Bitcoin Vs Blockchain

By gud Post a Comment
In the recent months in that location has been a lot of buzz inwards the fiscal globe nearly the "can become yesteryear without them through other means.

"Centralized blockchain is simply a database"


While inwards the previous department nosotros touched on the economic science of running a centralized blockchain, hither nosotros volition locomote discussing what is the indicate of running a centralized blockchain inwards the offset place.

There are many reasons to connect to a decentralized blockchain similar Bitcoin - you lot tin transact alongside anyone inwards the world, nobody tin ban you lot from the network in addition to all your transactions are forever stored in addition to distributed amidst many computers all simply about the world. However, in that location are also some needs that can't locomote achieved inwards a world ledger - protection of someone data, mo transaction speed, dealing alongside exclusively known parties, etc. All of those are features needed yesteryear some companies - perhaps they postulate to follow strict KYC rules on all clients, or they are dealing alongside sensitive fiscal information that postulate to locomote kept private. One way or the other - in that location are some valid reasons to run a someone blockchain.

Given all that, what advantages in addition to disadvantages are in that location to using a blockchain over a database?

There are for certain many disadvantages - since the blockchain is a novel technology, it mightiness non locomote equally optimized equally a database. If we're talking nearly a distributed network, in that location is also a lot of delay when the information is transmitted, non to cite the block creation fourth dimension itself.

There are also some advantages to a blockchain over a database:
  • The entire condition of the organisation tin locomote summarized inwards a unmarried hash (latest blockchain hash)
  • Every total node inwards the organisation is synchronized alongside the residual of the network in addition to volition give consistency alongside it
  • Every transaction is authorized yesteryear a someone key, pregnant every activity in addition to instrumentalist tin locomote held accountable
  • Every block tin locomote similarly authorized yesteryear a known entity / someone key, pregnant that whatever "51% attacks" tin locomote traced in addition to punished externally
  • There is certainty for whether or non a transaction committed successfully to the blockchain in addition to what is its outcome (especially if we're talking nearly to a greater extent than complex systems similar Ripple or Ethereum)
While in that location mightiness locomote piffling purpose for a blockchain engineering scientific discipline if it's used yesteryear a unmarried entity, it for certain convey upwards a lot of benefits if we're considering multiple parties using the blockchain engineering scientific discipline to comport business:
  • All transactions on the network tin locomote legally binding equally per understanding (especially if we're talking nearly making concern decisions using smart contracts or tracking debt using a Ripple-like ledger)
  • There is no confusion equally to the electrical flow Earth of the network - everyone volition locomote on the same page i time fully synchronized
  • Given the block creators are trusted entities (in a model similar to native coins that render an incentive for the miners to locomote creating to a greater extent than blocks, things become a fleck to a greater extent than complicated.

In a traditional blockchain similar Bitcoin, the native currency is non exclusively used to incentivise the miners, but also to forbid spam. It is quite an elegant solution - anyone wishing to mail a payment won't heed spending less than a penny to become their transaction included inwards a block, but someone flooding the network alongside spam transactions volition experience the burden of the fees compounding on them.

H5N1 blockchain without an internal currency loses both the incentive for the miners to create novel blocks in addition to forbid spam through the purpose of fees. While this would likely cripple whatever decentralized blockchain, it mightiness non locomote the example alongside to a greater extent than centralized blockchains (we'll hash out them inwards particular afterwards on).

The miners tin locomote subsidized inwards other fashion, or fifty-fifty ran for costless yesteryear the businesses that rely on the network. This is the example alongside can become yesteryear without them through other means.

  • There is no confusion equally to the electrical flow Earth of the network - everyone volition locomote on the same page i time fully synchronized
  • Given the block creators are trusted entities (in a model similar to Ripple's validators - most of them are run yesteryear Ripple Labs, since they cause got a strong stake to proceed the network running, but i could imagine a to a greater extent than decentralized network alongside validators beingness run yesteryear the diverse gateways on the network. Since the validators earn money inwards some other way (running gateways, providing other services, etc.), it makes feel to proceed the servers running.

If we're talking nearly blockchains without fees, Hyperledger and Eris come upwards to mind. While those solutions don't appear to locomote suitable for decentralized networks, they brand feel if we're talking nearly a finite number of known servers communicating alongside i another. In this scenario, similar to a someone network, you lot don't await spam or DOS attacks to locomote an number - all the parties are known in addition to they cause got no motivation to fix on the network. Moreover, if the users of the network are known, they tin locomote punished if they endeavor to pause the network - either yesteryear having their access revoked, or maybe yesteryear some legal actions beingness taken against them. 

So all inwards all, it looks similar decentralized networks practise postulate a token to run their blockchain, spell to a greater extent than centralized solutions can become yesteryear without them through other means.

  • Audits of the network are unambiguous, since all transactions are world (provided the auditor has access to the total blockchain)

Centralized versus decentralized blockchains


While centralized blockchains cause got their uses, in that location are for certain some advantages to using a decentralized blockchain (Bitcoin or otherwise).

First of all, anything that happens on a large, decentralized blockchain such equally Bitcoin tin locomote verified to cause got happened at the given time. Centralized blockchains tin locomote re-written or forged if all the involved parties collude, spell a decentralized blockchain is much harder to corrupt. This is why nosotros encounter companies similar Factom using the Bitcoin blockchain for timestamping - the tape is world in addition to provably immutable. Any someone blockchain wishing to testify their records were non altered would similarly cause got to purpose the Bitcoin blockchain in addition to embed the block hashes into it to testify the information was non altered afterwards downward the line.

Secondly, it may locomote much easier for multiple companies to concur to purpose can become yesteryear without them through other means.

  • There is certainty for whether or non a transaction committed successfully to the blockchain in addition to what is its outcome (especially if we're talking nearly to a greater extent than complex systems similar Ripple or Ethereum)

  • Given the block creators are trusted entities (in a model similar to a decentralized network equally a middleware, rather than them agreeing to purpose a proprietary blockchain. This is specially truthful if nosotros would locomote talking nearly companies dealing alongside entities they don't know or don't trust. Using a decentralized network allows you lot to tap into its network resultant - you're non exclusively connected to a few parties, but to potentially everyone inwards the world.

Conclusions


All inwards all, in that location are advantages in addition to disadvantages to both using centralized in addition to decentralized blockchains. Every i of them is a tool of its own, in addition to some mightiness locomote to a greater extent than suitable for problems than others. While the Bitcoin network for certain has a lot of value on its own, it's non a silvery bullet solution to all problems in addition to purpose cases. Blockchain without Bitcoin is for certain possible, but fifty-fifty inwards the globe filled alongside centralized blockchains, Bitcoin has a house of its own.
