True that. 1. The bitcoin network uses quite a huge amount of electricity. But this is really not 'wasted' since its the price to pay for securing the bitcoin network. 2. Not all Blockchain networks require excessive electricity/mining. There are other puzzle-based challenges that require less electric power and Ethereum with its 'Proof-of-Stake' instead of 'Proof-of-work' puzzle comes to mind. Infact 'private' Blockchain solutions are not that much energy hungry - though that brings in a certain level of insecurity that must be accounted for. 3. Most crypto-thefts are happening 'off' the Blockchain, that is at the user or crypt-currency exchanges levels. Its like losing your password and subsequently your money getting lost. More awareness needed at that level. walu.

Country X does not trust that their voting platform will not be compromised when results start trickling in, so the results better be written real time on Ethereum blockhain where a transaction cannot be modified once written on a block. University X does not trust their employees to maintain a genuine database of graduates, and therefore they write the list of graduates on a public blockchain. The nodes on public blockchains have to be decentralised and run by multiple entities, to approve transactions, to validate other nodes, and above all to avoid 50%+1 attack. There are centralised blockchain solutions with zero mining like Ripple network. It's controlled by one organisation, and all their tokens are pretty mined. Those too solve some problems in their niche market. @Ali, @Victor, it's not a design flow that transactions cannot be reversed. It is by design, because that is what is trying to be achieved in the first place. But reversal is actually possible, and that is what some soft and hard forks have done. A popular reversal was the DAO hack in 2017, Ethereum did a fork and reversed the hack. Only that the reversals are costly because there is not supposed to be any.

The energy used in “mining a currency” provides no value at all, but is calculating sums for no reason other than to control supply of such currencies. It’s not to say that banks, data centers or ATMs should not be more energy efficient, but it is important to question why a process is designed to waste resources.

Coincheck suspended deposits and withdrawals for all crypto-currencies except Bitcoin as it assessed its losses in NEM, a lesser-known coin. If the theft is confirmed, it will be the largest involving digital currency. Another Tokyo exchange, MtGox, collapsed in 2014 after admitting that $400m had been stolen from its network.
