REIST Research Token

Documented testnet pilot for the centered-remainder research project

REIST describes an implementation-oriented use of centered remainders for addition-dominated modular compute kernels. A separate ERC-20 pilot, the REIST Research Token, has been deployed on Base Sepolia and provides the technical basis for documented recognition of reproducible implementations and independent evaluations.

Classification: The method works without a token. There is no investment offering; the token confers no equity, redemption, or return rights and is not a mark of scientific quality.

Mathematical basis

Scope and invariant

Centered remainders are mathematically classical. REIST's contribution lies in their implementation-oriented use as a persistent state for addition-dominated modular compute kernels.

Small-magnitude remainder

Positive and negative deviations are represented symmetrically around zero. The remainder is interpreted as a bidirectional correction term.

Persistent invariant

If both the state and step remain centered, at most one ±B correction returns the sum to the target interval.

Hardware-friendly

Addition, comparisons, and masks enable branchless code, SIMD vectorization, and a small FPGA datapath.

Measurements and scope of validity

Reported results

All values refer to the platforms, compiler configurations, and baselines documented in the canonical German paper. They are not a general performance guarantee.

Source status: The following table comes from the canonical German paper published on Zenodo (SHA-256 369B9FB75C1B6D4C2CBBA91FF63DB4420900AB30B6EEC137BFD72290AE7D45C4), DOI 10.5281/zenodo.21206471, published on 5 July 2026 under CC BY 4.0.

FPGA sources: The VHDL implementation, GHDL testbenches, and Tang Primer 20K build files are publicly accessible. The local GHDL tests pass; the documented synthesis and hardware measurements have not been independently reproduced. An explicit root license is currently absent.

Negative and neutral controls

Pure remainder computation: scalar O3 is approximately equal; x86 SIMD is slower in the reported test.
No structural point of application in ARX code such as ChaCha20; the manuscript classifies measured throughput as unchanged.
Hash mixing is approximately 15–25% slower under O3/SIMD; O0 is substantially worse.
Without O3/SIMD, branchless REIST can be slower.

Token specification

Fixed ERC-20 model on Base Sepolia

The token is intended as a transferable means of recognizing reviewed research contributions; selection and review remain off-chain. It does not accelerate the framework. Access to the paper and code is not tied to token ownership. There is no entitlement to returns or redemption. The full specification is available at REIST Research Token (REIST) — Contract and Allocation.

Name: REIST Research Token

Genesis allocation
Purpose	Amount	Share
Research Rewards	700,000	70%
Ecosystem Treasury	200,000	20%
Founder Vesting	100,000	10%

Founder allocation: one-year cliff and three-year linear vesting. One third is vested at the cliff. The deployment reserved 0% for a public sale and 0% for DEX liquidity. This is project policy, not a technical transfer restriction.

Canonical scientific reference

DOI 10.5281/zenodo.21206471 is canonical for the token pilot. DOI 10.5281/zenodo.17897540 remains historically referenced as the earlier public version 2.0. Zenodo identifies the canonical record as a new version of that predecessor; the identifiers are not identical.

Next steps

Designate independent treasury Safes and signers.
Document the remaining checks of the full testnet smoke test.
Open the first reproduction bounty as a public issue.
Consider mainnet only after documented utility, an audit, and legal review.
