Early in 2015, Vitalik Buterin and others unveiled Ethereum, a new decentralized blockchain that enhanced the capabilities of bitcoin by enabling the execution of smart contracts and other applications. While cryptocurrency wallets provide security and a firm foundation, users can collect and raise crypto kittens, own digital art, lend coins, and do much more.

The Development of Physical Wallets

Using cold wallets or internet-free storage techniques like paper, CDs, or USBs, is one way to prevent theft and loss. These wallets are used for bitcoin addresses that have sizable storage but are not currently being actively used for transactions. These wallets guard against hackers acquiring your secret keys, but they are not impervious to external factors like fires, coffee spills, or unintentional disposal. The Welshman who, in 2013, threw away a hard drive with bitcoin keys valued at more than $500 million was impacted by the latter conduct.

The security offered by hardware wallets, on the other hand, is provided by the ability to carry out transactions without disclosing your private keys to a computer. Trezor One, a hardware wallet with roots in the Czech Republic, offered customers a physical USB attachment that added an additional layer of authentication. It featured a password manager, two-factor authentication, and a computer interface for entering passphrases.

The Development of Decidistic Wallets

Utilizing hierarchical deterministic (HD) wallets was a different approach. These wallets employ a known deterministic technique to produce a series of cryptographic key pairs from an initial seed number. In order to restore the original keypairs, if we lose the keys to the addresses, we only need to feed the algorithm the same seed value.

Users might encrypt their bitcoin wallets and generate deterministic keys with Electrum, an open-source, lightweight bitcoin wallet. The 128-bit seed number, which is created randomly, can be converted into mnemonic code made up of 12 random English phrases. Wallets featuring this functionality were known as brain wallets. BIP 39, which had 2048 distinct phrases to use for seed phrase creation, was suggested in September 2013.

The developers of MultiBit introduced a new client in May 2014 called MultiBit HD wallet, which supported multi-signature capabilities, deterministic wallet key pair generation, and compatibility with the well-liked hardware wallet Trezor. Due to the company’s “limited resources for development,” some features that were deemed cutting-edge at the time, like stealth addresses and CoinJoin—which were used in the rival product Dark Wallet—were not given priority in the release.

Since they were open-sourced, accessible, and created by developers in their spare time, many of the early wallets, like Electrum, MultiBit, and others, were targeted at programmers, bitcoin enthusiasts, and early adopters. However, when the cryptocurrency user base expanded quickly, it put a strain on a comparatively stable number of developers. In 2013, MultiBit started levying transaction fees equating to a penny. With other wallets, users may select the fee, with greater payments increasing the likelihood that their transactions would be added to the blockchain.

The VCs Retaliate

As venture capitalists started to spend millions of dollars on promising cryptocurrency start-ups starting in 2013, the landscape of crypto wallets started to change. Midway through 2013, Coinbase, which had 121,000 members and generated $1.5 million in revenue at the time, got $5 million in capital to expand the reach of its merchant and online wallet services.

BitInstant, a website for exchanging bitcoins, received $1.5 million in seed funding from Winklevoss Capital Management in the same month. By year’s end, venture capitalists had invested more than $88 million in bitcoin startups, 40 times more than in 2012.

These more recent wallets competed with the older free and open-source solutions, and bitcoin veterans protested that their holdings were subject to the security architecture of centralized corporations. However, the infusion of venture capital funds made it possible for many non-programmers to trade in the cryptocurrency market and established bitcoin as a potential good. As a result, the price of bitcoin shot up dramatically from $12 in November 2012 to $1200 in November 2013.

However, the bull run was short-lived. The biggest bitcoin exchange operator, Mt. Gox, was apparently compromised in February 2014 and lost 850,000 bitcoins. Such a significant heist prompted existential concerns about bitcoin, reduced market liquidity, and sent the price tumbling to roughly $450 by May 2014.

Although bitcoin prices gradually decreased over the following few months, venture capitalists (VCs) funding significantly increased throughout the year because they ignored short-term price fluctuations and concentrated on the technology’s long-term potential as it upended the established financial system. Xapo secured $20 million in investment in August to construct “ultra-secure” physical bitcoin cold storage vaults equipped with biometric scanners and round-the-clock security. A few months later, web3 wallet development maker Blockchain raised $30.5 million, making it the highest bitcoin capital investment of the year. According to data from CoinDesk, VCs had invested 314.7 million dollars by year’s end.
