Bitcoin Taproot upgrade finally locked-in, activation set for November

With Taproot achieving the 90% critical consensus mark among mining nodes, all is now set for Bitcoin soft fork activation later in November.

The Taproot upgrade has achieved the first significant milestone on the road to activation as 90% of the Bitcoin (BTC) mining hash rate signaled for the protocol improvement within the current difficulty epoch.

Data from Taproot.watch, a webpage created by Bitcoin developer Hampus Sjöberg, shows the lock-in stage is now completed.

All recognized mining pools signaled for the upgrade with Slush Pool being the first to do so. It is perhaps fitting that Slush Pool also mined block 687285 that sealed the Taproot lock-in.

AntPool and F2Pool — the top two Bitcoin mining pools by hash rate share — were also among one of the earliest supporters of the Taproot activation in the BTC mining arena

In a conversation with Cointelegraph Bitcoin core developer Pieter Wuille explained the activation step for Taproot, stating: “According to BIP341, once locked in, activation is automatic at block height 709632 - expected around November 14, 2021.”

Wuille also commented on the significance of Taproot, adding:

“It's the first consensus change since Segwit activated in august 2017. It extends Bitcoin's script capabilities in ways that make certain things cheaper (especially more complex applications like multisig and layer 2 things), and somewhat more private by often hiding what the exact spending rules were.”

According to Wuille, the activation in November is only the beginning as the real work will be building the software to leverage the benefits of the protocol improvement.

June 12’s historic significance for Bitcoin has also moved beyond Taproot as the day seen a record number of transactions mined in a single block. Data from blockchain explorer Blockchair shows 4,075 transactions in block height 687249.

This record figure is almost twice the average transactions per block recorded on June 11 and is four times the typical transaction count for Bitcoin blocks.

With hash rate declining amid mining restrictions in China, Saturday’s transaction count average might be due to a slowdown in block production forcing more transactions to be included in a single block.

Vitalik Buterin Says People Difficulties Not Technical Difficulties Slowed the Ethereum 2.0 Rollout

Vitalik Buterin Says People Difficulties Not Technical Difficulties Slowed the Ethereum 2.0 RolloutThe cofounder of Ethereum, Vitalik Buterin, recently discussed the highly anticipated full transition from a proof-of-work (PoW) consensus model to proof-of-stake (PoS) as its replacement. Buterin admitted at Hong Kong’s Startmeup HK 2021 Festival that the transition was taking too long and highlighted that it wasn’t technical problems but “related to people.” Buterin: ‘If You […]

Vitalik argues that proof-of-stake is a ‘solution’ to Ethereum’s environmental woes

The stakes are high for the chain to transition, as those that don't risk getting 'left behind.'

At a conference yesterday, Ethereum co-founder and unofficial figurehead Vitalik Buterin argued that Ethereum’s upcoming transition to a proof-of-stake consensus mechanism is a “solution” to the blockchain’s rampant energy consumption that has been incensing critics as of late.

In an interview at the StartmeupHK virtual conference hosted from Hong Kong, Buterin said that while proof of stake is “still in its infancy and less battle-tested” than Ethereum’s current proof-of-work model, it can ultimately reduce the chain’s energy consumption by upwards of 10,000x.

The comments come amid a period of rampant criticism of blockchain technology for its ecological impact — including from some erstwhile supporters. Tesla founder Elon Musk recently undertook an about-face in regards to the car company accepting Bitcoin payments, saying that he could not encourage the use of fossil fuels via Bitcoin mining. In other threads, he also called for Dogecoin to increase its efficiency across several key metrics.

Buterin directly responded to these comments about scalability in a blog post on his website, laying out the problems with trying to scale by simply tweaking the parameters around blocksize.

Earlier in the month, Buterin also argued that Bitcoin’s continued use of proof-of-work means that the chain, which is currently the world’s largest, will eventually get “left behind” as users increasingly demand more energy-efficient and environmentally friendly options — a phenomenon he says makes it “possible” that Ethereum eventually eclipses Bitcoin and the largest digital asset. 

Ultimately, Buterin seems to agree with critics regarding the need for blockchains to adopt newer, more efficient models  — especially as the chain grows in volume and becomes a widely relied-upon computational network.

"This thing we’re building isn’t just a game anymore. It’s a significant part of a new era.”

Ripple’s Chris Larsen Believes Bitcoin Dominance Could Fall Over Proof-of-Work’s Energy Consumption

Ripple’s Chris Larsen Believes Bitcoin Dominance Could Fall Over Proof-of-Work’s Energy ConsumptionRipple Labs cofounder Chris Larsen has a bone to pick with bitcoin and crypto networks that leverage proof-of-work (PoW). Larsen’s latest write-up explains that the crypto industry needs to reconsider PoW because of the effects on the environment. The Ripple executive believes that other types of consensus algorithms have been effective at being secure while […]
