After months of delay, Bitcoin layer-2 community Stacks is lastly activating its anticipated Nakamoto improve—a change anticipated to spice up transaction speeds by orders of magnitude.
The improve, which started its activation sequence on Wednesday, will decouple the Stacks community’s block manufacturing from Bitcoin itself. It will enhance block manufacturing by 120 instances, rushing up affirmation instances from Bitcoin’s 10-minute common to mere seconds.
Stacks operators have everything of Stacking cycle 92 to implement the improve, after which core builders will choose the ultimate arduous fork block and the total implementation of Nakamoto consensus guidelines might be in impact. One “Stacking cycle” lasts 2,100 Bitcoin blocks, which takes roughly two weeks.
Amid Wednesday’s code distribution, the worth of its native STX token is down almost 11% over the past 24 hours per knowledge from CoinGecko, sitting at a present value of $1.59. The decline seems to replicate each broader crypto market losses from late Tuesday, plus an extra dip for STX because the announcement was made this morning.
Nakamoto Activation Window Begins 🟧
Right this moment marks the start of a sequence to securely convey the Nakamoto improve and its quick blocks and Bitcoin finality to the Stacks layer!
Have a good time with 21 days of occasions, massive information, collaborations, giveaways, and extra. 🧡

The Nakamoto improve was partially carried out again in April, with the community starting to mock-sign transactions underneath its new proof-of-transfer (POX) contract on the time. POX is the consensus mechanism utilized by Stacks, wherein Stacks “miners” burn BTC (somewhat than electrical energy) to mine Stacks blocks and earn STX rewards.
The activation of the improve was to happen shortly afterward, however core builders determined to delay it for eight weeks to prioritize sure security measures and code audits as an alternative. With Nakamoto’s arrival, Stacks won’t solely be quicker, however builders say that transactions on the community will inherit full Bitcoin finality, turning into as tough to reverse as a Bitcoin transaction.
Nakamoto additionally primes Stacks for the rollout of sBTC, a “programmable Bitcoin asset” that permits customers to bridge their BTC to the Stacks community in a comparatively decentralized manner.
“Nakamoto is already code full, with sBTC anticipated to be code full in September and prepared for launch 4 weeks after Nakamoto is absolutely activated,” mentioned Stacks Basis Govt Director Mitchell Cuevas instructed Decrypt.
Going ahead, a few of Stacks’ priorities will embrace fostering sBTC adoption, interoperability with different blockchains, and rising extra decentralized purposes on the improved system.
The Stacks Basis can even prioritize analysis into BitVM—a computational framework revealed final 12 months that’s birthed a brand new wave of innovation and layer-2 (L2) designs on high of Bitcoin.
“The emergence of different Bitcoin L2s is validation of the long-held imaginative and prescient that Bitcoin can and must be greater than only a retailer of worth,” mentioned Cuevas. “This isn’t a zero-sum sport, and we brazenly collaborate with these attempting to make Bitcoin extra helpful for extra folks.”
That mentioned, Cuevas urges warning to not leap at each new Bitcoin layer-2 community that catches buyers’ consideration.
“That is more durable than it seems to be, and I feel some tasks are discovering that out,” he mentioned. “I encourage customers to analysis rigorously as new Bitcoin L2s pop up—if one thing appears too good to be true, it most likely is.”
