Realizing true decentralization with a ‘Self-contained’ structure that breaks away from external network dependency
PQC-based 10-byte identifier… 2x efficiency compared to existing systems, securing security for the quantum era
First transaction successful in December 2025; ‘Self-sovereignty’ philosophy directly projected onto the address system

SymVerse Labs, a company specializing in blockchain mainnets, has unveiled ‘SymID,’ a next-generation identifier standard that internalizes independent sovereignty within the address structure itself. This is evaluated as a core technology that realizes true decentralization by directly implementing ‘digital sovereignty’ — the intrinsic value of blockchain — into the address system.

A Decentralized Identifier (DID) refers to an independent sovereign identifier capable of identifying digital subjects online and offline without centralized institutions. The key is to verify identity like a fingerprint but without including personal information.

Identifiers in the existing blockchain ecosystem had the limitation of being dependent on specific network environments. According to the W3C (World Wide Web Consortium) DID standard, Ethereum-based DIDs required specifying different Chain IDs for each network (Mainnet, Ropsten, etc.) to be identifiable.

In contrast, SymVerse’s SymID adopts a ‘Self-contained’ structure that integrates the Version, Issuer ID (CA ID), and Public Key Hash within the address. This allows the address itself to prove global uniqueness without separate external settings or system assistance. This technical self-reliance serves as the foundation for a ‘Self-Sovereign Identity Authentication System’ where users fully control their identity without being bound by the rules of a specific network.

This move by SymVerse Labs aligns with the direction recently declared by Ethereum creator Vitalik Buterin. Buterin recently stated that “2026 will be the year of digital self-sovereignty recovery,” emphasizing individual rights not dependent on giant platforms or specific networks. By preemptively implementing this at the address system level, SymVerse has secured an advantageous position in the global Web 3.0 standard competition.

SymID maximizes data efficiency through an ultra-slim structure of 10 Bytes. This is half the size of existing address systems like Ethereum (20 Bytes). Assuming a 1,000 TPS environment, this results in saving approximately 20 KB of data transmission and storage capacity per second.

Such an efficient data structure goes beyond simple cost reduction; it enhances network scalability and allows more subjects to participate in the ecosystem without barriers, thereby spreading the democratic values of blockchain.

In December 2025, SymVerse Labs proved its next-generation security capabilities by successfully executing the first transaction on its testnet using SymID applied with Post-Quantum Cryptography (PQC) algorithms.

In particular, through a Dual Cryptography system implemented at the blockchain core level, it maintains compatibility with existing blockchains while securing fast processing performance of over 3,000 transactions per second. This signifies the construction of a powerful technical shield capable of protecting users’ digital sovereignty from future quantum computer attacks.

Choi Soo-hyuk, CEO of SymVerse Labs, stated, “SymID is the ‘crystallization of self-sovereignty’ that goes beyond a simple identification system to grant independence and autonomy that does not waver amidst technological environmental changes.” He added, “We will lead the mass adoption of Web 3.0, returning complete sovereignty to individuals even in the quantum computing era through a universal identifier standard that breaks down network boundaries.”
