Skip to site navigation (Press enter) Announce: PicoLisp in Hardware (PilMCU) Alexander Burger Fri, 19 Sep 2014 04:48:35 -0700 X-Body-of-Message Hello List, we are proud to announce PilMCU, the Lisp Machine on a Chip! :) We, that is George Orais (who persuaded me into the project) and me. Georg built the actual machine in Verilog, and I did the changes and extensions to PicoLisp. PilMCU is an implementation of 64-bit PicoLisp directly in hardware. A truly minimalistic system. PicoLisp is both the machine language and the operating system: * Memory management is trivial, just the Lisp heap and the stack * The built-in database is extended to hold a "file system" * One SSD per database file for mass storage * "Processes" run as tasks and coroutines * Events (timing and interrupts) via a 'wait' instruction * Complex I/O protocols are delegated to peri...

Timelock ======== Create a secret key that can be decrypted in a known amount of time using parallel-serial hash chains. The creator can compute the timelock in parallel, taking advantage of the large amount of cheap parallelism available today, while others are forced to compute it serially, constrained by the lack of scalar performance growth. The chains are constructed such that Bitcoin addresses can be derived from them and bounties placed, incentivizing third-parties to crack the timelocks. This gives us a valuable chance to incentivize others to push the envelope of scalar performance - important knowledge if we are going to have ...
