The rollout of the Polkadot protocol has been ongoing since August, when the project launched its Rococo testnet.

Kusama, sister chain to Polkadot’s platform, is ready for the rollout of parachains on the network.

Polkadot and Kusama creator Gavin Wood today said in a blog post that Polkadot was entering the fourth and final phase of its mainnet launch, which involves deploying parachains to the Kusama network. According to Wood, the development arm behind Polkadot, Parity Technologies, had released an upgrade — Polkadot version 0.9 — for Kusama, which “is now finally ready to host parachains.”

Wood said the launch of the parachains would proceed following a full external audit on the new version of Polkadot and Kusama executing “at least one successful auction involving crowdloans and hosting at least one functional parachain” in the wild. He did not provide a specific timeline, but added he expected the audit to be completed “in the near future,” with the Kusama website announcing the first of five auctions one week in advance.

“After Kusama’s first auctions complete successfully, one would expect Polkadot’s auctions to happen soon after,” said Wood.

The rollout of the Polkadot protocol has been ongoing since August, when the project launched its Rococo testnet to evaluate its planned sharding implementation based on parachains. Some expected the rollout of parachains to occur in the first quarter of 2021, but there were reportedly issues with the Rococo testnet’s stability — for example, one of its parachains was apparently stuck for more than a day.

At the time of publication, the price of Polkadot’s DOT token is $39.51, having fallen more than 2.2% in the last 24 hours.

Users of the popular exchange can now access their cryptocurrency DApps directly through the Google Chrome browser.

Digital currency exchange Coinbase has announced a new browser extension for its native wallet, enabling users to more easily connect to decentralized applications and decentralized finance directly on their desktop. 

The Coinbase Wallet browser extension is now available on Google Chrome, the company announced Monday. Coinbase Wallet lead Sid Coelho-Prabhu said that more than 1 million Coinbase Wallet customers regularly connect to applications like Uniswap and Compound. The new Chrome extension will streamline this process, removing the need to scan a QR code on their mobile devices each time they want to connect.

Coelho-Prabhu explained:

“Starting today, we’re making it much simpler to access and use these dapps on desktop with the Coinbase Wallet extension. The new extension allows for instant access to dapps on desktop — after linking your Wallet account to the extension once, you are free to browse all dapps with one click.”

The new extension also supports users trading on decentralized exchanges and collecting nonfungible tokens, or NFTs. Decentralized applications like Rarible, OpenSea, SushiSwap, Matcha, Synthetic and Aave, among many others, are also supported.

Coinbase is one of the world’s largest cryptocurrency exchanges, with its Coinbase Pro platform processing nearly $10.6 billion in transactions in the last 24 hours, according to CoinGecko data. Only Binance handles more volume.

Coinbase also became the first major cryptocurrency exchange to file for a public offering. The company’s COIN shares hit the Nasdaq in mid-April. Like many other newly listed stocks, COIN has experienced extreme volatility in its short trading history, having only recently fallen below the $250 pre-listing reference price.

Joining the Paxos Settlement Service could allow many Bank of America customers to settle stock trades in minutes rather than days.

The second-largest bank in the United States is now reportedly using blockchain technology for settling stock trades.

According to a Bloomberg report on Monday, Bank of America has joined Paxos Settlement Service, a platform capable of same-day settlement of stock trades using blockchain technology. Kevin McCarthy, head of financing and clearing, said the bank “has been conducting internal transactions for the past few months” and would offer the service to Bank of America clients upon approval as a clearing agency.

The move would reportedly allow for a “more flexible and speedier” stock settlement system compared with that of the Depository Trust & Clearing Corporation, or DTCC, in which Bank of America is a direct participant. The DTCC settlement time is roughly two days, whereas Paxos’ service is capable of settling some stock trades in minutes.

“We can determine the settlement cycle down to T+0,” said McCarthy. “We then can free up the collateral we’d have to post on an overnight basis. […] The return-on-assets in this business would improve, which has been a challenge.”

Paxos officially launched its settlement service for equity trades in 2019 after receiving no-action relief from the U.S. Securities and Exchange Commission. Credit Suisse, a Zurich-based financial institution, and Instinet, the trading arm of Nomura Holdings, both participated in the pilot, settling U.S.-listed stock trades on the same day.

The stablecoin operator announced in April that it had applied for a clearing agency license with the SEC. Paxos also recently completed a $300-million funding round, which brought its valuation to $2.4 billion.

COIN, MARA, RIOT and other blockchain-related stocks continue to slide as Bitcoin struggles to hold above $43,000.

It is well known that as goes Bitcoin (BTC), so goes the rest of the cryptocurrency market, as time and again, major price moves from Bitcoin create ripples across the altcoin market, impacting sentiment and momentum.

This appears to be the same for blockchain-related stocks that trade in the traditional financial markets, and a quick glance at the charts shows they have mirrored Bitcoin’s performance over the past several months. 

The cryptocurrency ecosystem was all abuzz just over one month ago when the much anticipated Coinbase stock listing finally arrived on April 14, a date that also marks the most recent all-time high in the price of BTC at $64,863.

Since its debut, the price of COIN has steadily declined below both its direct listing price of $381 and its reference price of $250 to a current value of $245, coinciding with a roughly 35% drop in the price of BTC, which has also put pressures on other blockchain-related stocks including Riot Blockchain and Marathon Digital Holdings.

COIN’s struggles since launching, which have resulted in its valuation dropping from a high of $100 billion to its current valuation of $49 billion, have centered around concerns about whether or not the exchange will be able to achieve future profit expectations in the face of an increasingly competitive landscape, with new centralized and decentralized players emerging weekly and looking for a piece of the action.

Matthew Wheeler, global head of market research at Forex.com, recently highlighted the increasingly competitive landscape Coinbase now faces as cryptocurrency adoption increases on a global scale. 

“While Coinbase has been able to rely on its first mover advantage and brand familiarity so far, margins will continue to compress from competition with both ‘CeFi’ brokerages like BlockFi and ‘DeFi’ alternatives like Uniswap.”

These concerns have led some analysts, including New Constructs CEO David Trainer, to warn that the price of COIN could fall below $100: 

“Investors should expect the stock to continue to underperform, as shares could fall to $100 or less as it becomes clear the company is unlikely to meet the future profit expectations baked into the stock price.”

Bitcoin sell-off spreads

While the struggles faced by COIN can be chalked up to it being a newly listed stock that is still looking to establish its fair market value, downtrends in Riot Blockchain and Marathon Digital Holdings, which had both outperformed BTC in 2021, also demonstrate the effect that a struggling BTC price has on crypto-related stocks.

A survey of the wider financial markets indicates that the overall tech sector pullback and concerns related to rising inflation have further hampered price growth in blockchain-related stocks, and there are few signs that these pressures will resolve in the near term.

The prices of both RIOT and MARA have followed Bitcoin price movements since the 2017–2018 bull market, so it is likely that further price growth for these and other blockchain-related stocks will depend on how BTC performs going forward.

It is curious to note that the price of RIOT and MARA rallied ahead of Bitcoin in 2021 to reach new all-time highs, indicating the possibility that they could be used as a leading indicator for future price movements for BTC and altcoins while offering traditional market investors exposure to the asset class without having to hold cryptocurrencies directly.

However, depending on how the market plays out moving forward, it should be noted that Bitcoin remains the dominant market indicator for all things blockchain- and cryptocurrency-related — meaning as goes BTC, so goes the rest of the market.
