An ambitious attempt to create a trustless version of Bitcoin for use on the Ethereum network has failed after just two days. Developer Matt Luongo announced he was pulling the plug on tBTC today on Twitter, adding that he will soon release a post-mortem on what went wrong.
“tBTC lasted on mainnet two days. Alas, it was born before it's time. Goodnight, sweet prince,” tweeted Luongo, adding, “We've pulled the red lever, pausing deposits for the next 10 days, and are helping users drain funds. We'll publish a full post-mortem when confirmed... and we will rise again.”

Tokenized versions of Bitcoin are ways of bringing the world’s number one cryptocurrency and making it usable on the Ethereum network. The tokenized form of Bitcoin can then be used in decentralized finance apps and within other decentralized apps.
tBTC is one form of tokenized Bitcoin. It uses smart contracts to lock up a certain amount of Bitcoin, and unlock a tokenized version of Bitcoin—of the same amount—on the Ethereum network.
According to data from BTConEthereum.com, a total of 7.13 Bitcoin, or roughly $68,000, is locked up in tBTC at time of writing. This is peanuts compared to the more well-known Wrapped Bitcoin (WBTC) project, which has 2,296 Bitcoin locked up, worth $22 million. But it’s not bad for its first two days.
Unlike Wrapped Bitcoin, tBTC was designed to be more decentralized. While Wrapped Bitcoin depends on several companies in the crypto space to oversee the whole operation, tBTC had no such dependencies. But, by relying fully on smart contracts, its code had to be faultless. And this is likely where things went wrong.
Bitcoin is the world’s first, largest, and most-recognized crypto asset. Since Bitcoin’s creation over a decade ago, the technology behind the revolutionary “peer-to-peer electronic cash system” has largely remained the same. But Bitcoin isn't the be-all and end-all of cryptocurrency. On smart contract blockchains such as Ethereum, developers have created a thriving decentralized finance (DeFi) ecosystem. In order to use Bitcoin within Ethereum's DeFi ecosystem, it's necessary to create an ERC-...
“TL;DR on what happened?” asked Anthony Sassano, product marketing manager at Set Protocol. “Smart contracts are very hard,” replied designer Richard Burton.

Smart contract bugs can have devastating impacts. In one instance, just a few lines of code broke The DAO, an organization built on the blockchain, which hoped to distribute funding to projects. It lost 3.6 million Ethereum, worth $50 million at the time.
And they’re surprisingly common. A report in August 2019 found that 25% of all smart contracts contained serious bugs and 60% of all projects looked at had at least one security issue, according to Bitcoin.com.
With the bug in mind, stopping the tBTC project should reduce the risk of anyone losing money. But that developers were able to stop it raises questions over how decentralized it really was to begin with.
Researchers at the University of Texas at Austin have figured out how to turn everyday throwaways into a technology that pulls clean water straight from the atmosphere. The team used different organic materials to develop "molecularly functionalized biomass hydrogels" that extract drinkable water from air using only mild heat, producing nearly four gallons daily per kilogram of material—about three times more than typical water-harvesting technologies. "This opens up an entirely new way to think...
MetaMask is rolling out support for Solana and Bitcoin this year, a move that will allow the Ethereum-centric crypto wallet to cast a wider net for new users. Beginning in May, MetaMask will enable its users to buy, sell and swap tokens and interact with decentralized applications across the Solana ecosystem, the company said Thursday in a statement. The application will also begin supporting Bitcoin sometime between July and September, allowing MetaMask users to hold the world's oldest cryptoc...
Ethereum founder Vitalik Buterin has called for "truly robust wallet solutions" that reduce the risk of accidental crypto losses. While much attention has been paid to crypto hacks of late, with more than $1.4 billion recently stolen from crypto exchange Bybit, Buterin argued that not enough attention is paid to helping those whose digital assets have become inaccessible. "Software bug, forgotten password, lost device, paper wallet burned down in LA fire, upgraded device without backing up data...
