[oseikuf44]

Every aspect of problem facing humanity can be solve on blockchain efficiently. Energy, database management and fair gambling can be solve with blockchain. Bitcoin solve payment system among peers.

[Rockkey]

The most important problem that bitcoin and blocking can solve is the complexity in the execution of transactions and their high cost. Bitcoin and other crypto currency are able to transfer huge amounts of money to any distance for a very small payment. Before the appearance of bitcoin, this was impossible.

I think that there are no limits to the use of Blockchain technology in our world. The same can be said about Bitcoin. These technologies can solve any economic and other problems.

What problems in the world can Bitcoin and blockchain technology solve ?

The blockchain technology can solve many problems. It's a decentralised, immutable, trustless ledger (database)... There are tons of scenario's that pop to mind, basically any scenario where equal partners want to create a database between them, but don't fully trust one partner to run a classical database out of fear this one partner that hosts the db would tamper with the data.

You can use a blockchain database to store insurance information and share it between insurance companies and individuals; univeristy's can use it to store hashes of grades, titles, diploma's, so somebody interviewing for a job can immediately be crosschecked about the diploma's he/she claims to have;... and those are just 2 commonly known examples.

For bitcoin, the blockchain technology solves, amongst other things, the double spending problem. By storing transactions onto a decentral, trustless, immutable ledger, people can not double spend unspent outputs without their transactions getting rejected (given that the first transaction is already included in a block at the time the double spending transaction is broadcasted).

Even the people that hate crypto currencies see the potential behind the blockchain technology

In short, problems that are trust related. Banks startes from escrowing services due to the lack of trust of the people to each other and I can't blame them for that. But now, with the introduction of blockchain and smart contracts, we can now transact online with confidence and assurance that the contract would be implemented

Exactly, it assures both parties have no control over the order to be fulfilled and only the smart contract algorithms will take care of that issue.

Blockchain is helpful in solving problems of Internet-of-things:  
- It solves the problem of your ownership with smart appliances and enables transferability by encrypting these appliances on the blockchain.
- It facilitates Supply Chain Sensors which gives companies end-to-end visibility of their supply chain by providing data on the location and condition of the supplies as they are transported around the globe. The blockchain stores, manages, protects and transfers this smart information.

Bitcoin offers some unique advantages due to its unique nature. With Bitcoin, there is no longer the fear of interruption user transactions or being placed freezes on users' accounts since there's no third parties like banks or other financial authorities.
As for Blockchain, with the timestamp characteristics, it has ability to confirm the existence of something at a stated time that is further provable in a court of law.

As far as I know, Blockchain may be used to facilitate digital voting in the future because of its high security, which is needed for online voting. Using the blockchain, a voter could check that her or his vote was successfully transmitted while remaining anonymous to the rest of the world.
As for Bitcoin, it makes transaction simpler, faster, cheaper, and more convenient.

Online voting for national elections should be the top priority after cashless society. Blockchain provides all the security that is excellent.

[Shiro21]

I think if you can use it well bitcoin can be a weapon that can solve your problems because all the problems in the world are dominantly rooted in money. people are fighting for money, people are married for money, and all power must require money.
The conclusion is that bitcoin and blockchain can solve your main problem of money.

Crypto currency is also able to solve the problems associated with electronic payments: fraud, the presence of mandatory confirmation by banks, the conversion of currencies and the payment of a share for the transaction. In addition, now there is no need for a guarantor, which will confirm the financial viability of the participants in the transaction.

a way to protect the exchange of information, money, or capacity. bitcoin is only a special case of value exchange

[aray80]

A digital asset known as blockchain-based cryptocurency to manage ledgers that have absolute control for all users .. so all transactions will be easier, safer and transparent.

blockchains (e.g., those used by bitcoin or ethereum) enable two people or organizations to confidently and securely transfer value (e.g., money or a digital asset) electronically from one person or organization to another without an intermediary (e.g., a bank or PayPal).

a side note, technically, the blockchain solved the Byzantine Generals’ Problem, but since the question asked for problems it “generalizably” solves, this is very simple, non-technical answer.

They solve the age-old problem of financial slavery. From which derive all other slavery.

Blockchain can solve a whole range of problem if integrated into our everyday lives. For the figures and values on the blockchain network cannot be altered.
Should it be applied for procurement in public offices, it will wipe out coruption, I hope it can find its way to Nigeria's politcical election so as to avoid electoral practices and bailout box hijacking.

Bitcoin and blockchain solve the problem of discrimination because of blockchain there is equality in all transactions, no identity revealed whether rich or poor, fair is equally distributed. It also reduces unemployment and contributes higher economical status. Bitcoin gives hope to those who suffered from financial stress crises.

[BorisVirla]

Just imagine that in the world all databases will work through the block.  This is an instant response to all the questions of interest in education, health care and others.

[billygarrison]

bitcoin and blockchain can be an alternative to inter-money transfers quickly, practically, and do not need to go to the western union to send money,

bitcoin and blockchain can eliminate corruption problems in my country if my president accepts bitcoin as legitimate money

and there are still many problems that can be solved with bitcoin and blockchain.

[aleksnutis]

What problems in the world can Bitcoin and blockchain technology solve ?

All problems of centralization.
I most like the possibility of money transfers quickly and without intermediaries.
But while bitcoin has such a voluntariness and lack of convenient services for cashing, this advantage is fully impossible.

[Ayomiqueen]

Blockchain and bitcoin have solved so many problems and will solve more in near future, blockchain is a solution provider to the world by decentralizing everything that has to do with human and most especially financial aspect and keeping real data that can be utter once the node is generated,which every one can verify at any giving time.
