistant.
⚠️ Cons: Slower and typically expensive.
Consider public blockchains like a public park: anybody can stroll in, everybody enjoys it – however it could actually get crowded.

2/ Personal Blockchains – the closed ones
These are the alternative. A single group controls who can be a part of and what they will do.
You want permission to take part, and information is commonly saved personal, which is good for companies that take care of delicate data.
And since solely a restricted variety of trusted contributors validate transactions, these networks can course of information a lot sooner and extra effectively than public ones.
Instance: Hyperledger Material, utilized by IBM and different corporations.
✅ Execs: Quick, environment friendly, personal.
⚠️ Cons: Centralized.
A non-public blockchain is sort of a company workplace constructing: all the things runs easily inside, however you may want an entry badge to get previous the entrance desk.

3/ Consortium or hybrid blockchains – the mix-and-match ones.
These mix parts of each private and non-private techniques.
They’re typically run by a gaggle of organizations that share management – or they mix public transparency with personal permissions.
Examples: R3 Corda, Power Net Chain, and even components of Ripple’s XRP Ledger.
✅ Execs: Collaboration with some decentralization.
⚠️ Cons: Nonetheless depends on just a few trusted gamers.
Consider consortium chains like a members-only coworking area – shared entry, restricted entry, and everybody inside has pores and skin within the sport.

Anyhow, irrespective of which taste you sip on, the recipe’s the identical at its core:
Each blockchain retains a safe, verifiable report of who did what, and when – the distinction lies in who will get to put in writing within the pocket book.
👉 Public blockchains = everybody’s invited;
👉 Personal blockchains = only some have the pen;
👉 Consortium blockchains = a gaggle takes turns writing.

And in case you loved immediately’s Crypto 101 version, take a look at the earlier ones I’ve written on several types of buying and selling, CEXs vs. DEXs, sizzling vs. chilly wallets, tips on how to spot a coin’s crimson flags, and what dApps are.
Now you are within the know. However take into consideration your mates – they in all probability don’t know. I’m wondering who may repair that… 😃🫵
