New Cryptocurrency Developed by MIT Researchers is Way More Faster, Efficient

The researchers built their system on top of a new cryptocurrency network called Algorand, which is secure, decentralised, and more scalable than other cryptocurrencies

MIT researchers have developed a new cryptocurrency that drastically reduces the data users need to join the network and verify transactions by up to 99 per cent compared to the current popular cryptocurrencies.

Cryptocurrencies, such as the popular Bitcoin, are networks built on the blockchain, a financial ledger formatted in a sequence of individual blocks, each containing transaction data.

To join a cryptocurrency, new users must download and store all transaction data from hundreds of thousands of individual blocks. They must also store these data to use the service and help verify transactions. This makes the process slow or computationally impractical for some.

In a paper to be presented at the forthcoming Network and Distributed System Security Symposium, the researchers introduced Vault — a cryptocurrency that lets users join the network by downloading only a fraction of the total transaction data.

It also incorporates techniques that delete empty accounts that take up space, and enables verifications using only the most recent transaction data that are divided and shared across the network, minimising an individual user’s data storage and processing requirements.

“The paper title is a pun. A vault is a place where you can store money, but the blockchain also lets you ‘vault’ over blocks when joining a network,” said Derek Leung, a graduate student in the Computer Science and Artificial Intelligence Laboratory (CSAIL) at the MIT.

“When I’m bootstrapping, I only need a block from way in the past to verify a block way in the future. I can skip over all blocks in between, which saves us a lot of bandwidth.”

In experiments, Vault reduced the bandwidth for joining its network by 99 per cent when compared to Bitcoin and 90 per cent when compared to Ethereum, which is considered one of today’s most efficient cryptocurrencies.

Importantly, Vault still ensures that all nodes validate all transactions, providing tight security equal to its existing counterparts.

As Bitcoin Turns 10, Its Investors Face Year-On-Year Loss

Investors who bet early on bitcoin and have stuck with it have faced a roller-coaster ride in its first decade.

Bitcoin was heading towards a year-on-year loss on Wednesday, its 10th birthday, the first loss since last year’s bull market, when the original and biggest digital coin muscled its way to worldwide attention with months of frenzied buying.

By 1300 GMT, bitcoin was trading at $6,263 on the BitStamp exchange, leaving investors who had bought it on Halloween 2017 facing yearly losses of nearly 3 percent.

A year ago, bitcoin closed at $6,443.22 as it tore towards a record high of near $20,000, hit in December.

That run, fueled by frenzied buying by retail investors from South Korea to the United States, pushed bitcoin to calendar-year gains of over 1,300 percent.

Ten years ago, Satoshi Nakamoto, bitcoin’s still-unidentified founder, released a white paper detailing the need for an online currency that could be used for payments without the involvement of a third party, such as a bank.

Traders and market participants said the Halloween milestone was inevitable, given losses of around 70 percent from bitcoin’s peak and the continuing but incomplete shift towards investment by mainstream financial firms.

“The value mechanisms of crypto and bitcoin today are based more on underlying tech than hype and FOMO (fear of missing out),” said Josh Bramley, head trader at crypto wealth management firm Blockstars.

Growing use of blockchain – the distributed ledger technology that underpins bitcoin – is now powering valuations of the digital currency, he said, cautioning that some expectations for widespread use have not yet materialized.

Others said improvements to infrastructure such as custody services may allow mainstream investors who are wary of buying bitcoin to take positions.

“We see behind closed doors financial and non-financial institutions beavering away to create the infrastructure,” said Ben Sebley, head of brokerage at NKB Group, a blockchain advisory and investment firm.

Bitcoin has endured year-on-year losses before, according to data from CryptoCompare, most recently in 2015.
