The Ghost in the Protocol [EPUB ebook] 

Beneath the shimmering steel and glass of Singapore, a digital phantom haunts the halls of Crypto Con, leaving a chilling trail of bodies marked not with messages, but with blockchain addresses – gateways to impossibly altered wallets.  This isn’t hacking; it’s a surgical violation of the blockchain itself, a feat once considered mathematically impossible. The Ghost in the Protocol has arrived.
Amanda Ferrell, a blockchain forensics expert whose career was shattered by a past security breach, is drawn into the investigation, compelled by the Ghost’s audacity and the terrifying implication that the foundations of cryptocurrency are fatally flawed.  Haunted by the ghosts of her past, she must confront her own fallibility in a world she thought she could control.
Partnering with Timothy Hammond, a world-weary Singaporean detective haunted by the disappearance of his brother into the city’s digital underworld, Amanda plunges into a world of decentralized finance, where fortunes vanish in the blink of an eye. Each victim, a key player in Project Chimera, a revolutionary financial system, whispers a cryptic clue from beyond the grave.  Is Chimera a utopian ideal or a devastating secret?
From opulent penthouses to vibrant hawker centers, their investigation unveils a conspiracy reaching far beyond the volatile crypto market.  Jeffrey Gonzalez, a reclusive coding genius and Amanda’s former mentor, holds a dangerous key to understanding the Ghost’s impossible methods – a manipulation of quantum cryptography so advanced it bends the laws of physics.  He warns her: the Ghost isn’t just altering the blockchain; it’s manipulating time itself.
As Amanda and Timothy delve deeper, they uncover a hidden cabal, the Ouroboros Society, obsessed with digital immortality. They believe Chimera is the key to uploading their consciousness, escaping the limitations of their physical bodies. The victims, once members, threatened to expose their secrets.
The Ghost, now aware of Amanda, turns its attention to her, blurring the lines between the digital and the physical, targeting the emotional scars of her past. The attacks become deeply personal, a twisted game of cat and mouse played out on the global stage.
With the world’s financial markets hanging in the balance, Amanda races against time to expose the killer during the final, tension-filled keynote address of Crypto Con. Armed with a dangerous piece of code from Jeffrey, she must confront not just the Ghost, but her own deepest fears, in a desperate fight for the soul of the digital age. The truth, when it emerges, will shatter everything she thought she knew about the nature of reality, revealing a chilling truth about the human cost of innovation, and the ghost in the machine.
